Mald0n, you are awesome, thank you very much in advance for your assistance. Here is the updated SendMe.
Do you recommend I use this new plist (with iMacPro1,1 as opposed to iMac19,1) with this configuration? The EFI as currently engineered does not shut down the machine but I can try to tweak it.
Thank you again.
