What's funny is interacting with it in claude code. Claude-desktop-cowork can't do anything about the VM. It creates this 10 GiB VM, but the disk image starts off with something like 6-7 GiB full already, which means any of the cowork stuff you try to do has to fit into the remaining couple of gigs. It's possible to fill it up, and then claude cowork stops working. Because the disk is full. Claude cowork isn't able to fix this problem. It can't even run basic shell commands in the VM, and Opus4.6 is able to tell the user that, but isn't smart enough/empowered to do anything about it.

So contrary to the github issue, my problem is that it's not enough space. So the fix is to navigate to ~/Library/Application\ Support/Claude/vm_bundles, and then ask Claude Code to upsize the disk to a sparse 60 GiB file, giving cowork much more space to work in while not immediately taking up 60 GiB.

Bigger picture, what this teaches me though, is that my knowledge is still useful in guiding the AI to be able to do things, so I'm not obsolete yet!

So it's using it's binary disk/image as the cache/work disk also?

Yea, that's a receipt for problems.
