You took it weeks ago and now you need it. Here’s how to dig it out, from quickest to most thorough.
Sort your screenshot folder by date
Open the folder your screenshots save to (the Desktop by default), switch to List view with ⌘2 and click the Date Created column. If you remember roughly when you took it, scroll to that day.
Flip through with Quick Look
Select the first likely file and press Space. Use the arrow keys to move through the files while the preview stays open. It’s the fastest way through a pile of similar names.
Search by what’s in the picture
Spotlight can find text inside many images. Press ⌘Space and type a word you remember from the screenshot, like a company or a person’s name.
Make a Smart Folder of every screenshot
- In Finder choose File › New Smart Folder.
- Click + and set Kind is Image.
- Add another rule: Name contains
Screenshot. - Click Save and add it to the sidebar.
Ask Terminal
macOS tags screenshots with a hidden marker. This lists every one it knows about:
mdfind "kMDItemIsScreenCapture == 1"
The real fix: names you can search
All of these are workarounds for one problem: the names say nothing. When a screenshot is called “Lisbon Flight Booking”, typing “flight” in Spotlight finds it in a second. That’s what Snaptitle does for every new screenshot, on your Mac. See also Spotlight vs Finder search.
