That title does not give a good impression, but I've watched the first minute (don't have more time gotta go to work) and it seems like it's a somewhat serious video.
I was able to find a forum post from someone experiencing a similar issue from back in 2014. It seems like they don't give out any information until the end of the investigation. I'm guessing it's probably CSAM.
I used QEMU but I don't think it's possible anymore. I had to use an older version of OSX (I think I tried 3-4) but that version is no longer supported by XCode.
Yes, and the worst part is that XCode is only available on OSX.
I once had to make an iOS app once and didn't have a Mac so I developed the entire thing in a VM. There was no video encoding, the FPS was in the low single digits, which made it very difficult to even type. So I ended up writing the code using VSCode through SSH through Wireguard connected to the VM on the host machine, which actually worked surprisingly well. But hey, the app did work in the end.
