How to Enable Thunderbolt 3 Hotplug on macOS [Clover/OpenCore]
An EliteMacx86 Exclusive Guide - This guide covers implementation of Thunderbolt 3 Hotplug on macOS for single and multiple Thunderbolt 3 Cards.
Overview
An EliteMacx86 Exclusive Guide - In our previous post, we covered a guide about implementation of Thunderbolt on macOS. This guide covers the implementation of Thunderbolt 3 Hotplug.
You can read about the implementation of Thunderbolt 3 here:
For more information on Thunderbolt 4 Hotplug, refer to the guide linked below.
Implementation of Hotplug with Thunderbolt has been always a major issue with macOS. But Thanks to users like KGP who has been able to implement it on the hardware. The reason with the not working of Hotplug with the Thunderbolt is due to the working style of thunderbolt on both the platform i.e. Windows and Mac. On Windows hardware, the working of Thunderbolt is different as compared to a real Macintosh.
Before getting into it, let's get to know about the working of ThunderBolt on Mac and Windows hardware which will help you to understand about the working of Hotplug.
On Windows hardware, the Thunderbolt is only powered up when any Thunderbolt compatible Device is connected. The device triggers the thunderbolt to function and turns on the power to the connected device. Once, it's disconnected, the power to the port is also turned off.
On the other hand, on Mac, it's not the same. On Mac, the Thunderbolt is always on until the system is turned off. When any device is connected to the Thunderbolt port, the Device automatically connects to the thunderbolt and this is the reason the hotplug basically works. The Thunderbolt is always active as it keeps drawing the power.
On the Hackintosh, it's little bit different or you can say, it's mixed. The thunderbolt will function only if the device is connected before booting to macOS i.e preboot mode. If you disconnect it, the device no longer function and you need to restart the system again. Hence, the system is not capable of Hotplug.
But by using this guide, you would be able to implement Hotplug.
Requirements
Enabling hotplug can be quite complex process and time consuming. But if done correctly, you can have a working Thunderbolt with hotplug feature with the required speed and performance.
Following are the test devices used as an example for this guide which features Audio Interfaces, Dock, and Thunderbolt Drives. From consumer series to HEDT series motherboard, it works as expected.

Thunderbolt Firmware Configuration
There can be normally two firmware configuration for Thunderbolt 3. Original and Custom firmware Configuration. Both of them have been described below.
Original Firmware:
A original firmware is provided and is already flashed on the Thunderbolt Card. When you setup multiple Thunderbolt Cards, only one Card will work in a desired way and the other cards will not work due to limitation of different device address.
Custom Firmware:
A custom firmware is modified some of the experts from this community which eliminates the limitation of Thunderbolt Cards with different device addresses and also provides additional function such as Thunderbolt Bus configuration, visibility under System Report>Thunderbolt.
Thunderbolt Configuration
There can be normally two configuration for Thunderbolt 3. Single Card and Multiple Card Configuration. Where, single card offers up to "two" thunderbolt 3 ports and multiple card can offer up to "twelve" thunderbolt 3 ports depending on the PCIe slots available where one slot is always reserved for the GPU. These can be further categorized into four more configuration which are outlined below.
Single Card with Original Firmware:
A single Card with original firmware can offer up to "two" Thunderbolt 3 ports which doesn't requires flashing of a custom firmware for macOS.
Single Card with Custom Firmware:
A single card with original firmware can offer up to "two" Thunderbolt 3 ports which requires flashing of a custom firmware for macOS. With a custom firmware, it can provide additional function, visibility and additional information of Thunderbolt under System Report>Thunderbolt section.
Multiple Card with Original Firmware:
Multiple cards with original firmware can range between two (minimum) or more (up to 6, maximum) Thunderbolt card installed. HEDT and Workstation motherboards can offer up to 7 PCIe slots. However, one slot is reserved for GPU. Hence, the maximum capacity is six Thunderbolt 3 Cards. The drawback of using multiple cards with original firmware is that other than the reserved slot for Thunderbolt or small peripherals where the device address is usually PXSX, will be initialized and fully work, more likely like a single card with custom firmware. The rest of the cards installed will not function in any way. This is because, unless the card is flashed with a custom firmware, the Thunderbolt cannot be driven due to having different address such as BR1A, BR3A, PEGP, SL01, SL09.
