On SMBIOS iMacPro1,1 using a Radeon RX 580 8GB breaks Apple H264 / H265 API. Meaning exporting in those formats will hung Final Cut Pro and Da Vinci R15 or any other apps that uses that route to transcode files.
For VEGA video cards such API work fine as it works for Nvidia cards.
Simply put the RX 580/570/560 are not contemplated by the SMBIOS iMacPRo1,1.
Is there a way around the issue?
I'm running an X299 machine with SMBIOS MacPro5,5 and magically Radeon RX 580 8Gb can now decode and encode using H264 /H265 both in Final Cut Pro and Da Vinci R15
Some poeple say SMBIOS MacPro5,5 would have negative implications. So far such SMBIOS seem to work just as fine as iMacPro1,1.
Any idea how to make SMBIOS iMacPro1,1 render H265 / H265 on RX 580?
Thanks
