Let’s face it—Macs do have problems. Sure, they don’t crash as often or as horribly as PCs do but incidents of OS problems crop up here and there every now and then. Sometimes, in fact, the only way to get rid of the problem is to do a fresh reinstall of Mac OS X.
Although Time Machine can very well restore your system to a time before you muddled it up, reinstalling the OS can bring some good performance improvements. Going the clean install route entails you having to move all your data from your hard drive to an external drive and then copying it back once you’re done. Of course, you could do an Archive and Install which will leave your document files intact, but what about the application related data that an Archive and Install often messes up? Having gone through this similar situation, I have decided to create a checklist before reinstalling your OS—because you somehow always forget to do one important task which you cannot go back to later on.
1. Address Book and iCal. Just launch each app and back them up. Both apps have Export options right in the File menu. If you are a MobileMe subscriber, your calendars and contacts are synced to the cloud so there should be no worries about losing that data. However, I would still suggest you make backups as MobileMe might corrupt your data, at least in its current flaky state.
2. Your Pictures. Just copy over your iPhoto Library and whatever other pictures you have in your Pictures folder. The iPhoto Library will appear as one big file. You do not want to take the risk even with an Archive and Install. Remember, you can never get the cat to pose like that ever again.
3. iTunes Library. If you have painstakingly set ratings for songs and maintained playcounts, it will hurt to lose all that and have just plain music in your library. Copy over your entire iTunes folder over to an external drive. The iTunes music folder will be in your ~username/Music folder. Copy the full thing over (replacing the one that already exists). [Ed note: For a more detailed and foolproof guide to moving your iTunes Library, check out this article on iLounge.]
4. Fonts. There is always that font that you used in that PSD that you cannot find anymore and the whole thing just backfires on you. So just backup your fonts before you lose them to the wind. If you’re anything like me, chances are that you have fonts strung about all over your system. The best way is to launch Font Book, select all your fonts, and select Export Fonts.
5. Documents. This is a given. If you have mainly small documents, back them up to the cloud. Otherwise just move all your documents—PSDs, PDFs, Word documents, RTFs and everything in between—to your external drive. A manual copy-paste of your entire Documents folder and whatever other folders you might have created in your Home folder will do (provided you remember to copy them back later, of course).
6. Photoshop brushes, actions, swatches and workspaces. It takes just a few clicks but saving all those will get you a long way, especially if you have customised everything to your liking (dual displays, anyone?). Photoshop, of course, just serves as an example here. You need to backup the settings of whatever other pro apps you might be using as well.
7. Let go of some stuff! There is no point in holding on to a lot of things that do not make sense. Give up your wallpaper collections. Let go of those icons. Wash away all those screensavers that you think are cool but never really use. Starting fresh is a really good feeling.
Now what good is this post without giving a little info on reinstalling as well?
To do that, just pop in your Leopard DVD and double-click “Install Mac OS X” on the Window that comes up. If, for some reason, you cannot boot into OS X at all, reboot your Mac and hold down the C key when you hear the startup chime.
After the setup loads, there are three modes for installation:
Upgrade: You can skip this one. It would be used while, say, upgrading from Tiger to Leopard, where it keeps your files and applications intact, while reinstalling the OS. However, it also keeps some of the cobwebs in place, so I’d say if you want to start fresh, do it right.
Archive and Install: This copies all of the files in your Home folder, including Documents, Movies, Music, etc., into a separate folder and installs a brand new OS. This is really useful if you don’t have an external hard drive to backup all those movies. Your archived folder cannot be used as your normal home folder, all account settings are reset and you have to still manually move all files from the archive to your new Home folder. I’d recommend this process but just make sure that you still do have a backup.
Erase and Install: Erases everything from the partition and installs a brand new OS. Simple as that.
Now, in the following step, along with the Install button, there will also be a Customize button. Going into that will give you an option to deselect all the printer drivers and language files from being installed, effectively saving you somewhere close to 6GB! That’s highly recommended if you have a desktop and are not in constant need of printer drivers (although not having them onboard might result in some Windows-style frantic driver hunting if you decide to buy a new printer someday). Language files should be deselected in all cases (assuming that none of those listed happens to be your mother tongue or one that you’re particularly fluent in). This also speeds up the installation process.
That’s it! After installation, you will get the lovely welcome video and proceed on to a fresh OS, and a happier Mac (notice the wider smile on the Finder icon).
