carlocav Posted October 26, 2014 Share Posted October 26, 2014 I have a Dell XPS 8000 (quad core-8thread i7 860 2.8Ghz, nVidia GTS 240 1GB, 6GB RAM) without AHCI mode so I am able to install OS X only with the AppleAHCIport.kext Is a computer without AHCI mode slower than a computer with it? I have the possibility to replace it with a less powerful PC that support AHCI Mode. This PC is a Dell Inspiron 580mt (quad core-4 thread i5 750 2.66Ghz, Nvidia GeForce G350 512MB, 6GB RAM). Should I replace my PC with the slower but AHCI compatible one? Link to comment Share on other sites More sharing options...
uglyJoe Posted October 27, 2014 Share Posted October 27, 2014 For my understanding, the modified AppleAHCIport.kext puts your controller into AHCI mode although ide or raid is activated in bios. A search for 'AHCI' in IORegistryExplorer should confirm this. Link to comment Share on other sites More sharing options...

So you need an other way to activate it. Then it will work as good as possible, without drawback. Maybe it will help: http://www.projectosx.com/forum/index.php?showtopic=1150 Link to comment Share on other sites More sharing options...
