Hey everyone! A bit of an unusual announcement this time but we thought it was important to let you guys know about this. After the recent macOS Big Sur 11.5 update (released July 21, 2021), we’ve received a few reports from users having trouble opening files saved to their external drives. Right now, saving a PXD document to an external drive makes it lose its pixel information, while regular image files, like JPEG or PNG, fail to open completely. Our testing has shown that these issues are exclusive to the drives that use the ExFAT file system format. We have also noticed the same behavior on macOS Monterey 12 Beta.

We’ve notified Apple about this regression and are waiting for a solution at this time. In case of any updates — we'll post them in this thread. In the meantime, here are a couple of workarounds you can use to save files without them getting damaged:

1) Reformat your external drive to the macOS-native Mac OS Extended file system format. See Erase and reformat a storage device in Disk Utility on Mac to learn how.
Important: For this workaround, make sure to backup files from your external drive first!

2) Roll back your macOS to the previous version — macOS Big Sur 11.4. You can use Time Machine for this.

If you come across any other solutions, feel free to share them below!

One more workaround suggested by one of you guys — export files or save the PXD documents to Desktop first, then move them to the external drive. Seems to do the trick!

I just tried your last suggestion and it worked. I suppose we will have to wait for the next Big Sur update to see if they fix this problem.

Fingers crossed it'll have a fix.
