.DMG file extension?

I think only the very new Macs (Intel) can boot from USB. I really think you've got bugger-all chance of booting from USB on anything that's running OS 9. Sorry. Hopefully I'm wrong though. 😱

DMG works on OS 9

No. MacOS 9.2 and earlier versions of the MacOS understand *.img files. They also understand *.smi (self-mounting image) files. The *.dmg format is exclusive to MacOS X.

Just as an update: I have OS 9.2.2 on one of my project machines. I am not sure if this is new to .2.2, but you can upgrade free anyway. You can mount DMG images if you open Disk Copy and drag the image onto Disk Copy. You can then burn that image. Too bad my oldiMac doesn't have a CD burner.

Honestly - people like to make things complicated here. DMGs are the way we install apps on Macs (at least 90% of the time) so just forget all you've learned on the PC, double-click on the DMG and drag the application to the 'Applications' folder

Although to confirm this you might want to tell us what it is you're trying to install, just in case it's one of the apps involving a package installer

If anybody wants to make a .dmg file a .iso file to burn in windows. You must first search google for a program called dmg2iso. This program requires a little command work because it does not have a GUI. But it is simple and and a small file that does the job perfectly.

Nah... I know this is an old thread, but just want to say you could be lucky with USB... some old Macs unofficially supported booting from USB... I booted my Pismo from a USB (USB1.1, mind you) several times... I was using an early version of OS X at the time, but the Pismo definitively could boot into OS 9, too... 🙂

I would test it somehow before depending on it, though... and it would probably be a slow solution...

Interesting. I wonder if any of the Macs with USB 2 can do it. 😎
