系统版本: 10.14.5
CPU:E5-2689
TDP:115W
Base Frequency:2.6GHz
Turbo:3.6Ghz
8 Cores &16 Threads
GPU:AMD Radeon HD7850
VRAM:1GB

在启动时Inject ATI可以正确识别显卡型号,如果不注入则会识别为R9 270;但是两种情况下均可正常驱动显示。但是两种情况下都无法开启H.264硬解码,观看4K分辨率视频会有很高的CPU
占用并且有些许卡顿。了解到如果CPU不具备核心显卡(除特定显卡外)无法完成硬件解码H.264视频。请问这种问题有没有解决的办法?十分感谢!

是否尝试过iMacPro1,1的SMBIOS?
另外,使用VideoProc硬件检测的结果如何?

尝试了iMacPro1,1和Mac Pro6,1都是不可行的。另外VideoProc检测的H.264和HEVC两者都是不能硬解的。谢谢!
