BUG REPORT. AE fails to overwrite Files that are selected in the OS. EVERY VERSION SINCE THE ADVENT OF OS X
this isn't and Idea, it is a report of a show stopping, LONG TERM bug that YOU HAVE YET TO FIX.
when rendering out of Aftereffects, over top of an existing file, the render fails, if the file is simply selected (and sometimes just visible) in the finder. and then from that point on, AE cannot render the file if the user does not first delete the file by hand.
this BUG is at least 10 years old. It is not 1995, there is no need for this obscene punch in the gut. Time to get on it.
mac os X (every version.)
AE (every version.)
expected behavior: steam roll the old file regardless of it's status in the finder, without complaint.
steps to duplicate issue:
render an animation.
go to the finder, select the resulting file,
go back to AE and serenader the same file, choosing to overwrite it.

I want you to know, this is a VERY old bug. It has been widely reported to adobe, and independently verified so many times that you really shouldn't need convincing. I have been reporting it on and off to adobe as a bug for 20 years.
what it boils down to is that After Effects was never updated to handle situations where OS X generates _any_ kind of preview for a video file. AE thinks the file is open, and crashes the render.
OS X is routinely updated to do more live previewing, all the time. Sooner or later, the only files you will be able to render over top of are the file formats that no one uses.
Thank you for reporting this issue, and for your patience. We are not able to reproduce the issue in the latest version of After Effects. Is this is still occurring for you? If so, would you be able to demonstrate it in a screen recording? This would help us to reproduce the problem on our end so that we can diagnose what is going on.
Thanks very much for any additional info,
