Screenshot area to clipboard (Control + Command + Shift + 4) doesn't work
Things to check...
- The receiving app can accept the format, .png by default.
- The buffer hasn't been replaced with other content, text etc.
- If Cmd ⌘ Ctrl ⌃ Shift ⇧ 3 would work to capture the entire screen to clipboard.
- That the key commands are on & set to defaults in System Prefs > Keyboard > Shortcuts > Screen Shots & also that resetting to defaults doesn't generate an orange warning triangle that another shortcut is using the same key command.
If it’s a MacBook Pro with touchbar make sure the camera icon is not in the touchbar
If it's a MacBook Pro with touchbar, look at the touchbar. You should see three options:
- Selected Portion
- Window
- Entire Screen
Select the first option and that will start being your new default.
In my case, it turned out be Quicksilver and specifically the 'clipboard plugin' in Quicksilver that was causing the problem for some reason.
As soon as I disabled the shortcut to paste from the clipboard for cmd-ctrl-shift-4 (and 3), then it started working again!
