I came across a pretty useful page today about securing your Mac, and while none of the tips are rocket science or particularly advanced, I still found it to be useful enough to want to share with everyone. The first two tips are definitely what I consider to be 100% necessary if you’re either in a shared computing environment, or if you have a laptop, and I have repeated them here. Both of these can be done via the System Preferences with the Account pane and the Security pane, respectively.

Secure your Sleeping Mac by requiring password upon wake from sleep or screensaver

1) Go to Apple Menu > System Preferences > Security
2) Click on General section
3) Enable password prompt to wake computer from sleep or screen saver, which is done by clicking the first checkbox

Securing User Accounts - Disable Automatic Login

1) Go to Apple Menu > System Preferences > Accounts
2) Click on the Lock to make changes
3) Choose Login Options
4) Disable automatic login, so strangers will require password to access into your Mac

Like I said, I consider those two tips to be 100% necessary, but there’s 8 other great tips that you might find useful so check those out here: 10 most essential things for securing your Mac
