2025-01-17: SDCard Reader in Sonoma and Sequoia… sorta…

In order for the SD Card Reader to work in macOS Sonoma and Sequoia, the Micro SD Card has to be inserted into it before booting macOS – otherwise it won't be mounted. And once an SD card is ejected, it won't mount again, after re-inserting it. These kexts haven't been updated in years, so that's why they don't work as expected no more, I guess.

• Updated OpenCore and Drivers to version 1.0.4 (nightly)
• Tested with macOS Sonoma 14.7.3 and macOS Sequoia 15.3 beta 3
• CONFIG
  • DeviceProperties
    • Changed AAPL,slot-name to build-in, where appropriate.
  • Kernel/Add
    • RealtekCardReader and RealtekCardReaderFriend kexts → Deleted MaxKernel settings, so they are loaded in macOS Sequoia
    • Updated YogaSMC.kext to v 2.0.0 (compiled it myself). I still have to figure out how to compile the corresponding prefpane – it wasn't in the "build" folder…

For deployment, follow the instructions on my repo!

Important

• Reset NVRAM before booting!
• SecureBootModel is set to Disabled! You can re-enable it after updating to macOS 14.4 or newer. Otherwise the update fails!
• Don't update the following Kexts:
  • Advancedmap → Original source is older
  • AirportItlwm → Slimmed kext
  • AppleALC → Slimmed kext
  • IntelBluetoothFirmware → Slimmed kext
  • Itlwm → Slimmed kext
