It’s a good idea to secure your Mac from prying eyes, and it doesn’t take a lot of work to set some basic security to Mac OS X. This will help protect a Mac and the important files you have on it, and I consider the following three tips to be 100% necessary for almost all Mac users, particularly if you’re either in a shared computing environment, an office, school, public place, and especially if you have a laptop.

Each of these three security tricks can be enabled via the System Preferences with the Account pane and the Security pane, respectively. What you’re going to be doing is requiring a password if the computer is woken from a ‘sleep’ state, including a screen saver, and also preventing the automatic login process, thus requiring a password to be entered if a Mac has been booted up or restarted. Finally, you’ll learn a simple keystroke to lockdown everything anytime you step away from the computer, thereby increasing the protection by restricting access.

Don’t worry if you’re not sure where to begin, we will walk you through the simple steps and you’ll have some added protection and security added to your Mac in just a few minutes.

If you’re wondering how to mount an ISO image in Mac OS X, it is very easy. For most ISO images you can mount them simply by double-clicking the ISO image file, and it will go through the auto-mounter app within Mac OS X putting it on your desktop.

If for whatever reason that doesn’t work there are other methods to mount ISO’s within Mac OS X, and we’ll cover ways to do this with the built-in Disk Utility and a more advanced option of using the command line.

Update – May 2011: We have written an up to date article on exactly how to change a short user name in Mac OS X. Please refer to that for further assistance, it will work on Snow Leopard and prior versions.

A while ago I made a typo when creating my short username in a fresh Mac OS X install, I figured it wasn’t a big deal and that I could change it easily in the User accounts system preference pane, but boy was I wrong. Unfortunately, changing your short username is not a matter of typing a new name in a field, but thankfully there are two fantastic write ups on three ways to change the short username in Mac OS X 10.5 Leopard.

The first tip, involving the creation of an alias by accessing an ‘Advanced Options’ area within the Accounts preference pane, is pretty nifty. You can access this area by doing the following:

Step 1): Unlock the Accounts preference pane by clicking on the lock icon
Step 2): Right click (or Control click) on the name of an account in the list and choose “Advanced Options” from the resulting menu.

So that’s where you create an alias and do some other fancy things, but this isn’t really a solution to the short username problem I had. So what else can we do? You can read the Macworld article or our own OSXDaily: Change a short user name in Mac OS X

A MAC address is a unique identifier assigned to your network card, and some networks implement MAC address filtering as a method of security.

For the purpose of this article, we are going to assume you want to spoof your Mac’s wireless MAC address, meaning your wi-fi card.

Without further ado, here’s a three step process on how you can spoof and change the MAC address in macOS and Mac OS X.

The Unofficial Apple Weblog has a decent post listing 10 useful Quick Look usage tips, some are built right in and won’t require modification, while others will require 3rd party plugins to use. Here’s the full list, minus the detail:

1. Identify files on remote machines.
2. Preview the contents of Zip files (plug-in required).
3. Preview the contents of a folder (plug-in required).

7. Enhance TextMate.
8. Preview fonts.
9. Quick Look and Cover Flow.
10. Send images to iPhoto.

The Mac OS X desktop is attractive, highly functional, and very customizable, but by default the maximum icon size is 128×128 as adjusted through the normal Mac icon size settings.

While 128 x 128 pixels is pretty large, if you have a huge monitor, or you’re visually impaired, you may want larger icons so that they’re easier to see. This is where the command line comes in, where you can use a defaults write command to force the Mac OS X desktop to display icons as large as 1024 x 1024 pixels!

To do this yourself, launch the Terminal and type the following commands:

The appearance of the new Dock changed in Mac OS X 10.5 Leopard which has caused somewhat of an uproar in the Mac community, some of whom even claim it looks like it belongs in Windows Vista. That change stuck around in later versions of OS X as well.

If you’re totally insulted by the new 3D dock, or if you just prefer the old Dock appearance, it’s very easy to change and you don’t need to be a super Mac genius to figure it out.

Simply launch your terminal and type the following commands:

Quick Look is a nice feature in Mac OS X for quickly previewing documents, images, and other file data before opening it into a designated application. I use Quick Look often for glancing at the content of various documents and it certainly beats launching an application when you just need to take a quick peak at something, whether it’s to confirm contents or verify you’re working with the proper file. If you’re an avid command line user though, you may be browsing through a directories contents and wondering just what is that JPG or DOC file.

Wonder no more, because you can easily use Quick Look from the command line of Mac OS to open Quick Look previews right from the Terminal application.

Many of us who converted from a Windows PC to a Mac may long for the amazing artistic capabilities allowed within Microsoft Paint.

Did you know you can navigate Mac OS with only the keyboard? If you’re an avid typer it can be annoying to have to interrupt your flow, lift your hand(s) from the keyboard, simply to use the mouse and navigate around Mac OS X.

Many of us intel Mac OS X users installed Boot Camp partitions so we could run Windows or Linux on the same machine as our Mac. Boot Camp is great, but it’s annoying when you have to reboot just to access the other operating system, which is why something like VMWare is so useful.

If you’ve been using Boot Camp for a while though, you probably don’t want to lose what you’ve been working on within that partition. That’s where this comes in, you can convert a boot camp partition (well, technically any Linux or Windows partition!) to a VMWare virtual machine, so that it can run inside the virtualization software.

Have you ever wished you could see the complete file system path in the titlebar of a Finder file system window? Well you can use a secret setting in Mac OS X to display the path in the titlebars of windows. The geekier Mac users amongst us and those familiar with the unix world should really appreciate this, but really it’s useful for anyone who just likes to know where they are currently located within the file system.

To change the Finder window titlebars to display the full directory path, you’ll need to use a defaults command string entered into the Terminal.
