Describe the bug

The data.img sparse bundle size (8.8TB reported on my Mac) prevented me from using Migration Assistant, which does not provide helpful errors. Understanding the context with #29, I am opening this ticket anyways. I appreciate the forward-thinking adoption of this image format, but clearly even Apple's backup and recovery tools are not yet ready to adopt this.

It was only after failing multiple times to migrate, even thinking of recursive disk space traps, that I identified data.img as the culprit. During use of Carbon Copy Cloner, which reported that it "Discovered" 9.2TB of files but then successfully saved ~400GB that I was able to use CCC's audit function to identify that it registered data.img as being 8.8TB in size.

Apple's migration tool provides notoriously little feedback, and I am opening (yet another) Radar about this. But OrbStack is claiming the juice is worth the squeeze to move forward with Apple's modern tools... when Apple's tools clearly aren't expecting this yet either.

To Reproduce

1. Use OrbStack as you normally would.
2. Attempt to migrate to a new Mac using Migration Assistant
3. Observe that Migration Assistant will calculate a total space requirement that fits on the new Mac
4. During file migration, the process will stop stating there is "not enough space" every time
5. Delete data.img from the source drive
6. Reattempt migration
7. Migration succeeds.

Expected behavior

I would be able to migrate from my old Mac, to my new (which has larger storage, not less), without finding and deleting data.img.

   We exclude the data image from Time Machine since Apple lets us. It doesn't look like there's a way to do similar for Migration Assistant. Going to keep this open in case we come up with anything, but for now, the ball's in Apple's court.

   Should this at least be better documented/FAQ'd? I'm not expecting an alert in the application, obviously, but this only came to my attention because another tool pointed to the OrbStack file and then I found the legacy issue here on Github. In addition to this, it required non-standard tooling in order to actually backup data.img and restore it. I didn't find any solution to enable Migration Assistant besides deleting the file from the source machine.

   If I had moved forward with just starting the second laptop from scratch and attempted to move the file, I would have been hit by similar messaging/failures in Finder that the file is too big for the destination. This is not just a Migration Assistant issue, really, the file is completely non-portable via the standard available tooling today.

   I did not error on migration assistant to my new machine but now I am having the exact same error trying to boot orbstack on the new device.

   I was able to boot by completely removing the .orbstack/ folder
