@mweststrate Thanks for the help !
Looks like I have a problem with idb.
I'm actually trying to reinstall idb and idb-companion on my machine, but not really working for the moment.
I've the following error with idb list-targets:

That looks a lot like facebook/idb#671

[magrinj]

@mweststrate Thanks, yes it's the same error !
Sounds maybe related to last Mac OS update 🤔

[L-Yeiser]

@magrinj when your mac starts to overheat are you seeing a massive spike in the kernal_task usage of CPU. My computer has been slowing down over the last few months and after I upgraded my OS I cannot run flipper and xCode without massive issue.

[magrinj]

@L-Yeiser No I don't see any kernel_task at the time, and no massive spike when running flipper and a simulator.

But I saw this post on stack exchange that should help you: https://apple.stackexchange.com/questions/363337/how-to-find-cause-of-high-kernel-task-cpu-usage

Apparently high kernel_task is due to high chassis temperature...
And plugging the power adapter on the right side can reduce this apparently 🤯

[nikoant]

Looks like now we're discussing another issue :)

[magrinj]

@mweststrate You got it right, after upgrading idb to latest release that fix issue with latest Mac OS, idb is now working properly and Flipper stop overheating my Mac ! Thanks for the help and pointing the direction where to look !
