Issue: Stuck job in Apple’s Compressor app.

Resolution: Remove the historical jobs in your local home folder.

~/Library/Application Support/Compressor/History/V4

Note: to get to your home folder hold down the OPTION key and select the Go menu in the Finder.

Compressor is the best sidekick to Apple’s Final Cut Pro X and it gets used a lot. But occasionally something goes awry. It’s software running on a computer. So we troubleshoot. What looked like a stuck running job was mostly leftover evidence of an old job. The Apple support document I found didn’t mention this tip but instead talked about zipping up your settings folder which has all your custom compressor settings for things like YouTube outputs or anything custom. Didn’t seem useful to me to remove but this historical stuff, don’t need it and POOF this solved the issues. It’s not always this easy but something you just take the win and go with it.
