Hi, I succesfully installed "High Sierra" on a Toshiba P755 and it's working fine I guess, the only issues I'm currently having is that I can't select anything with the touchpad, meaning the touchpad does work but I can't click on anything, the touchpad is a synaptics, I use a usb mouse because of that. The other problem I'm having is that wifi speed is super slow and would like to fix it somehow, the wifi card is an atheros ar9485 and I'm using IO80211Family.kext if that helps. Thank you very much.
