Updating virus definitions and program version do not work anymore since updating from OS X El Capitan (10.11.6) to macOS Sierra 10.12.
I’m using Avast Mac Security 2015, version 11.17 (46792) on macOS Sierra 10.12.
When trying to update virus definitions or program version manually, the following error messages appear:
“Authorization failed. You don’t have permission to save the file “501” in the folder ‘elevation’.”
And after that: “Communication with Avast service failed. The operation couldn’t be completed. No such process.”
Any help would be appreciated.
Update: the automatic update process of updating virus definitions in the background still seems to work though. Only manual updates (by using the program interface) are broken.
OS X 10.12 deletes some of our files on upgrade (the latest beta did not do this…). We are working on a fix/workaround which will be released ASAP as an program update.
