vamose Posted May 27, 2021 Share Posted May 27, 2021 (edited) Apple Bluetooth Keyboard (MC184LL/A) is behaving strange. On system start/ restart, the keyboard works fine. If I put the system to sleep, upon wake up the keyboard is not identified nor can I pair it. But if I put the computer to sleep again and upon wake the keyboard is fully operational. I have tried the following: Deleted /Library/Preference all the Bluetooth related .plist. Deleted /.Library/Preference all the Bluetooth related .plist.no success Tried to reset the module, as well as factory reset, no success either. In OpenCore 0.6.9, tried USBInjectAll kext and xhciportlimit set to True Discover ports using USBMap tool, plugging in a USB 3/USB 2 hub to map ports Select SS and HS ports so total is under 15 Create Kext of new USB map Remove USBInjectAll kext and replace with USBMap kext, update config.plist Set xhciportlimit to False Reboot no success Have also tried to change S2/ S3 state in BIOS for USB. no success Logitech mouse connected to the USB via its own receiver works flawless throughout.
