  1. Download the .dmg file from the releases page

Since AirShare is not signed with an Apple Developer certificate (costs $99/year), macOS will show a security warning.

This is normal! AirShare is completely safe - the code is open source and publicly auditable on GitHub.

  3. Scroll down to find "AirShare was blocked from use"
  4. Click "Open Anyway"
  5. Confirm by clicking "Open"

Method 3: Terminal Command

Open Terminal and run:

xattr -cr /Applications/AirShare.app

Then open AirShare normally from Applications.

Windows Installation

Step 1: Download and Run Installer

  1. Download the .msi file from the releases page
  2. Double-click the .msi file to start installation

Step 2: Windows SmartScreen Warning

Since AirShare is not signed with an Extended Validation certificate (costs $300-500/year), Windows may show a SmartScreen warning.

This is normal! AirShare is completely safe. The app is open source and builds are cryptographically signed for updates.

When You See "Windows Protected Your PC"

  1. Click "More info" on the SmartScreen popup
  2. Click "Run anyway"
  3. The installer will proceed normally

Step 4: Grant Firewall Permission

This is required for AirShare to discover other devices and transfer files.

Optional: Add to Startup

Linux Installation

Linux users have two options: AppImage (works on all distros) or .deb package (Debian/Ubuntu).

AppImage works on any modern Linux distribution without installation.

Step 1: Make it Executable

chmod +x AirShare_*.AppImage

Step 2: Run It

./AirShare_*.AppImage

Step 3: Optional - Integrate with Desktop

Most desktop environments will offer to integrate the AppImage automatically. Or use AppImageLauncher for automatic integration.

You can also manually create a desktop entry:

# Move to a permanent location
mkdir -p ~/.local/bin
mv AirShare_*.AppImage ~/.local/bin/airshare

# Create desktop entry
cat > ~/.local/share/applications/airshare.desktop << 'EOF'
[Desktop Entry]
Name=AirShare
Exec=/home/YOUR_USERNAME/.local/bin/airshare
Icon=airshare
Type=Application
Categories=Network;FileTransfer;
Comment=Lightning-fast file sharing
EOF

Replace YOUR_USERNAME with your actual username.

Option 2: .deb Package (Debian/Ubuntu)

sudo dpkg -i AirShare_*.deb
sudo apt-get install -f  # Install dependencies if needed

Then launch from your application menu or run airshare in terminal.

Firewall Configuration

If you use a firewall, you need to allow AirShare:

UFW (Ubuntu/Debian)

sudo ufw allow from 192.168.0.0/16 to any port 59875:59925 proto udp
sudo ufw allow from 10.0.0.0/8 to any port 59875:59925 proto udp

Firewalld (Fedora/RHEL)

sudo firewall-cmd --permanent --add-service=mdns
sudo firewall-cmd --permanent --add-port=59875-59925/udp
sudo firewall-cmd --reload

mDNS/Avahi Requirement

AirShare uses mDNS for device discovery. Most distributions have this pre-installed, but if not:

# Debian/Ubuntu
sudo apt-get install avahi-daemon

# Fedora/RHEL
sudo dnf install avahi

# Arch Linux
sudo pacman -S avahi
sudo systemctl enable --now avahi-daemon

Troubleshooting

"Permission denied" when running AppImage

chmod +x AirShare_*.AppImage

AppImage won't run on older systems

Try extracting and running directly:

./AirShare_*.AppImage --appimage-extract
./squashfs-root/AppRun

AppArmor / SELinux Issues

AppArmor (Ubuntu):

sudo aa-complain /path/to/airshare

SELinux (Fedora/RHEL):

sudo semanage fcontext -a -t bin_t "/path/to/airshare.*"
sudo restorecon -v /path/to/airshare*
Installation complete! Jump to the Quick Start Guide to send your first file.

Verifying Your Installation

After installation, verify AirShare is working:

  1. Launch the app: You should see the AirShare window
  2. Check the tray icon: Look for the AirShare icon in your system tray
  3. Test discovery: If you have another device with AirShare, they should discover each other automatically
Tip: Install AirShare on at least two devices to test file transfers!

Updating AirShare

AirShare includes an automatic updater that checks for new versions on startup.

When an update is available:

  1. You'll see a notification
  2. Click to download and install
  3. AirShare will restart automatically
All updates are cryptographically signed for security.
