Make a Monterey Bootable USB installer!

[Mike Boreham]

Thanks, understand.

Since it seems likely that Apple will rectify this I will wait for now, though I appear to have a working bootable installer if needed. The font messages make me uneasy.

Out of curiosity I used creatinstallmedia from the Terminal using the same full size Install Assistant I had assembled above, and it worked as normal.....no messages about fonts which MDS gave me.

I'm getting a "damaged installer" error when I try this workaround. I extracted SharedSupport.dmg using Pacifist, created a folder called SharedSupport and copied the DMG into there.

Not sure what I'm missing – I confirmed that the permissions for the SharedSupport folder and DMG are read and write.

I'm getting the same error and have gone back to macOS Big Sur until Apple provides a full Montery beta 7 installer.

Maybe the MDS method might work better than extracting from InstallAssistant.pkg.

Either way apple are making it pretty hard to make a bootable usb of beta 7 now.

Createinstallmedia was supposed to make it easy. Now it doesn't even work unless you "fix" the installer.

Hope this is unique to this beta otherwise very few people will make bootable usbs in the future. I've always had a bootable something since mac os 7. You hardly ever use it - but when you need to, you are glad you had it.

I ran through the process using the MDS process and I was able to boot from the USB drive and install the update from there. Hopefully, the next release pulls down the delta OTA as it normally does.

Yesterday beta 8 was released to developers, build 21A5534d, but no full installer. Today the same build was released to public beta testers and they can also get the full installer - but still not developers.

So at the moment if you want to make a bootable usb of beta 8, download the public beta build 21A5534d.

They have also fixed the SharedSupport problem this time.

Hopefully the full beta 8 installer will be released soon to developers so that they don't have to download the public beta.

The full installer for beta 8 is available to developers now too, so no need to download the public beta anymore.

Hopefully the full beta 8 installer will be released soon to developers so that they don't have to download the public beta.

Surely, the public beta update is the same as the developer update (just released a day later) with their being just one common full installer.

Yeah they are basically the same, but public beta testers got the full installer a bit before developers. So in between the only way developers could get the full installer was to download the public beta.

Looks good to me. mrmacintosh has the same command I predicted in the first post in this thread

sudo /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

so the only change is the word beta is removed now.

It works. I made a bootable usb using this command yesterday.

OK, the thumbdrive I made seems like it should work but Mojave does not see it as bootable. I ended up installing onto an external SSD and it works like a charm by just using the downloaded Monterey Install file directly.
