Ever since I upgraded to OS X Mojave I have encountered a few issues with various software on my iMac. I'm aware many of the problems involve compatibility (32bit-64bit thing), but according to my system report Photoshop CS6 is compatible. However, I seem to get the following error messages when working on some files - Could not update smart object files because of a program error - or - Could not update smart object files because an unexpected end-of-file was encountered. I've never encountered these errors before, so it seems too coincidental that they appear now since upgrading my OS X. Is there a solution or some fix I can use?
