I downloaded an iso and was supposed to dd it to my USB drive. You can see where this is leading, but it’s worse than you think.
I overwrote the hdd. While I was on an airplane. Of a macbook air that I had no idea how to restore to a functioning state. And this was my workplace laptop.
Like I said, dumb on many levels…
Edit: while the question is about breaking ones Linux installation, one could argue that macOS share the same lineage as Linux and share many similarities.
