> the only solution Putting thermal pads on your VRMs and dissipating heat to the backplate works perfectly.

It would work. However since the product is a laptop with the key word being lap... manufactures actually have to throttle beyond what would be required from a physical standpoint. While laptops can and do emit heat from the top & bottom of the chassis that is actually a negative since you have to prevent the user from causing discomfort/getting burned. Although this is a somewhat recent development/concern, you coul…

This is why Apple cannot add the thermal pads themselves, there are some regulations around the temperature limits. I never use it on my lap though. And as mentioned in the other comment "erythema ab igne" is a real thing is seems.

>and the 5500M bug is fixed in Monterey Hm, I still seem to get the same behavior (using the very latest Monterey beta) I'm using the 2019 MBP 16 w/ the 5500M GPU

Damn, I heard it was fixed, then another beta unfixed it - maybe they found some issue with the fix. Fingers crossed on this one I guess.

I also recently discovered that something like 12% of CPU on my 2020 macbook air is used whenever I'm in a room with anything greater than perfect silence, by 'coreaudiod', because it apparently is constantly listening to the microphone built in near the keyboard and spending cpu cycles trying to filter out background noise. Apparently running the signal desktop app in the background is enough to keep coreaudiod cons…

Hi, I work at Signal on calling. Opening the mic while not in a call would be a serious bug, so I looked into it. I ran Micro Snitch and verified that it only sees the mic as active when you are in a call with someone (if you're in a group call and alone, keeps the mic off; if you're calling someone and they haven't answered yet, it keeps the mic off).

So I don't think it's an issue with calling.

However, if I hit the "record audio message" button and then hit cancel, I can get it to stay open until I close the app and restart it. I will report this bug to my coworkers at Signal that work in that area of the code.

Could you try and see if this problem is caused by the voice recording feature? For example, if you quit Signal and start back up, does the bug go away? If you start a voice recording and cancel it, does it come back?

Update: you can track the progress of the bug at https://signalmessenger.atlassian.net/browse/DESKTOP-2406

And if you have new information, please put it there.

The m1 is very early still for compatibility, also doesn’t have 32 to 64 GB Ram. That might work for you but not everyone is the same. Looking forward to seeing the new 16” MBP with Apple silicon, but I suspect ubiquitous software compatibility will be 3 or 4 years away similar to when Apple switched from PowerPC to intel

Yes, everything I use is already M1 compatible. And unless you need to run multiple VMs the 8GB of RAM doesn't seem to be an issue for anyone. What do you use that isn't compatible?

Multiple VMs concurrently.

Docker packages don’t all fully work on macOS itself.

It seems early.

You can add more external displays with a displaylink hub: https://www.reviewgeek.com/75284/everything-you-need-to-run-...

Displaylink is not a real monitor. It is a workaround. It is using a video stream to get the output. So video or gaming is not goting to work well.

Anecdotal reports online seem to indicate displaylink on m1 is fine for everything except gaming including 4k60 video. M1 is not something you really want to do gaming on anyway, especially not with multiple monitors. I’ve done a video conference on my m1 air through a displaylink-connected monitor and I couldn’t tell the difference from having it on the built in screen. I guess it depends what people want to do, but I think for most people most of the time this is a perfectly suitable solution on m1 (not so much on older weaker intel cpu’s though).

I tried this and it doesn't work. Turns out my MacBook was throttling to 30% due to overheating. This happens more frequently if you drive the GPU with an external monitor. Unfortunately the OS does nothing to notify you of overheating and throttling, which is an insanely stupid oversight by apple. I only found out because I noticed that the computer ran fine while running the AC, so I installed an app through Brew c…
