A few useful answers
Before you get started.
Which computers are supported?
ShareJack is available for Apple Silicon Macs running macOS 12 or later, and Intel or AMD x64 Windows PCs. Install it on both computers before pairing.
Do my computers need to be on the same network?
You can share over the same local network or over the internet. For a first connection across different networks, create an internet invitation on one computer and accept it on the other. Internet sharing must be enabled on both devices.
Are my files stored in the cloud?
No. Files are transferred between your computers and are not stored on a server. Internet transfers use an encrypted direct connection when possible; a relay can forward encrypted traffic when a direct connection is unavailable.
Do both computers need to be online?
Yes. Both computers need to be running ShareJack and connected during a transfer. Pending sends are kept on the sending computer; ShareJack does not provide cloud storage or offline delivery.
Can I send a whole folder?
Yes. Drop a folder into the app or use the folder picker. Files and their subfolder paths are preserved. Empty folders, symbolic links and macOS-specific extended attributes are not transferred.
Can I remove a paired device?
Yes. Open Settings, find the allowed device and choose Forget to revoke its permission. A new pairing is needed before that device can connect again.
Keep your files moving.
Keep your flow.
