Hi guys,

Another interesting M1 misbehaviour example...

I have noticed yesterday that my kernel_task process wrote over 9 terabytes of data within a week... I have a feeling that's a bit much?! Computer spent most of the time sleeping and when on, it was only used for browsing.

Yes - I do use on average 10+ tabs if anyone wonders... It's an MBA M1 8GB machine. Also computer has been on only for a week.

I did a reboot yesterday evening and since kernel_task already wrote over 100gb's of data.

Is this normal?

Meh.

Thanks!

That is not normal. Here’s the stats from my 2018 15”. Uptime is 8 days, 12 hours. I also use quite a few tabs. FWIW, my machine has 16GB RAM.

I am sitting at 370gb within one day atm.

Will try to contact apple and see what they say. I have already done NVRAM reset and run diagnostics - nothing suspicious came up.

Thanks guys!

Try to remove all the third-party apps that modify the system, for example Avast.
Removed Avast and rebooted - managed to get 16gb in two hours. No other system modifying apps are present at the moment.

Why is Kernel_task writing to the disk? Is it memory swap? I just looked and I don't have any Kernel_task writes at all. Y'all mining BitCoin? :)

Never mind, I wasn't looking at system tasks.

8GB in 5 days of uptime.
