Select Leopard Install DVD I have been beating my head against the wall about this but luckily only for about 2 hours today, LOL! I read about this little fakeout prior to today, when I actually decided to try to install on my G4 Silver w/PPC@500mhz & 1GB/RAM & an old ass ATI Rage128 w/32mb, yikes!

So I spent the better half of the night trying to figure out how to make my iBook G4 boot from a USB stick. I have the Leopard ISO, but none of my DVD drives will burn Dual Layer, so I needed to use the USB route.However, none of the nonsense I found on the Internet could give me proper instructions. The system itself doesn't directly support it (holding down option during power-on doesn't show it either).So I had to dig into my OpenFirmware roots and do it the old fashion way.

So here's the quick tip for the rest of you out there (hopefully Google will eventually pull this up in page ranks so it gets hit first and saves people time). Plug in the USB device where you have copied your bootable system to (I do not cover this part since it's well covered already, google is your friend). Power on your iBook and hold down Command+Option+O+F. This will take you into the OpenFirmware. Scary looking if your not a computer type person. Once you see the screen go white with some text on it, you can release the keys in the previous step.

Type ' boot ud:,:tbxi' and if you're lucky, it will start booting from your USB device. If not, continue on. Type ' dev usb0' at the little ' prompt and hit return. Type ' ls'. If you see something like ' /disk@1', continue, else go to the previous step and use ' usb1' instead.

If you get here and you haven't seen something like ' /disk@1', then you're likely screwed, sorry. Type ' dev disk@1' and hit return, and then ' pwd' and hit return again. You should see something that looks like ' /pci@f2000000/usb1b,1/disk@1'. You will use this in the next step. Type ' boot /pci@f2000000/usb1b,1/disk@1:,:tbxi'. This is the device part you got in the last step after typing ' pwd' with ':,:tbxi' added to the end. Moment of truth, hit enter.

You should now be booting into your USB drive. IT WILL BE SLOW SO BE PATIENTThis should also work on other PPC Mac's that don't normally boot from USB, such as G3s.

FredBen, I hope you can help me, man! I just got an Ibook G4 40GB HD, 256MB RAM from a friend and the OSX installed doesn't come up.just stuck on the white screen with the apple logo in grey and a loading bar on it.ah, there is another problem too, the CD-ROM is not working properly, when you put the disc in, it's ejecting right after.I have tried with many different kinds of medias and no lucky with none.so, the problem is the CD-ROm.so, my question is, there is a way to install or create a bootable OS in a USB stick and then start the system from it.? I am searched on google for a long time (about 1 month already) and no lucky.so, if anyone has a solution for that, please, send me an e-mail: freder.holland@gmail.comI've downloaded the OSx Panther and Tiger, but there is no way to burn and try on the iBook because the CD-Rom is damage.so, my last hope is the USB port to revive this 'old boy'.lol.Thank you very much, and sorry for the long text:PFred.

AnonymousHello there,First of all, thank you for the method. Unfortunately, I'm having a hard time with the 'Warning: sector size mismatch! Can't OPEN: usb1/disk@1:1,:tbxi' error.- I used 'dev / ls' to locate the disk, and it appears it is effectively mounted as 'disk@1' on 'usb@1b'- I used DEVALIAS to see the disk alias for 'usb@1b', and it appears it really is 'usb1'- The partition number appears to be '1'- I tried every single method listed in here, none of which worked (always getting this error, or 'partition not found' etc if I try other values)If somebody had a solution for that problem, I would be infinitely grateful.-. AnonymousHello everyone. Since I have this PowerBook G4 1.67GHz and 1Gb RAM old laptop with no main battery, with dead internal PRAM battery (I guess) and most importantly with a faulty DVD drive that works only now and then before it heats up and stops, I decided to try the instructions on this blog. I used an external LG DVD drive instead of a USB stick.

