Hi all! I have an annoying problem. A couple of days ago I happened to start an old version of VMWare Fusion on my MacBook Pro, running macOS Mojave 10.14.2. This corupted all file permissions on my computer. This has now been resolved, BUT I cannot login to iTunes, App Store or iCloud. When I enter my email address and password, I get prompted with an error message saying "This action could not be completed. Please try again", no matter what I do. I have tried: 1) Resetting my Apple-ID password 2) Running Disk Utility First Aid and other diagnostics - all of which says everything is OK on my system 3) Logging in using my Apple-ID on my other devices. No problems there. It works just fine on other computers, iPhones etc. 4) Updating to 10.14.4 (somehow I'm sometimes logged in after reboot to be able to do that). 5) Try to download a free app from App Store - that gives me an "Unknown Error" message. 6) Creating a new Apple ID and login using that account (which works) and then log out again. I have not tried to make a clean install and then put all my files and accounts back again using Time Machine. My main problem is that I do not have a recent backup from before the crash. The last backup is from November last year. Bad. I know... I think this might be an error in the Keychain app - but what can I do to fix it? Extensive Googling and searching MacRumors forums comes up empty. Please help!
