FWIW the 0.93.0.7 patch seems *more* unstable on OS X: instead of popups about BDM errors, it just crashes outright.
I'm glad the crash went away. The crash actually looked exactly like a last-minute bug that was fixed right before 0.93 came out.
Anyway, for various reasons, Armory remains unstable on some systems. On my system, Armory is stable. (That said, I haven't run the official 0.93.0.70 build yet.) On others, it's wonky. My suspicion is that it's due to Qt, a library we rely on. We are working on a possible solution in the background. It probably won't be ready for awhile yet but I do have hope that, after patiently waiting for so long, a reasonably stable OS X build will finally be out soon.
