Open Terminal
You may have saved a file with the wrong extension, for example a JPEG file with a .psd extension. You cannot open the file in Photoshop due to an error
If you cannot remember the actual file type the file should be you can use the following method to determine the true file type of a document
Selecting File > Get Info... from the macOS Finder will not accurately tell you the true file type of a document as it only looks a the file name to make the determination. The method outlined below using the Terminal reads into the file header to get the true file type.
Open Terminal
In Terminal type "file " (the word 'file' with a space after it)
Drag the file you want to determine the file type of onto the Terminal window
The path to the file and its name will appear in the Terminal window
Hit the Return key to see the file type
In this case, the file is named "mydocument.psd" but the file is actually a JPEG. Rename the file to "mydocument.jpg" to open in Photoshop.
