I'm trying to upgrade the operating system on my G4 and after downloading OSX 10.4.11 I got a message that it couldn't be installed on my computer. could someone please help me with the steps to make the upgrade successful? Many thanks!
 
Every "point update" to Mac OS X requires that you purchase the new operating system.

For example, you purchase 10.3. Updates to 10.3 are free, and incrementally change the version number to 10.3.1, 10.3.2, etc. 10.3.9 is as high as you can go, because that's the last update Apple released for that operating system.

10.3's successor is 10.4, and is not a free upgrade. You must purchase and install 10.4 in order to be able to upgrade to 10.4.11.

Similarly, 10.5 is not a free upgrade to 10.4, and must also be purchased.

You don't have to upgrade sequentially -- you can go straight from 10.3 to 10.5 if you like, since every "point update" is really just an entirely new operating system.
 
You have to upgrade to 10.4 first. The updater that you downloaded takes you to current version, but you have to install 10.4.x first, using the commercial installer. You'll have to buy that somewhere. Ebay is a good place to look, but make sure you don't get a 10.4 disk that is grey. That will be a model-specific version, which originally came in the box with a new Mac. You want one that's on a black DVD. All the commercial installers will be similar in appearance.

Thanks, I'm obviously pretty stupid at Mac.
Another quick question - when I buy the upgrade and install it ... will I lose everything I have on my Mac today?
 
No, not unless that's what you want to do!
Boot to the installer disk, and continue through the install. The default will be a simple upgrade. Some (including me) would recommend that you choose the Option (at the screen when you select the install drive), to Archive & Install, which will disable your present OS, and install a fresh set of OS software, keeping your user files and other setttings. The process is fairly safe, and you get the upgrade along with very little change in your other software setups.
