Tips
- Some models of MacBook Pro, especially ones released in 2016-2018, have a design flaw where the internal ribbon cables connected to the screen wear down and break easily with regular use. If you have an older MacBook and you notice problems such as a stage light effect on your screen or your display going black or flickering when you open it past a certain angle, you might need to replace your display or get a new laptop.Thanks
