Know before you install
Mac and Linux currently connect to a Windows host. Sharing a Mac or Linux desktop is separate work. The previews use the same account, pairing and per-person permission model as Windows.

Extract the ZIP and move APE Viewer to Applications. macOS Keychain must be available for protected sign-in and pairing keys. This preview has an ad hoc integrity signature, not a Developer ID signature or notarization. If macOS or Keychain refuses it, keep the protection enabled and report the problem. Intel Macs are not included.
Extract the archive and read its README for your distribution's required packages, then run ./apeviewer from the extracted folder. Use a normal signed-in desktop with an unlocked Secret Service keyring such as GNOME Keyring. X11 clipboard is supported; Wayland clipboard is not yet available. The archive does not install a system service or configure your firewall.
