I have the same problem using MacOS 10.14.6 Mojave. Upgrading OS is not an option for me because I need to run legacy 32-bit applications. The problem began when FortiClient 7 updated automatically. This shouldn't happen, if the new version is not compatible with my system it should not update. Yesterday I deleted and reinstalled it. Current version is 7.0.5.0166. Can I revert to the older version? Where can I get it?
