![]() This week, developer Mykola Grymalyuk showed macOS Ventura running on a 2008 Mac Pro, 2012 Mac mini, 2014 Mac mini, and a 2014 iMac. Some older drivers have also been ported to run on macOS 13. The team was able to run macOS Ventura without AVX2 instruction support thanks to old system files that are still part of the Rosetta 2 technology, which emulates features of an old CPU to run Intel apps on Apple Silicon Macs. Still, the OCLP developers have made some progress. The latest version of macOS, which is yet to be made available to the public, also requires CPUs with the AVX2 instruction set, as well as a new version of Metal that doesn’t work with older GPUs. This includes drivers for non-Force Touch trackpads, Intel Ethernet controllers, Nvidia GPUs, and more. What changes with macOS Ventura?Īs for macOS Ventura, it no longer supports any Macs with Intel CPUs older than the seventh generation, and for this reason, Apple has removed most of the drivers used by these older Macs. ![]() This makes it easier for developers to modify the system to run on Macs no longer supported by Apple. However, macOS Monterey still officially runs on the 2013 Mac Pro and 2014 Mac mini, which are also equipped with older Intel processors. It’s worth noting that tools like this have been around for years, ever since the PowerPC era of Macs.īut how exactly do these tools work, and what’s the challenge with macOS Ventura? The thing is, in the past when Apple discontinued some specific Mac model with a new version of macOS, that version usually still ran on other Macs that shared the same CPU as the discontinued Mac.įor example, macOS Monterey dropped support for most Macs released between 20 that use third- and fourth-generation Intel CPUs. The developers behind OCLP told ArsTechnica that supporting macOS Ventura won’t be easy, but that the team has already “made progress in some crucial areas,” which should allow owners of some older Macs to keep them updated for a bit longer. The tool is based on the same OpenCore bootloader used for Hackintosh, which is a well-known method for running macOS on regular PCs. “ OpenCore Legacy Patcher” (or just OCLP) is a tool that allows older Macs to run macOS Big Sur and Monterey without official support from Apple. However, a group of developers have been working on a tool that will let users run macOS Ventura on unsupported Macs. Feel free to edit it yourself.When Apple announced macOS Ventura in June at WWDC 2022, the company also revealed that multiple older Macs were officially discontinued, including the beloved “trash can” Mac Pro and the very first MacBook Pro with Touch Bar. ![]() If you are not a developer, sign up to the Apple Beta Software Program to get the official public beta releases.Īs requested, this post is now a wiki post.
