Le Chuck Posted August 27, 2006 Share Posted August 27, 2006 Just downloaded the DMG of Leopard this week and try'd to install it on my G3 800Mhz iBook. I've done some searching in the installer to see what's supported and found that there's a check for G3 proc's. I've burned the image to DVD-R DL to make sure, and the installer give's an error message saying that my hardware isn't supported. After editing the installer it did install succesfully, and i will show how to edit the file. First convert the DMG to a read/write enabled DMG with the Disk Utility. Mount the converted DMG and edit /Volumes/Mac OS X Install DVD/System/Installation/Packages/OSInstall.mpkg/Contents/OSInstall.dist with tekstedit. In the top of the file there are a few lines who look like this: function checkSupportedMachine(machineType){ // Fail on G3 if (1 != system.sysctl('hw.vectorunit') ) { return false; } var badMachines = ['iMac','PowerBook1,1','PowerBook2,1', 'AAPL,Gossamer', 'AAPL,PowerMac G3', 'AAPL,PowerBook1998', 'AAPL,PowerBook1999']; if(machineType){ var length = badMachines.length; // Fail if any of the compatible values match the list of badMachines for( var j = 0; j < length; j++ ){ if(machineType == badMachines[j]){ return false; } } } // if we can't find it, assume it's supported return true; } Change these lines to just this: function checkSupportedMachine(machineType){ // if we can't find it, assume it's supported return true; } Then burn the DMG to a dual layer DVD and have fun! There are a few thing that don't work with a G3. Safari doesn't wan't to start and the prefspanel for Pages doesn't work. Safari can be enabled by copying it from a Tiger installation :-) I've just installed Leopard on a G4, and it does work very well on a G4. Please keep me updated with any error's and bugs you may find on a G3. Meanwhile, i'm enjoying the first iBook G3 with Leopard in the Netherlands Link to comment Share on other sites More sharing options...

Rhapsody Guru Posted August 27, 2006 Share Posted August 27, 2006 Well done! It seems that Apple wishes to do away with G3s, even though they are quite capable processors. This reminds me of a time when Steve Jobs tried to rid his company of the Apple II line of computers so as to pave the way for the Macintosh.

Guru Well can't blame Apple for getting rid of the G3 support. The G3 already last's for at least 8 years now and whe have intel proc's now My expectation is that PPC support will be off in Mac OS X 10.6 But now that i've got a G3 and a G4 running, it's time to crack Leopard for my P4 "mac's" Link to comment Share on other sites More sharing options...
linuxjerk Posted October 7, 2006 Share Posted October 7, 2006 Hmm..Kind of obvious and I know someone's down it a million times but just to confirm I installed Leopard on a G4 EXTERNAL firewire drive then just plugged it into my G3 800 iBook. Works fine, just as quick as Tiger. A couple of things dont work: Itunes - just used the Tiger version Safari - as above - or try Firefox Sound DOES work btw. So does Screens :-) (only 2 screens, you can't change it to more than 2 - I'm hunting for the conf file) Right now I'm installing on my GF's iMac DV 500 (call me a pervert if you want to...)

Alec S. Posted October 26, 2006 Share Posted October 26, 2006 I'm the owner of iBook G3 600 MHz (Late 2001).. And I'm very happy to know that Mac OS X "Leopard" can be started under this PowerPC G3!! I'll try it! Link to comment Share on other sites More sharing options...

trav1085 Posted December 30, 2006 Share Posted December 30, 2006 (edited) There isn't any "Show Package Contents" option for OSInstall.mpkg. Help? Edited December 30, 2006 by trav1085 Link to comment Share on other sites More sharing options...
Guest bikedude880 Posted December 30, 2006 Share Posted December 30, 2006 I can't select "Show package contents" in OSInstall.mpkg. There isn't any option too. Apple has implemented a new package design. They have compressed the packages using a utility called "xar". In order to modify the packages, you need to have 9a321 already installed. Quite the Catch-22, eh? Link to comment Share on other sites More sharing options...
trav1085 Posted December 30, 2006 Share Posted December 30, 2006 (edited) But... I don't have it installed, how can I if I need to edit this file so I can get it installed on my G3? Can I download xar? Hmm... Could somebody send me that edited file? Through my email or so. If asking here is against the rules I remove this.

dggraphics Posted June 25, 2007 Share Posted June 25, 2007 If you are having difficulty installing the OS you could use CarbonCopyCloner as another option. 1)Lock the Disk Image 2)Start Carbon Copy Cloner 3)Select the OS Install as the Source 4)Select a drive with enough free space to install the OS(Preferably not your Startup Drive-A Blank external drive would be best-An Old FireWire iPOd works very well for this) 5)Clone the Image 6)Make any changes to the install package you need to. 7)reboot off the external drive and install.

ARMAGEDDON Posted June 25, 2007 Share Posted June 25, 2007 On screenshot i see Toast 7 that cannot work on G3... And Screenshot didn't show any other leopard "things" that can identify this OS as Leopard. Just standart Dock, toolbar... And ATM with wrote 1.5... Any other facts to proof ??

xcuneytx Posted October 27, 2007 Share Posted October 27, 2007 i have an iBook G3 700MHz with running Tiger smoothly.. is it worth to upgrade to Leopard.. will it run smoothly as well? Link to comment Share on other sites More sharing options...
marcooleo Posted October 28, 2007 Share Posted October 28, 2007 I assumed this should work with a G4 with less sys req aswell. I tried but i only get´s garbled text when i open the file: "Install Mac OS X" with texteditor.. Maybe i did something wrong, i have converted the dmg to read/write and mount it. Can you please describe exactly how you did after that? Link to comment Share on other sites More sharing options...