Multiple Card with Custom Firmware:
Multiple cards with custom firmware can be best suited to professional music producers, video editors, motion and VFX artists. This option offers the maximum expandability of Thunderbolt 3. Offering up to 12 ports when 6 Thunderbolt Card is installed which is a maximum configuration as of now. Note that one slot is always reserved for GPU. With a custom firmware flashed on multiple Thunderbolt Card, it removes the limitation of utilizing multiple Thunderbolt cards. It also offers functionality such as Hotplug which can be achieved very easily.
Selecting Thunderbolt Configuration
Depending on your need for Thunderbolt, where the key factor can be the requirement of each individual Thunderbolt 3 ports, select your configuration and start the preparation for Thunderbolt 3 Hotplug. If you're looking for a simple Thunderbolt with Hotplug functionality and don't want to flash a custom firmware due to the complexity of the guide or not willing to take risk, the best choice would be to go for single card with original firmware. However, even if you don't want to flash your Thunderbolt with a custom firmware, you may need to flash it for some devices which requires Thunderbolt Bus to utilize a particular Thunderbolt device.
Flashing Custom Firmware
If you're planning to flash the custom firmware depending on your Thunderbolt needs, @mooseknuckleboi has written a very well guide explaining flashing Thunderbolt Cards for macOS. You can find more information for his thread linked below.
Enabling Thunderbolt 3 Hotplug
Now, you have enough information about Thunderbolt configuration, firmware, and the limitations and the next step is to enable Thunderbolt Hotplug To enable Hotplug, follow the steps outlined below.
Getting ACPI path
Before you start preparing the SSDT, it's recommended to find the ACPI path of the Thunderbolt Card.
For Single Card and Onboard Thunderbolt:
Connect any TB device and boot the system in order to get the ACPI path for the Thunderbolt Card on your Motherboard.
Now once the system is up, the next step is to get the ACPI path. To check the ACPI path, just open IOReg and type Thunderbolt in the search bar.
You should see something similar like in the attached screenshot.
Once you have located Thunderbolt node, you can clear the search to get the complete node info.
If you check, in the above screenshot, we have some Thunderbolt and USB connectors listed. You need to locate your current connector which is driving the connection to the Thunderbolt. A simple way to find this out is to just find the connector having Thunderbolt properties with AppleThunderboltHAL. In our case, it is RP21@1B,4. Your system can have a different one. Make sure to locate the right one.
For Multiple Cards:
Getting ACPI path is bit complex than single and onboard Thunderbolt. Follow the steps below.
You can install all the Thunderbolt Cards and get multiple ACPI path or can also use one card in each particular slot and then get the ACPI path.
To check the ACPI path, just open IOReg and type Thunderbolt in the search bar.
In our case, here are the following ACPI path
For Slot #2
However, this is the first phase of the ACPI path. To complete the second phase, you'll need to use a Thunderbolt SSDT and adapt for the every slot except PXSX and note down the new ACPI path. Note that normally it's PEGP. However, we recommend you to go through the second phase and confirm the ACPI path to make sure there is no fluke.
For Slot #3
Obtaining Sample Thunderbolt SSDT
To get the sample Thunderbolt SSDT, follow the steps below.
1. Open HackinDROM website in your web browser.
2. Select your Thunderbolt Controller from the drop-down list.
3. You'll see the list of available Motherboards and AIC like the screenshot attached below. The list is subject to change.
For Single Card and Onboard Thunderbolt:
If you're having an onboard Thunderbolt chip or a single Thunderbolt Card, just select the appropriate model from the list.
For Multiple Thunderbolt Card:
If you're having multiple Thunderbolt Card, the process will be bit different from the onboard and single Thunderbolt card.
1. Select the appropriate AIC model from the list.
Configuring TB Bus ID
For each Thunderbolt Card, you'll need to configure the TB Bus ID. This is necessary for multiple Thunderbolt Controllers installed in the system. Each unique Bus ID represents each unique Thunderbolt Controller. To configure the Bus ID, follow the steps below.
