My Apple Wireless Magic Mouse does not track/move the cursor on screen, but it's connected to the iMac bluetooth. The batterys are full. I also replace them with new ones.
I can left-click, right-click, double-click, scroll and swipe with one/two fingers. You name it! Everything works, except I cannot move the cursor, it does not track at all.
I started having this problem when I went on vacation and turned the iMac off and also disconnected the power cable from the power socket for a couple of weeks. When I came back and turn it on, the Apple Wireless Mouse had this problem. But still, I could make it work if:
1) I remove the mouse from the Bluetooth Preferences list clicking the "-" (minus) button and then put it back on again in the Bluetooth Configuration Assistant.
2) After a while I noticed that after a restart I could click the mouse and I could just wait a while (3 to 5 minutes) and the mouse will start moving again, although the cursor would not track/move and behave as expected for 1 or 2 minutes (jittery, jumpy, slow, fast), but after that 1 or 2 minutes would eventually come back to normal.
The problem would return after I would Pause the iMac. After I wake him up again the Mouse was not moving again and I had to go trough the process described on step 1 or 2 to make it behave correctly again.
I think, in the beginning when I restarted the iMac in Safe Mode (keep pressing Shift in the restart process) the mouse would behave normal. So I thought that this was a software problem/conflict with some third party login files, etc. I deleted the LaunchAgents form the User Library. Didn't work. And also look inside the folder StartUpItems in the System Folder, but it was empty. But now, even if I restart in Safe Mode the mouse doesn't move. :-(
Also, I tried all of this without success:
Any ideas, please? I need help.
