High CPU usage on macOS
I'm still getting very high CPU (300%) usage at random intervals on macOS. I have kept Windows Defender Smartscreen completely disabled and this issue still occurs. (On Edge Dev v81.0.416.6, macOS 10.15.3)
Are there any plans to fix or any way for me to send some kind of diagnostic info to hopefully help get this issue fixed?
Yes, I have the same problem. Tried stable(80.0.361.56) and beta(80.0.361.53) versions with Smartscreen disabled. It occupies 95~150% cpu after some random time and can not be closed properly.
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! 🙂
- Thank you. However my situation is that the Edge consumes very high cpu even after I closed all tabs. And if this happens, I can't terminate it without "Force Quit". So I guess this does not relate to any particular website.
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 🙂
