Description: Attn:This is not plug and play solution.-- You must know your iMac model and year, your old graphics model, and read the following description carefully, so you know what items you need to buy.-- You may need to modify your old heatsink, and learn how to assemble the card, how to use OpenCore (OC) / OpenCore-Legacy-Patcher (OCLP), how to configure a "config.plist" of OpenCore.-- You also need to know that this is not Apple original graphics, some features do not work, read the "Feature" in the description carefully. If you can't accept the loss of some functionality, go and search for the Apple original graphics.Tested Machines:- iMac 11,1 27 inch A1312 Late 2009(The machine with "Core 2 Duo" processor is iMac 10,1 and can't work, please don't buy)- iMac 11,3 27 inch A1312 Mid 2010- iMac 12,2 27 inch A1312 Mid 2011"Which option should I buy?"iMac 11,1 / 11,3--buy option 3. "Card+Heatsink+X".All original iMac 11.1 / 11.3 have 35W (MXM-A, 2 pipe half-height heatsink) and 50W (MXM-B, 2 pipe heatsink) which can't support K3100M 75W (MXM-B, 3 pipe heatsink). The complete combo option "Card+Heatsink+X" is the only option.iMac 12,2 with HD 6770M -- buy option 3 "Card+Heatsink+X".The original 50W MXM-B 2 pipe heatsink can't support K3100M 75W (MXM-B, 3 pipe heatsink). The complete combo option "Card+Heatsink+X" is the only option.iMac 12,2 with HD 6970M 1GB / 2GB, must buy new X-bracket for MAM-A. The old X-bracket can't fit. choose the option 2 "card+X-bracket".Don't try to modify / cut your old X-bracket, the modded / cut X-bracket will damage the video card. And you must modify the 3 pipe heatsink too. If you can't or don't know how to modify, choose option 3 "card+heatsink+X".If you have X-bracket for MXM-A, a 3 pipe heatsink and you can modify it, you can try to buy option 1 "Card" only.Do NOT buy a "card" only, and then trick an extra X-bracket or modified 3 pipe heatsink by using sorts of excuses or threatenning me with negative feedback or dispute. I won't let you get your way!!!Feature:- Genuine native boot screen and brightness control- Metal Supported- Windows / Bootcamp supported- VDA decoder failed (AirPlay / Apple TV doesn't work)1. iMac 11,1 needs to use external display to boot into MacOS, and run OCLP to build new OC, then internal display can work. So, you need a Thunderbolt / MiniDP to VGA / HDMI / DVI cable / adapter to get external display at beginning. If you don't have the cable, search from my store or contact me for the link.If you get a black screen issue with your iMac 11,1, contact me for the solution first.2. Native boot screen and brightness control in High Sierra, but need to fix the level of brightness.Suggest OCLP (OpenCore-Legacy-Patcher) for High Sierra / Majave / Catalina / Big Sur / Monterey / Ventura / Sonoma. OCLP will fix the level of brightness and provide OpenCore boot picker. Need to post "nVidia Kepler patch", run OCLP and choose the second "Post Install Root Patch".3. GPU Temperature Monitoring is available on, but does not control the fans! Move and fix the ODD sensor (CD-ROM temperature sensor) to the GPU heatsink, and use MacsFanControl to set ODD fan run in "full blast".
