Couldn't alloc class "AppleKeyStoreTest"

之前用好好的,稳定运行半年多。会突然黑屏,重启。格盘装Windows也会黑屏,于是升级bios,还是不行。才发现是AMD掉驱动。想重新装回macos发现已经不行了,一直报错
Couldn't alloc class "AppleKeyStoreTest" 🤣

核显模式下分辨率仅2k

如题:我用您的efi安装了Sonoma,因为我的核显使用,因此定制了hdmi输出 ,但最终仅能运行在1440*1080分辨率下,显示比例很奇怪。并且无法在系统内设置,最高就是这个分辨率。我用的是4k显示器,之前 有显卡的时候使用正常。
请问有什么方法解决吗?还请不吝赐教。

关于4K显示器最高只能用2K或以下分辨率的问题,config配置有问题

参考帖子:https://bbs.pcbeta.com/forum.php?mod=viewthread&tid=1849099
核显配置里framebuffer-stolenmem给了00003001,删掉就可以4K分辨率了

framebuffer-stolenmem(给 BIOS 中 DVMT 添加一点内存大小,会影响高分屏,这个值必须大于 32M,也不应该过高):

  • 一般 1080P 屏幕的话,设置为 48M 就够用了:00003001
  • 当你的笔记本电脑屏幕是 2k,你可以设置为 64M:00000004
  • 4K 屏的话,要设置为 128M:00000008
    如果你的 BIOS 中可以设置 DVMT 的话并且你设置成为 128M 之后,可以不需要设置这个属性,或者这个属性设置小一点:00003001 保险起见,高分屏直接设置成 128M 比较稳,并且保证在 BIOS 能设置 DVMT 的情况下设置在 64M 或以下 (PS:这一部分可能有误,但是最后一句保险起见,高分屏直接设置成 128M 比较稳是试验过的)
