[HELP] XFX ATI Radeon HD 5770 1 GB no display monitor active on OSX Mavericks and Yosemite

[Adrian B]

1024x 768 resolution and 3mb RAM is typical of GPU cards that do not properly work in OS X. Keep trying different things but I think that sooner or later the best solution is to change the card. The XFX branded HD 5770 were always a handful to get working. Have a look at this Mountain Lion thread:

My 5770 works in Snow Leopard with ATIDriverPatch10.6.8.pkg: http://www.tonymacx86.com/snow-leop...eopard-10-6-8-xfx-5770-card-issues-fixed.html

For Yosemite, I try to patch the framebuffer.

Decode the BIOS of the graphics card has to spend carefree:

$ redsock_bios_decoder < backup.rom
