But given the progress that has been made so far, it seems likely that people with 2012-and-newer Macs should still be able to run Ventura on their Macs without giving up graphics acceleration or other important features.Flagstaff yard salesWith our free garage sale map, you not only can see at-a-glance where the garage sale hot spots are, you can print turn-by-turn directions to the garage sales of your choice. Grymalyuk still won't speculate about a timeframe for official Ventura support in OCLP. The OCLP team still has other challenges to surmount, not least of which will involve automating all of these hacks so that users without a deep technical understanding of macOS's underpinnings can continue to set up and use the bootloader. By extracting and installing those files in Ventura, you can re-enable support on Ivy Bridge and older CPUs without AVX2 instructions.Īnd this week, Grymalyuk showed off another breakthrough: working graphics support on old Metal-capable Macs, including machines as old as the 2014 5K iMac, the 2012 Mac mini, and even the 2008 cheese grater-style Mac Pro tower. First, while macOS doesn't technically include system files for pre-AVX2 Intel CPUs, Apple's Rosetta 2 software does still include those files, since Rosetta 2 emulates the capabilities of a pre-AVX2 x86 CPU. "Best time frame would be 6 months from now when a proper build of OpenCore Legacy Patcher can be released, but even this is difficult to promise."īut progress has been made, despite that initial pessimism. "Looking at all the issues in front of us, I don't believe there's any short-term possible fixes for the community to use," wrote project lead Mykola Grymalyuk in June. That Github post is a bit downbeat about the future of Ventura support on those older machines. This includes my early 2008 Mac Pro (Nvidia Kepler and AMD GCN 1), 2012 Mac mini, 2014 Mac mini and 2014 5k iMac! /cMQ5Qk8uoo- Mykola Grymalyuk August 22, 2022 But because Monterey continued to support the Ivy Bridge-powered 2013 Mac Pro and the Haswell-powered 2014 Mac mini, the OS still retained some baseline level of support for those processors (and accompanying GPU and chipset hardware) that made it easier to get Monterey running on other Macs with the same chips.Īfter many months of work, we’ve finally gotten macOS Ventura running on legacy Metal GPUs! In macOS Monterey, for example, Apple had officially dropped support for a whole lot of 2012, 2013, and 2014-era Mac models that used Intel's 3rd-generation (Ivy Bridge) and 4th-generation (Haswell) CPUs. OCLP and the dosdude1 patchers could usually lean on some older-but-officially-supported models to extend support to unsupported Macs with similar hardware. But this approach has gotten more difficult as Apple removes more and more Intel Mac support from macOS. In some past years, the hardware differences between "supported" and "unsupported" Macs could be so small that the only thing you'd need to do to boot new macOS versions is trick the bootloader into thinking it was running on a slightly newer Mac. The OCLP developers have admitted that macOS Ventura support will be tough, but they've made progress in some crucial areas that should keep some older Macs kicking for a little bit longer. It's an offshoot of the OpenCore Hackintosh bootloader, and it's updated fairly frequently with new features and fixes and compatibility for newer macOS versions. Tools like XPostFacto and LeopardAssist could help old PowerPC Macs run newer versions of Mac OS X, a tradition kept alive in the modern era by dosdude1's patchers for Sierra, High Sierra, Mojave, and Catalina.įor Big Sur and Monterey, the OpenCore Legacy Patcher (OCLP for short) is the best way to get new macOS versions running on old Macs. Skirting the official macOS system requirements to run new versions of the software on old, unsupported Macs has a rich history.
