Today I was tinkering with Cocoa, and drew a simple rectangle then added a small arrow head to it.

Today, I am releasing my first “useful” Cocoa application. Its called “LockIt”

It locks your mac screen whenever you need to step away from it for whatever reason. I designed it so that my brother doesn’t tinker with my Mac when I’m in the middle of writing code but need to have a drink or go to the loo.

I know you can get KeyChainAccess to do similar thing, but I wanted something different. Also in the works is support for adding keyboard shortcuts.

It is just a simple application that hasn’t got any bells and whistles. So any ideas or suggestions are welcome.
