CCIso for macOS is available as a free download.

CCIso isolates Claude’s programs so their traffic leaves only through the one channel you choose; if the channel goes down, Claude is blocked instead of connecting directly. The current focus is outbound controls and specific credentials; full local file-access isolation is not complete.

If a download does not work inside WeChat, use “···” in the top-right corner and choose “Open in Browser”.

How to verify a file

Every release includes SHA256SUMS with the checksum for each file. Use the commands below to calculate the SHA256 of your download, replacing the filename with the file you actually downloaded (the Windows and Linux commands apply once those versions are released). Checksum file: https://chan007.cc/download/SHA256SUMS

macOS (Terminal)

shasum -a 256 ~/Downloads/CCIso-0.1.7.pkg

Windows (PowerShell)

Get-FileHash .\CCIso-<version>-setup.exe -Algorithm SHA256

Linux (Terminal)

sha256sum cordon_<version>_amd64.deb

Compare the calculated SHA256 with the value published for that version. If they differ, do not run the file; confirm its source and integrity first.

How to check signatures

macOS: the installer is signed with Developer ID and notarized by Apple. In Terminal, from your download folder, check the installer; the result should include source=Notarized Developer ID:

spctl -a -vv -t install CCIso-0.1.7.pkg

After installation, you can also check the installed app:

spctl -a -vv /Applications/CCIso.app

Windows: the signer will be published with the Windows release. Then check Properties → Digital Signatures on the installer, or use PowerShell; Status should be Valid:

Get-AuthenticodeSignature .\CCIso-<version>-setup.exe

Linux: package verification instructions, signing public keys and fingerprints for any provided repository will be published with the Linux release.

Where download addresses are published

  • The primary address is the download button on this page. Installers are served from the independent download directory on chan007.cc, with SHA256SUMS in the same directory.
  • Any alternative download address will be listed for the relevant release.
  • Only run an installer downloaded from this page whose checksum and signature both check out. Do not run files from unknown sources.
