Extremely Important: Please match your Macbook year and part number. You cannot deviate from your current screen specifications. Purchasing a screen with different specifications will not work with your system. The newer LCD screens have a high degree of difficulty to replace. Most end users hire a professional to change the screen out.
This is a full assembly. Assemblies are much easier to replace than the screen panel and will give your laptop a brand new look. This screen fitting takes some level of skill - please don't attempt to do it if you're not a trained repair technician.
