imovie won't export
When trying to export an imovie, it fails stating "The operation couldn’t be completed. (com.apple.Compressor.CompressorKit.ErrorDomain error -1.)"
I checked every file to make sure nothing was corrupted and ensured that all of the content I was using was fully uploaded. I talked to an online chat support and they told me to shut the computer down and reboot in safe mode pressing and holding the left shift button for 40 seconds. That it should now be able to export. But to no avail, instead I got the message "Safe mode not supported, does not support OpenGL hardware acceleration, which is required to run imovie. Please reboot normally and try again." I tried rebooting normally and the same error from before error-1 prevents the export.
Please if anyone has run into this issue or knows what to try, please let me know! I'm struggling to get back onto apple support chat.
