I'm running Mac OS X Sierra which is of course a beta, so the openspin/bstc crash can come from here, I don't have the log yet about the crash, but after loading a .spin file, and try to use any command that will compile it, I get a "Process crashed" error dialog, and as soon the dialog is dismissed the IDE become unresponsive (beach-balling).
The crash is not related, even if it would need to be investigated to understand what failed, but the IDE should recover from that crash and not stop answering to user input.
I will try to get logs to see if there is anything interesting
