Seeing as Tiger has been "announced" according to Logik, time for a reminder on what to do before you actually install Tiger! WARNING! If you are upgrading an iMac G3 to OS X you MUST apply a firmware update first! Otherwise your screen will go BLACK! Thanks to Ed H for finding this linkety 1. Repair your Permissions. This will make sure that after your installation you won't have issues with anything. Of course, this is a bigger issue with an Archive and Install... but anyways... Repairing your permissions will mean that when you are done installing, you will not have any problems opening folders, etc. Oh, and any line starting with "We are using special permissions..." is OK. You do this from the "Applications/Utilities/Disk Utility" application. A nice guide is found here: linkety 2. Repair your hard drive. Start off of the Jaguar, Panther, or Tiger disk and go to the Installer menu->Disk Utility. Choose your hard drive(s) and then Repair Disk. Do this on all of your internal drives (if you have many) until you get the message "The drive Macintosh HD appears to be OK" or similar. 3. Back up your data! Though you rarely hear about an OS X install destroying a drive, you should still back up your hard disk. Or at least your important stuff. 4. Shut down the computer. Unplug all FireWire, USB, etc. devices except for your mouse and keyboard. This way those devices will not be corrupted by the installer and will not corrupt the installation. Those of you with a BT keyboard and mouse may want to stick with your USB one for now, or just turn off other BT devices so you don't have any conflicts. 5. Most people can do an Archive and Install. This is where the old OS X system is moved to a folder in the root level of the hard drive called "Previous System" and the new System is installed. Most settings, etc. are copied over. Remember to check the "Copy over Users and Settings" checkbox (or something to that effect). That way your old data is in its place. If you don't, just remember: Don't Panic!. Your old data is in that Previous System folder. Delete it after a couple of weeks of not using it... that way you regain your hard drive space. That should keep most of the issues that come about from installations from happening. And remember... only 17 days (or less) until Tiger!