1. After selecting the AIC model from the list, click on Customize.
2. Under TB Bus ID, change the Bus ID. You can use Bus ID from 0 or 1, where the 0 or 1 belongs to the first Thunderbolt Card. For example, if you have 3 Thunderbolt Cards and you would like to use the TB Bus from 0, it would 0, 1 and 2 respectively and if you would like to use the TB Bus from 1, it would be simply 1, 2 and 3 respectively.
3. Once you've selected the TB Bus ID, click on COMPILE button.
4. Click on Download button and the SSDT will be downloaded/saved to your system's configured download location in your browser.
Note:
Now, we have got the ACPI path of the Thunderbolt. To enable the hotplug, you must change the ACPI path to match yours.
1. Open the downloaded SSDT
For Single Card and Onboard Thunderbolt:
For single card and onboard Thunderbolt, the steps are very simple.
If we consider our first Thunderbolt Card, which is installed on Slot #2 as the Slot #1 is reserved for GPU, the changed to the SSDT, would be the following.
2. Click on Replace checkbox in the right corner.
3. Type PCI0 in the first search box and type PC00 in the second search box.
4. Click on All and the changes would be like the screenshot attached below.
Notes:
For Multiple Thunderbolt Cards:
For Multiple Thunderbolt Cards, you'll need to perform some additional steps.
If we consider our second Thunderbolt SSDT, here would be the changes.
2. Click on Replace checkbox in the right corner.
3. Type PCI0 in the first search box and type PC01 in the second search box.
4. Click on All and the changes would be like the screenshot attached below.
5. Type RP21 in the first search box and type BR1A in the second search box.
6. Click on All and the changes would be like the screenshot attached below.
8. Click on All and the changes would be like the screenshot attached below.
Adding additional External Definition Block
If you remember the step of "Getting ACPI Path", you may have noticed that for second Thunderbolt Card, the path was PC01.BR1A.SL01 but here we have been using PEGP. Hence, we need to add PC01.BR1A.SL01 and also define SL01. To do that, follow the steps below.
1. Copy the following External method.
2. Paste it just above the External (DTGP) line.
Once changed, the SSDT should look like the screenshot attached below.
3. Copy the following Scope
4. Paste it just above the "Scope (PEGP) line.
Once changed, the SSDT should look the screenshot attached below.
Click on Compile button and save the SSDT.
Note:
Slot Configuration
The slot configuration is purely cosmetic but is helpful when debugging and makes the Thunderbolt nearly perfect. The slot counts will be from the very slot present on the Motherboard, regardless of the slot type. There can be three slot configuration for Thunderbolt 3. Onboard and Single/Multiple Thunderbolt
Onboard Thunderbolt:
For onboard Thunderbolt, the slot will be configured as "built-in" due to onboard chip directly soldered on the Motherboard. For onboard Thunderbolt configuration, the sample SSDT should be good to go as it's already configured as built-in.
Singe/Multiple Thunderbolt Card:
For single or multiple Thunderbolt, the slot will be configured as Slot-1, Slot-2 and so on. To change the Slot configuration, follow the steps below.
If we consider our first sample SSDT, which refers to the very first Thunderbolt Card installed in Slot #2, the changes would be the following.
The sample SSDT has Slot-4 as a configuration and the changes would be the following.
Note:
Renaming SSDT
If you're using multiple Thunderbolt Card, it's strongly recommended to rename the SSDTs as SSDT-TB3-SLOT1, SSDT-TB3-SLOT2 and so on.
Installing the SSDT
Now, the SSDT has our ACPI path. The next step is to install the SSDT.
1. Mount the EFI partition of the system
2. Open the EFI folder.
For OpenCore:
1. Navigate to EFI/OC/ACPI/patched directory.
2. Place the SSDT-DTGP and the related SSDT-TB3-SLOT-X.
For Clover:
1. Navigate to EFI/Clover/ACPI/patched directory.
2. Place the SSDT-DTGP and the related SSDT-TB3-SLOT-X.
Notes:
Restart your System
After performing all the above steps, restart your system for the applied changes to take effect.
