Two minutes, one time.
Your download is starting. macOS is strict with apps from outside the App Store, so the first launch takes three extra clicks — this page walks you through every screen you're about to see. After today it opens like any other app.
Open the .dmg, drag MASTERY into Applications
The window that opens shows you exactly this — drag the left icon onto the right one.
Open MASTERY — a warning pops up. Press Done.
macOS says it "could not verify" the app. That's because MASTERY isn't registered with Apple yet — not because anything is wrong. Do NOT press "Move to Trash."
System Settings → Privacy & Security → "Open Anyway"
Open System Settings (Apple menu, top-left of your screen), click Privacy & Security in the sidebar, then scroll down. You'll find this waiting for you:
Press Open Anyway, confirm (it may ask for your password or Touch ID) — and MASTERY opens. That's the last time your Mac will ever ask.
Make it yours
MASTERY boots, greets you, and asks two things: your name and your state. Pick your state and your question bank loads that state's insurance law automatically. Then start a drill.
Didn't work? The guaranteed fallback
If there's no "Open Anyway" button, or macOS claims the app "is damaged": open Terminal (press ⌘-Space, type "Terminal", hit return), paste this line, press return, then open MASTERY again.
xattr -cr /Applications/MASTERY.app
Why all this? Apple charges developers $99/year to sign apps so they open without warnings. MASTERY is young and free — until it's signed, macOS shows one scary-looking (but harmless) hurdle on first launch. Windows users see a similar SmartScreen notice.
