Excerpt of article text...

In the last issue I posted about some complications I'd run into while upgrading to MacOS Catalina. I thought things had gone fairly smoothly, but after I'd written that article I ran into even more problems.

Some of the issues I encountered were with utility apps I'd written to help me automate various parts of the xDev publishing process. Since I only run those programs every other month when I publish a new issue of the magazine, I hadn't tried those projects under Catalina until I was finished with xDev 18.1.

Normally, I would have just moved some of those tasks to an older Mac running an earlier OS, but it just so happened that I simultaneously ran into a problem with Dropbox. Basically, it stopped syncing on my old Mac so I didn't have access to the latest magazine files which were on my Catalina Mac.

I ended up having to use sneakernet to move files between computers via a thumb drive, so the whole process was uncomfortable and frustrating. Since publishing the magazine is the final step in producing it, this was all last-minute and I was in a time-crunch. That's not the best time to find bugs in your workflow!
