An error occurred while loading the installer resources

Hello. I've been having an issue with all the Macbooks Pro (2019) I've tried to reinstall the OS while using the any kind of recovery. They came shipped with Catalina, but there are some cases in which I need to reinstall the OS and I always get this error. Cmd+R and Cmd+Opt+Shift+R both show me the recovery for installing Catalina once again, and so does Cmd+Opt+R. The problem is that, after I wipe the disk and format it using APFS and GUID partition table, and I click on Reinstall macOS, sometimes I get a "Downloader information to the target volume failed". After a few tries (and switching network) they usually get past that and start the installation process, but when it gets to 90% approx, they restart and show me this message saying "An error occurred while loading the installer resources". I have to keep trying (same process) until I finally get to the black screen with Apple logo saying 'X minutes remaining', but it works once every 20 tries or so. I checked date and time and they are correct, tried in other networks, same issue. Some colleagues have faced the same issue. Is this maybe something server-related that fails some kind of verification during the installations process? Any heads up would be appreciated, thanks in advance :(

MacBook Pro 15″, macOS 10.15

Yeah that's what I'm worried maybe hardware issue. Right now I'm being constantly stuck at the downloading target volume error.

Also, do u keep clicking reinstall macos or u restart and then do it after the downloading installer error?

I can't boot USB since t2 settings ask for authentication to change boot settings. I'm unable to do that since it asks for authentication and says no admin found.

I guess the only option left is to try resetting the t2 firmware. I'm not sure what's wrong. I'm super worried.

Anyways. Thanks for your assistance. Appreciate it

Yes, after repeating the process several times, one of those tries ended up working. Most likely, it will work at night (for some reason)

Oct 6, 2020 9:28 AM in response to HWTech

Are you sure this could be a hardware issue? It's a brand new Mac and it was working all well before the os was erased

Try connecting your Mac directly to the router using an Ethernet cable and a USB to Ethernet Adapter just in case you have some sort of networking/WiFi issue.

If you have access to another Mac then create a bootable macOS USB installer:

You may need to boot into Recovery Mode to modify the security settings to enable booting from a USB drive:

Edit: Also make sure to erase the whole physical drive as described in this article:

Thank you.

Yes, all of them and I even tried with the First Aid Utility and it keeps happening :( even I tried copying files while on Recovery mode to different volumes to force the installation to start after a restart and nope.

I think, as you said, it’s something related to the firmware. It’s probably not being updated while starting internet recovery. Also, considering they’re all new MacBooks, it shouldn’t be a hardware issue. I also called Apple Support and they told me all the MacBooks probably came with a hardware issue and that I should take them all to an Apple Store which clearly, doesn’t make any sense at all. That’s why I kept trying and trying until one of those attempts worked. Doing the exact same process.

The only thing I haven’t tried yet is trying with “Get Help online”. I’m gonna check that out and see what happens. Thank you again :)

They are not very helpful. I called asking for a solution to this because it has happened in every single MBP that I tried to reinstall and they told me to take every single one of them to Apple Support. That is not a solution when clearly something is going on with the installer itself (and I can’t imagine taking at least 8 devices to Apple support because of the same error).

I had to be patient and continue trying, repeating the same process, erasing the disk and reinstalling until it finally worked.

I haven’t tried the T2 procedure, but from my experience with all these Macs, most likely, it is not a hardware issue.

I mean, what are the chances of the same issue happening on at least 10 different (and new) MBP 2019? 👀
