Install

GitLane isn’t notarized by Apple yet, so Gatekeeper blocks the app after download — usually with “GitLane is damaged and can’t be opened” on Apple Silicon, or “unidentified developer” on Intel. macOS flags every non-notarized download this way.

Copy the app to Applications, then clear the quarantine flag once:

xattr -dr com.apple.quarantine /Applications/GitLane.app

Then launch normally. On some systems, right-click → Open, or System Settings → Privacy & Security → Open Anyway after the first blocked launch, works instead.

Updates delivered by the in-app updater don’t need this again.

Defender SmartScreen blocks a fresh download with “Windows protected your PC” and an unknown-publisher notice, with no obvious way to continue. Click More info, then Run anyway.

The installer installs for the current user, so no admin rights are needed. In-app updates don’t retrigger SmartScreen.

Prefer the .deb (Debian, Ubuntu, Mint) or .rpm (Fedora, openSUSE) package. Either gives you a normal install: app-menu entry, icon, and clean uninstall through your package manager.

sudo apt install ./GitLane-<version>-linux-deb.deb      # Debian / Ubuntu / Mint
sudo dnf install ./GitLane-<version>-linux-rpm.rpm      # Fedora / RHEL
sudo zypper install ./GitLane-<version>-linux-rpm.rpm   # openSUSE

The .AppImage is the portable fallback for every other distribution. Browsers never preserve the executable bit, so set it once:

chmod +x GitLane-<version>-linux-appimage.AppImage
./GitLane-<version>-linux-appimage.AppImage

A bare AppImage doesn’t integrate with the desktop — no app-menu entry or icon. Gear Lever or AppImageLauncher can add that.
