Side note-there's actually a third option when you import images. So I keep my images in separate locations on my hard drive and don't actually put them into the catalog. Think of how much disk space your images take, specially if you work with RAW images.

The difference is that when you do the former-store images inside the catalog-the catalog can get really big. When you import images into CO you can either move them into the catalog itself or keep them in their original locations and just add a "pointer" into the catalog. Your catalog grows as you import and edit new images. (Sidebar, if you don't use layers you really should look into them.) (I say "basically" because CO does keep pre-rendered versions cached so it can update its UI quickly.) This "list of edit instructions" is kept in the CO catalog. When CO displays (prints, exports, etc.) an image it basically reapplies all of your edits to the image-crop, color, masks, etc., so that you can see all your edits. Remember, CO does non-destructive editing, meaning the source image file is not changed. Basically everything you do to an image in CO is stored in the catalog. Depending on your subscription/purchase option this may or may not be a free upgrade.Ī catalog is a file on your hard drive with a ".cocatalog" suffix. Have you already updated to Ventura? My guess is that you'd need to upgrade to 23. Looking at it appears that CO 22 cannot run on Ventura. Have you already upgraded to 23 and can't start 22 anymore so you can do a backup? I need to see what the best solution is there.ĭidn't see your note until I posted my response. Doing so makes the catalog *really* big and it will require a lot of space to backup. I *don't* use the option to save photos in the catalog. I keep my photos in separate locations on hard drive. A dialog appears before the app fully terminates, giving you the option to do a backup ("Backup") or just terminate ("Not Now".) The catalog backup is stored in a folder of your choosing.

The easiest way to do a backup is to launch 22 and then quit the app. I found the CO 23 installer by launching 22 and going to the Capture One 22 menu and selecting "Check for Updates.". When complete you'll have both CO 22 and CO 23 on your hard drive. You download the installer for 23 to your Mac and then install it as a new program. You don't actually "upgrade" CO 22 to 23.