Connect any TB Device and you're good to go!

Thunderbolt Firmware Configuration
There can be normally two firmware configuration for Thunderbolt 3. Original and Custom firmware Configuration. Both of them have been described below.
Original Firmware:
A original firmware is provided and is already flashed on the Thunderbolt Card. When you setup multiple Thunderbolt Cards, only one Card will work in a desired way and the other cards will not work due to limitation of different device address.
Custom Firmware:
A custom firmware is modified some of the experts from this community which eliminates the limitation of Thunderbolt Cards with different device addresses and also provides additional function such as Thunderbolt Bus configuration, visibility under System Report>Thunderbolt.
Thunderbolt Configuration
There can be normally two configuration for Thunderbolt 3. Single Card and Multiple Card Configuration. Where, single card offers up to "two" thunderbolt 3 ports and multiple card can offer up to "twelve" thunderbolt 3 ports depending on the PCIe slots available where one slot is always reserved for the GPU. These can be further categorized into four more configuration which are outlined below.
Single Card with Original Firmware:
A single Card with original firmware can offer up to "two" Thunderbolt 3 ports which doesn't requires flashing of a custom firmware for macOS.
Single Card with Custom Firmware:
A single card with original firmware can offer up to "two" Thunderbolt 3 ports which requires flashing of a custom firmware for macOS. With a custom firmware, it can provide additional function, visibility and additional information of Thunderbolt under System Report>Thunderbolt section.
Multiple Card with Original Firmware:
Multiple cards with original firmware can range between two (minimum) or more (up to 6, maximum) Thunderbolt card installed. HEDT and Workstation motherboards can offer up to 7 PCIe slots. However, one slot is reserved for GPU. Hence, the maximum capacity is six Thunderbolt 3 Cards. The drawback of using multiple cards with original firmware is that other than the reserved slot for Thunderbolt or small peripherals where the device address is usually PXSX, will be initialized and fully work, more likely like a single card with custom firmware. The rest of the cards installed will not function in any way. This is because, unless the card is flashed with a custom firmware, the Thunderbolt cannot be driven due to having different address such as BR1A, BR3A, PEGP, SL01, SL09.
Multiple Card with Custom Firmware:
Multiple cards with custom firmware can be best suited to professional music producers, video editors, motion and VFX artists. This option offers the maximum expandability of Thunderbolt 3. Offering up to 12 ports when 6 Thunderbolt Card is installed which is a maximum configuration as of now. Note that one slot is always reserved for GPU. With a custom firmware flashed on multiple Thunderbolt Card, it removes the limitation of utilizing multiple Thunderbolt cards. It also offers functionality such as Hotplug which can be achieved very easily.
Selecting Thunderbolt Configuration
Depending on your need for Thunderbolt, where the key factor can be the requirement of each individual Thunderbolt 3 ports, select your configuration and start the preparation for Thunderbolt 3 Hotplug. If you're looking for a simple Thunderbolt with Hotplug functionality and don't want to flash a custom firmware due to the complexity of the guide or not willing to take risk, the best choice would be to go for single card with original firmware. However, even if you don't want to flash your Thunderbolt with a custom firmware, you may need to flash it for some devices which requires Thunderbolt Bus to utilize a particular Thunderbolt device.
Flashing Custom Firmware
If you're planning to flash the custom firmware depending on your Thunderbolt needs, @mooseknuckleboi has written a very well guide explaining flashing Thunderbolt Cards for macOS. You can find more information for his thread linked below.
GUIDE - How to Flash Custom Firmware on Thunderbolt Card for macOS
How to Flash Custom Firmware on Thunderbolt Card for macOS Overview Following is a Thunderbolt firmware flashing guide exclusively for macOS. The guide is applicable for Motherboards having Built-In Thunderbolt, Laptops and Add-In Cards. The method is tested by us on the following Add-In...

Enabling Thunderbolt 3 Hotplug
Now, you have enough information about Thunderbolt configuration, firmware, and the limitations and the next step is to enable Thunderbolt Hotplug To enable Hotplug, follow the steps outlined below.
