Bluetooth 6.0 is the latest iteration of a wireless short-range data exchanging protocol standard, spanning way back to 1998. The latest version was 6.1, from May 7th, 2025. As of August 17th 2025, all of the latest Macs have Bluetooth 5.3. Devices with an M5 chip are likely to be the first crop of Apple […]

When the Dual-Core PowerPC 970MP third-generation G5 CPUs came out in Mid-2005, Apple had to start using a brand new Mid Bridge chip for the Macs along with it. Since the AMD 8131 only had PCI-X bridges and no PCIe bus, they couldn’t keep the old chip, replacing it with the BCM5780. (Above: Block diagram […]
Have you ever wondered why there’s an AMD chip on the back of your Power Mac G5’s logic board, or what it’s even doing there? For higher end Mid-2003 thru Early 2005 Power Mac G5s, that’s the PCI-X “Mid Bridge” chip. This is what handles all your expansion cards! Although, it doesn’t appear in Late-2005 […]
The IBM CPC945 is a redesigned Northbridge chip mostly for the Dual-Core PowerPC 970MP CPU. It has technical upgrades over the IBM CPC925, including a faster HyperTransport Bus. It’s also capable of talking to the PowerPC 970fx second-generation G5 chip, which means it may be found in other Late 2005 Macs on the logic board. […]
The G5 is a 64-bit member of the PowerPC processor family that is fully compatible with 32-bit code. The third generation of G5 chips were first used in the Late-2005 Power Mac G5. These were the very final PowerPC chips ever used in any Mac, and were the only ever Dual-Core PowerPC chips. This chip […]
Metal is the current generation of low-level graphical API that Apple uses, which powers the hardware accelerated graphics on their OSes, namely macOS. Metal 1.0 was introduced on September 30th, 2015, alongside Mac OS X El Capitan and iOS 8. Before the Apple Silicon transition, the Metal API received regular major updates every 2 years. […]
The G5 is a 64-bit member of the PowerPC processor family that is fully compatible with 32-bit code. The second generation of G5 chips were first used in the Mid-2004 Power Mac G5. The design of these were massively updated with strained silicon, with a smaller fabrication size. These chips were also used in the […]
The G5 is a 64-bit member of the PowerPC processor family that is fully compatible with 32-bit code. It was first used when the Power Mac G5 was introduced in June 2003. Only three different versions of the chip were produced before Apple made the move to Intel CPUs in 2006. IBM was the only […]
Whether you’re running a Mac, an iPhone, an iPad, or another sort of Apple device, each device has it’s own operating system which also has a build number. A build number is a unique identifier for a specific version of an OS. Apple cranks out tons of builds of their OSes for employees to test, […]

The HDMI forum just announced a brand new update to the HDMI specification. This includes major upgrades in available bandwidth, screen resolutions, as well as a new HDMI cable feature name called Ultra96. HDMI is now up to version 2.2, up from the previous 2.1b specification from August 2023. Download: HDMI-2-2-Specification-Overview-20250625.pdf.zip (1.8MB) . (Above: Illustration […]
In continuation of the expansion of the Tech Spec article and information index on Low End Mac, all Intel CPUs presumably ever shipped with a Mac have now been added to the tech spec index! This effort involved the creation of over 220 new articles and an unusually long index list page as a result […]

You take the 10th-gen iPad from 2022, give it some iPhone 14 Pro parts, and bam – new iPad. No Apple Intelligence on this model due to system constraints, although it gains an extra 2 GB of RAM from the previous generation like how other Apple devices received a RAM upgrade across the line. Considering […]
During the 16th annual conference hosted by Apple at the Moscone Center in San Francisco, Apple announced the transition to the Intel platform as well as the release of a developer transition kit (DTK). These were the first-ever released Intel computers by Apple, although the commercial debut for the first Intel Mac is at least […]
Back in 2021 roughly half a year after Apple Silicon was released to the consumer market, we got our first iteration of an iPad with a desktop-class CPU in it – the M1 iPad Pro. They chucked an M1 into an iPad Air a year later, and fast forward to 2025 – we now have […]
