Froze in the middle of installing Yosemite. Do I force quit?
My computer froze in the middle of installing Yosemite.
what hat should I do? Force quit?
iMac (21.5-inch Mid 2011), OS X Mavericks (10.9.5)
If your iMac is frozen, close the installer or restart your Mac and see if OS X can start up properly. If not, you will have to reinstall OS X through OS X Recovery -> http://support.apple.com/kb/HT4718
