I'm as anxious as anyone for the '19 version on Mac, but I'd rather endure the wait than get a buggy release. I'm running the beta of the new Mac OS on my other computer, and it's been unusually glitchy - and I've been in the beta program for a number of years. I can't recall a prior release that caused as many conflicts and odd quirks as this one.

Unrelated to BIAB, but I'm running the new iOs beta on my phone as well, and it's a train wreck so far. First time I've ever regretted upgrading early.
