这个帖子我也参照过修改了,https://www.tonymacx86.com/threads/guide-laptop-backlight-control-using-applebacklightinjector-kext.218222/,里面没有IntelBacklight.kext (and/or ACPIBacklight.kext)。但是好像要修改这里:Note: If you already have patched your DSDT (or SSDT) with a "Brightness" patch (PNLF), you must remove it! Same if you're using Clover's AddPNLF_1000000. Also Note: The SSDT-PNLF.aml assumes that GFX0 (or VID on Thinkpads) is already renamed to IGPU. It will not work if your IGPU is not at _SB.PCI0.IGPU.
