dextergo Posted November 4, 2014 Share Posted November 4, 2014 My powerbook mac unibody screen is broken and is completely dead. So for sometime, I have been using an Asus external monitor with the mac screen closed. Everything is working fine until I tried to upgrade to Yosemite. During the installation the mac rebooted and now it does not display anything on the Asus monitor. I am stuck with the installation process because it is probably asking me where to install the upgrade or some other question. I cannot respond because my laptop screen is dead and I cannot see anything on the external monitor. So the installation process is now stuck. Please help me with your suggestion.

Edward Au Yong Posted August 4, 2015 Share Posted August 4, 2015 Hi, please use another hdd and install the old system. Use a usb adaptor to repair your it.
