Not sure what else I can provide. I have SourceTree running most of the time while I'm developing, and I don't tend to shut it down, so it remains running in the background.
However, every week or so I might return to my computer after a period of inactivity and find SourceTree has crashed and my computer wanting to send a report to Apple - which of course I do (have been doing up until recently). Should I keep sending these reports to Apple? Does Apple do anything with them? Do they forward them to Atlassian?
