When Apple decides to finish replace support in your Mac, you possibly can both strive to set up one other OS or you possibly can trick macOS into putting in in your {hardware} anyway. That’s all the level of the OpenCore Legacy Patcher, a community-driven project that helps previous Macs by combining some repurposed Hackintosh tasks with older system recordsdata extracted from previous macOS variations.
Yesterday, the OCLP workforce introduced model 1.0.0 of the software program, the primary to formally support the lately launched macOS 14 Sonoma. Although Sonoma formally helps Macs launched principally in 2018 or later, the OCLP project will permit Sonoma to set up on Macs that return to fashions launched in 2007 and 2008, enabling them to sustain with a minimum of a few of the new options and safety patches baked into the newest launch.
But OCLP helps some Macs higher than others, and usually, the older your Mac is, the extra issues you’ll have.
A key dividing line is between Macs that support the Metal graphics API and Macs that do not—Macs made in 2012 or later usually have it, however these made earlier than 2012 usually do not. Some graphics options are damaged just about throughout the board on older Macs, even ones that do have Metal GPUs—taking part in DRM-protected video in Safari, utilizing Live Text OCR, and enabling Continuity Camera are all listed as non- or semi-functional on the project’s support web page. However, non-Metal GPUs can have much more vital issues rendering fundamental macOS UI parts or operating sure apps.
OCLP has solely had restricted success supporting Apple’s T1 chip, a proto-Apple Silicon coprocessor included in Touch Bar MacEbook Pros in 2016 and 2017. The T1 is much less succesful than the later Apple T2, which handles media encoding and decoding, provides an SSD controller, and handles storage encryption. But the T1 nonetheless does a lot, together with show output for the Touch Bar, Touch ID fingerprint storage and authentication, and Apple Pay support.

Last 12 months’s macOS Ventura nonetheless supported some T1 Macs, so support for it remained baked into the OS. But Sonoma now not natively helps any T1 Macs, so Apple eliminated the system recordsdata used to make it work. The OCLP workforce has had restricted success utilizing older system recordsdata to get it working once more, however doing this additionally breaks Apple ID login on these Macs, affecting an excellent longer listing of options.
Problems supporting proprietary chips in late-model Intel Macs have additionally hampered Linux support on these machines, as detailed in our macOS Sonoma overview. Components like webcams and trackpads are sometimes partially practical or non-functional in Linux on these programs, both due to a scarcity of drivers or as a result of these elements join to the remainder of the Mac utilizing non-standard interfaces.
Still, compatibility points or not, the OCLP project is a powerful endeavor that may permit extra technically savvy customers to squeeze a number of extra years out of an getting old however in any other case practical Mac that Apple now not helps. Even putting in a considerably older macOS model like 2022’s Ventura or 2021’s Monterey will get you safety patches and Safari updates quite than leaving your system unprotected.
