This saved my day!! I have a late-model 1.67GHz Powerbook which was ruined beyond Disk Utility's reach, due to a frozen OS update that forced me to power down. I have no Firewire drives, Time Machine backup, blank DVDs, etc. All I had was a Leopard DMG sitting on my windows box and a 8GB USB drive laying around. I was successfully able to use this method to restore my computer and sanity!Here are some tidbits from my experience:-The USB had to be formatted as MACOS Extended, not Journaled. Otherwise, I only had 6.4GB usable space for a 6.7GB DMG file.-The restore step took about 20min for me, as did the OS installation (trimmed of language and printer driver options)-For me, the location of the bootable USB was /pci@f2000000/usb@15,1/disk@1. I mention this because the ",1" was easy to miss on my machine and was needed.-The BootX location provided in this post was spot-on for my 10.5.6 image.I can't thank you enough for the time and hassle you saved me! Also, it was fun using OF mode for the second time.
hey guys!!!! after a few tries, I FOUND A SOLUTION. my powermac G5 is now on the nice 10.5.6 :)))HERE'S A GUIDE FOR ALL THOSE OF YOU, WHO ARE STILL STUCK WITH THE GUIDE ABOVE:1. if you are completly new and have no torrent downloader, download vuze. its a nice, small, free torrent downloader and it works :)2. after that, you have to download the iso file. i chose the one on www.picktorrent.com/download/b7/173126/mac-os-x-leopard-10.5.6-full-retail/it should work...if everything is done, a folder "vuze downloads" should appear on documents. open it and go to mac os x install dvd. inside should be a dmg file.3. plug your USB stick (8GB, better more) into the computer. the file system should be set to MAC OS X EXTENDED (NOT journaled) 4. follow the guide above from step 3 til step 8.5. you're now in open firmware. type in dev / ls and a list with all files will appear. press space to scroll down. now, you have a tree structure, you have to choose the leftest and go to right and bottom, till you reach /usb@b/disk@2(it don't have to be exactly like that)then write down the whole path(in my case ht@0,f2000000/pci@8/usb@b/disk@2)6. write devalias into the command prompt. it should appear a list. you have to search the USB. (in my case USB2,USB3,USB1a,USB1b,USB1c) then I guessed that it would be USB2. my choice was the right, if your one isn't the right it will nothing happen in step 7.7. type dir (name_found_in_step_6)/(disk_name_found_in_step_5) :(partition_number_found_in_step_7_of_the_guide_above),\System\Library\CoreServices (in my case dir usb2/disk@2:10,\System\Library\CoreServices)8. now a list should appear with the programs inside this folder. if a program with the name BootX and the atribute tbxi is there, you're almost done. type in boot (name_found_in_step_6)/(disk_name_found_in_step_5) :(partition_number_found_in_step_7_of_the_guide_above),\System\Library\CoreServices\BootX9. press enter. the installation should now begin.10. ENJOY YOUR FREE LEOPARD!!!!! :Dso it worked for me. i hope for you, too and for questions just ask me: fritzmeier83@gmail.com(PS: sorry for my bad english, i'm from switzerland :)
Mac OS X Leopard 10.5.6 FULL Retail DVD Bootable ISOl |WORK|
Upon booting the first time the graphics were sluggish and it could only run at 10204x768. There are a number of posts on the topic of video drivers, the problem is some of them are dated. NVinject worked for my 10.5.2 Kalyway install, but did not work for the 10.5.6 retail. Instead I had to use EFI Studio (found in the v4.4 package from earlier) and selected the 8600 GT 512 MB item. Then I clicked "Add Device" which brought up this window:
A flashing question mark does not necessarily mean the drive is bad -- it can just mean it's not bootable. And a new drive is not going to be in Mac format anyway, and is going to need to be formatted via Disk Utility when you get to the screen where you're asked to select the disk to install to (on that screen, pull down the menu from above and choose Disk Utility). And since your old drive is supposedly bad, and you are likely booting with the wrong OS media (which often won't fully boot), I wouldn't panic until you get the DVD from Apple and that doesn't work either. Also, I assume you have at least 512MB in there (minimum requirement for Leopard)?
If you had a retail box version Leopard install discs handy, they could be 10.5(.0), 10.5.1, 10.5.4, or 10.5.6, because Apple periodically updated the version of Leopard in the retail box. If your Leopard retail box contained 10.5 or 10.5.1, it wouldn't install on your Early 2008 MacBook. If it contained 10.5.4 or 10.5.6, it would work. 2ff7e9595c
