[Nixgehtmehr]

Attach your EFI to check. What brand did you purchase and how have you connected the display? Also, is it a new or used unit?

Done, but how can I upload a complete EFI Folder?

Your configuration is not as per the guide.

Here are a few issues

Make the following changes to your config.plist

- The SSDT loading order is not correct. Important SSDTs should load first.
- Remove ResetLogoStatus Quirk in ACPI>Quirks section.
- Remove the entries from ACPI>Delete section.
- Remove the entries from ACPI>Patch section.
- Remove the entries from Booter>MmioWhitelist section.
- Remove the entry from Booter>Patch section.
- Remove all the Device Properties from DeviceProperties>Devices section
- Remove FakePCIID related kexts.
- Set the Kexts Arch to Any and remove MinKernel for all kexts.
- Enable DisableIoMapper in Kernel>Quirks.
- Remove the entry from Kernel>Block section.
- Remove the entry from Kernel>Force section.
- Remove the entries from Kernel>Patch section.
- Enable AppleDebug and ApplePanic in Misc>Debug section.
- Remove the entry from Misc>Entries section.
- Remove the entry from Misc>Tools section.
- Remove #INFO (prev-lang:kbd) key from NVRAM>7C436110-AB2A-4BBB-A880-FE41995C9F82 section.
- Disable SIP using 67000000 as csr-active-config value.
- Drivers loading order is not correct. Important Drivers should load first.
- Remove the entries from UEFI>Reserved Memory section.

Once you're done with the changes, save your config.plist. Restart the system and reset NVRAM twice. Attach the new PR files.

Thanks a lot for help.

I changed the EFi according your suggestions, beside the kext order - I dont know what is best to load first.

You can find the reworked EFI here:

EFI - Google Drive

drive.google.com

Computer starts with this reworked EFI - but lags are still present :-(

Remove the following bootargs:
keepsyms=1 debug=0x100 alcid=1 dk.e1000=0 shikigva=80 shiki-id=Mac-7BA5B2D9E42DDD94

Once you're done with the changes, save your config.plist. Restart the system and reset NVRAM twice. Attach the new PR files and also include a video for the lags you have. Use light theme.
