Whether you’re a systems administrator or a web developer, or anything in between, chances are you’ll have to flush your DNS cache every once in a while to get things straightened out server-side, or even just for testing certain configurations.

Flushing your DNS cache in Mac OS X is actually really easy, but there are actually several different commands to use, and you will find the commands are unique to different versions of Mac OS X. We’ve got you covered regardless of what version of Mac OS X you’re running, from MacOS Sierra 10.12, 10.11, 10.13, OS X 10.10, OS X 10.9, all the way back to 10.4. So find your version of OS X, open your Terminal, and follow the appropriate directions below to get started.

A MAC address is a unique identifier assigned to your network card, and some networks implement MAC address filtering as a method of security. Spoofing a MAC address can be desired for multiple reasons, and it is very easy to spoof your MAC address in macOS Monterey 12, macOS Big Sur 11, macOS Catalina, macOS Mojave 10.14, macOS High Sierra, Sierra 10.12, El Capitan, Yosemite 10.10, Mac OS X 10.4, 10.5, 10.6, 10.7, OS X 10.8, and OS X 10.9. 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.

A little known hidden trick allows for a nice cursor hover effect to follow your mouse as it goes over an application, folder, or item within an opened Dock stack of Mac OS X.

This makes navigating within Dock folder items a whole lot easier on the Mac and only takes a moment to turn on. To enable the secret option yourself with a defaults command, so here’s how to activate it.

Quick Look is likely the only feature in Leopard 10.5 that I actually notice and something I would certainly miss if I went back to 10.4, it’s just too useful. 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).
4. Examine snippets of code with syntax highlighting intact.
6. Prep your iWork documents for use with Quick Look.
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.

Here’s a really cool Firefox tip that was just passed along to me that allows you to instantly search on page text.

Here’s how this works: You can instantly search for any text on a web page by hitting the forward slash and typing that word.

So for example, you want to find “Firefox” on this page, you would type /firefox – that’s it!

Many of us who converted from a Windows PC to a Mac may long for the amazing artistic capabilities allowed within Microsoft Paint. Ok so maybe that’s a bit dramatic, and we all know that Microsoft Paint is pretty crappy in a weirdly lovable way, but that’s also why it was fun. So, if you came to the Mac you may miss mspaint, right?

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. Instead of dealing with that frustration, try using exclusively the keyboard in Mac OS, which can be used to access a lot of common things you would otherwise do with the mouse. No list is perfect, but here are fifteen useful keyboard commands and tips that I use on a regular basis that let you navigate through Mac OS X using only the keyboard.

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.

The appearance of Mac OS X has slowly been drifting away from the old aqua style to a more modern and refined look that closely resembles iTunes. The change in this direction was really made obvious within Leopard with the introduction of the coverflow style finder and the removal of the brushed metal windows. For some reason, Apple ignored the scrollbars though, and we still have Aqua-styled candy looking scrollbars when everything else resembles iTunes. So you had to figure it was only a matter of time before a crafty Mac user would change that, and here we have it. Installation is very easy, but I would backup the .rsrc file before you replace it with this new version.

Update: The usage of third party tools for NTFS support is no longer necessary, as Mac OS X includes NTFS read & write support natively, here’s how to enable it. While newer versions of the Mac operating system support NTFS without any third party add-ons, older versions of OS X may still find value in MacFUSE. Keep in mind that if you’re in OS X 10.7, 10.8, 10.9 or newer – this is not necessary, and thus this article is really only relevant for much older versions of Mac OS X before 10.5.

I recently came across a great utility called MacFUSE which allows Mac OS X users to read and write to NTFS partitions, amongst other things. This is extremely useful if you have an external storage device you use on both a Mac and PC, and you want to avoid the limitations of FAT32.

Getting MacFUSE to work in OS X 10.4, 10.5, and 10.6 is not the easiest process in the world, and it takes some knowledge and patience to get functioning properly. Thankfully, LifeHack.org has a pretty decent walkthrough on setting up MacFUSE, so check that out if you’d like some guidance.

• Get MacFUSE from the dev source
• Read the Lifehack guide on getting it to work

Again, this is for older versions of OS X like 10.4 Tiger, 10.5 Leopard, and 10.6 Snow Leopard. remember that new versions of OS X do not need to use MacFUSE to read and write to NTFS! You can follow this simple guide to enable NTFS in OS X Mavericks, Lion, Mountain Lion, and newer.

People seem to either love or hate the dock in Mac OS X Leopard. Maybe it’s the appearance, the reflection, or something else.

If you’re not a fan of the default ‘swoosh’ reflective Dock, there are many options available, and a site has popped up catering to nothing but Leopard Docks.

Yes indeed, customized Mac OS X 10.5 Leopard docks, so you can change the appearance to suit your preferences a bit.

Aptly named LeopardDocks.com is dedicated to nothing but customizing your Leopard dock, with everything from shiny wood surfaces to grass.

Check out LeopardDocks.com for more

You’ll need to make a few modifications to install the custom Docks, but it shouldn’t be a huge hurdle to anyone who has an urge to tinker with their Mac system.

If you’re a Mac user and you installed the Adobe CS suite for graphic work or web development, you probably aren’t too interested in Adobe SoundBooth, which is fine because you don’t have to install it. Well, I didn’t install Adobe SoundBooth and I discovered that Adobe still decided to install 5GB of SoundBooth bloated files into my home directories Library folder. I have no idea what the purpose of this stuff is, but if you don’t use SoundBooth (I don’t even know what SoundBooth is) you don’t need it, and 5GB is a lot of disk space for something I don’t use. So here’s how to get rid of it:

Free up 5GB of disk space by deleting Adobe CS bloat

Step 1) Navigate to /home/Library/Application Support/Adobe/SoundBooth/

Step 2) Delete anything inside the SoundBooth folder (only do this if you don’t use or need SoundBooth, obviously)

Step 3) Enjoy 5GB of extra disk space!

Earlier today Microsoft released the second beta of their Remote Desktop Connection application. This new version introduces an updated user interface (not sure if its worse or better), Universal binary support, Vista support, dynamic window resizing and quite a bit more. It is good to see Microsoft update this utility as it is a crucial part of my workflow. The previous version of the Remote Desktop Connection was a PowerPC only application that was quickly becoming dated. I was able to verify that this new version works flawlessly in OS X Leopard. Read on for a complete list of new features and a screenshot.
