I have a five-year old 2017 MacBook Pro with 8 GB of RAM. After hours of use, and never on startup, my MBP continuously beeps, and it does not stop for several minutes.
While it is beeping, I can’t use my keyboard (I have an external mechanical keyboard, a Keychron K4, in case it is the keyboard malfunctioning – some of the keys are giving in, I think it’s the switches). Worse yet, it starts erasing words and lines and paragraphs very rapidly in important Word documents I am working on!!
I have to save immediately, close, and then restart otherwise it will delete the entire document.
When I restart, I have to fix what I lost.
What could be causing this malfunction and how do I fix it?
