CCleaner Won't Launch in CCleaner for Mac Posted November 16, 2012 Is this what I have. Running 10.8.1 and using CCleaner since the 10.8.1 version came out. Can think of nothing I did then now "CCleaner Quits Unexpectededly" on launch. Uninstalled and deleted and reinstalled and same thing. Nothing I can do will get it to work?
