Install LocalDrop.Dev on macOS
LocalDrop.Dev is signed by our Apple Developer Program certificate and notarised by Apple, so installing the DMG is two drag-and-drops. If you'd rather skip the manual step entirely, the Mac App Store version auto-updates and never asks anything.
1 Download and install
- Grab the DMG: LocalDrop.Dev-1.1.4-macOS.dmg (27 MB)
- Open the DMG, drag LocalDrop.Dev onto Applications
- Eject the DMG (right-click on desktop → Eject)
2 First launch
Double-click LocalDrop.Dev in Applications. The very first time you run it, macOS will show a one-line confirmation:
"LocalDrop.Dev" is an app downloaded from the Internet. Are you sure you want to open it?
That's the standard "downloaded from the internet" prompt macOS shows for every signed app from outside the App Store. Click Open — that's it. Future launches won't ask again.
No "Open Anyway" detour, no Privacy & Security panel — that's the experience for unsigned apps. LocalDrop.Dev is signed, so the friendly one-click prompt is all you'll see.
Want zero prompts?
Install LocalDrop.Dev from the Mac App Store — automatic updates, sandbox-protected, no first-launch confirmation. Same app, same features, plus universal-purchase if you also use the iOS version.
You can inspect every line of source code on GitLab either way.
Troubleshooting
- Make sure the app is dragged into
/Applications— running it directly from the mounted DMG can occasionally trip Gatekeeper. - On Apple Silicon Macs, install Rosetta 2 if prompted — System Settings does it automatically the first time.
- If you see a hard "developer cannot be verified" block (only happens on very old DMG builds): right-click the app in Finder → Open → Open on the confirm dialog. Then download the latest DMG above and you'll get the smooth flow next time.
