The first time it opens

Designer opens to sign-in: use your Fireball account, and your projects library is there.

If something's off

macOS says it can't check the app for malicious software.
That only happens with a copy that didn't come from this page. Delete it and download again from here.
How do I update?
Fireball Designer checks by itself and installs updates when you quit it. To check now, use the app menu ▸ Check for Updates.
How do I remove it?
Quit it, then drag Fireball Designer from Applications to the Trash.
