When Unity editor is in the foreground, without pressing Play, only in editor mode, the CPU goes up to 30% usage.
With what even increases more when you press Play in the editor for the game’s own consumption.
The problem can be easily reproduced, creating an empty project, and viewing the process list while unity editor is in the foreground.
How can I fix this?
Thanks
Does this happen in a new project or just a specific one?
Try using the profiler in editor mode to see what could be using up the CPU.
It happens too with Unity 2018.4.7f1, using Editor Metal API does not resolve the issue.
I found this thread on the Unity subreddit, I’m not sure how long this is happening, it seems from Unity 2018.2.f2:

I attach a screenshot of the profiler in one of the CPU spikes in a new empty project:
@[karl_jones]( 2018.4.8f1 editor high CPU usage macOS members/karl_jones.834128/) any news about the bug? Thanks.
I have already sent a bug report.
Not that I’m aware of. Do you have a bug number so I can check?
I just reported it. Case number: 1183039
Thanks.
Just to confirm seeing this also. When in foreground, unity usage jumps up to about 80% on my machine, while doing nothing in the editor.
@karl_jones In my case I’m seeing heavy memory allocations every frame, with a large CPU tick on garbage collection.
Is this in an empty project? Looks like you may have an editor script causing that.
Yes we’ve tracked it to google’s PlayServicesResolver. So apologies unrelated to the issue herein, but still of note to others running google plugin (it’s doing this even if in iOS mode)
