Oct 06, 2020 It takes time to download and install OS X, so make sure that you have a reliable Internet connection. If you're using a Mac notebook computer, plug it into AC power. Download OS X Yosemite. Nov 19, 2002 since no separate OS 9 CD comes with the new Mac OS X installion discs. You are wrong yet you are not wrong. The old way you would get your CD that said MAC OS 9.X whatever on the CD. It doesn't work that way anymore. OS 9 is included on the Software Restore CD's. The only way to install it is in OS X using the Software Restore application. All versions of Mac OS X that were made to run on PowerPC systems (with the exception of Leopard) had a Mac OS 9 emulation layer called 'Classic'. It allowed Mac OS X to run Mac OS 9 applications that weren't updated to run natively on OS X (known as carbonization based on the Carbon API).
My parents ordered an eMac which came pre-installed with 10.1. There was a Jaguar upgrade CD in the box (2 CD:s + Developer Tools). The Upgrade Installer won't let me do a clean install, ie. if I reformat the drive during installation with Disc Utility, it won't let me install. The Upgrade CD 1 is well over 600 MB in size, so is it safe to assume that this is the same situation as with the 10.1 upgrade CD. If I make a copy of the disc and remove the 'CheckForOSX'-file, will it work? I'd very much like to make a clean install, as I have heard this could be beneficial.
