[SOLVED] Sierra and/or Clover messing with BIOS

[djneba]

I would like to help, but this was more than two years ago, and I don't remember all of the steps I did. I didn't update my hack since, so I didn't repeat the process more than once either.

Can you wait for a day or two?
I will try to do the process again so I can give you more precise info.

1) Download MaciASL from here:

https://bitbucket.org/RehabMan/os-x-maciasl-patchmatic/downloads/

2) Open MaciASL

3) Go to File > New from ACPI > DSDT

4) You'll get a new window titled "Pre-edited DSDT"

5) Click on Patch, just below the window title

6) On the left scroll down to category "RehabMan Laptop"

7) Inside the category find and click on the entry named "[sys] RTC Fix"

8) Click Apply at the bottom, then Close

9) Go to File > Save As.. , and save your file as DSDT.aml ("ACPI Machine Language binary format" type)

10) Then put the patched DSDT.aml inside EFI/Clover/ACPI/patched

11) Disable all RTC fixes in Clover (if you had any)



WARNING!!!
This may not work. I can't guaranty it will. I did this a long time ago, and I might have forgotten some important step(s). If you decide to go with it, please do so at your own risk. BACKUP YOUR DATA BEFORE PLAYING AROUND.

Good luck!
