So let me teach you something you need check when buying a MacBook.
When buying a macbook you check the speaker, battery health , keyboards and probably the charging port. But most people hardly check cameras because they feel it should be working not an issue, it is a big issue o when you wan to get a MacBook after checking the things I listed above make sure you check if the camera is working, go to the settings and check if it disabled if the laptop doesnโt detect any camera at all this is a big issue.
MacBook cameras comes with the screen it canโt be repaired separately like Hp and Dell . So if the camera has issues it simply means the screen was replaced so watch out ๐ซต๐พ.
