MacBook Air 2015 CPU speed drops to 0.6 GHz during rendering web pages and videos
So, I have a MacBook Air from early 2015 and it runs Catalina 10.15.7. There are no thermal issues, over 70+ GB free of 120 GB on the disk, Monterey makes it run even slower so I have Catalina 10.15.17. The CPU would throttle to 0.6 GHz when loading anything “significant” (like a 1080p YouTube video or a business insider page). The laptop had been used for playing video games so it might’ve been running hot but it does not exceed 50 degrees now, but the CPU speed would still drop to 0.6 GHz loading stuff. I’m sorry if the story is confusing but can anyone help me as I’ve tried an SMC Reset, NVRAM/PRAM reset and even ran diagnostics and it said nothing was wrong but something is clearly up and I can’t figure it out.
