Google Earth Pro Crash
This is more of an answer. I installed the new FREE version of Google Earth Pro, but it kept crashing on my Late 2011 iMac. I found a 2013 Forum on Google Earth crashing and following their advice - which was to go to Library/Internet Plugins - I tracked it down to a 2010 fbplugin_1_0_1.plugin. Took that out and Google Earth Pro has loaded! Now to check to see if it holds.
iMac (27-inch Mid 2011), OS X Yosemite (10.10.2)
