Hervé 2,039 Posted December 16, 2020 Posted December 16, 2020 It could be looking for a Bluetooth device. What happens if you press [ESC] a few times or just wait a little? Share this post Link to post Share on other sites
BakaPhoenix 0 Posted December 16, 2020 Posted December 16, 2020 Nope nothing change pressin esc or waiting for a bit, but i noticed that if i plug off the keyboard and replug it it just wont turn on so the problem might be the usb not only the mouse Share this post Link to post Share on other sites
sunnyboy958 0 Posted December 17, 2020 Posted December 17, 2020 I notice that you use a macpro 6.1 SMBIOS, but it is not fit for your mainboard. Maybe you can try another SMBIOS like macpro 5.1 ,with boot arg '-no_compat_check' and patched dsdt. DSDT-GA-H55M-USB3-F11.aml Share this post Link to post Share on other sites
BakaPhoenix 0 Posted December 18, 2020 Posted December 18, 2020 After changing smbios and using that dsdt (made it into a ssdt-ec using ssdttime) still don't works, i tried removing my bluetooth dongle and the installation goes to the main menu but still no mouse and keyboard working so i can't continue the installation Share this post Link to post Share on other sites
