![]() ![]() Even more troubles for pre-Haswell Macs.Apple could start shipping x86_64h kernel and kernel extensions.Would kill all pre-Haswell Macs, as Apple would have no reason to maintain x86_64 (non-h) dyld shared caches.Rosetta could potentially be upgraded to support AVX2.0.No Mac in Ventura ships with dedicated EHCI controllers (the last being MacBookAir7,x).USB 2.0 (EHCI) drivers could potentially be removed.Relatively easy patching for models such as MacBookPro14,1.Intel Kaby Lake iGPU drivers should remain supported.Includes cards such as the BCM94350 and BCM94360.IO80211FamilyLegacy-based Wireless Cards should remain supported.With the above discussed, here are my predictions for what we’ll see (or wouldn’t see) in macOS 14 backend-wise that can affect us: Potential Ramifications for OpenCore Legacy Patcherįor those unfamiliar, my colleagues and I maintain the OpenCore Legacy Patcher project which aims to restore support for legacy Macs on newer versions of macOS. Now let’s see what few Intel models we have left: Model With the MacBook Pro family, this would mean the entire 2018+ line survives due to Apple preferring to kill entire families at once instead of odd-ball middle units (see iMac18,1 discussion above, and MacBookPro9,2 in Big Sur). ![]() Otherwise, the 2 machines that I believe are a stretch for drop off:Īs these are both “discontinued in 2020” units, they could legitimately survive. So for Apple to kill iMac18,2/3 but not iMac18,1 would make little sense.
