While I’m here on my 3rd Apple Store visit in as many days to try to recover from a disaster triggered by my attempt to upgrade my Mac to the Snow Leopard OS X, here are some tips that might save other Mac users similar pain and frustration.
1. Back up your entire machine onto TWO EXTERNAL DRIVES. It’s a good idea to run Time Machine backup as often as possible. But when you’re running the risk of having to hand over your mac AND your backup drive to a technician (which is always the case when attempting a significant operating system update), it’s a good idea to have a separate copy of your backup in your own possession.
2. Verify the condition of your hard drive. Apple is marketing Snow Leopard chiefly as a way to enhance performance. However, if your hard drive is developing problems (as mine apparently was), that will impair performance. Installing Snow Leopard won’t fix HD problems, and it may even cause your drive to fail during installation (as mine did)
So Verify your disk using your Mac’s Disk Utility before you upgrade. That can indicate HD problems. It’s not a perfect predictor of problems, but it’s at least some help. Had I thought to do this, I might not have lost 3 workdays and be freezing my ass off in an over-air conditioned Apple Store right now.
If your disk verification process indicates problems, and if you’re experiencing decreasing performance, it’s probably a safer bet to get your HD replaced and data restored correctly BEFORE attempting to upgrade your operating system. If you have to go to the Apple Store to do this, make sure they put in the work order that you do NOT want the OS upgraded yet.
3. Check your warranty coverage. I purchased Apple Care when I bought my mac a couple of years ago, and it’s still in effect. So Apple replaced my HD for free. I’m not sure whether the warranty covers drives that are having problems (rather than have already failed), but it’s worth asking about.
4. Line up a backup computer. If, like me, you work or life could get seriously screwed if you lose your computer for a few days or more, make sure you have handy access to a functional backup machine BEFORE doing a significant system update. Load it up with all the software & data you’ll need to do what you need to do, and test it.
Personally, I’m getting a Linux netbook ASAP.
5. Check your ProCare staus. ProCare is Apple’s preferred service program. It costs about $100/yr, and it’s worth it if you depend in your Mac. If you need a speedy repair, make sure you have current ProCare coverage. You van buy it on the spot at the Apple Store if you need it.
6. Don’t leave the Apple Store without your computer the way you need it. If your OS X update goes dreadfully wrong (as mine did), required them to wipe your drive, have the Apple Store staff restore your operating system and data from your Time Machine backup. Don’t do all of that yourself.
My experience shows that this installation/restore process is trickier than Apple claims. It’s surprisingly easy for the Time Machine restoration to not work right with a freshly installed OS. Make them do everything you need do your machine is up and running. Bring this blog post with you if they balk, and stick to your guns.
This means bringing your external HD with your current Time Machine backup to the Apple Store with you, of course. And before you leave, sync your iPhone and make sure it works. My iPhone sync is not yet working, so I’m staying put in this store for now.
7. Check the “Lemon Law” in your state. The details if this federal consumer protection law are defined by each state. In many states, including CA, lemon laws cover not just vehicles but also consumer products. This may give you recourse if you get screwed by Apple on mac-related issues, like a disastrous OS update you paid for.
Also have the phone number of the local Better Business Bureau handy, and be willing to file a complaint if necessary.
8. Don’t attempt a major system update a couple of weeks after having knee surgery. I’m just saying, it makes everything that much more difficult, aggravating, and risky.
