Change the File Extension

- Right-click on the problematic file and select Properties.
- Check the type of file.
- Then right-click on the file again, and select Rename.
- Delete the false PSD extension. Change the file extension to the correct extension.
- Check if Photoshop can now open the file.
Check File Extension Type on Mac
Select your file, and click on the File menu. Then click on Get Info. Locate the Name & Extension section, and click on the arrow to expand the section.
If you want to show the extensions for all of your files, launch Finder, and click on Preferences. Then go to the Advanced tab and tick the “Show all filename extensions” checkbox.
Then change the extension to the right extension type. By the way, many macOS users confirmed that changing the extension to .tiff allowed them to open their files with all the layers intact.
