Hello! I've seen a few users with bluetooth connectivity problems since the update to Monterey. I have had the update since 2021 and not had an issue before.
Until today, while working on my iMac (2017 21.5") for a few hours, suddenly all my bluetooth devices disconnected at the same time (I have a pair of JBL headphones, my iMac keyboard and magic mouse). The bluetooth was still on, but when I went to go into Bluetooth Preferences menu, the devices appear (all unconnected) on the listed devices for a few seconds, then the entire lists disappears alotgether. Then after a few seconds they appear again, but they disappear again before I can do anything to the devices. When trying to turn the bluetooth on or off, it freezes for a bit then eventually turns on/off.
I have tried restarting the computer, killing the Bluetooth via the terminal, deleting the bluetooth preference folder in my Library, but so far nothing has worked. I am not able to remove all the devices to try to reconnect because they disappear too quickly. I have just tried updating to the latest Monterey OS (12.4), but still no avail. Has anyone else experienced this problem? Thank you in advance!
