I’m receiving occasional reports of PopClip freezing up when activating the Search action, and when using certain PopClip extensions. This affects version 2019.9 and 2019.9.1.
Thanks to a customer who emailed me at email@example.com and assisted with debugging, I am making progress with diagnosing the problem.1
I will continue to work on a fix, and I will update this blog post with more information.
Update, 29 Sep 2019: Another customer reported that deleting and reinstalling PopClip made the problem go away.
Update, 31 Oct 2019: The bug seems to be because PopClip is waiting for macOS to ask permission to automate the target. But macOS is not actually showing the permission request dialog. For the fix, I have attempted to mitigate this by calling the permission request on a background thread, to avoid locking up the app, and adding a timeout to abort waiting for permission if none is granted in a reasonable time. The fix is now in the latest beta version.
Here is a video showing the problem, thanks to my helpful customer (posted with permission):
