Lime is available as a native Mac application for faster performance and better integration with your desktop workflow. Download and install it once, then access Lime directly from your Mac without opening a web browser.
Lime is also available as a Windows app.
Download the Mac App
- Go to the Lime downloads page
- Select the correct version of the app - click the Apple icon () in the top-left corner of your Mac screen and select “About This Mac”. If it says “Chip” (e.g. Apple M1, M2, M3), it is Apple Silicon. If it says “Processor” (e.g. Intel Core), it is an Intel-based Mac
- Open the downloaded file
- Drag Lime to your Applications folder (and your Dock)
- Launch Lime from Applications
Keychain Access Permission (First Launch)
When you first open Lime on Mac, you’ll see a keychain access permission prompt. This is expected and necessary for Lime to work properly.
Why this happens:
Lime needs to securely store your login session and authentication tokens on your Mac. macOS Keychain is Apple’s secure storage system for passwords, tokens, and encrypted data. Lime requests access to Keychain to protect your login information - the same way apps like Slack, VS Code, and other professional software do.
This prompt appears even though Lime is properly signed and verified by Apple. It’s standard behavior for applications that store secure session data.
What to do:
Click “Always Allow” when you see the keychain access prompt.
Choosing “Always Allow” means:
- Lime can securely store your encrypted login session
- You won’t be prompted again every time you open the app
- Your Lime account stays logged in between sessions
- Your data remains secure in macOS Keychain (Apple’s encrypted storage system)
If you click “Deny,” Lime won’t be able to store your session securely, which means you’ll need to log in every time you open the app and may experience authentication issues.
Troubleshooting
“App can’t be opened because it’s from an unidentified developer”
This shouldn’t happen with properly signed Lime app, but if it does:
- Right-click (or Control-click) the Lime app in Applications
- Select “Open” from the menu
- Click “Open” in the dialog that appears
- Lime will open and remember this permission going forward
Keychain prompt appears repeatedly:
If you clicked “Deny” initially, you may see the prompt again. Click “Always Allow” to resolve this permanently.
App won’t launch:
Ensure you’re running a compatible macOS version. Check for app updates if you installed an older version.
