Apple has extended its scheme to let owners of older Macs upgrade to Mac OS X 10.4 Tiger.

Mac OS X Tiger ships on a DVD. Not all Macs are equipped with DVD players - but are otherwise fully specified to run the new OS.

In recognition of this, Apple launched its Media Exchange Programme.

This scheme lets Mac users who buy DVD Tiger installation discs to swap the DVD for a set of CD installation discs. It costs £11.99 in addition to the cost of the OS.

The scheme was originally scheduled to end on July 9, but Apple has quietly extended it until December 31, 2005.

The UK Mac-Dealer Association last week announced its promotion to install Tiger onto Macs without DVD drives for a fixed price at a selection of dealerships across the UK.

"We believe it was our promotion that helped Apple to realise that they
had ended the CD fulfillment programme about three months too soon",
said Robert Peckham, executive director of the association.

The association intends to continue offering this service.
