open files in photoshop instead of preview.

Select an image file, press command +i which opens the Get Info window, Choose Photoshop from the "Open with:" menu. Then click the "Change All…" button.

I keep setting sonoma to open image files in photoshop but they all seem to open in preview

Preview cannot open .PSD files. (this is sort what you have said here - unless you are trying to open all JPG (for instance) in Photoshop - which wouldn't be advisable)

Right click a PSD (or target image format) file to see what the "Open With" disclosure menu says is the default - report back with a screenshot.

THEN try rightclick/Get Info and Change All to match your default destination for each file type.

Most file types should be set to open with Preview.

PSD should be all set to open in Photoshop.

Also make sure you have a correctly installed licensed version of Photoshop. You might need to reinstall it. Can you open your target image from within a running Photoshop?

If at any time you want to open a non-PSD image files in PS - just use right click to choose an alternative program to open it from.... see screenshot.

FWIW, my guess is you need to rebuild Launch Services. Unfortunately I don't know how to do that in Sonoma. There is an app, OnyX that can rebuild Launch Services. You need to be very careful when using such a utility. If you wish to try it, I would suggest you uncheck everything in the Maintenance tab other than Verifying and Launch Services database under Rebuilding.

One can boot the Mac in Safe Boot Mode. Part of that process will rebuild the Launch Services database. Although I have shell scripts to force this manually, I consider it more practical to let the operating system do it via that boot method.

You can do this from the command line:

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -seed

It's a safe command. I recommend quitting all apps before running it and then restarting afterwards.

Are all the image files you are attempting to open in PS the same or different file type (.jpg, .png, .dng, for example)?

If different you'll have to set the instruction to open in PS for each unique file type.

I didn't realize you were talking to me. lol I was going to mention Safe Mode but I didn't know if that rebuilt launch services or not.

Older Safe mode documentation used to mention it but Apple continues to remove stuff from newer articles. Etresoft has since posted the command-line solution that I had abstained from posting.

I stand corrected! I haven't been paying attention - this is a feature that must have been added somewhere along the line, as it didn't used to be the case. In any event I was just trying to discern what intent the OP has - (change all images to open in PS by default doesn't seem to make sense) and to make sure there's a working version of PS installed.

By default, screenshots are in the PNG format.

Understandable. Unfortunately I don't know of any other reason for your issue seeing Launch Services determines which apps launch what. Maybe someone else will have an idea.

FWIW, the user has only tried JPGs. PSD files were never mentioned.
