JP Brown posted a topic in Hackintosh YosemiteGood morning. This is my first post here and I have throughly enjoyed my experience with my first Hackintosh. Niresh much love to you. Excellent work my friend. I will be sending some cash your way soon. I am having some small issues with my new install. 1. I have Win7 Pro installed on an SSD as my main OS. However, after installing Yosemite on a separate HDD, I am receiving a "BootMGR missing" error when I select my Win7Pro HDD to boot. I have already tried to repair the master boot record with the Windows install disc without any joy. 2. the AppStore will not let me login with my apple ID. I receive an error message saying that "This computer or device cannot be verified. Please contact support". Did I miss a step here or is there a fix for this issue? 3. Is there a known kext for a nVidia 570GTX? I have experienced some sporadic graphic issues. I have graphics enabler enabled with 1080p display enabled. System Specs: AMD FX 8120 Asus Crosshair V Formula 16 GBs RAM nVidia 570gtx Windows 7 Pro OSX Yosemite 10.10 Any help or advice would be much appreciated! Thank you in advance!
