Running Lightroom Classic 10.0 on macOS Catalina 10.15.7 (8 GB RAM, 3,5 GHz Quad-Core Intel Core i5) I regularly get my iMac freezing and rebooting itself while exporting an edited from RAW to JPG. Apparently this happends when I perform an other task when exporting (e.g. opening a browser, moving files on the desktop)
Here below is the error message generated automatically and sent to Apple. I believe this is an Adobe problem as all other programs work properly.
Thanks

So you have 3rd party plugins? If yes, try disabling them and then export again. What is the file size that you are exporting? Does it happen every time you export a raw file as a jpg?

It often happens while I export a file but this is not systematic. I tried to replicate the incident but without much luck. In any case it only happens when I use Lightroom and this must have happend around 20 times over the last three days.
It has never happened with earlier versions from Lightroom and no changes have been made to this Mac since I updated Lightroom classic.
Fans and cooling are working well (ad suggested on this forum).

Computer freezing and restarting during Export is usually a sign of the CPU overheating due to a failure of the cooling system somewhere. You need to check this. Also make sure that all air vents are not blocked, all fans are working, etc.
