關於古早Mac Pro顯示卡及OS升級問題

朋友接收了一台2006版Mac Pro想更新到最新的OSX，
結果發現原來的7300 GT無法升級到Mountain Lion.
我本來想把閒置的Titan給他拿去玩，結果又發現耗電可能是個問題.

按照Apple官網的說法好像能升級到新版OSX的顯示卡最低等級至少是Radeon 5770.
那請問他可以隨便買張5770以上的卡嗎? 還是一定要買Mac Edition?
他現在看eBay好像任何卡只要標註Mac Edition就至少貴三倍.

您看看這個討論，
可以試試一般的Nivida顯卡+Cuda Driver，
但是要修改OS X的KEXT files，
不確定一定可以成功就是了：

注意這幾個步驟：

PREPARATION

Step 1 (Note: eGPU setup should be all disconnected)

Download and Install CUDA driver http://tinyurl.com/dxzoaww

Step 2

Download and install a modded NVIDIA Web driver
Usually, NVIDIA's official Web driver will do a system check. Official web driver can only be installed on MacPro 2008, 2009, 2010. If you are using a iMac or Mac Mini or MacBook Pro, you can't even install. But Modified Web driver avoids the system check. Modded Web driver file name is ModdedWebDriver-334.01.02f02.pkg.

Step 3

Modify the following KEXT files from your Terminal and look for sections beginning with CFBundleIdentifier and add just before , the two following lines

KEXT Files
/System/Library/Extensions/NVDAStartup.kext
/System/Library/Extensions/IONDRVSupport.kext
/System/Library/Extensions/AppleHDA.kext/Contents/PlugIns/AppleHDAController.kext

Every time you upgrade your OS you need to modify these KEXT files
Finally, clear the cache by issuing the following commandsudo kextcache -system-caches and shutdown your OS.
Warning: The following procedure at your own risk. Please be sure to take a backup in case of emergency.
