Early 2013 iMac (Education)

This version of the Early 2013/Late 2013 iMac is stripped back and only available to educational institutions; it is not available for sale to individuals.

21.5″ Retina 4K iMac (Early 2019)

This was the end of the line for the smaller Intel iMacs altogether, and perhaps you’re thinking: doesn’t this have a T2 security chip since it’s from 2019? Rest assured, it doesn’t. There were no 2020 or 2018 4K iMacs, and this model came with Intel’s 8th gen coffee lake processors, the same generation used […]

21.5″ Retina 4K iMac (Mid-2017)

Although only $200 separated the purchase price of the base model Mid-2017 1080p iMac versus the 4K Mid-2017 iMac, the differences inside couldn’t be more drastic. On the surface and on the outside they look to be the very same machine.. until you start tearing one apart and realize how much more upgradeable the 4K […]

21.5″ 1080p iMac (Mid-2017)

This iMac is basically a giant 13″ 2017 MacBook Pro but with replaceable RAM and no battery.

An introduction and some history A bit over a decade ago, Apple released the 2011 MacBook Pro with the now infamous Radeon 6000 series discrete Graphics Card.

Mini-PCIe, Express34, MXM eGPU compatibility index: Part 1

Certain older Macs are able to take advantage of adding an external graphics card through modification. This usually requires external power, the corresponding adapters, can be done via the mini-PCIe slot or MXM slot, and come with case-by-case caveats as most of this was never intended to be a thing. Once installed and properly connected, […]

Although this topic has been documented elsewhere, it will also be covered on Low End Mac for our readers. While bluetooth and wifi technology have since moved onto newer standards – Bluetooth 5.3 and Wifi 6 respectively, this adapter offers a pop-in replacement where the old AirPort card was. Rather than shoehorning a full-on PCIe […]

Keepin’ the Power Mac G5 running cool: What worked for me

The following is an article about a story of what happened to a LEM group member’s peculiar Power Mac G5, as well as the experiences I had troubleshooting my own.

13″ Intel MacBook Pro, 2 or 4 TB Ports (2020)

Just like the 2019 model year, the 2020 intel model year is differentiated in name by its amount of thunderbolt ports. The awkward naming scheme caused confusion to some, when in reality it was separating the low/higher end 13″ models, like the non-TouchBar models that came before it. The 2020 model year 13″ MacBook Pro […]

13″ MacBook Air (Mid-2017)

This was the very last and final A1466 ‘Book, a design dating back to Mid-2012 with the release of the Ivy Bridge Intel CPUs. The base’s i5 was bumped from 1.6 to 1.8 Ghz, and the i7 option remains the same as what was available in 2015. The ’17 ‘Air comes with 8 GB of […]

12″ Core M MacBook (Early 2015)

On March 9th 2015, Apple reintroduced the MacBook after a 4-year hiatus, becoming the #1 thinnest Mac at the time. Most simply referred to this as “the new MacBook” during its production, before settling into calling it “the 12-inch MacBook”. It wasn’t cheap, starting at a hefty $1299, matching the cost of an entry-level 13″ […]

CustoMac: Gutted 20″ ’06 iMac + eGPU

Nearly 20 years ago, this was a white Late 2006 20″ iMac. Today, it’s fastened to two wooden shelf pieces, supported by a… shelf bracket.

CustoMac: 3.1 Ghz i7-5557u-upgraded 11″ 2015 MacBook Air

The 11″ Early 2015 MacBook Air ships with a 2.2 Ghz i7-5650u as a BTO/CTO option, making it the absolute fastest 11″ ‘Book ever. This hasn’t at all stopped users online from shoehorning an even better CPU in there, which inadvertently or intentionally upgrades the GPU also. Out with the old Intel HD 6000, in […]

Mac OS X Snow Leopard 10.6 – 10.6.8 for PowerPC

The official “De Jure” Mac OS X Snow Leopard was announced at WWDC 2008, released August 28th 2009, and ultimately was never intended to run on PowerPC in the end. For a long time, it was known there were PowerPC-compatible beta builds of OS X Snow Leopard, however, these builds remained seemingly elusive until 2020. […]

14″ MacBook Pro (2021)

I’m getting “heavy” 2009 Aluminum 15″ MacBook Pro vibes off of this. Is it the keyboard, with the return of the scissor switch? Is it the screen real estate, and return of physical buttons as opposed to a Touch Bar? It has rounded edges similar to a TiBook rather than tapered edges of the unibodies.. […]

Mac GPU upgrades: Nvidia GeForce 7800 GT

The Nvidia GeForce 7800 GT was a GPU option available for the Late 2005 Power Mac G5, and was released by Nvidia on August 11th, 2005.

ATI Radeon X850XT vs Nvidia GeForce 6800 Ultra DDL: 20 Years Later

In the world of computer upgrades and peripherals, the age-old question has come up time and time again: do I get this one, or that one?

Fanxiang 1 TB mSata SSD in a Hi-Res 15″ PowerBook G4: So far so good

It’s been nearly a year since the SK 128 GB mSata SSD was taken out in favor of a larger capacity, 1 TB Fanxiang SSD. Since the Hi-Res PowerBook G4 15″ 1.67 isn’t limited to a 128 GB storage drive capacity, it seemed a suitable candidate to take advantage of this upgrade. The largest drive […]

15″ MacBook Pro with 6-core i7/8-core i9 (2019)

Until Apple does otherwise, this was the latest and greatest 15″ ‘Book ever made in terms of specs. In practice, the i9, VRMs, GPU, and other combined upgrades were a bit much for the chassis to handle, exacerbating the chassis’s inability to vent heat out of the computer. The higher the configuration, the more likely […]

Mac mini (2024)

You just might have to do a double-take if you see one of these in person. Coming in at a remarkable 5″ by 5″ by 2″ (12.7/12.7/5.0 cm), the third-generation Apple Silicon-based Mac mini resembles a footprint akin to an Apple TV 4K. This is a brand new design for the Mac mini, the first […]

27″ iMac Pro (Late 2017)

You definitely have to ponder for a minute – what was Apple thinking when making this computer? There’s literally nothing else like it, developed and released at a time when people were unsure of whether or not the Mac Pro would receive an update. The 2013 Mac Pro 6,1 received little to no updates in […]

24″ M4 iMac (2024)

On Monday October 28th 2024, Apple announced the M4 iMac, the first with this most advanced chip. An M4 iPad Pro exists and was released to the general public on May 7th, 2024, being the only other device with an M4 chip at the time. The physical dimensions and design are all the same, but […]

24″ M3 iMac (2023)

Apple gave the iMac a fresh new look in April 2021, the first major iMac redesign in a long, long time.

The new look changes the […]

24″ M1 iMac (2021)

The M1 iMac arrived in the second wave of first generation Apple Silicon Macs, and is the first Mac to receive a redesign alongside the new chip. Gone are the 21.5″ and 27″ screen options of the Intel era, and none to replace the larger option. November 2020 saw the announcement of the M1 Mac […]

Mac Studio (2022)

There was a time in the PowerPC era roughly 20 or so odd years before the Mac Studio’s release, in which Apple sold a rough equivalent to the Studio itself. Perhaps it’s a stretch saying such a thing – however, the Power Mac G4 Cube did offer the same G4 Processor and most of the […]

Mac Pro (2019)

Although the outgoing Mac Pro had a 6 year run, it received few, if any updates during that time. In the weeks, months and years preceding the release of the 2019 Mac Pro, the crescendo of silence surrounding the Mac Pro led many to believe Apple was going to axe this model from the lineup. […]
