The primary reason for me deleting this was that I considered it unanswerable in its current form - I figured it would be deleted anyway.
For the record, this is the question as it was
What I see?
"I'm trying to install osx yosemite from a .app package that I downloaded from a torrent."
Uh huh, outright piracy, and of course, not enough information for us to determine if his download was at fault.
"Once I reach this stage, it asks for the root password but never moves forward. Any suggestions?"
No actual attempt at troubleshooting - no error messages. No real clue for anyone what is happening.
In short, I had the option of putting on hold (And I tend to prefer this in most cases), or putting a clearly low quality question with many issues out of its misery as soon as possible.
I went with the latter. Really, 2 lines and a generic question do not make a quality question, and it didn't seem worth salvaging.
However, there's always a recourse.
Include detailed hardware and pre install software information. THIS alone might have saved the question.
A legitimate source so we can rule out the download being faulty. I'd probably consider leaving out the fact that its torrented, and including the fact that its been checked against the official version's hash.
More details on error messages - how dosen't it move forward? Does it beachball and go back to the same screen? Does it do nothing?
Once you have a question with the bare minimum of required details, flag for undeletion. We can do that.
