Although mine boots up at normal speed, there is a way to solve the slow boot time. We add the following in OpenCore as an ACPI patch (credit: @Elias64Fr) with Signature = DSDT:
Comment: disable \_GPE.TINI (Zero, RPS0, RPT0, Zero)
Find: FF5C2E5F 47504554 494E4900 52505330 52505430 00
Replace : FFA3A3A3 A3A3A3A3 A3A3A3A3 A3A3A3A3 A3A3A3A3 A3
Thanks. Can you be so kind to please point me to the relevant .AML file to do this?
And the slow boot time that I'm talking about is from when I push the power button to when the system finally gets to the opencore bootloader screen. Takes about 20 seconds... took only 5 prior to flashing. Will this DSDT that you reference fix the POST speed (i.e., before opencore loads)??
Thanks so much for helping us out!
Edit: I just read you said Opencore patch. Okay I'm going to try to implement this using my plist editor, but if you could be so kind so as to post the relevant plist code to implement this that'd be sweet. I've never implemented an ACPI patch before. I'm going to do some google-fu.
Edit again: I think I figured it out, it definitely spend less time at 'Read 62 Blocks of AML code' so something is working. Prior to the ACPI patch, the system would freeze on the 'Read 62 Blocks of AML code' line for approx 2-3 seconds. But the time to get from 'power button press to opencore screen' is still 20 seconds or so...
