You’d think Apple might have learned a thing or two about product name confusion with the Power Book G3/Power Book G3 Series situation, but that isn’t the case.The Revision 2 B&W G3 uses a different motherboard, has an additional drive bracket, incorporates a new IDE controller chip (marked 402) that supports UDMA-33, and includes a faster version of the ATI Rage 128 video card.You can purchase OS X Snow Leopard from the Apple Online Store. Requires a Multi-Touch trackpad, Force Touch trackpad, Magic Trackpad, or Magic Mouse.Requires a broadband Internet connection and microphone (built-in or external). Force Touch gestures require a Force Touch trackpad. With an entirely new minitower case design and huge graphics on the side, this Mac would stand out even without the bright color.
The Revision 1 board isn’t stable with many modern hard drives on the built-in IDE bus because the controller doesn’t support UDMA (Mac OS X does an end run around this problem by disabling UDMA on the Rev. A common suggestion in the old days was to put the hard drive on the 16.7 MBps ATA-3 bus used by the optical drive, but the Rev.The addition of 400 Mbps Fire Wire provides a fast alternative to the missing SCSI.(SCSI PCI cards are readily available, allowing access to SCSI hardware.) Although this model has Fire Wire and USB ports (see Apple Knowledge Base Article #58430, USB Info and Benefits of Dual-Channel USB), it cannot boot from either.Also, it does not support Fire Wire Target Disk Mode.Unfortunately, the Blue & White Power Macintosh G3 shares the same product name as the earlier, very different Beige Power Macintosh G3.Although this model doesn’t support drives larger than 128 GB on its main 33 MHz drive bus, the 16.7 MHz bus used for the optical drive supports multi-word DMA 2 and may support larger hard drive.There are so many reasons to upgrade to mac OS High Sierra now.Supported by the following Mac models: Requires Mac Book Pro with Touch Bar, i Phone 6 or later with i OS 10 or later, or an Apple Watch with watch OS 3 or later.Requires an i Phone with i OS 8 or later and an activated carrier plan.And refinements to the features and apps you use every day.
