Motorola had added a seventh pipeline stage in the new PowerPC G4 design to achieve faster clock frequencies. The number of RAM slots was reduced to three, accommodating up to 1. At Macworld Expo New York on July 18, , a new line debuted featuring a cosmetically redesigned case known as Quicksilver , and various upgrades to the specifications.

The MHz model was notable for not having a level three cache. Quicksilver received criticism in MacWorld's review for removing the "eject" button and the manual eject pinhole, as well as the pass-through monitor power plug, and for the base specification of MB RAM as being insufficient for running Mac OS X. This was the first Mac to reach 1 GHz. Again, the low end MHz model did not include any level three cache. All models were available in dual processor configurations running at MHz , 1 GHz or 1. A single processor 1. The last real update to the Power Mac G4 line was on January 28, offering dual 1.

Between that, its low price-tag, and the delayed availability of Power Mac G5s, it proved a strong seller for a relatively short time. Production stopped on June 27, and the remaining inventory was liquidated, ending the year legacy of Classic Mac OS support with its discontinuation. A limited range of serial numbers of this model was noted for a noisy fan, earning them the unofficial designation " Windtunnel G4" in some communities.

Noise complaints became such a problem that Apple later replaced the machine's power supply PSU and primary cooling fan with quieter versions, and initiated a voluntary do-it-yourself DIY replacement scheme for all previously sold machines. It is believed [7] that the reason for the problem is a bug in the CPU with handling cache coherency in dual cpu setups when switching the CPU to low power states. In a low power state, each CPU would have only consumed about 5 Watts [9] or even less when switching to even lower power states , making for 10 Watts needing to be cooled. But when run in full power mode as to circumvent the cache problem , each CPU does consume about 50 Watts making for a total of Watts [10] —essentially the upper limit for which the cooling system was designed, making the fans run at full speed, even when the machine is mostly idle.

Soon after suggesting that hack to Apple, a new firmware was released, [15] disabling the API for switching between single and dual CPU modes. At least some MDD models also have a design flaw resulting in noise in the audio-out, picking up interference from the mouse, graphics card, hard drive and other hardware. According to Apple, this is a ground loop issue, and only occurs when used with professional balanced signal audio equipment, [17] however some audio experts contended it is due to shielding defects on the motherboard and affects all equipment. The original Power Mac G4 was introduced at the Also unlike the iMacs, it had a video card in a standard AGP slot.

However, there was not enough space for full-length cards. The Cube is exceptional as the only Mac Apple has applied this name to various though closely related processor models from Freescale, a former part of Motorola. Motorola and Freescale's proper name of this family of processors is PowerPC 74xx. The last desktop model that used the G4 was the Mac Mini which now comes with an Intel processor.

The Po It was built later by Freescale, after Motorola spun off its semiconductor business under that name in The PowerBook G4 has two different designs: Between and , Apple produced the titanium PowerBook G4; between and , the aluminum models were produced. Both models were hailed for their modern design, long battery life, and processing power.

When the aluminum PowerBook G4s were first released in January , inch and inch models were introduced first, whil When introduced, it was the most powerful computer in Apple's Macintosh lineup, and was marketed by the company as the world's first bit desktop computer. Three generations of Power Mac G5 were released before it was discontinued as part of Apple's transition to Intel processors, making way for its replacement, the Mac Pro.

The Mac Pro retained the G5's enclosure design for seven more years, making it among the longest-lived designs in Apple's history. The Power Mac G5, the last model of the series. The Power Macintosh, later Power Mac, is a family of personal computers that were designed, manufactured, and sold by Apple Computer, Inc. Software written for the Motorola and processors that were used in Macintoshes up to that point would not run on the PowerPC natively, so a Mac 68k emulator was included with System 7.

While the emulator provided good compatibility with existing Macintosh software, performance was about one-third slower than comparable Macintosh Quadra machines. Introduced on October 23, , it was promoted by Apple as "The Best Internet Operating System Ever",[2] highlighting Sherlock 2's Internet search capabilities, integration with Apple's free online services known as iTools and improved Open Transport networking.

While Mac OS 9 lacks protected memory and full pre-emptive multitasking,[3] lasting improvements include the introduction of an automated Software Update engine and support for multiple users.

Apple's move to build-to-order sales of the Power Macintosh G3 also coincided with the acquisition of Power Computing Corporation, which had been providing telephone sales of Macintosh clones for more than two years. The Power Macintosh G3 is named for its This list of Macintosh models by case type contains all case designs used by Apple Inc.

The list is sectioned by general case layout, but inside the sections the order is chronological. Models that used multiple names like most Performas are listed only once. Where available, the "form factor" from Apple's datasheets has been used to determine the case designation and the computers that used it. For all-in-one models and notebooks that have the same basic case design, but differ in size, just one type is listed. Also, some models that differ only slightly or internally are listed together, like the two iMac G3s and the Power Mac G4s.
