I certainly hope it is easier to uninstall on OSX than Windows.
On linux, even if you have removed the uninstall script, you can still use your package manager by searching for installed Intel tools (although the Intel docs don't mention it). Surely OSX must have such a feature.
Tim, I agree. I'd written a KB article some months ago which should still apply and needs to be updated, at: https://software.intel.com/en-us/articles/uninstalling-intel-software-development-products-linux
