how to install macos from usb flash drive

The process of burning can last from 1 to up to 30 minutes depending on your drive and on the iso file. The drive can be reformatted and used as a normal drive again after the setup is finished. When I tried using an SSD, and SuperDuper to clone Monterey (Apple Silicon), that time, it DID 'go right through' withtout a blip and produced a bootable cloned backup.Warning: All data on the drive will be destroyed. I'm guessing that Apple's installers have become much more 'picky' about what KIND of devices they will install onto. I then tried wiping the drive and doing a clean OS install onto it from 'recovery', and again, the install failed.

CCC would proceed, but would also protest that the target device was 'Too slow'. I tried using clone utilities to do a clone onto the drive, it wouldn't clone the OS over. I used it because at the time it was the only spare drive I had around. To wit, I had an old 40-pin ATA drive in a USB2 enclosure. I had a similar experience with my new MacBook Pro 14', and found that the 'drive requirements' may now be even more restrictive with Apple Silicon. Yet when I tried installing Monterey onto an external SSD, the install 'went right through'. When Monterey first came out, I tried installing it onto a flash drive. Not a 'real' hard drive that is governed by a controller board, but (taking him at his word) onto a USB flash drive that may have some circuitry to get it to work with a USB bus, but not a full-fledged drive controller board. The OP seems to be trying to install the OS onto a USB flash drive. So what am I missing, how can I install and boot the macOS from an external drive on the 2022 M2 MacBook Pro 13'? After many hours of downloading the installer and installing to the drive it rebooted and got stuck in another reboot loop. Last, I completely erased the USB drive with only one partition( APFS ) and booted in Recovery Mode and chose to reinstall the macOS with the USB drive as the destination. I rebooted and erased the APFS partition and ran the installer again, same error. It booted from the USB drive and I started the install, but at the very end( after a few hours ) of the install it says the installer is corrupt. Next, I tried the createinstallmedia command to a partition( 20GB ) on the USB drive with the rest of the drive partitioned APFS for the install. When I woke up I think the Mac had booted in recovery mode. That got me stuck in a reboot loop for hours( I feel asleep ). Then I opened the installer and chose the USB flash drive as the install location, it copied over all the files and rebooted.

That failed to verify the installer, so I trashed the installer and re-downloaded it. I'm trying to install macOS Monterey to a 1TB external USB-C flash drive, but nothing I do seems to work.įirst, I downloaded the macOS Monterey installer( latest )via the Appstore/Software Update.
