Using a Bluetooth mouse or keyboard with your Mac and having issues with it disconnecting all the time after upgrading to OS X Lion? Well you’re not alone! It’s definitely some issue with Lion and it’s not yet been fixed in 10.7.2! So what can you do? Well, there are some cheap attempts at fixing this problem which have worked for a few, but not many.
We’ll mention the ones we know here and we’ll keep updating this post as more fixes come in. Feel free to post your slurs or solutions here!
Go to your Bluetooth settings in System Preferences and try to delete the paired device and then re-pair it.
Either click the + icon to add a new Bluetooth device or click Setup New Device. A few people have reported that their Bluetooth device stops disconnecting all the time once they re-pair it. If you’re not so lucky, you can try the next possibility.
Another thing you can try is to go to Advanced from the Bluetooth preferences dialog and check the box that says “Allow Bluetooth devices to wake this computer“. A lot of people are having issues with their Bluetooth device after their computers come back from Sleep mode. Instead of automatically reconnecting, you have to re-pair the mouse or keyboard, which is plain annoying.
You might get lucky with this one, but if not, you’re kind of running out of options at this point. The next thing you can try is to check and make sure that you device is not connected to any other machine by accident. This is rare, but can occur and cause problems with your device connecting properly.
Also, try to re-pair it with your Mac, but make sure that the device is in discoverable mode. If you had it connected to something else earlier, there is a chance that it will automatically start trying to connect to the old device once it disconnects from your current device.
As a last ditch effort, you can try and delete the Bluetooth preference file:
You’ll have to go to the Library folder and then the Preferences folder. If it’s not visible, go to Terminal and type the following command:
chflags nohidden ~/Library
That’ll make the Library folder visible. If you don’t see a .plist file, then you’re out of luck. But if you do, delete it and try again. Hopefully, your disconnecting or not reconnecting issue will be gone.
What you can also try is to only use one Bluetooth device at a time and see if your issue goes away. For example, if you have a Magic Mouse, go ahead and disconnect your keyboard or delete it from the Bluetooth profile altogether and then see how your mouse acts. Does it remain connected now?
If this is the case, it could be interference between the devices. Why would it start happening after upgrading to Lion and not before? No idea, but if it fixes the problem, great! Maybe Lion forces the devices to use a similar channel, which causes a conflict or something.
Some people have found luck by removing the batteries from their Bluetooth device and then either adding them back in or adding brand new ones in. This might cause Lion to rediscover the device properly and somehow fix the issue.
One final thing you can try is to completely shut down your Mac, not just restart, but total shutdown. Leave it off for about a minute and then turn it back on and see if the pairing issue goes away.
If you have any other solutions at this point, post them here! Thanks!
