I have been given a PowerMac G4 AGP 400Mhz with 10 and 20 gig HD and 768 MB ram. It currently has OS9.2.2 and I want to put 10.3 on it. I found a good deal on a full retail on ebay but on the page the seller wrote this: "If you have a G4 Mac mini and are looking to restore your original software, this is the item for you. No other software is going to install on this computer, not even the Apple retail box CDs. We have the exact item you need. As a bonus, get the most stable and fastest iLife yet (especially suited to G4s), along with Quicken & AppleWorks too! Compatible with any G4 Mac mini. Requires 128 MB of RAM & internal or external DVD, Combo or Super Drive to install. " Another buyer asked this question: "Hi there! The OS X in this item is Mini, but the rest of the software programs (such as AppleWorks, iLife & Quicken) will load on ANY computer. For your Cube, I recommend item # 190298912266, 190298923750 or 190125157366. Or you can get item # 190298844282 if you don't need a printed license & manual. Any of those 4 recommended items will install on your computer (and just about ANY other computer). Once you have bought it, you can request that this item (the one you asked the question on) be added to your order for an additional $9.99. So for a very reasonable price you can have all of the items from this auction install onto your computer If you have any further questions, please don't hesitate to ask using eBay's messaging system or CALL us." This all lead me to believe that this OSX will not work on my G4. But all of my other research tells me that it will work. I don't think that they mad a special osx 10.3 for mac mini's only. I just need to know if I purchase this, will it work?
