Interesting link, Allen. It definitely has some issues I would be concerned about. The Font issue is definitely troublesome. Also, I see where that article recommend visiting the site
https://roaringapps.com/, which is the "top" of the roaring apps site I have mentioned numerous times:
https://roaringapps.com/apps. It always amazes why folks are in such a "rush" to install the version of a new Mac OS, yet incompatibilities exist with third party applications. Heck, I have read on Micromat's site about folks trying to use Tech Tool Pro with Mojave, even though Micromat definitively states that the current version is not compatible with Mojave.
Since leaving the newspaper and graphics business, the font issue kinda flew under my radar. Having a lengthy background in graphic arts, I'd become something of a font hog over the years. At one time, I had in excess of 3,000 typefaces available. These days, I suppose I can get by with the generous smattering Apple supplies.
I got curious about it and opened a few really old documents and found that some of my really old TrueType fonts didn't display quite right, but they printed okay. Some of my old Type 1 Postscript fonts also displayed fuzzy and they also printed fine. However, I found a number of both TrueType and Postscript fonts that went absolutely bonkers when printed out. Individual letters were missing, some printed several points above or below the baseline. The most trouble seemed to be with printing fonts that were on a path. I got some real Twilight Zone results there!
I'd noticed, too, that you posted something about OpenOffice and Mojave. I hold Microsoft in the same high regard as I do Adobe (don't let the sarcasm there drip all over your keyboard there). I have to say those Apache fellows have really done outstanding work in providing an Open Source alternative to MS Office. The few instances in which there were any issues, I suspect those boys and girls must've called in reinforcements from a couple of other tribes in getting everything fixed.
(I hope nobody goes all PC about that. Excuse me for having a sense of humor. Lighten up if you do and focus your attentions on things that really do matter.)
OpenOffice behaves nicely with Mojave for me. I haven't checked for any updates lately, so perhaps I should just to cover my butt.
You and Cory and a couple of other guys here offer a wealth of information and helpful directions, and I'm reluctant to stick my nose into anything because I don't consider myself to be an authority or a guru. But I do hope I can sometimes bring a little something to the table. I almost never notice anything referencing sources connected to OWC, and that's where I get info I don't easily or quickly find here. And I swear, I'm NOT an employee or agent for OWC as much as it might seem so since I'm constantly blowing their horn. It's just that I've been a customer of theirs for years on a commercial as well as personal basis, and I've never had a better experience with anyone else since I began doing business with them back in the early 1990s.
