Sadly no.does the Pulse RX 580 retain its proper VBIOS and as such the custom framebuffer personality it gets in OS X?

Sadly no.
- They will offer a flashing service for existing cards
- Boots properly and shows bootscreens connected to 4K monitor via DP1.2
Yes, a new EPROM needs to be soldered onto the board in place of the existing part. Hence the expense and the lack of a do-it-yourself option.Does the card need to be physically modified in any way ?
I have ordered one, I am just curious
but everytime when i slept the computer the monitor did not get a signal on waking (but this has happened once before with the stock card) so i switched from displayport to hdmi and the sleep/wake thingy is all good again...
That is because HDMI 2.0 only supports 4k 60Hz 8-bit. DP 1.2 supports 4k 60hz 10bit.At the risk of being a bit off-topic, I want to give my input on this issue here. I have an LG 4K display (27UD88-W) and unflashed RX 580 (Sapphire Pulse). Since 10.14.4, display wake has been a major problem. I've mentioned before that the culprit seems to be DP. And while using HDMI is certainly possible, I've noticed that the image quality of HDMI is a bit inferior, particularly involving red colors:

What I have found to be most interesting is that if a pass the DP signal through my Titan Ridge Thunderbolt card (it has an DP input and output), then the wake issue is gone! This is what I've resorted to.

Macstore UK (MVC's partner over here) told me it was a physical change. But then, they are yet to offer a flashing service on customer cards. ' I would expect that in the coming weeks we may be able to offer a flashing service for the Pulse card but highly doubtful for other models for the foreseeable future.' Which is, frankly, a load of horse manure. If the guy who wrote the ROM can do other models, so can they. I pointed out all the models MVC is offering have the same port config as the Pulse, and even offered to pay them to do my Aorus as a guinea pig card. They have yet to reply. Not good. I might drop the Polish guys a line, see if they're any more willing to actually take people's money…The MVC EFI ROM has the same 262’144 Byte as the original Sapphire Pulse ROM. No need to solder another EPROM chip.

^^^^I have run MVC flashed cards for a few years now, and know of no negatives. After boot, upon reaching the desktop, the flashed card will behave like any non-flashed card. The MVC card will behave on boot, like what used to be called "Mac Edition" GPUs supplied by Apple in the "old days" and by EVGA more recently. But, as of right now, no third party supplier of AMD cards makes a Mac Edition card, and of course Nvidia cards are no longer supported by Apple. The MVC cards provide a boot screen that allows the user to do the processes the boot screen allows.

Further reply from Macstore UK: "At this point in time we have only had conformation [sic] that the EPROM chip we stock from MVC will work stable with the Pulse card. MVC may now be offering flashing or other 580 options but as we have to buy a large number of EPROM chips upfront for the Pulse card it doesn’t make commercial sense to buy further large shipments of EPROM chips for primarily mail in service. If the situation changes and we can offer more 580 selections we will be able to offer you the service on the Aorus card.
It was decided to do physical EPROM changes instead of flashing to solve the issue of other vendors making copies of the MVC ROM."
Which is fair enough. Waiting seems like the best option, sadly…
Given second hand prices have tanked on account of all the mining cards being dumped, and the price of a flashed card…I'll pass.Sell your card on eBay and buy the Sapphire RX 580 from macstoreuk.com. Better than waiting for a flashing service.
Even with a flashed card the 5,1 is still blacklisted from being able to use FileVault in Mojave.
You may also find this funny. On the 3,1 you can enable FileVault on Mojave with no fuss.
