This is a list of eleven startup key commands that every Intel Mac owner should make note of. From reseting your NVRAM, starting up in safe mode, booting your Mac from a CD or DVD, switching bootable volumes and drives on system start, to forcing media to eject from a superdrive, this list has you covered.

While some of these commands are the same as what worked for PPC Macs, others are slightly different or completely new, and so even longtime Apple users should find something helpful. Great for troubleshooting, system administration, and just furthering your general knowledge about Mac’s.

According to this Security update, eight dangerous security flaws have been discovered and squashed inside Apple’s QuickTime product.

Some of these holes in QuickTime can give a hacker full control of your computer.

According to Apple, the problems lie in the way QuickTime handles MOV, MIDI, 3GP, PICT and QTIF files.

Security is the number one topic these days when it comes to operating systems and its refreshing to see Apple “on top” of these potentially disastrous bugs.

Be sure to run the Software Update utility on your Mac and get the latest!

Copy and Paste are absolute necessities for virtually all computer users, and if you find yourself working in the command line frequently, you’ll want to know how to manipulate the clipboard of Mac OS X directly from the terminal prompt. That’s what the Mac commands pbcopy and pbpaste are for, and as you may have guessed the two commmands do exactly what they sound like, pbcopy is to copy, and pbpaste is to paste through the command line. They’re actually quite powerful and you’ll be sure to find them useful the next time you’re hanging out with your bash, tcsh, zsh, or whatever is your preferred shell prompt.

We will cover a quick explanation on how to use pbcopy and pbpaste to manipulate clipboard data, with some examples indicating how to redirect the output of terminal commands as input into the clipboard, and of course, how to expel the contents of the clipboard into the command line with pbpaste.

Computing is all too often a serious thing, so it’s good to laugh every now and then about the subject. I stumbled upon a humorous read today regarding the troubles that new Mac users often run into. Personally I’ve been using Mac’s since the 80’s but I know there are many that are new to Apple hardware out there so these may ring true to yourself or someone you know. You’ll be sure to find some things in this list entertaining, like #14. Thinking it’ll be easy to get a stuck CD out and #16. Where’s “the internet”?

A report on the Apple rumor site AppleInsider suggests that the release of Mac OS X 10.5 Leopard is further off than expected. For several months now, rumor sites have been speculating that Apple might be releasing 10.5 as early as late March, but the report from AppleInsider indicates there are too many bugs and quirks for Leopard to be released within the month. The latest build, 9a377, has some minor feature improvements, but also major problems such as crashes when QuickTime is played in Safari, and when the PowerBook G4 is woken up from sleep. Be sure to read the AppleInsider report for more information:

AppleInsider: Latest Leopard build from Apple suggests much work ahead

Here is a great feature that is widely unknown and certainly underused in Mac OS X, the ability to print nearly anything into a PDF document. Well, it’s not so much printing into a document as it is saving one, but you get the idea. I can think of a million uses for this, from ensuring cross platform viewing equality, to saving online tutorials and how-to’s for later reading. If you’ve never done this before, it’s extremely easy to do, and here’s how:

An incredibly useful feature that is built right into Mac OS X is the ability to create an archive instantly of anything, be it a single document, a folder, or multiple files. Creating archives is great for may reasons, they save space, and it’s a polite and easier way to send a group of files to someone else. Every once in a while we all get emails with a group of files attached that when we save the attachments, suddenly our desktop is littered with a mess of JPG’s, Word documents, and whatever else the sender attached. Spare someone else this annoyance by creating an archive first. Here’s how to complete the process and build a zip archive from any selected documents, files, or folders available in the Mac file system.

MediaFork is a lot like HandBrake, which is fitting because it is based on it. It allows you to easily rip any DVD or DVD source folder to various movie files that can be played on your Mac, PC, and iPod. MediaFork was created because HandBrake development has stagnated, so it’s really taking off where Handbrake left off. Ripping a full DVD can take upwards of several hours, depending on the speed of your Mac’s processor, but after it’s done you can transfer it to whichever media player you deem fit. It is worth noting that MediaFork is issued under the GPL, meaning free!

There are few frills other than what you absolutely must need to write, so don’t expect Microsoft Word.

The WriteRoom workspace is attractively presented in a simple retro green on black terminal-like appearance, although you can change the color scheme to whatever you want. Check out the screenshot below.

Mac OS X is wonderfully stable as an operating system, and although most software is written well, not all code is created equal. Crashing is just a fact of computing life and it frustrates us all, so it’s helpful to be able to pinpoint the cause of the problem. While the causes of some crashes are obvious, others are not, and this is when reading the Mac OS X crash logs can be so useful.

Bash is the default shell in Mac OS X and has been since 10.3, it’s generally considered to be the de facto shell standard in the unix world. That said, there are some people who prefer to use the tcsh shell, or perhaps you just want to break away from the norm. Changing the default shell is pretty easy, but you will likely run into problems when running bash shell scripts. If you want to experiment with tcsh and use it as your default shell, here’s how to do it from the GUI in three easy steps:

The folks at the Beatnik Pad have released new builds of Firefox 2.0.0.2. The Firefox update includes many security fixes some of which were deemed “critical”. For those of you are unfamiliar with Beatnik Pad’s Firefox’s builds, they are optimized at compile time for the G4, G5 and the x86 Mac OS X architectures. Beatnik Pad also offers a version of Firefox with Mac OS X style widgets, and one with the standard Firefox widgets. The site is also a good resource for a couple of plugins that can make Firefox behave more like Safari. My personal favorite is “Fission” which takes the “page load” status bar and places it in the address bar in a similar fashion to what you’d find in Safari. Read on for a screenshot!

Whether you’re a unix novice or veteran to the terminal, if you’re using the command line you’ll often find yourself looking up exactly how to use a specific command for either its understanding the commands full functionality or just to discover the proper syntax. Many of us will just google a command if we can’t seem to get things to work properly, but before you go that route you can also try the available resources that are built right in to the Terminal.

There’s no shame in needing assistance or needing to reference a manual page, so here are five ways to get some help right in the command line of OS X. Because most of these tricks are native to the command line and not OS X specific, they will work on a Mac and many other unix variations too, like Linux.
