Mac: wait with upgrade to macOS Catalina
This post is over 5 years old, it may be out of date.
The brand new macOS Catalina is now available. It is **not** a good idea to upgrade with the first group of users, this will give problems. Up till now, we received reports about Adobe software not working, F-Secure Client Security not working, MestreNova not working, EndNote needing an upgrade to 9.3.1 or higher, Science VPNsec only working after reinstalling VPN. For more information what could go wrong, see Hold Off Catalina and Wait on Catalina. If the upgrade has already been done, the problems can be solved by installing an older version of macOS and restoring files with Time Machine.
