Random freeze using trackpad (10.10.2)
I have a brand new (<2 mos. old) 15” MBPro Retina which I just updated last night to 10.10.2. Doesn’t matter how many or few apps or Safari tabs I have open, nor whether I’m using Mail or Safari. After about an hour (sometimes less) while I am moving the cursor using the trackpad. the cursor freezes and EVERYTHING but cmd-opt-esc becomes unresponsive. Cursor remains either the I-beam or hand, can’t drag windows, close tabs, drop down menus, click on a button, etc. All that responds is doing cmd-opt-esc, hitting enter for each app to close (clicking on the actual blue button does nothing--it doesn’t click). When I finally reach Finder and hit Enter to Relaunch it, the screen simply refreshes and I have to hit the Power key to shut down (and hit Enter because none of the buttons in the dialog box will respond). Then once the computer shuts down I have to start it back up again. Note that I cannot simply bring down the Apple menu and click on Restart or Shut Down; once I boot back up I am there is neither a “It appears your computer was not properly shut down” message box with an option to see details, nor a dialog box asking for if I want to report the problem to Apple. And I am familiar with kernel panics since the dawn of OS X--this doesn’t look like one, since there isn’t code splashed all over the screen.
Is the problem my trackpad, in which case I need to switch to a mouse until I can get the computer repaired under AppleCare; or is it the 10.10.2 update, in which case do I need to uninstall it (and how do I do that?) or wait for a patch to be issued?
