So You Want to be a Mac Tech

When I was about thirteen, my older brother, Craig, was really into cars and fixing them. I'd follow him around and watch him work on his Camaro in the garage. Like a doting little brother, I wanted to be like him and was awestruck at how much he knew about cars and engines. I can remember asking him how he knew so much about them and how I could learn what he knew. Craig handed me a huge stack of car magazines and told me to start reading. I was fla ergasted. Where do I start reading? Which do I read first? Is Car%26am Driver more important than SuperChevy? I can remember fli ing through a few of his magazines and quickly being overwhelmed at the amount of information I'd have to know to be like Craig. I soon went back to my Garbage Pail Kids cards and DOS manuals. I gave up on being a car mechanic but learned an important le on...the best way to start learning something is to just start learning it. It doe 't matter where you start as long as you start somewhere and keep at it long enough until the knowledge begi to gel in your mind.

Being a good Mac tech starts with knowing the Macintosh and its operating system--namely, Mac OS X. Good car mechanics are often filled with arcane knowledge about the vehicles they work on. They tend to know which parts break down first and can diagnose a problem from an exte ive knowledgebase of vehicles and engines and parts. I've discovered that good Mac techs are the same way--they tend to know pretty well the i ides of many different Macintosh models and the peculiarities of each. They know, for i tance, that the Rev. A iMac G5 often suffers from logic board failures and "exploding capacitors". They can often diagnose a problem--or if one is ha ening--just by using the computer in question.

The Fundamentals
You have to know Mac OS X, and I don't mean "know how to use Mac OS X." My Mom can use Mac OS X. A good Mac tech needs to understand the fundamental structure of the operating system and how the components relate to each other. For i tance, know what Frameworks are and how they differ from Exte io . You should understand the various levels of the operating system, like why there are three "Library" folders or four/five "Fonts" folders. If you're not sure about what's lurking underneath the glo y GUI that A le gives us, then start investigating. You don't nece arily have to change anything, but it doe 't hurt to look. Start reading some of the excellent tutorials on the Web like those over at kernelthread.com or ArsTechnica You don't nece arily have to understand everything right away. Just immerse yourself in the technology and eventually it'll start making se e.

Up-to-Date Knowledge
I don't care if you know how to use Conflict Catcher. Really, I don't. What's that, you say? You know that Suitcase 8 conflicts with the ATM control panel? Good for you. I'm sure that knowledge will we useful here in mid-2006 just like that certificate you got in operating a telegraph machine. I was that guy 10 years ago and I made a good living doing it, but that was the state of tech ten years ago. You don't want to be that guy today. The one exception to this that I'll grant is that there are still a few stu orn holdouts using Macs ru ing System 8 and Mac OS 9. If you're the unlucky soul that has to su ort these machines [waves at D.C.], then sure, keep that knowledge and use it. But you should probably be preparing yourself for the inevitable switch to Mac OS X (or to Windows, shudder).

Co ider Learning Scripting
Some Mac techs are lucky enough to have come from a Unix background and have mastered shell scripting. The best Mac techs I know are scripting wizards and can whip together a script to do almost anything. That is the true power of Mac OS X, you know. Its Unix underpi ings make it versatile, stable, and secure. Buy a good begi ing book on shell or Perl scripting and start experimenting. I am certainly not a scripting whizkid, but I've gotten to the point where knowing some scripting is helping to reduce my workload, which is the ultimate goal anyway, right? What's that? You like performing the same identical configuration task on each of 400 Macs?

Use the Resources and Stay Current
The Mac community, and by exte ion, the Mac technical community, are lively collectio of interesting, fascinating, and helpful people. Learn about we ites like AFP548.com and MacEnterprise.org. Lurk on some of the better Mac technical mailing lists, even if their subject matter is over your head. I su cribe to half-a-dozen Mac tech mailing lists (such as Mac-Mgrs, MacEnterprise, Mac OS X Server, and Tidbits) and the collected knowledge in their archives is incredible. If you su cribe to a list, just lurk for awhile and follow the list rules. I've found a Gmail account and its handling of email conversatio an astonishingly good fit as a mailing list receptacle. Whenever I encounter a new problem, I immediately turn to the mailing list archives (most are online and searchable) to see if anyone else has encountered the problem and whether there's a known solution or workaround. Another sometimes-overlooked but amazing resource are A le's own discu ion forums. The signal-to-noise ratio is quite high, but there are a lot of really smart people a wering questio , many of them A le employees.

Documentation
Practice keeping documentation of the problems you've solved, or at least bookmarks to sites where you found a solution. I've lost count of the number of times I've solved a problem, didn't document it, and then had to re-solve the problem 2 months later. Documenting your troubleshooting ste and proce will also improve your articulation, writing, and communication skills. You don't have to make your documentation public, but many people do. You might even contribute to the mailing lists or we ites that I've been talking about in this post, or even to that scra y little TUAW blog.

Co ider Certification
A le's profe ional certification program has come a long way in the last few years. They now offer several levels of technical certification and a wide range of cla es to better your knowledge of Mac OS X and its related technologies. If your goal is to be an attractive candidate for a Mac technical position, having an ACTC or ACSA certification is certainly going to carry more weight than having only Microsoft certs or no certs at all. For awhile, i was teaching some of A le's courses and know that the team of people they have working on the manuals and course design is very knowledgeable and competent.

Following some of all of this advice will likely get you started on your way to becoming a good Mac tech. There's a lot more that I could put in this post, and I'm sure that some of our readers will have things to add as well in the comments.

Oh yeah, remember my brother Craig who taught himself to be a car mechanic? Last Christmas he bought a computer. He was pretty new to computers so he asked me for help teaching him how to set it up and use it. I tried to explain to him what this whole Internet thing was about and what I do for a living. He looked at me and shook his head, "How on Earth do you know all this!? Jeez!" I smiled and handed him a stack of computer magazines and said, "Start reading."
