Bootable clones for both iMac (Intel) and G5 (PPC) on same external drive??

Is it possible to format and partition one external firewire drive to accept a bootable clone of my iMac (Intel) on one partition and my G5 (PPC) on the other? I seem to remember that in order to be able to boot, the Intel and the PPC require something different in formatting on the drive.
If this is not possible, could I as a second choice format/partition an external firewire drive to place a bootable clone of the G5 on one partition and a Time Machine backup of the iMac on the other? I am looking for a way to store just one rather than two drives in my safety deposit box. Thanks

I put up instructions and a picture showing how to select the partition scheme:

Scroll down to about the middle of the page.
Frankly I was surprised to find out you can boot an Intel machine from a drive that is APM rather than GUID. I'm not sure that what you want to do is going to be as easy as one would hope. Anyway, the instructions I found for dual booting off a firewire drive sounded a bit complex!

  • I have a new iMac 27 and a new Blu Ray external drive.

    I have a new iMac 27 and a new Blu Ray external drive. What is the best way to burn a BluRay disk? I read about TOAST etc but they are getting bad reviews. What software is the best? Im running mountain lion of course. Anyone know of good software to burn this type of disk that ACTUALLY works?

    Okay, a couple of things:
    I still use (mostly) an old version of iMovie because it was/is the only version which will process footage losslessly. However, the newer versions are okay - just do not use the automatic share option, but use  the export to quicktime option where you have many options as to quality, size, etc:
    You will wind up with a .mov file you can drag into Toast to burn (or iDVD to add menus and burn). If in iDVD, you can either burn directly (but not bluray) or make a VIDEO_TS folder which can be dragged into Toast - I also use that if I want to keep a copy to burn later as it has all the necessary files so you can ditch or archive all your clips, etc.

  • Xcode4.0.2 How can i build an application on an a intel machine for both an i386 and a ppc machine

    I can't find the way to change the build settings for both architectures in xcode 4.0.2

    Xcode 4 does not build for PowerPC officially. The following Stack Overflow question provides a hack to build for PowerPC:

  • Can both an intel and a PPC mac use time machine on the same TC?

    I just got a TC and have successfully used time machine with a MBP. I was about to install Leopard on my PPC eMac in order to use time machine on the TC but I wondered if they could both use the TC hard drive as it is currently formatted.
    As I recall, intel macs use journaled GUID and PPC machines use another format.
    Am I deluded?

    I don't think there is a problem, and I believe others have reported in these forums that they're doing it.
    There is a lot of confusion in this area compounded by a number of people who say that some of the Apple KB articles are wrong/misleading.
    But in this case it's more a case of it doesn't matter - here is why.....
    The Time Capsule disk comes formatted, you can erase the disk via the Airport Utility. That's the closest you can come to formatting and you don't have options - so it does whatever it needs to do to get it right.
    The machines being backed up don't access the Time Capsule's disk(s) directly as they do on a locally attached disk. They do it via AFP network disk protocol and the Time Capsule disk is in effect insulated from the machine being backed up.
    (As an aside, it's because of this - the differences in what can be done over AFP - that the Time Capsule stores the backups in a different file format)
    If you add a USB attached drive to the Time Capsule you can also erase it with the Airport Utility as above. In my case, I've attached a USB drive to my Time Capsule. I never had the Time Capsule erase it, but before attaching it I attached it locally and formatted it GUID and HFSJ and it work just fine when attached to the Time Capsule. Does it have to be formatted that way - I don't know - all I know is in this one case what I did works which doesn't prove it has to be that way.

  • Booting Intel Mac and PowerPC Mac from same external drive

    Seems to be difficult. My previous experience and experiments made me conclude you need a separate firewire drive for each variety of Mac. But
    http://rentzsch.com/tidbits/intelbasedMacBootIncompatibility
    does list a method with which this can be done. I hope. Will give it a try. Hopefully this means that down the road this won't really be a question.

  • May I backup both my MacBook & G4 desktop with WD-Passport External drive?

    I want to be able to back up both machines (MacBook and G4) with the same portable drive but not synch them as I have different info on each. Will it recognize each as separate or will it try to overwrite one over the other?
    My tech skills are limited and the Passport was explained as a simple external drive.

    Then you will need to partition the drive unless you want to install Leopard on both computers. To use TM on both computers you will need to install Leopard on the G4. Otherwise you will need a separate partition for the G4.

