Q: Cursor is moving by itself
I normally use external mouse rather than trackpad. Within the last 7 days, my cursor started to move around and change screens, opening and closing apps until the Mac is closed. The mouse as well as trackpad were completely uncontrollable. Upon this first experience I've got Apple support by phone and after a few try (opening in safe mood etc.) the problem was solved. Then I bought a MagicMouse in order to be on the safe side! Today the same thing happened again. I called the Apple team again. Right now I have been closing the FileVault as they recommended so and don't know if the same will occur again. I would be very glad having an advice by someone here experienced with the same problem. Thanks.

Dear Davis,
Thank you so much for this detailed, kind reply indeed. Let me give a short feedback.
* I managed to close the File Vault as the support team firstly advised by phone yesterday. It took 5-6 hours but shortened the opening time from 2,5 minutes to 1,5. When I bought my MacBookPro in 2013, it was opening within 10-15 seconds.
* I checked and performed all of the applicable steps those given by you except SafeMode test that was already tried a few days ago and yesterday morning too.
* Since yesterday evening there was nothing extraordinary with the trackpad & mouse usage.
* Just a few minutes ago the cursor suddenly started to tremble first horizontally then vertically by itself and highlighting some parts of the screen.
* I at once shut off the MagicMouse and try to have a handle on cursor through only trackpad.
* Right now it seems I am managing it...
But... I am not sure when will this irritating situation repeats itself. After sending this message, I'll try the mouse again.
Thanks a lot again,
Regards
