cMP 5,1 2012 ATI 5870 boots Mojave

[adam9c1]

I was working with a cMP 5,1 2012 that temporarily had the MSI Gaming Radeon RX 560 128-bit 4GB GDRR5


I have since removed the card and I thought I was going to boot off of another drive which had High Sierra on. To my surprise the machine booted up to 10.14.0.
I have updated it to 10.14.2

This is using the Apple 5870 card.

2012 5,1 6core
boot from SSD in slot 1
140 firmware

Yes, while Mojave will refuse to install, it will boot if you swap cards after installation (or boot from another disk already containing Mojave). But your interface and graphics functions will be very sluggish due to lack of GPU acceleration.
