R warnings "IMKClient Stall detected"

Question

I get the following warnings in R since I upgraded to a new MBP. Alerts appear when I launch the application and reappear at odd intervals.

There seems to be little to no information about this other than this unanswered threat . Any help would be appreciated.

Answer 1

I have this error while running my own code. it appears when I run the automatically generated applescript and then execute it. I suspect that this happens when the interface of any program that you use hangs, probably because the developer did not write the background processes of the program in question to work on another thread.

as far as I can tell with this, it does not seem to violate anything very much, so I will simply ignore it. if this really bothers you, you can start updating your most used programs and see if this is fixed.
