For some time now (perhaps since the 10.13.3 upgrade of MacOS) I have been waking my Mac up from sleep and seeing between 3 and 7 cascading dialogue boxes with the error message:
"Unable to find an application to open URL
rstf://?scheduleState=1, with "Ok, Cancel, Find Application" buttons.
I have searched everywhere and cannot find any reference to rstf or scheduleState (there some scheduleState stuff, but it seems unrelated).
Does anyone know how I can find and kill what is trying to open this URL?
Presumably the job is scheduled somewhere, but crontab just has a SuperDuper entry and I've since deleted SuperDuper.
