The next time you start up your Mac, hold down the Option key while you press the power button. This will take you to a screen where you can choose which operating system you want to load – 10.6 or 10.7. Next time you need to run a PowerPC application, boot into Snow Leopard and you’re good to go.
20. July 2011: With the release of Mac OS X 10.7 Lion, Apple officially ends support for PowerPC-based software. August 7, 2011: PowerPC hardware reaches “vintage” status after being discontinued five years earlier, ending most of Apple’s service and parts support for PowerPC hardware.
Its use in 7th generation video game consoles and embedded applications has had a number of uses, including satellites and the Curiosity and Perseverance rovers on Mars. In addition, PowerPC CPUs are still used in AmigaOne and AmigaOS 4 third-party PCs.
Therefore, OS X supported PowerPC up to and including version 10.5 (Leopard).
Answer: Click the apple in the top left and go to About This Mac. If you can see the type of your processor on the line that says “Processor”. If it contains the word “Intel” then your Mac is Intel-based (see example screenshot), otherwise you have a PowerPC processor.
The first PowerPC Macs were released on 14. Introduced in March 1994, and the PowerPC proved worthy – Apple continued to release new PowerPC Macs until late 2005, just months before the move to Intel began.
Apple uses memory designed to handle both large amounts of data and very fast. It is called “low latency and high throughput”. This eliminates the need to have two different memory types and copying data between them, making the M1 faster.
PowerPC failed because of the hubris of its vendors. They figured because their CPUs were based on high-end server parts that everyone would jump on the bandwagon without having to invest heavily in them. Everyone also thought x86 was nearing its EOL and RISC was the future.
“IBM had to charge more because it didn’t have Intel’s economies of scale, but Apple didn’t want to pay more even though it supposedly benefited more from an inherently superior RISC design, as reflected in the PowerPC architecture manifested.”
Update on x86 and PowerPC CPUs
The recently announced PowerPC 970 currently runs at up to 2 GHz and delivers performance on par with x86 CPUs.
Macintosh computer with a PowerPC G3, G4, or G5 processor. Built-in FireWire. DVD drive for installation.
The 10.4. 11 update is recommended for all users using Mac OS X Tiger and contains general operating system fixes that improve the stability, compatibility and security of your Mac. This update also includes Safari 3, the latest version of Apple’s web browser.

PPC Macs refers to the generation of Macintosh computers developed from the mid to late 1990s to 2006 that used PowerPC RISC-based chips from IBM or Motorola. The last PowerPC-based Macintosh, the PowerMac G5, went out of sale in August 2006.
System 7.1.2 – Mac OS X 10.5.8. PowerPC (short for Performance Optimization With Enhanced RISC – Performance Computing, sometimes abbreviated as “PPC”) is a RISC architecture developed in 1991 by the Apple-IBM-Motorola Alliance, also known as aim.
PowerPC is a power-based architecture whose key feature is RISC (Reduced Instruction Set Computing). While Intel processors are primarily Nehalem-based architectures, their main feature is Quick Path Interconnect (QPI) technology.
“We still have some great PowerPC products to come,” Jobs reiterated during the 2005 transition announcement. After a series of other updates, the Power Mac G5 Dual-Core was the last PowerPC Mac , which has been published.
During this transition period, Apple will support both Intel Macs and Apple Silicon Macs with new features and software updates before eventually phasing out Intel Mac support to move on to newer, faster models with own concentrate chips.
Since a December 2020 Bloomberg report said Apple will divest itself of Intel by the end of 2022 – a move that has been a long time coming – the latter has launched blatant attacks on the former’s partners .
