Hi community,

I use a Mac - MacOS Ventura, have CC using PS but now I always get the message 'scratch disk is full', and there's only one disk on the display. PS will not open, then how can I add another volume like a external hard drive of 1Tb?? Using de 'command' button whilst opening PS doesn't work either. It used to work, until the update. Doen anyone has another way to get it working?

Thanks in advance.

Carine.

Hi @wobke362

I would like to know if the steps above helped resolve the issue, or do you still need assistance? If you found something that worked, it would be great if you could share it, as it may also help others facing the same problem. I look forward to your response.

Hi @wobke362 could you share your computer info, ie Make/Model, how much RAM/HD, etc?

If you go to your HD and get file info, how much space do you show as available? Any screenshots or other visuals could help us see what might be a solution.

Thanks,

I don't understand why I have 70Gb system data??? I can't get into that system.

Don't know how it is formatted and don't think I can get more free space... My Mac has 'only' a 125Gb space.

Please go to the Help menu in Photoshop, then System Info. Copy and paste the contents of that report here.

If you then open System Information in the computer Utilities folder (inside Applications), there is a section titled Storage that shows each of your drives. If you click on one it shows File System. If its NTFS or ExFAT, you would need to reformat it for Mac to use as a scratch disk.
