Hi, thanks for the awesome work.

I have been using macOS-Simple-KVM for quite a while.

Everything (maybe not everything) works pretty well, except for one function offered in Xcode – Debug View Hierarchy.
The button to trigger that function looks like this:

In my current kvm, after I trigger this function, it shows me nothing but a blank background.

After some digging, I found it may be related to the lacking of OpenGL.

I am planning to migrate to Docker-OSX. But before that, I'd like to know if Debug View Hierarchy works within Docker-OSX.

Thanks.

You can test it out pretty quickyly, make a copy of you .img and insert it into the container as per the readme.

All the repo's use the same files :)

If you haven't used Docker before, just follow the steps at the top of the readme.

When it boots, docker ps, get the id of the container.

docker inspect id | grep Upper

and overwrite the .img file in that directory with your existing .img

Then docker start id

Use a copy tho because I don't wanna hurt your existing .img

Thanks for the suggestion.
Frankly, that doesn't sound very easy to me.
I plan to take the action when Big Sur gets released (likely before November).
So, if Debug View Hierarchy doesn't work, at least I will have the new macOS. 🤪

Confirmed.
It doesn't work.
Just a blank background.
It seems OpenGL is mandatory.
Closing.
