don't update to 10.15.5 with EFI 5700

6/3/2020

Our friends in Cupertino have broken support for EFI 5700 in 10.15.5.

Stay on 10.15.4 until we get a fix. If your 5700 has a ROM switch and you are on 10.15.5, you can use the PC side to work around for now.

Will update as we find solution.

Thats not really a 'fix'. More of a work around. Yeah, it gets the OS to boot, but none of the hardware acceleration features work. I used a backup to go back to 10.15.4 and its back to normal. Also, much easier doing this from a spare disc, you can just delete and drop the file right in, then run the commands the change the permissions.

Another weird issue with a MacVidCards flashed card is that I cannot get the Mac to boot headless. Once I swap the card out for the exact same model without the MacVidCards bios the PC boots without a monitor attached as expected. Once I reinstall the card and try to boot the PC, it hangs at the point I believe it sends its first signals to wake up the monitor and since there is no monitor to send its signal the boot process just hangs, the system doesn't turn off or get angry just sits there and if you press the power button it turns off very quickly unlike if you press the power button while in the OS. This is problem is unexpected and means that I have to plug in a monitor and stuff it under my desk to get it to boot. I use Thunderbolt displays and they are not detected at boot.

These strange but annoying issues have caused me to not use this card for now and go back to my original partially supported card with no boot screen or pre-catalina support.

On 5/29 I ordered an NVIDIA GTX 980 listed as in stock. I was already charged. It has now been 11 days and I have not received any confirmation that my order has been processed or shipped. I emailed questions@macvidcards.com but received no reply. Order number 2078505112.

My cards were delivered May 22nd and I have sent emails requesting status. Like others have commented it should not be difficult to respond with a quick email letting customers know what the status is. Currently I have three Mac Pros sitting idle while waiting for the cards back. I appreciate what your doing with flashing the cards, but you might want to try responding to customer emails.

Hi Macvidcards team,
I ordered a card from you on the 17th of June and was wondering if you could provide me with an update on shipping? On your website I read that it takes approx 5 days before it is shipped. I have not received any notification yet on its progress.
Kind regards,
Andrew Puffett

Hello Macvidcards team.

Tried emailing quite a few times but no reply so resorting to blog.

Please contact me re my GT 630 I bought from you. Not working correctly.

Thanks so much.

Two weeks so far waiting on a Vega card...
Would be great if you could send it.
Thanks.
