Whenever I change the batteries in my Mac’s Bluetooth mouse, the computer doesn’t connect to it again automatically. How do I force it to remember this thing exists?
A: Apple’s Bluetooth wireless-enabled Magic Mouse is supposed to link back up to a Mac on its own after a change of batteries. But when it doesn’t, instructing a Mac to reconnect to that rodent using only keyboard commands is an utterly excruciating process.
I shared some tips about resolving this kind of issue in November, but then I found that they weren’t helping on my own iMac. A tip I got from readers after that article ran — hold down the mouse button for a few seconds to force a reconnect — didn’t work either.
But a different remedy, unmentioned in Apple’s own advice, now seems to have cured the problem.
The trick is to go deep into Mac OS X’s system settings.
