I have an Intel Macbook Air from 2012 with Catalina. When I try to boot it on, it plays 3 beeps, then pauses, then beeps again, so on and so forth. All I've read online is that I need to configure it at Apple because the memory is not working.
This has happened before, but the first time, someone I know somehow fixed the laptop through unknown means without going to the Apple store. This time, I do not have the help of said person and I do not know how to fix it by myself.
Can anyone help find a way with this information?
