On macOS, install from the official tap:

Run this in PowerShell. The direct installer verifies the release and its checksum, installs to a user-local prefix by default, and prints the PATH command to use if needed.

Download the archive for your target and its adjacent .sha256 file from Colossus Releases. Copy both files to the target computer. Replace VERSION and TARGET below with the exact names you downloaded.

macOS:

shasum -a 256 -c colossus-VERSION-TARGET.tar.gz.sha256
tar -xzf colossus-VERSION-TARGET.tar.gz
./colossus-VERSION-TARGET/install.sh

Linux:

sha256sum --check colossus-VERSION-TARGET.tar.gz.sha256
tar -xzf colossus-VERSION-TARGET.tar.gz
./colossus-VERSION-TARGET/install.sh

Windows PowerShell:

$archive = "colossus-VERSION-TARGET.zip"
$expected = (Get-Content "$archive.sha256").Split()[0].ToLowerInvariant()
$actual = (Get-FileHash $archive -Algorithm SHA256).Hash.ToLowerInvariant()
if ($actual -ne $expected) { throw "Colossus checksum mismatch" }
Expand-Archive $archive
