MAC Mini (1.66 GHz Intel Duo, 512 MB 667 RAM) System update URGENT >> SYSTEM SOFTWARE DOWNLOAD LINK on the apple website to be found? I looked everywhere, only updates no full versions anywhere??

OS X 10.5 is not downloadable. It must be purchased on a DVD.

Since the 10.5 DVD are expensive now that Apple stop selling them, it might be better for you to upgrade your RAM to 1GB and order the 10.6 DVD from Apple instead.

$260 on amazon for a 10.5 DVD

or

$469.00 for a Refurbished Mac mini 2.3GHz dual-core Intel Core i5

Just buy Snow Leopard for $19.99 from Apple Store:

OS 10.6 Snow Leopard System requirements

To upgrade to Snow Leopard or install Snow Leopard for the first time, you must have a Mac with:

 An Intel processor

 An internal or external DVD drive, or DVD or CD Sharing

 At least 1 GB of RAM (additional RAM is recommended)

 A built-in display or a display connected to an Apple-supplied video card supported by your computer

 At least 5 GB of disk space available, or 7 GB of disk space if you install the developer tools

You certainly don't sound like a long time Apple customer with the little you know about them. For starters it is only the recent release of Lion that downloading of any of their operting system has been possible. Why is it Apple who is causing you problem is you can't increase your RAM or purchase a DVD. That sounds like your problem not Apple's.

Orginally you said you needed to upgrade the operating system for CS5 now you are saying you have graphics problems. It sounds like you have ignoredthings until everything is dying and then are blaming that on Apple.

You have been given the solution if you don't like it don't blame Apple. It is your problem.

Your Mini's RAM can be upgraded to 2gb

Nowadays that's only $30-40 for the RAM. A bit more if you need someone to do it for you

10.6 is $20

You should be able to do all that Monday morning
