Thermal Throttling at 60-70c?

In my own experiments on these Apple laptops, they do not thermal throttle until the CPU temps hit 100C and the fans are running at max speed. Then the CPU will become throttled to 800MHz which is idle speed. You can run the following command in the Terminal app in order to see the CPU speed (aka frequency):

sudo  powermetrics  |  grep  -i  'system average'

This command will prompt you for your admin password. Nothing will appear on the screen as you type the password. Press the "Return" key to submit the password. The command will also keep looping & providing new updates until you quit the utility by pressing Control + C.

You should also try running the diagnostics at the hottest part of the day and when your laptop is hottest to see if it may show any issues.

Another possibility is a power related issue which can also produce very slow performance. Make sure the charger is connected directly to the laptop since some multi-port adapter, docks, hubs can prevent the full power of the charger from reaching the laptop. Also try connecting the charger to another USB-C port especially on the other side of the laptop. Perhaps even disconnect all external devices to see if that makes any difference.

I've been seeing those "ProxiedDevice-Bridge" logs listed in other users' EtreCheck reports when using macOS 12.x Monterey, but I don't know exactly what these are and what they may mean. Hard to say if this is the problem or another symptom.

Are you running any third party apps that are Cleaners/Optimizers/VPN/Anti-Virus

advised to Uninstall all are known to cause issues on the macOS

if in doubt you can  get a good look at your System config. and reveal conflicts or issues, you can download/run this trusted utility https://etrecheck.com  Allow the Full Disk Access for best results.

If you need help interpreting the report you can post it here in its entirety in the "Additional Text" box in the editing toolbar below, in your reply.

you can try SafeBoot How to use safe mode on your Mac - Apple Support will sort many anomalies

Takes a bit longer to get to the login screen, does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, font cache, etc, third party system modifications and system accelerations are disabled,

Reboot  as normal and test.  Caches get rebuilt automatically.

if no insight or resolve—you can restrict TurboBoost to keep the heat down:

Turbo Boost Switcher is an app that toggles Turbo Boost on your Mac

I have an application called WARP that has a VPN option, however its main goal is to remove spikes in ping (in other words to stabilise your internet). It works very well however I could try uninstalling it?

Ill try Turbo Boost Switcher, though just wondering what does it do? Turn your fans up to the maximum?

try uninstalling it—yes this was the recommendation above

CPU: 6-core

Turbo Boost is a feature available on high end intel processors. When a mac is running tasks that are high on processor demand it can boost frequencies to greater levels which results in better performance. However this can cause the CPU to thermally throttle because of accumulated heat, and quick battery drainage.

To counteract these disadvantages Turbo Boost can manage between different levels of frequencies and core counts depending on the tasks at hand.  The third party app can cut out the Turbo boost acceleration.

ProxiedDevice-Bridge multiple crashes...

 run the user Diagnostic...not as definitive as Apple's own AST2 (Apple Service Toolkit) back bench diagnostic, but may kick out an error code.

Have you considered Dust and Pollen in the fans and cooling path?

we had a bunch of work Macbook Pros about 3-4 years old where the fans started screaming as if it was a jet about to take off. Especially when using Zoom.

Turns out they were filled with dust, pollen, smoke particles, etc… in the fans and cooling paths.

Cleaning the fans and cooling paths, returned the Macs to normal operating temperatures.

I do not know if you have dust accumulation. But if you have thermal throttling and no other explanation, and the fans start running fast, then it is a possibility.

if the fans are not running fast, it could be a broken fan.

cans of compressed air have been used to blowout dust and sometimes works.

you can take the Mac to an Apple Store and ask then to check it for dust if you at all suspect it is a cooling problem. I do not know if they would change for that or not.

My mac has recently began throttling seconds after running video editing software or launching games. Im well aware these are intense processes, however I've not had issues with this a month or two ago.

One theory I had is due to the intensive outside heat (constant 40-43c outside right now) my macbook is unable to sufficiently cool itself, however the issue still wasn't solved after pointing a fan directly at the macbook and ensuring all outlets are clear of obstruction

Even then, when i check the macbooks temperature it never even reaches 70/80c and just throttles itself. I understand this is due to intensive load, however like i previously mentioned this has not been an issue 1-2 months ago.

Any ideas or solutions?

What exact Mac is this?

Alright Im not sure what to make of this.

Ive done all of the above and my laptop (for now) is completely fine.
