MPG Recommendation on macOS Mojave
Given last year’s surge of very serious security bugs with macOS High Sierra, MPG recommends waiting at least 6 months to migrate to macOS Mojave.
There isn’t anything worthwhile for “upgrading” to—and software may break.
In particular, older programs I rely on (such as accounting) might not work at all, which would be a $500 cost to upgrade. I’m in no hurry to find out!
