I really got into Linux by setting up servers on CentOS back in 2007. Linux, the resources and the community are great and the fact that those servers still run fine today is a testimony to that.

If you have some time and you would just like to read some good basics start with http://www.linuxfromscratch.org/lfs/view/stable/prologue/for... and go as far as you can.

If you would like to get down and set up a server grab a Debian install kit.

The other option would be to get a RaspberryPI and start with that. Tons of resources and much closer to the hardware as a server install. Good if you re into electronics too.

I am a Mac user myself and you will find that the BSD underneath is mostly what Linux works like. They do say that MacOS is the best BSD available :-) So learning Linux will definitely help you to get much more from your Mac as well.

Have fun!
