Installing theoremEd on a Mac
About a minute, and you drag one icon.
- Open the download. It is called theoremEd-….dmg: click it in Chrome's downloads (top right) or in your Downloads folder. A window appears with the theoremEd icon on the left and an Applications folder on the right.
- Drag theoremEd onto the Applications folder. That is the install.
- Open Applications and double-click theoremEd. macOS asks once whether you are sure, because you downloaded it. Click Open.
- Choose Start free. Bought a plan? Choose I have a code from theoremed.com and paste your code instead.
- Choose how it reads your work. Read it for me opens System Settings (if macOS asks first, click Open System Settings): switch theoremEd on in the Screen Recording list (newer Macs call it Screen & System Audio Recording), and type your Mac password if it asks. theoremEd restarts itself, once. Or choose I'll take the picture: no permission, you drag a box round each problem.
Then pull up a math problem, press Control–Option–T to open theoremEd, and press Look at screen. theoremEd lives in the menu bar at the top of the screen (the ƒ icon), not in the Dock; click it there to open it too.
Updating
When there is a new version, theoremEd says so in its panel. Click Update: it downloads it, swaps it in and reopens by itself in about a minute. Your code, your streak and the screen permission all stay.
If the button says Download instead (version 1.13.0 or older), it only fetches the file. Quit theoremEd first (ƒ in the menu bar › Quit theoremEd; a Mac can't replace an app that is open), then open the download, drag theoremEd onto Applications and choose Replace. You do this once: after that, Update does it all.
About that “are you sure” box
macOS shows it once for anything you downloaded, including apps from the App Store's competitors and every Mac app that is not from the App Store. Click Open and it never appears again.
What you should not see is “the developer cannot be verified”. theoremEd is signed with an Apple Developer ID and notarized by Apple — Apple scanned it for malware and found none — and the disk image carries that proof inside it, so your Mac can check it without even being online. If you ever do see that message, tell me, because it means something is wrong on my end.
Or use the Chrome extension instead. It installs from the Chrome Web Store, there is no file at all, and it does the same thing in your browser tab.
What it needs
macOS 12 Monterey or newer, Apple Silicon or Intel. It reads any window on the computer rather than only a browser tab, which is the reason to use the Mac app over the extension.
Nothing to sign up for
No account, no card, no code to type. You get 30 messages to start and 10 a week after that, and every feature is included — graphing, quizzes, practice sheets and the whole Basics reference.
