P: Doesn't save files to external drive formatted for ExFat - macOS 10.15 Catalina

I'll give it a try.  I have simply been saving a new to my desktop, then, moving the file over to my external.  That has been working, too, although a little cumbersome.

Hi,
I think i have a temporary solution that has been tested for a week and works fine.
The first save of a psd file is done on the local hard disk.
Then i copied the psd to the external hard disk and continued saving the changes on the external hard disk without any problems.

Same issue! I can't save any files in Photoshop 2019 now that I've updated to Catalina! Help!

Same issue here. Photoshop CC 2020 and CC 2019. Sometimes it works, sometimes not (stops saving and when I force quit PS, file is broken) 😕😕

For what it's worth I was using the latest versions of photoshop and indesign with no problem.  I only just got round to updating to the latest mac OS and now have the issue with both Photoshop and Indesign - with indesign crashing when I export a JPG file and working off a SSD USB drive.  Working on the local drive seems to work for now.

Not sure about that yet... but I am here to report that since I have been saving to my desktop ONLY, I have had no crashes within Photoshop 2020.  That's 2 two hours without a crash....

Another workaround while we continue to work on getting this issue resolved is to use an external drive that isn't exFAT formatted.

Like so many others, it's Russian roulette.  Some saves work, and for me, it'll freeze at 0%.  Once frozen, you can click around in the program, but you can't save — or on any other work being done within Photoshop.  Force Quit and you can't reopen — have to bomb the Mac.  I am trying to be mindful to save all files to my desktop and then overwrite on my removable drive...  So far, so good.
