Yaayooo posted a topic in Hackintosh MavericksThe selected 128 RAM configuration is not supported for the HD4000 Hi there, I already installed the OS X Mevericks on my Acer Laptop. The installation seems to be succesfull but there is a problem when i restart my Laptop and when i really want to use the Mac System now. When i click on my Macintosh Partition, where OS X Mevericks 10.9. is installed i get an error. It says "The selected 128MB RAM configuration is not supported for the HD4000". I don't know how to fix it cause i can not change my video memory in the BIOS, it is an unchangeable value. I have already tried many different Boot Flag combinations but nothing worked. Does anybody know if there is a possibilty to specify the video memory? Or does this mean that my Laptop is incompatible with OS X? Here my technical Laptop specification: - Intel Core i5-3230M -Intel HD 4000 -NVIDIA GeForce 710M with 2GB dedicated VRAM 8GB DDR3 Memory I would be very thankful for hints and helps. I hope anybody can help me. Kind regards!
