A Required Download Is Missing

I'm certain I've bricked my MacBook, but maybe someone can help!

I've just bought a new MBP and was going to sell the old one, a 2015 13 inch model. I was trying to erase my details for selling, and I believe I've deleted something I shouldn't have, while in disc utility

When trying to install a new OS I keep receiving an "A required download is missing" message, so can't go any further.

I've tried to repair the disc but I'm not getting any errors, and have also tried to get it going again using Time machine from another Mac, but gets around 90% of the way during the black screen with the white line then stops.

I've also tried to go via safe mode, on the off chance that offered something, but it wouldn't start that way.

I can't see there is anything I can do to solve this, as there are no other options available. But someone may surprise me.

Talked to an Apple specialist today and thought I'd post his answer in case anyone still has this issue. He had me restart my MacBook Pro and hold Command+Option+R until a spinning globe appears after the restart. He said this era of laptops' certificates for Mac OS X reinstalls have expired, so the option listed above drives the computer to search for essentially an updated reinstall certificate online. Hope this helps!

Just want to confirm you tried ‘option+cmd+R’ right after the boot up noise. This should take you to internet recovery mode.

Help please. How did you keep downloading? I keep getting the same error message and it is trying to install Lion. Ugh!

Cuurently, this appears to be a problem. Is it something Apple is doing to us. Not supporting El Capitan anymore?

I had the same exact problem

What you did worked for me too... my MacBook was down for almost a month

Thanks

Downloading installers from the pirate bay and not official apple sources would be a definate cause for any install issues, and absolutely bad advice.

Hi! I Have an old Mac Book Air 2011. I want to give it away. I tried reinstalling OS X Yosemite but get the following message “a required download is missing”. What can I do?

Given that my MacBook is in stuck state I assume you need another Mac to make a boot disc on a Flash drive or similar using Disk Maker X?

I think that you can make a bootable USB from a Windows computer too. I saw threads on this as I searched how to do it. YouTube is your friend here.
