Setup Mac OS X

Edit: I've done the same process every couple years since 2013 (Mountain Lion, Mavericks and High Sierra).

I just replaced the hard drive of my mbp and decided to do a clean install of Mountain Lion (10.8.5) since I was still using Snow Leopard (10.6.8).

I kinda regret for not using Boxen to automate the process, but TBH I have this laptop for almost 3yrs and this is the first

Keeping the system updated is vital before starting anything on your system. This will prevent people to use known vulnerabilities to enter in your system.

sudo apt-get update

Encrypt text or files with OpenSSL

This has been very useful for Jamf policy / script parameters that contain passwords. It's not perfect because the passphrase and salt must be transferred as well, but at least it's not in cleartext...

Salt and passphrase

You can use OpenSSL to generate psuedo-random text which is more than enough for this tbh considering all the other problems this solution has. I believe the salt cant be more than 8 characters long cuz it's a hexidecimal value. Or it could be that both the salt and the passphrase need to be a valid hex string which means they could be longer just have to be a specific length. (Idk I could be entirely wrong on this).

Just do 8 and 12, I know that works.

	Mac Network Commands Cheat Sheet

	After writing up the presentation for MacSysAdmin in Sweden, I decided to go ahead and throw these into a quick cheat sheet for anyone who’d like to have them all in one place. Good luck out there, and stay salty.

	Get an ip address for en0:

	ipconfig getifaddr en0

	Same thing, but setting and echoing a variable:

	#!/usr/bin/python

	Run as root to update all users or as normal user to update just that user.
