My Mac has been freezing lately so I spent some time trying to figure out why. There is a system process called LaunchServiceDaemon or /usr/libexec/lsd. It was using 100% CPU. Using information from this thread: What is the “lsd” process… and this one: /usr/libexec/lsd using 100% of CPU I found that lsd was trying to create a signature for apps in my Elixir projects. (I think because the names end in .app.) So lsd was trying to create signing signatures for hackney.app and mint.app. Once I deleted the _bulid directory from my elixir projects my Mac stopped freezing and CPU usage went to zero. You can check your own Mac like:

ps aux | grep lsd

look for the line with runAsRoot in it and find it’s PID then run:

sudo lsof -p PID

And look for a line includes an .app file in one of your projects like:

lsd     386 root    3r   REG   1,13     2686            77125471 /Users/someone/work/a_project/_build/prod/lib/tesla/ebin/tesla.app

So my question is how do I keep lsd from trying to create a signature for my elixir generated app files?
