You should verify your chipset and update your profile/signature.
Please provide complete details in your profile.
System: manufacturer/model
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution
For example, typical Ivy laptop:
System: HP ProBook 4540s
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768
Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx). For a laptop, these details are important and affect critical installation procedures.
RehabMan,
System: Lenovo T420s
CPU: i5-2540m/QM67
Graphics: HD3000, 1600x900
I still have some questions, since I am real new on using DSDT Edit etc..
I am using Google to download the MaciASL from SourceForge already, and unzip it. Then run it.
I am running in on my other Hackintosh it is GigaByte EP35-DS3R motherboard...
I am wonder, do I doing right? Since it auto see a System DSDT ... it look like the EP35-DS3R motherboard not the T420s or something like that ....
I am following your link add the this in MaciASL then quit it and reopen it. Look no different,
o add these patches to MaciASL as a repository:
- Run MaciASL
- choose Preferences from the MaciASL menu bar
- select Sources
- click the [+] button
- give it a name (eg. "Laptop Patches")
- type the following URL:
http://raw.github.com/RehabMan/Laptop-DSDT-Patch/master
I still see the System DSDT .... and press the "Compile," I see error
222, 1081, Reserved method must return a value (Integer/Package required for _WAK)
285, 4051, Method local variable is not initialized (Local0)
290, 4051, Method local variable is not initialized (Local0)
Then .. I am lost on this, if I can't boot my T420s, how do I take it DSDT (Like the attachment image, USB installer stop at there, I still not install the OS X in T420s yet)? OR More detail how to or example as a reference on DSDT URL like my case?
Thank you of your help and valueable time.
