Shortcut for installing OS-X on unsupported-? |

Is it possible to install OS-X onto a SCSI drive in a supported machine such as the beige G3 (?) or other Mac which supports internal SCSI, then take that drive and pop it in a 7300 (or similar)? Or does something occur on the host machine hardware separate from what is installed on the hard drive? OR, instead of using a SCSI drive, install OS-X on a G4's IDE drive as normal, then make a clone of the system onto a FireWire drive using one of the copy utilities, after which it can be again cloned onto the Old World machine? If either approach could actually be done successfully, we can skip a lot of trickery ;-). |

For the most part, the Mac OS X Installer appears to install the same thing onto a drive no matter which computer it is running on (there are some exceptions, like the iDVD software). So it does work to take a Mac OS X drive from a supported machine and put it in an unsupported machine, so long as you use XPostFacto to start up. (XPostFacto will notice that the kernel extensions required for older machines aren't there, and install them. It will also automatically install a customized version of BootX). I'm not sure whether cloning from a Firewire drive would work. It does work with Carbon Copy Cloner, but if you could use that, then you would have Mac OS X installed already. In theory, Apple Software Restore might do the job, but I vaguely remember that there was some problem with it when using a Firewire drive (I might be wrong). But in the ordinary case, using XPostFacto to do the install from the CD is simpler than this alternative. (Of course, it isn't always the ordinary case). |

Worldalex, please give us some details about your procedure. Did you install XPF after you moved the installed system drive to your 7500? I assume so. What (if any) boot up issues did you have with this arrangement? If none, it sounds like this approach may be the simplest way to go. I'd also like to hear from those who installed onto ATA drives and used some other means besides physical drive swapping to get the install into an older SCSI -based machine. I have access to labs full of G4s, but only some beige G3s with SCSI capability (nothing inbetween). As for the Sonnet software, does it work with XLR8 cards? I recently went and sold a couple of Sonnets on ebay without thinking about eventually doing the X upgrade test! |

I have used my Blue and White to install "X" on a SCSI drive and then moved it to my 7500 where I used X-Postfacto to install the necessary kernel extensions. Without X-Postfacto, even with a good install of OSX an unsupported machine will not boot. Then again, you could also use the Sonnet software. |
