When I am doing a month long render on my PC putting 100% load on all 6 CPU cores, both GPU's, ALL of my RAM, and constant random reads and writes to my SSD, am I wearing anything out? 😕
Kidding! 🙄
Nope, you're fine, the computer is being worn out by just existing, you are definitely not harming it by listening to iTunes playlists for extensive amounts of time 😉
