The M1 Pro MBP has been experiencing frequent intermittent stuck recently.

Specifically, the computer suddenly gets stuck for a second, the screen brightness flashes, the CPU load of the activity monitor has a spike, and then returns to normal, once every once in a while.

Anonymous20 May 28, 2025Find a tool that can detect the main frequency of the CPU to see if there is a sudden frequency reduction. Sometimes it is not that the load has increased, but that the CPU has shrunk

Anonymous22 May 28, 2025I also encountered it with my M1 Pro mbp14, but suddenly it didn't show up again recently? Usually, when I watch HDR movies with IINA, the CPU is fully loaded in the background for no reason, and then it gets stuck, sometimes for three or four seconds. Unlike the frequency reduction, the power consumption of the whole machine is less than 10w and the load is very low. It is inexplicably full and you can't see what process is using the CPU.

Anonymous20 May 28, 2025@ Anonymous22 Isn't this a typical down-frequency? I encountered it when using Intel. Suddenly the CPU dropped to 1.0 GHz. The original load directly filled up the performance of the 1.0 GHz, and the jam exploded.

Anonymous23 May 28, 2025I have never encountered such a serious one. I turn on the phone for more than 8 hours every day. However, it is true that when I cut the Chinese and English input method with its built-in, the efficiency will fly a little...

Anonymous22 May 28, 2025@ Anonymous20 I have a power meter plugged into the socket all the time. Normally, the power consumption of the Mac is only 10w, but when the load is suddenly full, the power consumption is directly pulled to 35w. How can the power consumption of the whole machine increase while the frequency is reduced? And it has only been reproduced when iina plays videos, and it has not been tried during idea compilation or other high-load exports.

Anonymous27 May 28, 2025The same has been true of m3 air in the past two days. I told my colleagues a few days ago that there had never been a performance bottleneck, and then suddenly intermittent lag occurred

Anonymous6288 May 28, 2025Listening to this description I feel like something hdr related has gone wrong. The CPU will rise a little during the sdr to hdr conversion, and then there may be some noticeable brightness fluctuations as the system is adjusting the screen brightness
