Mac mini mid 2007 processor upgrade
This great website has hundreds of beautifully detailed guides for repairing all sorts of computers, gadgets, and other electronics, including the one we needed for our iMac. These guides are so good that, during my time as an Apple technician, we frequently relied on the iFixit Guides over the Apple internal repair documentation. Overall, the upgrade took about one hour from start to finish.

Experienced computer technicians will likely be able to do it even faster. We put everything back together, buttoned the system up, held our breath, and pressed the power switch. After a brief pause, the familiar Mac startup chime sounded and the iMac booted right up.

To check the status of the upgrade, we headed to the System Profiler. Sure enough, our Mac reported a 2. Now we had to deal with the RAM. Basically, it takes the firmware from the late Core 2 Duo iMac and applies it to our early Core Duo system. The Macs were practically identical except for the platform switch to the Core 2 Duo CPU, so the firmware upgrade works beautifully. The app will create a RAM disk to prep the firmware files and then give you instructions on how to apply the update, which involves restarting the Mac and then holding the power button until the status light blinks.
The update takes about 3 minutes and worked without a hitch on our system. It was time to deal with the software problem. Our iMac originally shipped with OS X Officially, A Snow Leopard system, updated and running the Google Chrome browser, would likely meet our needs just fine. So we dug up our old Snow Leopard installer, upgraded the OS, and then performed all necessary software updates to bring the system up to Some quick testing confirmed our initial predictions. Our initial testing revealed noticeable improvements in performance; the system booted faster, apps launched in a flash, and everything seemed significantly smoother.
We anticipated the need to quantify these changes, so we ran benchmarks both before and after the upgrade. The SSD obviously helps with items like application launches and boots. Pure read and write speeds also saw an unsurprising bump. Write speeds were percent faster with the SSD, while reads were percent faster.
Note that this is only a comparison of the specific original hard drive in our iMac with the new SSD. The Mac mini G4 uses a single 2. Because of its sealed enclosure, it is not possible to upgrade the hard drive without opening the enclosure and possibly voiding the warranty of the system. The original Mac mini includes two USB 2. The modem was later omitted from the Mac mini, but an external modem remained an option. External displays are supported via a DVI port. In the last revision of the Mac mini G4, the internal mezzanine board was upgraded to accommodate the AirPort Wi-Fi and Bluetooth technology onto one chip.
In prior models, the Mac mini included an AirPort Extreme card taped to the mezzanine board and a separate Bluetooth module.

The current [ clarification needed ] non-server Mac mini is available in two versions, one with a mobile dual-core bit Intel Core i5 processor that runs at 2. The and Mac mini models that come standard with a bit Intel Core Solo processor can be changed to an Intel bit Core 2 Duo processor through a simple upgrade.
The following processors are compatible: 2. The more recent and later Mac mini models have the processors soldered onto the logic board and thus are not upgradable.
Geekbench scores have shown that the 2. While the Mac mini G4 contained a separate graphics processor, all revisions of the Intel-based Mac mini contain integrated GPUs, except in the version where the 2. Unlike the Mac mini G4, the Intel-based Mac mini uses a dual-channel architecture for memory. While all versions of the Mac mini up to and including the revision supports user upgradeable memory after purchase, the model does not,  because the memory is soldered to the logic board.
Since the integrated graphics processor does not have its own dedicated memory, the system shares some of the main system memory with it. All models continue to use 2.
Stayin’ Alive: Upgrading the CPU, Hard Drive, and RAM on a 2006 iMac
A Combo drive was initially offered as standard, with the SuperDrive being an option, but through the models, all models that have an optical drive contain the SuperDrive as standard. Networking is supported with a built-in Gigabit Ethernet port and an integrated Bluetooth was also made standard.
External displays are supported through a DVI port. A fifth USB 2. The AirPort card was upgraded to Bluetooth was also upgraded from 2. As of this revision, the Apple Remote is no longer included with the Mac mini. The Mac mini model gave access to 3 different USB busses on the back. Upgradable up to an Intel Core 2 Duo 2. Starting from the mid revision, there is a removable panel on the bottom, enabling the user to upgrade the RAM. The new Mac mini has an all-aluminium enclosure, called unibody. The unibody manufacturing process was originally developed for the MacBook Air  and later also used in the MacBook and MacBook Pro , and the iMac before being introduced into the Mac mini range.
The built-in power supply negates the need for an external power supply "brick" used on earlier models. There have been other changes in the revision. They include the elimination of the Kensington Security Slot ,  as well as the optical drive. While the fifth USB 2. Mac mini models released in late used dual-core processors, which perform worse in multi-threaded workloads compared to the quad-core processors from the model.
Meanwhile, single-threaded workload performance increased. PCIe-based flash storage is standard with no option of a hard disk drive. The chassis is mostly a carryover from the previous generation, measuring the same dimensions, though is only available in a darker "space gray" finish. Memory can again be replaced, unlike the models that soldered it to the logic board.

Apple has offered a Server configuration of the Mac mini. Later on, Apple released the OS X Server packaged app as a single purchase from the Mac App Store , containing all the separate components apps, so that any model of Mac computer could download and use them.
The Mid Server model was initially the only Mac mini to entirely remove the optical drive, replacing it with a second hard drive in its place. However, from the Mid models onwards, all models of Mac mini had the optical drive removed. The Mac mini Server hardware was discontinued with the Late model.
Apple states that customers are able to receive support for these services directly from open-source providers. Other Apple-proprietary services, such as Airport, Calendar, Contacts, Messages, and Netboot were also removed, with no corresponding open source options. Alternatives for Mac users include running Linux or Windows virtualized, or installing third-party Unix packages via open source package managers such as Conda, Fink, Homebrew, MacPorts, Nix, pkgsrc, and Rudix .
