DTServiceHub and diagnosticd causes high CPU usage on Mac

[arnnis]

🐛 Bug Report

When I open flipper these two process causes big CPU usage and fan noises. this is what I get in the console app, there are many of this error:

Failed to bootstrap path: path = /Applications/Xcode.app/Contents/SharedFrameworks/DVTInstrumentsFoundation.framework/Resources/DTServiceHub, error = 2: No such file or directory

I went to that directory and DTServiceHub was there.

I had similar issue with instruments process months ago and opened an issue here but can't find it right now.

related issue: #1992

To Reproduce

Just open the flipper app

Environment

OSX: 10.15.7
Flipper: 0.83.0

Please make this high priority because it's very annoying

XCode version: 12.3

To be fair I'm not sure what to do with this report, as it seems to do with your specific installation. Did you try another machine / reinstalling XCode to see if the problems persist? We do use instruments indeed, but I can't really reproduce your symptoms (XCode 12.4, same OS). Note that you can disable iOS support in settings. It might be interesting to check if disabling physical iOS device support makes a difference. As said diagnosticd is not a something we use / spawn. Maybe your installation is interfering with something else. Are you using a special virus scanner, atypical disk setup, or running an old version of idb?

The issue was from my idb installation. I'm not getting the diagnosticd process now.

Flipper GPU helper is using so much cpu on idle too. There are some warning in the Electon console about my adb installation. Will check if those will fix the issue.
