That didn't work. But thanks.

As stated, I'm not an IT expert. So since commands need to be executed EXACTLY, I would need to know if I hit "return", quit terminal app, or any specifics.

Can't believe how difficult it is to make an obvious UI improvment. Who needs PNG? Can't send to a PC user. Takes up space. JPG far superior.

I had already tried

defaults write com.apple.screencapture type jpg

What about this string?

killall SystemUIServer

Your original line of code posted had 'jpg' in the string- no quotes here, see the above.

killall can be used instead of a restart. If the killall does not work try a restart to see if the command "took."

Yes enter your command and hit the return key if it does not run immediately, and will put you back out at the prompt; no harm here hitting the return key.

Yes if you are done with the terminal.app you can quite the terminal application.

I just ran this command on Mavericks 10.9.3 and I successfully changed screenshots to jpg and back to png.

addendum: Windows can read png files, there can be some issues- google for more information.

this did not work for me 😟

I don't get any errors but the extension also isnt changed

tried logging in and out, restarting my laptop, etc. but nothing changes 😟

Same problem here! And I am an IT-Expert!

defaults read com.apple.screencapture type

shows me "jpg" but everytime I use Screencapture it will suggest f*** .tiff instead of jpg.

I also tried restart and also tried png instead of jpg. Always the same!

I am using MBA with OS X 10.9.4 (german)

Doing

defaults write com.apple.screencapture type "jpg"

works for me. It writes the setting to

~/Library/Preferences/com.apple.screencapture.plist

and therefore only applies to a single user account. I did not have to logout/in or reboot or do killall it took effect immediately. The defaults command is integrated in to the operating system such that changes to preferences made by it are automatically reloaded, other methods of editing plist files do not have this advantage. This was tested with Command-Shift-4 in OS X 10.9.4 on a MacBook Pro. The 'Grab' utility however does not use this setting.

Doing. This really only seems to work for shortcut Command-Shift-4 and NOT for the grab utility (Screenshot, Bildschirmfoto). That's bad!

See http://superuser.com/questions/163195/save-os-x-grab-images-in-formats-other-tha n-tiff

yes (lol there is not angry emoticon thanks apple) who even uses .tiff?!
