Same probleme here with my three month old MacBook Pro 15". The malfunction started last sunday. Single click is recognized as right click (two fingers), cursor hangs etc.
Reboot sometimes helps for few hours, sometimes for few minutes. I'm not sure but I think the only update I did on sunday was iTunes update otherwise all updates are installed on my system. I called customer Care twice today. With the first supporter we did hold Shift-Ctrl-Alt, power on button, 10 seconds waiting. Then restart and hold (can't remember) Shift - alt - r (??) and power on again. After that trackpad runs normal for three hours. Then same issue. I called Apple support again and did following:
- Starting in safe mode (all normal)
- cleaning library/cache folder
- delete universalaccess.plist / systempreferences.plist
- restart
- after two minutes trackpad issue 🙂
- supporter was frustated
- creating new user account and logging in with new user
- no problems
- going back to my main user, no problems
- working 4 hours without problems
- leave office / eat something at home
- starting up MacBook, after two minutes trackpad issue
- restart all works fine now since 30minutes
Is this a Software or Hardware issue??? I'm not keen to send my MacBook for service or drive several miles to the next Apple Store when it is "just" a software problem.
Hope anyone have an answer for this problem. Thank you and sorry for my bad english.
