Everybody who thinks that it’s complicated to remove the glass we would like to show the following video. Actually, it is a very simple procedure: you can remove the glass very easily because it is only hold by magnets. This video explains how. Although an iMac is shown, the procedure for the Thunderbolt Display is the same.
The removal of the Thunderbolt Display’s glass is very simple. Instead of the shown big suction cup, you can also use a smaller one. It is only important to lift the glass far enough from the case that you can grab it an remove it from the Thunderbolt Display.
After removal, you can attach GlassFree for Thunderbolt Display. Make sure you hold it on the left and right side and center the the holes for webcam etc. over the right place. Then attach the frame to the Display.
The metal discs will be attracted by the Thunderbolt Display’s magnets and the frame is attached. Should the frame not be centered perfectly, you can now move it a bit to make the looks perfect.
Done!
