System requirements¶

Platform	Minimum	Architectures	Distribution
iOS	iOS 16	arm64	App Store
iPadOS	iPadOS 16	arm64	App Store
macOS	macOS 13 Ventura	Apple Silicon + Intel	App Store
tvOS	tvOS 17	arm64	App Store
Android	Android 8.0 (API 26)	arm64-v8a, armeabi-v7a	Google Play + direct APK
Android TV	Android 8.0 (API 26)	arm64-v8a, armeabi-v7a	Google Play + direct APK
Windows	Windows 10 or 11 (64-bit)	x64	Signed installer (.exe)
Linux	glibc-based distros	x86_64, aarch64	.deb, .rpm

Windows installs a TUN driver and therefore requires administrator rights during installation.
Windows 7, 8 and 8.1 are not supported, nor is 32-bit Windows. The app is built on Electron 33, which runs only on Windows 10 and newer, 64-bit; on an older or 32-bit system the executable is not even recognised as a Windows application. From desktop build 202 the installer checks this first and stops with a clear message instead of installing a copy that cannot start.
Linux packages install a small root helper service, so connecting doesn't prompt for a password every time. Proxy-only mode needs no root at all.
Android requires the system VPN permission, granted once on first connect. Devices with aggressive battery management may need SMProxy excluded from optimisation for the tunnel to survive long background periods; the always-on option makes this more robust.

Code signing¶

Platform	Signature
Windows	Signed with an OV code-signing certificate issued to RB Media FZC LLC by Certum. The installer and every bundled executable are signed and timestamped, so Windows shows a named publisher instead of “Unknown publisher”, and SmartScreen/Defender warnings are correspondingly reduced.
macOS, iOS, tvOS	Signed and notarised by Apple; distributed through the App Store.
Android	Signed with the developer key; Play builds additionally re-signed by Google Play.
Linux	Packages are not signed; verify downloads against the checksums published with each release.
