I wrote a tip to disable screenshot shadows for macOS High Sierra using Terminal. But macOS Mojave changed the way we take screenshots, and the old commands no longer worked. But thanks to The Mac Observer reader Severisth, we now have the new commands to disable Mojave screenshot shadows.
Disable Mojave Screenshot Shadows
As with the old commands, all you have to do is copy each command one at a time in Terminal, then press Enter.
defaults write com.apple.screencapture disable-shadow -bool true
And we’re done!