Getting ACPI path
Before you start preparing the SSDT, it's recommended to find the ACPI path of the Thunderbolt Card.
For Single Card and Onboard Thunderbolt:
Connect any TB device and boot the system in order to get the ACPI path for the Thunderbolt Card on your Motherboard.
Now once the system is up, the next step is to get the ACPI path. To check the ACPI path, just open IOReg and type Thunderbolt in the search bar.
You should see something similar like in the attached screenshot.
Once you have located Thunderbolt node, you can clear the search to get the complete node info.
If you check, in the above screenshot, we have some Thunderbolt and USB connectors listed. You need to locate your current connector which is driving the connection to the Thunderbolt. A simple way to find this out is to just find the connector having Thunderbolt properties with AppleThunderboltHAL. In our case, it is RP21@1B,4. Your system can have a different one. Make sure to locate the right one.
For Multiple Cards:
Getting ACPI path is bit complex than single and onboard Thunderbolt. Follow the steps below.
You can install all the Thunderbolt Cards and get multiple ACPI path or can also use one card in each particular slot and then get the ACPI path.
To check the ACPI path, just open IOReg and type Thunderbolt in the search bar.
In our case, here are the following ACPI path
For Slot #2
For Slot #3
For Slot #5
However, this is the first phase of the ACPI path. To complete the second phase, you'll need to use a Thunderbolt SSDT and adapt for the every slot except PXSX and note down the new ACPI path. Note that normally it's PEGP. However, we recommend you to go through the second phase and confirm the ACPI path to make sure there is no fluke.
For Slot #3
For Slot #5
Obtaining Sample Thunderbolt SSDT
To get the sample Thunderbolt SSDT, follow the steps below.
1. Open HackinDROM website in your web browser.
2. Select your Thunderbolt Controller from the drop-down list.
3. You'll see the list of available Motherboards and AIC like the screenshot attached below. The list is subject to change.
For Single Card and Onboard Thunderbolt:
If you're having an onboard Thunderbolt chip or a single Thunderbolt Card, just select the appropriate model from the list.
For Multiple Thunderbolt Card:
If you're having multiple Thunderbolt Card, the process will be bit different from the onboard and single Thunderbolt card.
1. Select the appropriate AIC model from the list.
Configuring TB Bus ID
For each Thunderbolt Card, you'll need to configure the TB Bus ID. This is necessary for multiple Thunderbolt Controllers installed in the system. Each unique Bus ID represents each unique Thunderbolt Controller. To configure the Bus ID, follow the steps below.
1. After selecting the AIC model from the list, click on Customize.
2. Under TB Bus ID, change the Bus ID. You can use Bus ID from 0 or 1, where the 0 or 1 belongs to the first Thunderbolt Card. For example, if you have 3 Thunderbolt Cards and you would like to use the TB Bus from 0, it would 0, 1 and 2 respectively and if you would like to use the TB Bus from 1, it would be simply 1, 2 and 3 respectively.
3. Once you've selected the TB Bus ID, click on COMPILE button.
4. Click on Download button and the SSDT will be downloaded/saved to your system's configured download location in your browser.
Note:
- To activate Thunderbolt Bus, you'll need to flash a custom firmware onto your Thunderbolt Card.
- For multiple Thunderbolt Cards, it's strongly recommended that you refresh the website and configure the TB Bus ID for each card to generate random Unique ID (UID) respectively.
- The Slot having PXSX address, is recommended to have TB Bus ID as 0. The rest should have 1, 2, 3 and so on.
Now, we have got the ACPI path of the Thunderbolt. To enable the hotplug, you must change the ACPI path to match yours.
1. Open the downloaded SSDT
For Single Card and Onboard Thunderbolt:
For single card and onboard Thunderbolt, the steps are very simple.
If we consider our first Thunderbolt Card, which is installed on Slot #2 as the Slot #1 is reserved for GPU, the changed to the SSDT, would be the following.
