That's some madness. I spent two days with a cold Mac but today it is boiling. The same CPU load and DAC connection, 70 Celsius. Just report. :)

Mac has an alum case and I feel the heat by my hands. Also I sensitive to fans RPM.

I found it. USB TypeA to TypeC OTG adapter makes MacBook hot. Direct TypeC to TypeC cable doesn't produce signigicant heat.

Just received SMSL SU-1, XMOS instead of Unison USB chip. The same story - 0% CPU load but +15 Celsius on cores. Also I did some tests with other USB devices like external SSD, flash etc and can confirm than ANY USB activity makes cores hotter. I don’t know how you guys avoid it. The most...

Got my Intel MBP a little bit hot with the Modi (and cold without it). Any USB incompatibility?

Like 3+ more than ESS.

However, there are a lot of claims about MacBook USB in internet. Charging, using dock stations, left vs right ports etc.

I spend all day without any USB devices. No heating, no fans. The same working tasks. Why not, let it be internal DAC.

It seems I should try another DAC.

Chrome + Spotify + iTerm...

Is yours Intel model?

MBP 2019 16", Core i9, 32RAM, it's damn powerful laptop. A month or so I used its internal DAC from 1/8 socket and everything was fine. Then I decided to make a real Hi-Fi station and connected Schiit Modi 3+ (2 watt comsumption), and got a heater. Reconnected from the left USB to the right one...

Yep, I tried hibernate mode and got zero battery in the morning.

Any MacBook users here? How to sleep USB when the lid is closed?

Found the solution: https://www.head-fi.org/threads/akg-k701-q701-k702-k712-headband-elastic-quick-fix.796604/

Not broken, too loose.

Any ideas to fix old adjusting rubbers?

Even audiophile icon Volumio allows to use software volume control. But Mac not. :)

But why? Windows or Android can adjust volume.

No volume control on MacBook. Is it ok?

Yep, don't listen, just read reviews.

But A2 is more hot :)

Well, to come back to the sound I've made some quick tests with Win11, Mint Linux and RPi3 Volumio, the same DAC of course. It seems like no difference. Maybe it was some mood effect.

Any OS is just the way to click icons on desktop. However, we talk about sound here .
