Hi @jrwren! Honestly, I never try to make it running on macOS, perhaps because my main goal to run and debug it on Linux platform first. I hope finally do this, but do not promise that in nearest days. Thanks for reporting this issue, will think how to solve this problem.

[thepaul]

I haven't tried go-rsync, but I think I've been able to work around this problem in gotk3 by calling runtime.LockOSThread() in the main goroutine (the one that calls gtk.Init() and other gtk calls later). As long as the calls all come from the same OS thread, macOS seems happy.
