Trust me: Don't blindly install everything that Apple provides via Software Update.
Specifically, you need to
read the instructions for all updates before you begin any update.
I've been reading lots of readers caught in gotchas caused by the
Power Mac G4 Mirrored Drive Doors Firmware Update, the Mac OS X
10.2.2. update, and other installations. For many of these users, the problem comes down to neglecting to think about what you're doing. Hell, even I've been guilty of doing this a few weeks ago when I updated my MDD Power Mac to 10.2.2,
knowing that it would hose my computer due to a bug with the HP printing software that causes its drivers to hog processing time until your Mac slows to a crawl or kernel panics.
And why did I do it? Because I wasn't thinking. I was caught in that Macintosh mode of thinking where we expect the moon and the stars from anything that Apple provides to us, especially if it's a freebie. It's a different psychology than what some PC users may understand, where caution is much stronger than in the Macintosh world. When most Mac users buy software, we rip the CD from the case, install the software, and damn any manuals or instructions that come with the program. In the earlier years of the Macintosh, this wasn't as much of a problem because of the simpler design. However, this ain't your dad's Mac. It's
your Mac, and it's running not only a different Mac OS, but likely has a dramatically different hardware design that requires a little more care.
Professionals and home users need to use some common sense steps for any software update or install:
1) READ the instructions about any software installation or update.
2) UNDERSTAND what the update or install is supposed to do. If you don't understand the purpose of a particular update, don't install it until you find someone that knows and can explain it to you.
3) WAIT several days after an update is introduced before you even THINK about installing an update. If there are real problems with the software itself, this problem will show itself from the many trouble reports you'l see on the Internet. In other words, let other more careless people "beta-test" the updates for you in advance.
Two good places to visit for trouble reports are
MacFixit or
Apple's Discussion Boards on their Support Page.
4) READ the instructions for the update again.
5) PRINT a copy of the instructions BEFORE you begin.
6) DETERMINE A PLAN to revert the change (if the update allows it)
7) DECIDE if the update is really worth installing.
Remember that users who have tweaked their Mac OS X installation dramatically (read: against Apple's recommended configuration) may experience a bad time. If you have hacked an old Mac (read: not an original G3 or G4) to run Mac OS X, you should already know that you're running the bleeding edge of compatibility.
It's a good thing that we have BSD underneath our Mac OS GUI. It leaves many more possibilities for repairs or changes, unlike in the old Mac OS 9 days where we'd have to wait for Apple to get with the problem and provide a fix. A good example: after the HP printer software problem appeared with the 10.2.2 update, several enterprising people developed
several workarounds and temporary fixes while Apple and HP slowly find an official solution.
Your mileage may vary with any update. Don't experience
"Go Fever" with your Macintosh, or things could blow up real good.
