How can I remove the glass from the macbook display to get to the wifi antenna? I have a 2014 MBP that is water damaged. The display and battery no longer work and I do not have the cash to repair it, so I decided to turn it into a desktop. The keyboard and trackpad work perfectly fine. But I had to remove the display, it will only allow me to work an external display if the lid is closed but will only power on if the lid is open. So far I tried using 4 different external USB WiFi dongles but none of the drivers are compatible with El Capitan. I considered using a USB to Ethernet adapter but I would strongly prefer to use the stock wifi card and the original antenna
It is not possible without destroying the LCD, just replace the whole lid. Or you can buy a spare cable/antenna assembly and just connect the antenna.
