Hello Folks,
I just upgraded to Monterey and BT stopped working. When I open preferences I am getting a message "Preferences error" "could not load bluetooth pane". I can't see the reset bluetooth option in the menu.
I have tried reboots, resetting SMC and also deleting the bluetooth.plist files etc., with no luck. I now really regret upgrading to Monterey.
Anyone has any insight into resolving this?
thanks

The "reset" option is gone in Monterey.... it used to be Shift Option Keys and click open the BT icon in the Upper right menu bar
I would try a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test.
Reboot and test will take a little longer as caches get rebuilt.

Leroy,
Thank you for taking time to respond to my questions. Prior to reading your post, I was in touch with Apple chat support and they recommended I reinstall the OS. I have ordered an external hard drive to take a backup before the reinstall. But I am going to give your suggestion a try before the intall. I will report back.
thanks!
Did you do a full re-install (erase and install)? I had the same problem and the only fix that worked for me was the complete re-install. You should also run the diagnostic test (press D when restarting) to make sure there are no hardware issues, before doing the re-install. This took me several hours, but I can confirm that Bluetooth was fully functional again.
Note that in addition to the BT pane not loading, I also couldn't load Mouse/Trackpad panes, but they just hung with a spinning ball instead of reporting an error.
Yes, I had to scratch the hard-drive and then reinstall the OS after exhausting all other possible solutions. After that the BT started working fine.
(On a side note, I backed up my laptop data onto a new external hard drive prior to the reformatting, but unfortunately that hardrive broke when I tried to retrieve the data, so I lost all the data and had to start from scratch. Luckily critical personal files were saved on the cloud, but everything else was gone!!)
Now recently the Wifi quits working occasionally when I try to use the laptop after putting it to sleep. I am really frustrated and regret upgrading to Monterrey. Apple Inc. must do a better job of testing it before releasing these updates.
I hope you are able to fix your mouse/trackpad issues.
@SalTheCat The full re-install worked for me (Bluetooth, Mouse, Trackpad panes all work perfectly). Unfortunately I had to do it twice (taking many hours longer) because the first time when erasing my Fusion drive it was split into two overlapping drives and I couldn't identify this until after the restore. I had to reset the Fusion drive before the second re-install.
Bluetooth works after the reformat of hardrive and upgrade again to Monterey. However there are sporadic issues with it. At times it has difficulty connecting to devices. Today- all of a sudden the BT preferences would not open up. Had to reset the BT manually from terminal- after a while it started working again.
Ah, okay. My suggestion makes no sense to me all but it did work. Someone on some other Mac help site suggested unplugging all USB devices and rebooting then plug whatever USB devices you're using, back in. I know USB has noting to do with Bluetooth but it did solve my Bluetooth issues as well and an issue I was having with opening DMG files (I couldn't) and computer not recognizing my external hard drives -all working properly now. Good luck!
OK USB was not an issue for me. I don't use any USB devices on a daily basis. And when I do plug them in I have experienced no issues with BT. So this may be issues that arises on a case by case basis.
So trying safemode did not help. Next is to re-install OS.
I re-intalled the Monterey OS, but that did not solve the problem unfortunately.
Did you ever get this worked out? I just had the same problem and found a fix and now I'm searching the forums for the same problem, spreading the good news and offering my solution.
Bluetooth preferences not working (unable to load pane)
