Ninno Posted February 16, 2019 Author Share Posted February 16, 2019 Thanks a lot, now the shutdown is perfect, 1-2 seconds. But the startup is now slow due to an error on the GFX firmware, how can I solve it? P.S. How can I see which kext are installed in the l / and or s / l / e directories and possibly remove them? I'm not sure I've ever copied them to these folders. Thanks again Photos.zip Link to comment Share on other sites More sharing options...
Ninno Posted February 16, 2019 Author Share Posted February 16, 2019 I added -disablegfxfirmware in /Boot/Arguments And now the startup is ok too Link to comment Share on other sites More sharing options...