The laptop already had OS X 10.5.8 on it so I decided to try to install either Ubuntu 10.04 PPC Lucid Lynx or Yellow Dog Linux 6.1 PPC, both well known to work (except Airport card that has to have its driver compiled and manually configured) on most PPC Macs. Conclusions: for this particular PowerBook G4 the only command that works to boot from the external USB DVD drive was:boot /pci@f2000000/usb@1b/disk@1:3,:tbxiThis command opens the installer disc and installs properly OS X 10.5.1 from the original dvd disc that I have. On the other hand, when I tried to open the installer disc for both linux versions I wanted to try to install, the command worked in the way of opening the disc on the external USB DVD drive (I could hear it spinning) but I got the message that cd:yabootinstall cannot be opened (yaboot is the bootloader used for ppc versions of linux). It may work directly from a USB stick but I decided not to try to compile the installer on a USB stick. At least I know that if I'll ever have to reinstall OS X I will be able to do it from an external USB DVD drive. Last mention: the external drive must be also plugged-in in its external power supply (either the 12V one for the big 5.25 inches drives or the 5V one for external slim DVD drives). Just ran into some of the same problems as others seeing the 'Prohibitory' symbol (circle with line through it) while booting from a USB stick.

Use these tips to create a proper USB stick:In Disk Utility, select the USB device and then the Partition tab. Create a new GUID partition with 1 partition (HFS).

After this, select the.dmg for the MacOS X install and select the Restore tab. Next, drag the new partition you created to Destination (not the USB device itself).The Prohibitory sign is because it cannot find the root filesystem (if you boot with Single-User/Command+S, you will see it saying 'Still waiting for root device.' ).This is true for all versions of Mac OS X, not just the PowerPC versions. I had this issue on my MacBook Pro/Intel system as well. AnonymousHi, I just got an old G4 PowerPC (733MHz) from my dad and want to install the latest version on OSX using open firmware. I have mountain lion on a usb thumb drive but when I press Alt to see boot devices and can only see the hard drive. I followed your instructions to open firmware but I get the following problem.0 dev usb1 ok0 lsff9c7f8: /disk@1 ok0 dev disk@1 ok0 pwd /pci@f2000000/usb@19/disk@1 ok0 boot /pci@f2000000/usb@19/disk@1:,:tbxi can't OPEN: /pci@f2000000/usb@19/disk@1:,:tbxiCan you please help me as I really want to try and use this machine as this is my first mac.

Also I tried to get DIR on disk@1 but it looks scrambled a bit./pci. LukeI tried seemingly everything, and on my best attempts I was still getting 'sector size mismatch'.

Finally, on what seemed like attempt #200, I stumbled upon my solution. Using, disk utility, I went again into the partition tab. There, I finally, noticed and clicked on the 'options' button below the partition graphic. In there, it had been set to a MBR partition table. I changed it to 'Apple Partition Map'. Then I set it up with the one partition again, and saved that.

Next, again I went to the restore tab and transferred over my bootable partition (or possibly your image) to the partition just created. The next attempt to boot with the method beautifully described here didn't give me the mismatch error, but instead began booting with the apple logo! Sadly, it shortly went to the circle with the slash through it, and I thought I was still stuck. Continuing my insane attempts, I tried holding option from a cold boot and was, surprise of all surprises, able to see my usb partition, select it, and boot it fully! Thanks to everyone for the suggestions, not least Ben for the initial writeup that spurred the discussion! Hi I have iBook g4 mid 2005 and I have a.DMG of 10.5.8I restored my flash drive with the DMG then booted the iBook with the USB drive.

When I did that the iBook treated my flash drive as the main hard drive and if I am to remove the flash drive the computer will not operate as a restored computer. Autodwg dwg to pdf converter keygen crack mac. So I keep the flash drive in. I was told to open the flash drive and then hit install is x 10.5.8 but that's not even an option in the flash drive at all its just a bunch of folders as you'd see on Mac such as 'applications'Etc.So I thought maybe use the drive to restore the Mac HD but nothing happened Mac HD is now called untitled and the computer doesn't even want to boot up at all without the flash drive.Any help appreciated. AnonymousSometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime.

Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:reset-nvramset-defaultsreset-all.

If you have recently upgraded or replaced the hard drive for your MacBook or iMac, you will need to reinstall macOS onto it. This guide will show you how to install macOS High Sierra onto a blank hard drive.Note: This guide is untested for macOS Catalina, and will probably not work without adjustments.Before you begin, you will need to create a bootable flash drive. This requires having access to a Mac currently running High Sierra, in order to download the 7.7 GB High Sierra file in the App Store. You will also need an empty flash drive that can fit 5.4 GB.before proceeding with the guide.
