Struggling with Dell XPS 9300

It won't. Those are completely unsupported NVMe. Also, how did you flash different firmware for OEM drives such as SK Hynix?

They provide a tool called SKHynix NVME Toolbox. There are 3 slots to install 3 different firmware version.

Aware of the tool. But SK Hynix never distributes the firmware for OEM models, only retail models. The firmware varies from different manufacturers, which is based on the machine models.

Well, using SK Hynix PC801 OEM on macOS Sequoia and have been running since Big Sur. Works fine. xD

That's nice to hear. While waiting for new SSD to arrive, i took a TeamGroup MP33 of my friend for a test and still get the same "macOS Installer" boot loop at phase 2 . I'm not using NVMEfix.kext, can efi cause this error?

fixed: By disable EFI -> Quirks -> DisableSecurityPolicy then set SecureBootModel to "Disabled"
Now the problem are screen brightness not adjustable, trackpad superslow, not smooth and poor performance

Why my trackpad very buggy, full gestures still recognized. Also, max screen brightness is low, but after sleep, screen brightness back to normal.

NVMeFix is really not needed. In fact, it can cause problems on some of the NVMe drives. Only use where required. Since macOS Big Sur and Monterey, the NVMe game has changed on macOS.

Yes, for Sonoma 14.5 and later, the fix was already discussed on this forum

You must implement PNLF for backlight function. You'll need to map the keys as well.

Was the performance fine earlier? And earlier what SSD did you use?

Why are you using multiple USBX?

Backlight seems to be implemented. The backlight doesn't work or you're unable to control via Hotkeys?

Really? let me remove it!
Sleep/wake is fine. Brightness is now work, but i feel it's not bright as windows. I usually use 30-40% brightness on windows but almost max brightness in Mac(still feel too dark).

Performance seems to be okay, I did a geekbench 6 test here: https://browser.geekbench.com/v6/cpu/6648146
I temporarily took my friend TeamGroup MP33, it's okay, TRIM supported.

The only problem now is the trackpad, i can't process to next step of fixing trackpad because i can't find APCI ID in IOreg like this, it didn't show up.


They said i need to patch DSDT but when i compiled my DSDT using MacIasl, i always got this error:

Double check your PNLF SSDT.

IoInterruptSpecifiers is what you're looking for

What's the patch and where are the original AML files?
