Install on macOS

SolarLayout for macOS is signed and notarized by Apple, so the first launch should open without any "this app cannot be opened" warnings.

Download the macOS installer.

Picking Apple Silicon or Intel

• Apple Silicon — any Mac with M1, M2, M3, or M4 chip (2020 onward). Most Macs sold in the last few years.
• Intel — Macs built before late 2020 with an Intel processor.

If you're not sure: click the Apple menu in the top-left of your screen, then "About This Mac". The "Chip" line tells you which.

Install steps

1. Download the .dmg for your architecture from the download page.
2. Double-click the .dmg. macOS mounts it as a virtual disk.
3. Drag the SolarLayout icon into the Applications folder shortcut.
4. Eject the .dmg (right-click → Eject) and delete it from Downloads — the app is now in Applications.
5. Open SolarLayout from Launchpad or your Applications folder.

First launch

Because SolarLayout is notarized, macOS lets it launch directly. You'll see SolarLayout's sign-in screen on first launch — click Sign in (or Create account), finish in your browser, and the app picks up automatically. See Signing in for the step-by-step.

If you see "SolarLayout cannot be opened because the developer cannot be verified", you have an older or unsigned build. Re-download from the official download page above.

Updates

SolarLayout checks for updates on launch and offers a one-click "Restart to update" banner when a new release is available. There is no separate updater app.

Uninstall

Drag SolarLayout.app from Applications to the Trash. Your sign-in lives in ~/Library/Application Support/SolarLayout/credentials — delete that folder if you also want to remove the saved sign-in.