1. To change that, press Command+F on your Keyboard.
2. Click on Replace checkbox in the right corner.
3. Type PCI0 in the first search box and type PC00 in the second search box.
4. Click on All and the changes would be like the screenshot attached below.
Notes:
- The rest of the path will not be changed as per the IOReg, the ACPI path for the very first Card, for Slot #2, was PC00.RP21.PXSX.
- For the Slot having PXSX as a path in IOReg, no further SSDT modification is required.
For Multiple Thunderbolt Cards:
For Multiple Thunderbolt Cards, you'll need to perform some additional steps.
If we consider our second Thunderbolt SSDT, here would be the changes.
1. To change that, press Command+F on your Keyboard.
2. Click on Replace checkbox in the right corner.
3. Type PCI0 in the first search box and type PC01 in the second search box.
4. Click on All and the changes would be like the screenshot attached below.
5. Type RP21 in the first search box and type BR1A in the second search box.
6. Click on All and the changes would be like the screenshot attached below.
7. Type PXSX in the first search box and type PEGP in the second search box.
8. Click on All and the changes would be like the screenshot attached below.
Adding additional External Definition Block
If you remember the step of "Getting ACPI Path", you may have noticed that for second Thunderbolt Card, the path was PC01.BR1A.SL01 but here we have been using PEGP. Hence, we need to add PC01.BR1A.SL01 and also define SL01. To do that, follow the steps below.
1. Copy the following External method.
Code:
External (_SB_.PC01.BR1A.SL01, DeviceObj) // (from opcode)Once changed, the SSDT should look like the screenshot attached below.
3. Copy the following Scope
Code:
Scope (SL01)
{
Name (_STA, Zero) // _STA: Status
}Once changed, the SSDT should look the screenshot attached below.
Click on Compile button and save the SSDT.
Note:
- You must replace the ACPI path with yours for each Thunderbolt Card installed in your system.
Slot Configuration
The slot configuration is purely cosmetic but is helpful when debugging and makes the Thunderbolt nearly perfect. The slot counts will be from the very slot present on the Motherboard, regardless of the slot type. There can be three slot configuration for Thunderbolt 3. Onboard and Single/Multiple Thunderbolt
Onboard Thunderbolt:
For onboard Thunderbolt, the slot will be configured as "built-in" due to onboard chip directly soldered on the Motherboard. For onboard Thunderbolt configuration, the sample SSDT should be good to go as it's already configured as built-in.
Singe/Multiple Thunderbolt Card:
For single or multiple Thunderbolt, the slot will be configured as Slot-1, Slot-2 and so on. To change the Slot configuration, follow the steps below.
If we consider our first sample SSDT, which refers to the very first Thunderbolt Card installed in Slot #2, the changes would be the following.
The sample SSDT has Slot-4 as a configuration and the changes would be the following.
1. Type Slot-4 in the first search box and type Slot-2 in the second search box and click on All.
Note:
- When having a multiple Thunderbolt Card, the same steps will be applied as above to the rest of the SSDTs.
Renaming SSDT
If you're using multiple Thunderbolt Card, it's strongly recommended to rename the SSDTs as SSDT-TB3-SLOT1, SSDT-TB3-SLOT2 and so on.
Installing the SSDT
Now, the SSDT has our ACPI path. The next step is to install the SSDT.
1. Mount the EFI partition of the system
2. Open the EFI folder.
For OpenCore:
1. Navigate to EFI/OC/ACPI/patched directory.
2. Place the SSDT-DTGP and the related SSDT-TB3-SLOT-X.
For Clover:
1. Navigate to EFI/Clover/ACPI/patched directory.
2. Place the SSDT-DTGP and the related SSDT-TB3-SLOT-X.
Notes:
- For OpenCore, you'll need to add the SSDTs entry in the ACPI section of your config.plist.
- The SSDTs must be added in a sorted order.
- In case of Multiple Thunderbolt Cards, it's recommended to load the SSDT with Bus 0 first and then the rest of the Thunderbolt SSDTs.
- For Hotplug to work with Alpine Ridge Cards, Thunderbolt Header must be disconnected from THB_C Header.
Restart your System
After performing all the above steps, restart your system for the applied changes to take effect.
Connect any TB Device and you're good to go!
