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.
