faby1992 Posted May 1, 2020 Share Posted May 1, 2020 My Lenovo X220 with Catalina 10.15.4 works pretty well but shutdown results in a reboot and instantly wake up from sleep. If I disable Wireless card on bios (DW1510) the problem disappear. If I enable "Wake for network access" in Energy Saver and AC power is plugged in, the sleep works. I think the problem is something about power management but I didn't find a solution :/ EFI and kext are the same of this repository: https://github.com/x-t/x220-catalina-efi Link to comment https://www.insanelymac.com/forum/topic/343650-lenovo-x220-dw1510-prevents-shutdown-and-sleep/ Share on other sites More sharing options...
