7MB VRAM and no GPU acceleration

Hey guys,

Been out of the hackintosh world for a long time. Been on OS Maverick since 2013, still use chimera/MultiBeast. I primarily use my Mac for audio production so I have no need to upgrade.

Recently went from a r9 280x to a RX 590 and my mac no longer recognizes the card. From my understanding, you need Radeondeinit enabled but I do not have clover? Is there anyway around this
