install disk was gone...need software!

If you call Apple and give them your model number and serial number they will sell you whatever was originally installed on your computer for about $15 a disk. (Usually there are only 1 or 2 disk) According to Mactracker in your case the would be Tiger (10.4). The highest operating system you can use is Leopard (10.5) but if you want that you should purchase a Retail copy. ( Don't use ebay as the sell a lot of machine specific software that might not work for you. Apple will sell you a Retail copy of 10.5.6 for $129 if you want to go that route but I would think you probably would be happy with Tiger and it needs fewer resources. Memory, etc.) If you must order online I will leave you a link to one company. Ralph
