Hi guys, Avast 11.5 turned my OS X El Capitan usage into a nightmarish experience. Ever since I updated to El Capitan and installed Avast 11.5 I have not been able to login to iCloud in my OS. After countless hours spent lurking the Apple forums I decided to try other users’ advice and disable the antivirus. This finally resolved the issue, after ~3 months of slow boiling rage.
Would be a nice thing if you fixed your broken product. >:(
