Does wifi and Bluetooth function normally?
I upgrade the OS in my iMac 2009 (iMac 11,1) to Monterey but Wifi and Bluetooth don't work.
I plan to install Big Sur if the stock Wifi and Bluetooth modules work.
Yes, both work fine.
The misbehaviour I report appears to be user account related.
I tried a fresh installation with the OCLP 1.4.2 - which has fixed your problem, but did not fix mine!
Summary:
1. I fresh installed High Sierra on brand new 2TB SSD, installed in the iMac
2. Installed Big Sur via OCLP 1.4.2 configured for iMac11,1
3. Ensured root patches were NOT installed, as advised for next step
4. Ran Migration Assistant for just one administrator user account from old 1TB SSD that had been running Mojave using Dosdude1's macOS Mojave Patcher
At first boot or few, everything looked fine. After installing OCLP root patches and a Safari update, at first the Apple Menu bar and left hand Menu Bar items disappeared, but I could still select options from them by moving cursor "blind" to the appropriate positions and either left or right clicking mouse to reveal the options.
After a re-boot or two more, the behaviour became more visually consistent, but effectively locked me out of the Apple Menu and left hand Menu Bar. Now I just get Desktop Menu starting with New Folder, clicking where Apple Menu or left hand Menu Bar items should be.
A complete, unusable mess!
