If you have a copy of the El Capitan installer from a previous download, you can use something like <http://DiskmakerX.com> to create a bootable USB installer.


Otherwise, we all had to pay for 10.2, 10.3, 10.4, 10.6, 10.7 and 10.8 before Apple started offering macOS as a free upgrade. BUT you need to have the App Store application, and that was not available until you had Snow Leopard 10.6.6 installed, which as explained was a paid upgrade.

1. Clickhere, install the DVD, and run the Software Update pane of System Preferences until it says the computer is up to date.

2. After #1, click here and download El Capitan.

Mac OS X 10.7 and newer don't support PowerPC software such as Microsoft Office 2004. If you upgrade the OS, back up the computer first.

You should be able to buy and install Snow Leopard and then install El Capitan as Niel posted. The computer age isn't a factor.


Check to make sure your applications are compatible. PowerPC applications are no longer supported after 10.6.


Application Compatibility


El Capitan 10.11 Compatibility information




macOS Sierra 10.12: Compatible Apps



Also check to make sure there is a compatible driver for your printer.


Do a backup before installing, preferable 2 backups on 2 different drives.
