When it comes to upgrading a an operating system, specifically if you’re on a Mac of any sort, people have mixed feelings. I’ve heard some people say they’ve lost a day’s worth of productivity. I’ve heard others say that the upgrade worked flawlessly.
With two very minor hiccups, the upgrade to Mojave has been in the latter camp. Specifically, at the time of this writing, Firefox doesn’t mainly play well with writing to the filesystem via its standard dialog. And my installed of Git was hosed.
