Post-install

Generate your own SMBIOS

For setting up the SMBIOS info, use GenSMBIOS

Run GenSMBIOS, pick option 1 for downloading MacSerial and Option 3 for selecting out SMBIOS
- MacBookPro9,2
Open Config.plist, find PlatformInfo >> Generic
- The Serial part gets copied to SystemSerialNumber.
- The Board Serial part gets copied to MLB.
- The SmUUID part gets copied to SystemUUID.

Reminder that you want either an invalid serial or valid serial numbers but those not in use, you want to get a message back like: "Invalid Serial" or "Purchase Date not Validated" Apple Check Coverage

CPU power management

Recommended additional steps to improve battery life with optimized CPU power management:

Open Config.plist, enable ACPI>>Delete : Drop CpuPm and Drop Cpu0Ist

Open Terminal, copy and paste the following command:

curl -o ~/ssdtPRGen.sh https://raw.githubusercontent.com/Piker-Alpha/ssdtPRGen.sh/master/ssdtPRGen.sh
chmod +x ~/ssdtPRGen.sh
./ssdtPRGen.sh

A customized SSDT.aml for your specific machine will now be in the directory /Users/yourusername/Library/ssdtPRGen
Rename to SSDT-PM.aml , and copy to EFI/OC/ACPI/
Open Config.plist, enable ACPI>>Add>>SSDT-PM.aml
Reboot
