WaldMeister Posted August 5, 2015 Share Posted August 5, 2015 Hi, When using MacIASL and ACPI 5.0 i see only warnings, no errors, so you should be able to apply the patches needed for your system. What bootloader are you using, and why can't you boot in to Yosemite? (What error) Link to comment Share on other sites More sharing options...

spakk Posted August 9, 2015 Share Posted August 9, 2015 and now works correctly with the your system? I have found no errors, but you can still review the warnings as an example .... I have checked only the first warning. 2095 Warning ResourceTag Larger Than Field (Tag: 64 bits field: 32 bits) for example: Replace CreateDWordField (BUF0, \ _SB.PCI0._Y0F._LEN, MSLN) with CreateQWordField (BUF0, \ _SB.PCI0._Y0F._LEN, MSLN) and so on .... 2 Link to comment Share on other sites More sharing options...
WaldMeister Posted August 9, 2015 Share Posted August 9, 2015 In addition: Result is not used, possible operator timeout will be missed: If (\_SB.WOL2) { If (\_SB.PCI0.LPCB.EC0.ECOK) { Acquire (\_SB.PCI0.LPCB.EC0.MUT0, 0x0500) Store (One, \_SB.PCI0.LPCB.EC0.WLAN) Release (\_SB.PCI0.LPCB.EC0.MUT0) } } To: If (\_SB.WOL2) { If (\_SB.PCI0.LPCB.EC0.ECOK) { Store (One, \_SB.PCI0.LPCB.EC0.WLAN) } } No need to call something to drop it right after. 1 Link to comment Share on other sites More sharing options...
