For anyone who is still having trouble installing this, I just tried and quickly succeeded using the nix installer on Mac. Nix is an independent package manager for Linux and Mac that precisely specifies and isolates all dependencies from the system and other packages, so it often resolves broken dependency issues.

The commands I ran:

To install the nix package manager:

curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install (You may have to restart your terminal now if it can't find the nix command.)

To install threadscope:

nix profile install nixpkgs#haskellPackages.threadscope To run threadscope:

threadscope
