描述
Bootloader: OpenCore v0.5.9 macOS Version: 10.15.5
Start from Release v1.3.8, we add framebuffer-flag property to support certain features on ig-platform-id: 0x591C0005, for example, support hidpi resolution higher than 1440x810.
However, after some tests, I noticed that the FBEnableDynamicCDCLK flag will break wake up from hibernate mode 25. Workarounds are to close the lid and reopen it, or set hibernate mode to 3 or 0.
A better solution is to disable the FBEnableDynamicCDCLK flag by setting framebuffer-flag to CwfDAA==. But after doing this, the device won't support hidpi resolution larger than 1440x810. It's a trade-off, and for now I find no better solution for this. macOS is known unfriendly to the low-resolution screens like the 1080p screen on XiaoMi-Pro.
