Re: will a PPC cloned boot drive work as the boot drive for an Intel?

2009-07-28 Thread amorielljason







 

The PPC G5 was running 10.5 (.2 I believe).  I tried again.  It will boot from the cloned G5 drive on the external hard drive, but the mouse still fails to work after boot-up, regardless of which USB port I try.

I assume that's what the mini is using ... how about the PPC G5 whose
recovered install drive you were trying to boot from? What OS was it
using? (Just wondering if that external drive contained the version of
Tiger (or later) which supports Intel or an earlier Mac OS.

Thanks for the suggestion, but I'll wait. I'm still too new to the Mac
& to OS X and thus (obviously) too naive about the basics. I'm not
particularly squeezed for space at the moment so I'll stay with what
Apple has blessed rather than go out on a limb.

I'm just surprised that the universal binaries were used for OS X. It
appears that during the migration to the Intel Macs back circa 2006
that Apple essentially "bloated up" OS X by including binaries for
both CPUs. Now with the advent of Snow Leopard only the Intel binaries
will be installed and ... surprise!! ... the size of OS X suddenly
shrinks. Such technical genius!

The situation reminds me of those wonderful department store jewelry
sales offering you 30% off! What is not mentioned is that they
increased the list price by 80% before putting it on sale. Such a
deal! ;-)

Anyway  to return to the original poster's question, why wouldn't
his PPC partition boot on his mini? The first question which comes to
my mind is if the OS used on his PPC also used the universal binaries.
I assume that if it's anything earlier than the 10.4.4 (Intel) update
to Tiger that there's no way that it could work on an Intel Mac Mini.

Well, if that's the case then you've just explained how Apple was able
to actually "shrink" the size of OS X in Snow Leopard. Getting rid of
the PPC binaries would certainly accomplish that. (Funny I've never
seen this pointed out before.)

While I can't answer the question, I would certainly hope that this
would *NOT* work.

If if did, then that would imply that the program binaries used by
both the PPC & Intel Macs was being stored on your PPC hard drive. IMO
that would be a lot of wasted space! (Lord knows I don't want any OS X
PPC binaries on my Intel MacBook's hard drive.)

No doubt someone else will point you towards a way to migrate the data
for these apps to your mini. But a possible (alternative) brute force
approach that might work for you would be to
(1) clone your existing PPC clone to another disk, partition, or image
to make sure it is saved.
(2) attach the cloned PPC clone to the mini as an external drive
(3) use the install disks that came with mini to do an "Archive and
Install" to the external drive (PPC partition) the tech saved for you.
Choose the install option which will preserve the existing user
settings of the OS X on the external drive.

Hopefully this will result in a migrating the PPC version of OS X to
an Intel flavor which will boot on the mini and with the old settings
and data for you mail, calendar, and address book preserved.
(REMEMBER: Just make sure you don't destroy the original data just in
case something goes wrong).

What flavor of Mac Mini do you have? And what version of OS X is it using?

will a PPC cloned boot drive work as the boot drive for an Intel?

2009-07-28 Thread amorielljason





My dual 2.5 G5 with the CPU error that wouldn't boot (possibly due to bad capacitor acc. to earlier respnses) is still dead.  The local tech cloned its boot drive onto an external hard drive for me so that I could use it to boot our Mac Mini.  He said he wasn't sure if it would work as the boot drive for an Intel Mac.  When I select it as the boot drive, the keyboard won't work when it finally finishes booting.  Does anyone know if an Intel Mac can be booted from a PPC boot drive?  
 
I wouldn't bother; however, the mail, calendar, and address book files don't seem to be readily accessible.  I drag and dropped the files that were indicated in Apple's support pages and other places on the web as the appropriate data files from the clone drive to the Mini, but they still don't seem to come up with the data, so this is plan b. 
 
Thanks.
Jason
