Hardware suportado:

“Mac OS X Server supports all Power Macintosh G3 or Macintosh Server G3 systems, and is optimized for Apple’s new line of Power Macintosh G3s. Mac OS X Server requires 64MB of RAM, 1GB hard drive and a CD-ROM drive. Mac OS X Server is expected to ship the first quarter of 1999 in the United States, with worldwide availability in Spring 1999.” —Apple Computers

“Mac OS X Server will also be available pre-configured on a Power Macintosh Server G3 for U.S. $4,999. This system includes: PowerPC G3 at 400MHz and 1MB level 2 backside cache; 256MB DRAM; ATI RAGE 128 with 16MB Video SDRAM; 2 x 9GB Ultra 2 SCSI 10,000rpm hard drives; 24x-speed CD-ROM drive (maximum); USB; and, 10/100BASE-T Ethernet.” —Apple Computers

In January of 1997, Apple computers promised that their operating system code named “Rhapsody” would run on all computer models that they were shipping at that time and any computer models they introduced after that date, as well as on some unspecified number of Intel Pentium/x86-based computers. As a California corporation, Apple Computers comes under California consumer protection laws and that promise is legally considered an “inducement to buy”. At that time, Apple had not yet started shipping any G3-based computers. Under California law, everyone in the entire world who purchased an Apple Macintosh after that announcement is entitled to sue in California courts for recovery of damages (the cost of the computer and any accessories or software put on that computer) and punitive damages. As a result, this announcement means that Apple Computers has been giving away their non-G3 computers for free since 1997! Not only can customers of non-G3 Macintoshes recover the entire costs of their Macintosh computer systems (the computer, peripherals, software, training, anything that is Macintosh-specific), but they can also receive additional bonus cash! It is possible that those who purchased any competitor’s Intel-based computers may also be able to recover the entire cost of their non-Apple computer systems plus damages if they can show they intended to install Rhapsody on the purchased systems. And owners of G3 computers may also be able to sue, because Apple had promised that Rhapsody would be a desktop operating system, then later changed their plans to make it a server-only OS. This is not legal advice — see your attorney for details.
