stexano Posted April 18, 2016 Share Posted April 18, 2016 Hi everyone, i recently bought a Lenovo Z70-80 broadwell Intel i7 with HD5500 graphics (and disabled nvidia...) for el capitan or even yosemite but i stil can't reach the installer. I am following every guide I find and trying the combinations of drivers, kexts, config.plist etc Is it true that i need to set DVMT-prealloc in BIOS? Without flashing bios i cannot do anything? Here on OSXLatitude i downloaded the zip files but i see no mention of this bios flashing procedure Thanks! Link to comment Share on other sites More sharing options...
ypdeveloper Posted April 18, 2016 Share Posted April 18, 2016 use this config.plist than check Working OSX.rar Link to comment Share on other sites More sharing options...
stexano Posted April 18, 2016 Author Share Posted April 18, 2016 Thank you ypdeveloper: just tried it with my El Capitan 10.11.4 installer, but i keep getting the same OxsApitpFixDrv error: "requested memory exceeds... etc etc". I used also the FakeSMC.kext you provided (i had a newer one...) with OxsApitpFixDrv2 i get the couldn't allocate runtime area error I really wonder how other owners managed to get to the installer on this Lenovo laptop Any further help?

stexano Posted April 18, 2016 Author Share Posted April 18, 2016 Actually it is on slot 2... i can't believe it! I'll swap and report back! Link to comment Share on other sites More sharing options...
stexano Posted April 18, 2016 Author Share Posted April 18, 2016 Nothing new memory stick on slot 1 now still getting the same errors. I use a usb2 pen on usb2 ports (i tried also other combinations with usb3 pen and ports) Ideas? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 18, 2016 Moderators Share Posted April 18, 2016 Use legacy mode in BIOS, and set SAta operations to AHCI Link to comment Share on other sites More sharing options...
stexano Posted April 19, 2016 Author Share Posted April 19, 2016 My clover in Efi partition is EFI only... i guess i have to prepare a new pen, right? Link to comment Share on other sites More sharing options...
dragopas Posted April 19, 2016 Share Posted April 19, 2016 Hello, Stexano if you have a Mac or Hackintosh .... physically disassemble the z70-80 and connect a sata hd door of this. use this procedure: http://www.insanelymac.com/forum/topic/307119-el-capitan-hd/ copies the correct Kext and reconnect on z70-80 and starts you will need to set the bios, and used for the first boot a keyboard and mouse usb ....... But the real problem of Lenovo z70-80 !! even if you disable the video card will work badly because the dedicated memory is set to 128 MB and you can not change 64 .... You have to lead by the bios Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 19, 2016 Moderators Share Posted April 19, 2016 @stexano, Do you mean your EFI partition folder is empty? If so, then just copy the Bootpack (Clover Folder & Boot folder) to it. Link to comment Share on other sites More sharing options...
