Early 2015 Macbook Pro is making a crackling sound on the right side of the laptop

Thanks for your reply. I reset my NVRAM/PRAM and the SMC.

What I meant when I said "it appears to have gone away. However, it has only been a day or two." the sound no longer occurs, but it is still too early to tell I believe.

I also did the audio system check and everything seemed fine. I also changed the sound effect in system preferences.

End of report

Why are Time Machine backups important/how will they help? As for uTorrent, some websites provide a torrent (like Unity3D) which is more convenient for me to use. I don't think the uTorrent app itself would harm my computer in anyway, right? As for Red Crucible, if I continue to play this game will it eventually ruin my Mac? Like in the long run?

Thanks again! 🙂

Thank you! I'll hold off on the heavy programs/games then. Thanks again! 🙂
