High CPU usage on macOS
It might be worth noting the website you were trying to access at the time, as this can also have an impact on CPU / RAM consumption.
For example, we currently have a very similar experience in Safari 13, when accessing SharePoint Online pages using a particular web part. The issue (we believe) is partly due to changes in Safari 13, which have caused incompatibility with elements of this web part. In short, the two elements --- browser and website --- have to be considered.
One further note: I have been experiencing massive CPU spikes in other applications in MacOS Catalina recently e.g. Affinity Photo & Affinity Publisher. These previously ran seamlessly, so I am starting to wonder whether OS update 10.15.3 is itself the issue. We should really call it MacOS Vista! 🙂
It might be a compatible issue with Catalina. Personally, I really like some security improvements with Catalina, think they are heading to the right direction. Such as its "read-only file system", it might be a decent solution to the system security and upgrade stability in a long run. But such many problems are indeed frustrating. So yes, I can agree on the term MacOS Vista 🙂
yuguo Yeah, when the CPU starts to spike, closing all tabs does not fix the issue and I also am forced to "Force Quit" it.
It's possible that some specific pages are causing some internal parts of edge to crash continuously. That would explain why closing all tabs does not stop the crash, once the crash loop starts it doesn't stop. (I'm just speculating at this point).
