I'm selling my old iMac and am going to give away the OS to a mate and so want to delete the OS from the computer before doing so.

I presume installing a new OS should be no trouble (just boot up from the installation disc). Could anyone let me know if this is correct - I wanted to doublecheck before doing it.



2.8 GHz Intel Core 2 Duo iMac, Mac OS X (10.5.4), 2 GB 800 MHz DDR2 SDRAM

    This is correct. Boot from your Mac OS X discs by holding C (or holding the option key, then selecting the disc from the boot manager). Then select an installation type (erase+install, archive+install or upgrade). Just make sure the discs are compatible with your friend's computer. (If it isn't an equivalent model iMac, they should be full retail discs)

    To erase your hard drive, boot form the OS X CDs, then go to disk utility. You can remove data with added security by using the zero out feature too.
