Looking for assistance reinstalling Mac OS on a ~2012 iMac
I cleared the disk utility on my dad's old iMac and now I'm struggling to get a new OS installed on it. So far I've tried the following:
- When I try to install the OS through masOS Utilities I get the following error "The recovery server couldn't be contacted"
- I made sure I was connected to wifi
- I also opened terminal and ran a prompt to ensure the date/time is correct
- I've tried Recovery mode (Command + R upon opening the computer) and selected the Recovery disk option but it never loads. I just get a white screen with the Apple logo
- I've also tried (Option key only upon opening the computer) and had no luck
- I've tried Internet Recovery mode (Option/Alt + Command + R upon opening the computer). After connecting to wifi the globe spins for a while and then I get the following error: -21 06F
- I've tried opening in Safety Mode but the computer never actually puts up when I try this method. I get the loading bar under the Apple logo and even when it goes to completion it never transitions from that page
- I've reset my PRAM/NVRAM using (Command + Option + P + R) and no luck
Currently the iMac simply opens and will load indefinitely but has no working OS so its a desk ornament for now. Everything has been transferred over and my dad has a new iMac but I'm trying to see if I can salvage this one so curious to see if anyone has any suggestions on how I can proceed. I also can't locate the original CDs that came with this iMac so I can't install the OS using that route if that is even possible.