  • So when I plug my iPhone 3GS into my iMac, for music reasons, it says I have 123 songs. When I plug my iTouch into my iMac it says I have 565 songs on my iTouch. I have the same apple idea for both my iPhone and iTouch, how do I transfer my 565tomyiphone

    When you connect your iPad or iPod to the Mac, click on the device name in iTunes - don't click on the arrow on the device. Then click on the Music tab in the main window pane. Now you should see 'Sync Music' and all your playlists, artists and albums. Here you mark the checkboxes for what should be synced.

    I did the SMC reset for my iMac intel-based and now it won't turn on. What can I do to fix this?

    Well, first things first... is the power cord fully plugged into the back of the iMac (and the wall, for that matter)?
    Make sure the wall outlet has power, too... I've scratched my head over stupid issues where I forgot to flip a wall switch.
    If the outlet does have power, then try doing a pram zap. Command + option + P + R (hold those at startup).
    If the machine is receiving power, you should be able to see some LEDs if you look through the bottom grate of the machine to the left of the RAM door.

  • My Time Machine Strategy for both iMac and MacBook...

    1) Get 1TB external drive, format as HFS+ (including the Gizmodo hint about reformatting Fat32 drives properly by setting GUID Partition table)
    2) Attach external drive to MacBook directly-run Time Machine overnight for initial full backup
    3) Attach external drive to iMac directly-run Time Machine overnight for initial full backup
    4) Attach external drive to my Mac Mini (running Leopard)-don't run Time Machine
    5) Point the iMac and MacBook to the networked drive for future incremental Time Machine backups, by mounting the external drive permanently attached now to the Mac Mini as a shared drive.
    This way, I get the tedious original backup thru direct connection-native Firewire speeds, then rely on the networked wired (iMac) and networked wireless (MacBook) connections for the incremental backups (which, given our usage, isn't that major on an hourly or daily basis)
    Anyone tried something like this successfully?

    If  you have tried the fixes in Pondini's Time Machine Troublshooting, specifically #C12 and nothing helps, then it is time to let one of the genius types at an Apple Store take a look.

  • What is the best external harddrive for my iMac (Intel)

    Out of storage internal hd storage space, would like to run iTunes from an external hd......any recommendations on the best hd for an iMac (Intel)?

    Before you do this, consider backing up requires that you keep at least two copies of your data at all times.  I would consider increasing the capacity of your internal before adding an external hard drive to add to capacity.   See my backup and disk full FAQs*:
    http://www.macmaps.com/backup.html
    http://www.macmaps.com/diskfull.html
    If after reading these you still desire to map to an external drive, you can, and I would recommend drives by http://www.macsales.com/ 
    They do ship to England.
    But remember that means double backing up at separate times for the external drive, and that the external drive may not always be able to daisy chain with a backup drive on the same bus.   That with an iMac frequently might mean having one USB, and one Firewire drive, or using a Time Capsule to backup both internal and external to.

  • What is the best time to set for my iMac intel to get to sleep?

    what is the best time to set for my iMac intel to get to sleep? the default is 10 minutes, i am changing it to 1 houirs but i put the sleep time for my monitod 10 minutes. is it decent?

    Not so sure of that "just plain logic." Allowing  sleep too often will cause wear on the drive -- excessive spin up and spin down. Temperature permitting, a drive will last longer if just left running.
    For other hardware, a lot will have to do with the internal temps. When it's quite hot here, I allow the computer to sleep more often. But otherwise, it's a bit of this and a bit of that. I wouldn't personally recommend running 24/7, although I know of several here who claim they do, with no apparent adverse effects over many years.

  • I have one apple ID for my MAC and another used for both my iPhone and IPad.  Purchases from iTunes don't appear on either my iPhone or iPad only only the MAC. How do I sync the two IDs?

    I have one Apple ID for my MAC and iTunes account and another that is used for both my iTunes and iPad.  When I purchased music from iTunes using the Mac ID, the music isn't available on my iTunes or iPad.  Neither lets me change my ID so how do I fix this issue so I can play the music on all three?

    Hello chlanli
    You would need to use one Apple ID for purchases in order to get them across all of your devices and computer. If you want you can use one Apple ID for purchases and the other one to sync personal data. The article below will explain further.
