It is there, but seems to be essentially abandonware. The ‘mate’ command line tool to launch the app fails more than half the time on Apple Silicon, the plugins and bundles that exist are years out of date for Ruby and Rails, and I don’t expect it’ll ever get support for LSP. So, sure, TextMate still exists. It’s still my default scratchpad for modifying text, and I even use it for some light scripting from time to time, but I don’t actually use it to build and maintain complex software any longer.
