le0nardwashingt0n Posted November 4, 2021 Share Posted November 4, 2021 I had a well working Big Sur installation, with very few issues. I recently upgraded to Monterey and it installed with relative ease. My issue now, and I haven't seen anything on the forums about this, is that only my Macintosh Hard Drive shows up. It seems that any drives that aren't APFS aren't being acknowledged by my system. If I plug in a USB it doesn't even recognize it. I tried disabling SIP but that makes no difference. Anyone else having this issue and knows of a fix? I'm on Opencore 0.7.5 and my computer details are in my signature.

mnfesq Posted November 8, 2021 Share Posted November 8, 2021 (edited) Have you updated your HFSPlus.efi or other HFS+ driver lately? Have you checked to see if you have more than one driver for HFS+? Do you have an NTFS.efi driver? If you want to add Clover along with bootloader chooser, you can see if that makes a difference as well. Check and see if it makes any difference.

le0nardwashingt0n Posted November 9, 2021 Author Share Posted November 9, 2021 thanks for all the assistance with this one. i actually found the cause. When I upgraded I kept the intelbluetooth kexts in the EFI folder, the ones that were used in Big Sur. Removing them and applying the correct fix for intel bluetooth in monterey fixed the missing drives, returned boot speeds, and fixed bluetooth. https://github.com/OpenIntelWireless/IntelBluetoothFirmware/releases/tag/v2.0.1 Link to comment https://www.insanelymac.com/forum/topic/349516-not-able-to-use-any-non-apfs-drives-after-monterey-update/#findComment-2771419 Share on other sites More sharing options...
