Desktop / PWA install or update failures
Last updated May 14, 2026 · 3 min read
Install- or update-level problems — find your scenario below.
Electron desktop (🚧 in development)
The following covers common desktop-app issues.
macOS: "Cannot verify developer"
The first time you open Slima.app, macOS Gatekeeper may block it:
Cannot verify developer
Fix: System Settings → Privacy & Security → "Open Anyway".
Windows: SmartScreen warning
"Windows protected your PC" appears:
Fix: click "More info" → "Run anyway".
Auto-update failed
- Confirm your network connection is working
- Once Desktop ships, you can re-download the latest from slima.ai and install over the top (currently 🚧 in development)
- Installing over the top won't touch your local data and settings
See: Desktop auto-update
Linux AppImage won't run
Most common cause: missing execute permission.
chmod +x slima.AppImage
./slima.AppImage
PWA
Can't add to home screen / dock
| Browser | How |
|---|---|
| Safari (macOS) | File → Add to Dock |
| Safari (iOS) | Bottom share icon → Add to Home Screen |
| Chrome / Edge | "Install" icon on the right of the address bar |
| Firefox (desktop) | Desktop Firefox doesn't support PWA install |
PWA update stuck
Clearing the cache usually fixes it:
- Hard refresh:
⌘⇧R/Ctrl Shift R - Or clear slima.ai's cached "site data" via your browser's own site settings, then re-enter
- iOS (Safari): remove Slima from the Home Screen, then "Add to Home Screen" again
None of the above worked
