Con cleanmymac ho cancellato i file di lingua, safari, mail...non si aprono

Well, the main point is - that CleanMyMac Classic outdated version ( like 1.9.x) is not compatible with Mac OS X 10.9 or 10.10.
Please make sure that you're running the latest version of CleanMyMac 2 which you can download from our website. :)

Or even better, be sure not to install or run CleanMyMac at all on your Macs. So our readers will be 100% sure to be free from any issues. :)
