lamatta17 Posted February 26, 2018 Share Posted February 26, 2018 Hi every body, i have a Dell M6700 with AMD FirePro (ATI HD7870) and CPU i7, 3740QM, 2.7GHz. i've tested everythink from this and other sites, to install High Sierra. No luck. Boot from USB-Stick ends with a black screen after the apple. Please give me a working EFI directory to try to install, so that i can optimize the system after installation.
