OS X 10.7 through 10.9 require OpenPartitionDxe.efi to boot the Recovery partition.OS X 10.8 and newer require EFI64 (i.e.OS X 10.4.8 through 10.7.5 support both EFI32 and EFI64.To resolve this, see here: MouSSE: SSE4.2 emulation (opens new window) Newer AMD drivers also require SSE4.2 for Metal support.SSE4.1 CPUs are supported with telemetrap.kext (opens new window).SSE4.2 is required for macOS 10.14 and newer.SSE4 is required for macOS 10.12 and newer.certain 64-bit Pentiums), we recommend running 32-bit userspace ( i386-user32) SSSE3 is required for all 64-bit versions of OS X/macOS.SSE3 is required for all Intel versions of OS X/macOS.64-bit CPUs are supported from 10.4.1 to current.Note that 10.7.x requires 64-bit userspace, limiting 32-bit CPUs to 10.6.Note not all features of macOS are supported with AMD, see belowįor more in-depth information, see here: Anti-Hardware Buyers Guide (opens new window) CPU Requirements.AMD's Desktop Bulldozer (15h), Jaguar (16h) and Ryzen (17h) CPUs.Note that Mobile Atoms, Celeron and Pentium CPUs are not supported.Arrandale through Ice Lake are supported by this guide.Intel's Core "i" and Xeon series laptop CPUs.Nehalem through Cascade Lake X are supported by this guide.Intel's High-End Desktops and Server CPUs.Yonah through Comet Lake are supported by this guide.This however requires the OS to support your architecture, see CPU Requirements section below.Overall guide on what to avoid and what pitfalls your hardware may hit.įor CPU support, we have the following breakdown:.
Anti-Hardware Buyers Guide (opens new window).Wireless Buyers Guide (opens new window).Check if your GPU is supported and which macOS version you can run.Getting started with ACPI (opens new window)Īnd for more detailed guides on the subject, see here:.If was making that purchase today I might go for a 2017 iMac instead. At the time I was unimpressed that the 2015 21.5"/4K machines only had iGPUs. At worse your GPU choice might not work at all leaving wasted time and effort.įor what its worth when I've been using an eGPU with a 21.5" 2011 iMac (6770M) since late 2016. Option C: Follow the example of the 27" 2011 owners with bad 6790Ms and physically disassemble the iMac to replace the old gpu with a metal capable MXM GPU. Since 2011 iMacs lack Apple's official eGPU blessing you will need to disable System Integrity Protection and make kext edits. The simplest, most future proof, and only option with official Apple support. So, ranked from lowest to highest risk (and highest to lowest expense) That isn't to say you can't but rather a warning that you would be dabbling in hackintosh territory where every MacOS upgrade risks needing system reconfiguration or a broken setup. Apple does not support GPU upgrades on 2011 iMacs.
