SeatbeltSeatbelt is a blazing-fast file transfer utility built from the ground up for macOS, with secure transfers using hash-verification, start/stop with resume (even between app launches), advanced sequencing of transfers, and extensive logging and scripting support.
After a year of development, I’m looking for beta testers who can take it for a spin, report bugs, suggest features, and ideally throw me a curveball I didn’t see coming. Everyone who participates will receive a discount code when Seatbelt launches later in 2026.
Beta Test Window
September 10 – October 15, 2026
During this period, I’m inviting users to try the app and help:
• Find and report bugs
• Suggest improvements
• Test security and transfer integrity
Requirements
• macOS 26 or newer
• Experience with media, file handling, or Mac workflows is a plus
