esmith1966 Posted October 30, 2021 Share Posted October 30, 2021 I have been able to install Monterey release to this laptop... But boot is extremely slow and no bluetooth... I am wondering if the bluetooth chipset is still supported... Does an unsupported bluetooth chipset slow down the boot process? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 30, 2021 Moderators Share Posted October 30, 2021 Yes, BT is not fully supported yet. Make sure you don't use IntelBlueToothInjector, but rather replace it with BlueToolFixup.kext instead. Link to comment Share on other sites More sharing options...
esmith1966 Posted October 30, 2021 Author Share Posted October 30, 2021 This is the list of KEXTs that are in my system Which ones are not correct... I disabled all the bluetooth ones and now the machine boots in normal time... But no bluetooth of course... (all the ones with Brcm...) Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 30, 2021 Moderators Share Posted October 30, 2021 Replace BrcmBluetoothInjector.kext with BlueToolFixup.kext. But it might still not work in Monterey, just have to wait for further development. See here Link to comment Share on other sites More sharing options...
esmith1966 Posted October 31, 2021 Author Share Posted October 31, 2021 Disabled all bluetooth kext Added Bluetoolfixup Reactivated BrCmPatchRam3 Now it works... THANKS for the help... Remaining issue now is related to the USB ports... Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 31, 2021 Moderators Share Posted October 31, 2021 what issue with the Ports? Link to comment Share on other sites More sharing options...
esmith1966 Posted October 31, 2021 Author Share Posted October 31, 2021 the USBPort_E7470 that is with (your) EFI package no longer activates all USB ports... (this is the kext that's found in the guide elsewhere on this site)... This is the readout from System Information. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 31, 2021 Moderators Share Posted October 31, 2021 I purposely removed the internal port for the smart card reader since it'll never be supported, waste for energy. If you want it, you can re-added. I think it's port HS07 or HS08, set connector type to 255 for internal, or use the one from my earlier bootpack.

esmith1966 Posted November 1, 2021 Author Share Posted November 1, 2021 Strange... It was working this morning. I was able to a pair my Beats headphones and my iPhone... But now it does not seem to work... The USB ports issue seems resolved... Strange Link to comment Share on other sites More sharing options...
esmith1966 Posted November 1, 2021 Author Share Posted November 1, 2021 Its very strange... Bluetooth worked... and senses (slowly) new devices.. But it does not seem to be able to connect. Unsure if it is a kext that's set to be activated or deactivated which is the issue... Link to comment Share on other sites More sharing options...
