Apple MacBook Pro Retina Early 2015 (13-inch Pro, 16GB RAM, 256GB SSD, Intel Core i5 2.7GHz) - The bottom 20% of the screen is black. Model Identifier: MacBookPro12,1 System: macOS Sierra 10.12.6 System reinstallation completed. (I referred to an external display and a YouTube video https://www.youtube.com/watch?v=Z9pK75VPJC0, but it was quite difficult!). Before the reinstallation, the computer was running Monterey. It is also possible to update to Sequoia using OpenCore Legacy Patcher (although replacing the screen is easier, updating is possible with an external display). You can use it as a desktop PC by connecting an external monitor. If you repair the screen, you can also use it as a regular laptop. The battery should last for 1-2 hours, but I don't remember the exact time. The laptop comes with a protective case, and the keyboard is also protected, so it's in good condition. Thank you for looking.
