Fixes for the most common problems. Still stuck? Email hello@screenmac.app with your macOS version and what you expected to happen.
Captures come out blank or the app asks for permission
Open System Settings, then Privacy & Security, then Screen & System Audio Recording. Turn on Screenmac, then quit and reopen it. macOS only applies the change after a relaunch.
A shortcut does nothing
Another app or macOS may already use it. The built-in screenshot shortcuts can be turned off in System Settings, then Keyboard, then Keyboard Shortcuts, then Screenshots. Or pick different keys in Screenmac's settings.
Copy doesn't work in the browser editor
Some browsers block writing images to the clipboard, or only allow it on HTTPS. The editor tells you when that happens. Use Export PNG instead; it works everywhere.
My own image won't open in the editor
The editor opens PNG, JPEG, WebP, and GIF files. Very large images are scaled down to 6000 pixels on the long edge so the browser stays responsive.
