Rooty: Thanks for the feedback. I think I will fully investigate FTM and make the leap if we are stuck "in limbo" with RM.
You could always try RM7 under the full version of CrossOver. I’ve been running that for several years and it is absolutely rock solid for me with the current highest versions of everything. I do not use the Ancestry function but am a very heavy user of the Family Search interface. I just leave RM running for days, with my iMac sleeping when I’m not using it. When I switch to RM, it just continues and any use of FS just continues from where it was. No need to re-login or anything like that. I’m not sure when I last had to kill (force shut) RM, but it has moved over the years from not that infrequently to very very infrequently.
Yes, Crossover costs money, but worth the pleasure I get out of the genealogy hunt.
PS Yes, it is still a 32bit application in Mac terms, so won’t run on Catalina as is. One has to assume that they will fix that or they will no longer have a Mac market. So, if you were to go that way, there would be an interesting race between a Crossover update, RM8, and your possible desire to get on to Catalina. You have to decide whether an interim extra cost is a price worth paying.
