Kay, the ~ in my example should be filled with your username, found in the Users folder. If you did that and still can't find the folder, you might have a fresh or a faulty install.
same here M1 Max 16 inch 32gb , i just got edge high power consumption issue mid jan 26 and found this thread. I'm now following WCR comment.

Updating to version 144.0.3719.92 fixes this for me. Updated when going to Settings > About Microsoft Edge.

I experienced the issue with version 144.0.3719.92 and the previous version as well.

I'm on Tahoe 26.2 with Version 144.0.3719.92 (Official build) (arm64).
~/Application Support/Microsoft does not have an /EdgeUpdater directory.
~/Application Support has
I have hidden files enabled.
Curious if that means the later versions of Tahoe/Edge don't have the EdgeUpdater?

Open Activity Monitor, search for EdgeUpdater, then invoke an update check in Edge. You may find its path there. (I'm using macOS 15.7.3.)
Jon, that did it.
Here is the full path:
'/Library/Application Support/Microsoft/EdgeUpdater/145.0.3785.0/EdgeUpdater.app/Contents/MacOS/EdgeUpdater'
The trick is WCR (who is right in his answer) had the pathway from the username.
'/Users/~/Library/Application Support/Microsoft'
You have to go from the root if you're using WCR's suggestion (again, no shade):
'/Library/Application Support/Microsoft/EdgeUpdater'
It seems this is one of the changes in macOS 26. I previously wrote a detailed step-by-step guide on the second page of this issue.

I have the same issue of 100% CPU utilization on my M1 Macbook Air, leaving this comment in hopes that Microsoft patches this as soon as possible. Having my mac overheat and quickly drain battery just because of a browser software issue is a massive problem.

same here for Macbook Pro M4 Pro 48GB 512, never experienced this before, only after updating to the new version a couple days ago.
Is this bug still present on version 144.0.3719.104?
Same issue in 144.0.3719.104, the screenshot is below.
Same here.
This is the main process, not an extension. This should never go to 100%.
It happens every time after a few days. Restarting fixes that for that day or maybe next too.

Following WCR comment, the usage went from over 100% to under 10%.. huge difference. I was also on build Build 144.0.3719.82 and rolled back to 143.0.3650.139
