So what's the solution here? Buy a new monitor if we want to use up-to-date versions of macOS? Anyone who uses Apple's FCPX or Logic knows we'll have to update to Mojave because eventually we'll try to open the latest version of said software and be told "You must be running Mojave to open this" I'd really ditch Apple because of stunts like this, but I really love Logic and FCPX so I'm stuck with it.
