hi maldon,
thanks for your help and also for putting all the resources together.
I enabled the patch and installed HS without problem. when I copied your clover775 folder over to my EFI, the option for IO Error patch disappeared, I managed to put it back myself with the I/O binary patches in config.plist.
Then I installed the nvida webdriver, and that was straight forward without issue.
however I have not yet found a solution for the sound to work. my sound-device should be alc1200 (from Asus p5ql-em), and I tried injecting layout-id 1,2,3,5,7,11,12,13 , none of them worked. the only way the computer would boot into HS is if the layout-id is empty, any other number it would end with the error message 'time out with IOHDADEVICE........"
I have also tried fixed option and suggestions from https://hackintosher.com/guides/get-hackintosh-audio-working/ but neither have not worked.
do you have any ideas/suggestions? your help is much appreciated.
many thanks.
