Just a tease with no details but for what it's worth:
My guess is the 7,1 is not going to use the same boot screen standard as the 5,1. All the other Apple products have probably moved on.No doubt there should be some development on this front once 7.1's start shipping. Apple has to have preboot config screens on those new machines and no doubt someone will dump the rom for us to flash for the older towers. Glad MVC has something brewing. I commend his skills for those of us clinging onto our 5.1's.
I'd tend to agree with your perspective here. Likely they have changed the behaviour of how the GPUs used to function, but until shipping them and someone has a look, the magic curtain will get pulled back.My guess is the 7,1 is not going to use the same boot screen standard as the 5,1. All the other Apple products have probably moved on.
It’s likely the 7,1 will actually be compatible with standard ROMs, and won’t require flashing at all. But if there are custom ROMs on the 7,1, they won’t be compatible with the 5,1.
MVCs is probably about to see their business start to dry up once the 5,1s start going out of service.
I am sure it is already working and we will see the commercial version on the MVC site. Hopefully there will be mail in flashing service offered as well.
Yes he said he will provide it in his forum.Will they have an option to flash your existing 580, or will we have to buy theirs?
ProvideConsoleGop Type: plist boolean Failsafe: false Description: macOS bootloader requires GOP (Graphics Output Protocol) to be present on console handle. This option will install it if missing. Note: Some drivers, like AptioMemoryFix, may provide equivalent functionality. These drivers are not guaranteed to adhere to the same logic, and if a quirk is necessary, this option is preferred.
I've been contemplating OpenCore for some time, but have held off on any experimenting, because it is not clear if it adversely affects the BootROM of the cMP...If we can make this work it will provide boot option with the bootloader with an included GOP driver if there isn't any already in the Video card ROM.
Totally agree with you. I able to jump between macOS and Windows installations without ever holding down the Option key. I'm also able to format and perform a clean install as well as going in to recovery mode without it.Having had my RX580 running for 21 months, I really havn’t missed the boot screen........
And a couple other tidbits from the comments:UPDATE: To clarify, these cards are 95% done. Will be offering 580s for pre-order as soon as I remember how to add a product to the website. US MVC will be shipping within 2 weeks, barring any roadblocks .I believe our European partners will be onboard as well.
