Hello,

So my sister gave me an iMac Late 2011 (OS X Yosemite 10.10). I erased the drive without backups then proceed to Reinstall MacOS, connected to the internet then clicked continue. Then there's an error showing up (A required download is missing). I can't get past this tried connecting to different wifi, etc. Now I'm stuck without macOS on my iMac.

I was wondering what are my options. Please guide me and if you got any questions please feel free to reply. Thank you!

It's not a good idea to erase the internal drive without a backup... (sigh)
But I guess you found that out already.

Try this (in the EXACT ORDER presented)

1. Boot to internet recovery (command-OPTION-R at boot)

2. Open terminal and enter this command to "set your clock back":
date 010112002019
(there is a space character between "date" and the number)

3. Quit terminal and REBOOT TO INTERNET RECOVERY ALL OVER AGAIN.

4. NOW try erasing the drive and then running the OS installer.

5. Does the install go through? Good, but remember to set date & time later on.

EDIT: I'm gonna give this a try. I'm just waiting for internet recovery to download files (first boot). Will update later.

I don’t think that will work – in my experience, restarting the computer to Internet recovery will automatically set the date and time again. Every reboot seems to set the time before an OS is installed.

Also, since Yosemite is no longer available to download from the Mac App Store, I personally doubt Internet recovery will work at all.

Do you have access to another Mac? Making a bootable USB install drive is the way to go.

Thanks for the help guys! I've already resolved this by using Internet Recovery and Ethernet cable connected directly to my Mac.

Yes, we can help you. Start a new thread in the iMac section.

I’m having problems similar to this topic and need help with my MacBook Pro. This is my first time on this site, so I’m not sure how to start a new thread.

Click forum, scroll down until you see iMac under desktops. Click new thread.
Wondering if you have any advice on issue? Thanks!
