Can't turn on Bluetooth after upgrade to Monterey 12.3
I upgraded my iMac to Monterey 12.3 this afternoon from Monterey 12.2
Prior to upgrading I had no issues with bluetooth.
After the upgrade the bluetooth icon in the menu bar is grayed out with a slash through it. I clicked the icon, turned the toggle to 'on' in the dropdown. The toggle switched and stayed in the 'on' position, but the icon in the menu bar stayed grayed out, and no bluetooth devices worked.
I opened system preferences>bluetooth and clicked the Turn Bluetooth On button. Nothing happened.
I restarted, exact same behavior.
I opened Terminal, ran the command "sudo pkill bluetoothd", and restarted. Exact same behavior.
I went to Finder/Library/Preferences/com.apple.Bluetooth.plist, backed up that file and then dragged it out of Preferences to the Trash and restarted. Exact same behavior BUT a new com.apple.Bluetooth.plist was NOT created.
I dragged my backed up copy of com.apple.Bluetooth.plist back into Preferences.
I opened Activity Monitor and searched 'blue' to show any bluetooth processes. The only thing that shows up is "com.apple.preferences.Bluetooth.remoteservice". On my husbands MacBook (still running on Monterey 12.2) there are at least 4 bluetooth processes that show up. No matter what I click on related to bluetooth, no bluetooth processes show any activity. The only thing that changes is the toggle on the menu bar icon drop down, and it will just switch and stay in whichever position I put it in.
I created a new admin user on my iMac and replicated the exact same behavior.
Screenshot - Menu icon drop down is toggled on, but menu icon is still grayed out, and system preferences still show not turned on, no activity, plist file is in preferences
Screenshot - menu icon drop down is toggled off, no change to anything else
Screenshot - expanded info menu icon drop down is open and toggled off.... still nothing changing anywhere
Screenshot - expanded info menu icon drop down is open and toggled on... still absolutely no other changes
Anyone have any info on this happening with Monterey 12.3 or a fix for it?
