![]() ![]() This stack was responsible for supporting the majority of wireless cards used Macs, including machines up-to iMac18,x. With Sonoma, another big axe has been dropped: Removal of IO80211FamilyLegacy support Currently investigating the cause, but problematic functions are: We have mostly resolved this issue internally, however cannot ship due to complications with IOSurface ABI.Īdditionally we've discovered an ABI change in IOAcceleratorFamily2 that causes kernel panics when engaging with the Intel framebuffer.Currently we've determined UI corruption within IOSurface, which would lead to incorrect rendering of wallpapers and menubar. However it seems this new compiler version hasn't changed the ABI drastically, as GPU's based off of the 31001 compiler are still mostly functional. This compiler is what powers the Metal graphics stack in macOS, and is critical to getting functional acceleration. ![]() With macOS Sonoma, Apple has transitioned to a new LLVM compiler version known as 32023. Graphics support 31001-based Graphics Cards Otherwise graphics is still natively supported. IMac18,3: iMac (Retina 5K, 27-inch, 2017)Ĭurrently the only known limitation with these units is the lack of wireless support.
