I have TotalSpaces 2 under macOS Sierra 10.12.1 & 10.12.2 just randomly crash without a message. It just goes away from the menu bar (no crash dialogue).When I manually restart it, it knows the geometry, exposure and Desktop of every application including the current workspace, a very minor annoyance.
I will look for logs next time it happens. It happens once or twice a week and I am on my iMac a good 10 hours a day.
I so hope Apple does something so we do not loose TotalSpaces 2 (or later) so you can functionally run without the SIP modifications that are "unsupported". I wish Apple was responsive to their Mac developers and users but we are becoming less and less important to them and their bottom line. Who would have thought that a cellphone OS would be more important to them?
