Fix: “You can’t use this version of the application with this version of macOS” on ChatGPT Atlas
Many Mac users rushed to install ChatGPT Atlas expecting it to work like Chrome, Safari, or Arc. But on some machines, the excitement ends with a frustrating popup:
“You can’t use this version of the application with this version of macOS.”
I saw this error on two Macs: one on macOS Ventura and one on Monterey. Both installed successfully, but macOS refused to launch the app.
Originally, many people thought this was a bug or Gatekeeper problem. But after digging into the official documentation, the cause is clear: ChatGPT Atlas has strict hardware and OS requirements.

Why This Error Happens
1. Your Mac Uses an Intel Processor
According to OpenAI, ChatGPT Atlas only supports Apple Silicon (M1, M2, M3) machines. If your Mac says Intel, Atlas will not run — even if macOS is up to date.
2. Your macOS Version Is Too Old
Atlas requires macOS Monterey 14.2 or newer. If you're running an earlier version, macOS will block the app with this exact error message.
3. You Installed an Older or Beta Build
If you tried an early build or a re-uploaded installer, macOS may reject the newer version until old files are removed.
4. Downloaded from Outside the Official Source
Atlas should only be installed from OpenAI: https://openai.com/atlas

How to Fix It (Safe Methods)
1. Check if Your Mac Is Supported
- Click the Apple logo
- Select About This Mac
- If it says Apple M1 / M2 / M3 → ✅ Supported
- If it says Intel → ❌ Atlas will not run
2. Update macOS
Go to Settings → General → Software Update
Make sure you're on macOS 14.2 Monterey or newer. After updating, Atlas should open normally on supported devices.
3. Remove Old Atlas Files (If You Tested a Beta)
Delete these folders if they exist:
/Applications/ChatGPT Atlas.app
~/Library/Application Support/Atlas
~/Library/Preferences/com.openai.atlas.plist
Then reinstall from the official site. ChatGPT Atlas Download for macOS: Complete Guide and Installation Steps
4. Check macOS Security Settings
If macOS blocked the app because it came from an unidentified developer, go to:
- System Settings → Privacy & Security
- Scroll down and look for "ChatGPT Atlas was blocked"
- Click Open Anyway
Note: If you see “not supported,” this is not a permission issue — it’s compatibility.
