Error Occurred While Preparing the Installation Try Running This Application Again
- #i
When upgrading from Big Sur 11.half-dozen to Monterey, the software update launches an installer app which goes through the preparing progress bar prior to restart. At the betoken where information technology says "closing applications and preparing to restart…" there's a popup maxim "An error occurred while preparing the installation. Effort running the application once again."
Running the installer again fails at this step. Rebooting, resetting SMC, erasing and re-downloading the installer all do not set the problem. The date and time are accurate. Disk Utility offset aid doesn't make any changes and skips over repairs. Has anyone managed to detect a solution to this problem?

I made a boot drive in terminal and booted into the installation media that way. After the first run of the installation process, I got an error that said "A required firmware update could not exist installed. Compatible internal storage is required in order to update." Probably happened because I upgraded from a 1tb SSD that came with the laptop to a Apple Polaris 2TB from an iMac. I'm running a 2015 MacBook Pro.
It makes it doubtable that it can possibly be the same error occurring while still logged into the previous installation.

Mmmmm...that'south slightly worrying. I also replaced my SSD a while dorsum, although i haven't got as far every bit making kicking drives and stuff.

Having the same problem with iMac 2017. Original iMac come up with Fusion (32GB SSD + 1TB HDD). I replace SSD with bulldoze from other macbook. While many people using Syntech adapter to place whatever NVME, i was using original Apple drive, without adapter. Now cannot install Monterey, stuck on Firmware update. Was using pick "--downloadassets", simply information technology did non aid. Funny, i was trying to install Monterey Beta, merely that time was hit with message "unable to verify firmware". So i judge apple include some checking mechanism to see if all hardware is original.

I am having the exact same trouble on a MacPro 2013 where I replace the SSD for 2TB

Ok so going through some forums, I've seen two supposed fixes. Firstly, "Turn off networking". Not sure why that would change annihilation, but it'southward worth a try.
2nd affair I constitute was "uninstall any software that makes use of and installs kernel extensions. Examples of these are Parallels, Intel CPU gadget, and Trivial Snitch". I actually have ii out of 3 of those, and so permit me give it try and i'll come up dorsum with some info.

Same issue on 2013 Mac Pro with a replaced SSD... the sometime SSD is cleaved. I used a non-OEM SSD with an M.2 adapter since Apple doesn't sell replacement parts for this.

try Hackintosh methods with OpenCore or wait for 12.i.... 😞

I'll wait and see, I just hope Apple doesn't consider this a "characteristic".

You can bet they practise... It does not hurt to ask hither: https://www.tonymacx86.com

I spoke to OWC tech back up, their workaround is that if you can reinstall the original Apple tree-supplied drive and so install Monterey on it, and then it volition update the EFI firmware for the device and so you can install Monterey on your Big Sur volume. It seems this is also mentioned on Apple tree support thread as a successful solution.
Unfortunately any mess that happened so far with the Monterey installer failure has deleted my recovery partition and fabricated the network recovery unable to come across my drives. It looks like I'm going to have exercise get some hardware to gear up this, and of grade Apple has stopped all genius bar appointments.

Hmm I have two of the Mac Pro trashcans from OWC with SAME config and ane upgraded and one did not. This is non cool. But at to the lowest degree it did not toast the configuration like the Catalina upgrade.

So I guess another question is does it accept to be *the* original drive or just *an* original bulldoze? I tin get what looks similar some salvaged 256gb OEM trashcan drives off eBay for $30.

I swapped imac 2017 SSD (32GB) with SSD from macbook 2016 (512GB) both apple original. I am not using Syntech adapter. Still does not work.

This one has nothing to do with that. Apple with Monterey failed to install BridgeOS, if SSD is not original. Peradventure they will fix it in the hereafter. I was trying to update it manualy from Mojave, or BigSur, simply it did not piece of work.

I have a Macbook Pro, Retina, 15 inch, Mid 2015 with a 2.8Ghz quad cadre Intel Core i7, 16GB RAM and a 2TB disk I think is original. It fails the install with the same error as above "An mistake occurred while preparing the installation. Try running the application again."
The hard drive is listed as Aura Pro X2, media proper noun AppleAPFSmedia
Tried twice, downloading a new re-create of monterey and reinstalling. No joy. Not sure where to get from here...

Your drive was upgraded with OWC! It is non the original.

This is a ridiculous effect that Apple should take addressed before this OS release. Changing to the original SSD does fix the failure to load firmware issue. And, it's clear that the firmware issue has zip to practice with whether Monterey will ultimately work with SSD's other than the original. Later putting back my original SSD Monterey loaded flawlessly from a bootable flash drive. I then put back the upgraded larger SSD that had failed every time giving the "could not gear up" or the "could not load firmware" messages. Having downloaded the Monterey installer to that Hard disk drive, I booted up property the option key, chose the Monterey installer and the installation proceeded from where it had failed all those previous times with out a hitch. The firmware update must have to practise with a controller or something other than the SSD. Anyhow, after much frustration Monterey is up and running on my 2013 Mac Pro. Thanks for all your aid everyone. Couldn't accept done it without yous.
