A friend of mine recently dug a powermac pro out of the dumpster behind his apartment. (seriously! lol) He gave it to me to mess around with, so I plugged it in, and surprisingly it boots up fine. Of course, it boots right into a log in screen, and there's no "guest" option, and I have no clue if there's any way to get into this thing. I can't even tell what year it is, but it looks a lot like this: https://skozfilms.files.wordpress.com/2011/04/macpro-case-mock2.jpg except the ports in the back are in a different order, only has 1 cd drive, and the power plugs in near the bottom of the back panel, not the top. Is there any way to bypass the log in screen? Do I need to somehow install a new version of (power) OS X? is that even available anymore? Should I just return this thing to the trash heap?
