Hi - wondering if anyone has any suggestions I have a MBP 17", late 2011 (the last model), running OS 10.10.2. Recently, occasionally the trackpad will stop responding to clicks - it goes down as normal, with an audible click, but the system doesn't respond. Cursor moves as normal, keyboard entries are unaffected. The only solution so far has been a restart, after which it works perfectly. Problem is arising maybe once a week - haven't logged it to be certain. Hoping one of you knowledgeable folk may be able to point me in the right direction.
