Hello,
I am trying to install High Sierra or Mojave on this laptop, but with success only about 50%. No wifi, no ethernet, no sound, GPU shows only 4MB Vram. So i deleted everything and want to star over. So, can you help me starting with opinion if Mojave is possible, or should I focus only on High sierra? Next one, can I use 120GB SSD for installation? is the amount of disk space worth the speed of SSD, or should i leave the 500GB there? Thanks and greeting from Czech.
