Install on macOS

Requirements

• macOS 12 (Monterey) or newer
• Apple Silicon (M1/M2/M3) or Intel x64
• 4 GB RAM minimum, 8 GB recommended
• 500 MB disk space
• Metal-compatible GPU (all Macs from 2017)

Installation steps

1. Download the installer: diazatlas.com/download — pick the .dmg for your chip (Apple Silicon or Intel)
2. Double-click the .dmg file to open
3. Drag Diaz Editor.app to the Applications folder
4. Eject the .dmg (right-click → Eject)
5. Open Applications → Diaz Editor (first time with right-click → Open, otherwise Gatekeeper blocks — see below)

Gatekeeper warning on first launch

macOS shows: "Diaz Editor.app can't be opened because the developer cannot be verified."

This happens because we're not (yet) notarized with Apple. Notarization fee + Developer ID costs $99/yr — coming in roadmap Q3 2026. Until then: 2 workarounds.

Method 1 — right-click (fastest)

1. In Applications: right-click Diaz Editor
2. Click Open
3. Confirm Open in the warning dialog
4. One-time only — future launches work normally (double-click)

Method 2 — terminal one-liner

For tech-savvy users — remove the quarantine flag in 1 command:

xattr -dr com.apple.quarantine /Applications/Diaz\ Editor.app

After this the app opens normally via double-click.

First launch

First launch shows the trial-activation dialog (same as Windows). Enter email + name + phone. 14-day trial, all features. After that, paste your license key via menu → License.

Troubleshooting

App crashes on startup on Apple Silicon

Possibly wrong build downloaded (Intel build on M1/M2/M3). Check via Finder → right-click Diaz Editor → "Get Info" → "Kind". Should be "Apple Silicon" or "Universal". Re-download if unsure.

Black 3D viewport

macOS uses Metal API instead of WebGPU directly. Macs from 2017+ fully support Metal. Check macOS version (Apple menu → About This Mac) — minimum macOS 12.

App won't start, no message

Open Terminal: open -W /Applications/Diaz\ Editor.app — shows error output. Send output to juan@diazatlas.com. Or check logs at ~/Library/Logs/diaz-editor/main.log.

Uninstall

Drag Diaz Editor.app from Applications to the Trash. License keys + projects remain in ~/Library/Application Support/diaz-editor (delete manually if desired).
