I am not, nor is anyone else, responsible for any potential data loss. Once you figure out which device the USB drive was mapped to, unmount it ( disk2 is the device in this example, your device will probably be different): diskutil unmountDisk /dev/disk2Ĭopy the Contents of the Ubuntu ISO to the USB Driveĭisclaimer: The following steps will erase everything on your USB drive. Open Terminal and run the following command to figure out which device the USB drive was mapped to: diskutil list Next, plug your USB drive into your Mac it will automatically be mounted by OS X. Start by downloading the Ubuntu ISO you want to boot from. You can simply download the Ubuntu ISO and use dd to copy it to a USB drive. I am happy to say the G4 is now chugging along on a copy of 10.5.8, albeit a bit slowly and with animations disabled.Ubuntu has a great set of instructions on creating a bootable USB drive in Mac OS X, but they have an additional step I found not to be needed: there’s no need to convert the Ubuntu ISO to an IMG file. I ended up buying a Leopard CD, making a USB installer out of it, and using an externally powered USB hub to circumvent this lacking power draw. As for the Panther CD I never did figure out why it wouldn't boot, however I did discover the reason the Panther USB hung at the "Still waiting for root" screen is because the USB drive had insufficient power to act as a boot drive when plugged into the Mac's USB ports.
UPDATE: To those reading this out of curiosity or to perform the process yourselves, I found that my Tiger CD was corrupted, thus was the image as well, which explains why it was unable to read part way through the boot process. I am almost certain the problem is with the way I am making the installer (ripping ISO via Disk Utility, and burning to USB via dcfldd or dd). Yes I am sure they're genuine, and I have already tried that. In the past I have successfully installed Mac OS 9.2 via USB on this machine, however 10.3 always begins the boot process, only to hang on the "Still waiting for root" screen (White background, grey prohibitive logo), and 10.4 always gets as far as the Apple boot logo, only to hang there and stop accessing the USB drive all together.Īny help is appreciated, but please skip the generic "Are you sure it's a genuine CD?" and "Try resetting the PRAM/NVRAM/SMC". So my question is: how would one make a bootable Mac OS X 10.3/10.4 USB install disk(s) using self-made rips of the CDs? The catch is that for several reasons I am unable to use the CD drive to perform this installation, and am thusly relegated to using USB (I have no FireWire drives or other PPC Macs with which to perform a Target Mode install.). I would like to either reinstall Panther, or upgrade to Tiger. I have a PowerMac G4 (AGP) with a working copy of Mac OS 9.2, and a corrupted copy of OS X 10.3.
