Can I have Leopard and Tiger on different drives???

The whole question: Can I have Tiger on one drive, Leopard on the other, and run the same programs from whichever one is the boot drive?
Will having the other OS on a nearby drive get in the way of anything? Both internal drives have Tiger on them, so If one goes nuts, the other might be helpful, but can that second drive become Leopard, so I can boot it and poke about? Will the Leopard drive be able to run the programs that are currently working within Tiger?
Is this asking too much?

I'm not sure I understand you question
Yes you can run Leopard on one drive and TIger on another - I currently have leopard on an external drive and Tiger on my internal drive
At David DeCristof's suggestion I cloned TIger onto the external drive (using Carbon Copy Cloner -- CCC) and upgraded to Leopard there
Since both drives contain all the same data and applications (at least started that way) I can run anything on either -- if I save data from Tiger that I want to keep after I clone Leopard back to my internal drive I will have to be careful to stove it on the external drive
It is, IMHO, a smart way to upgrade

  • Leopard and Tiger on Separate Drives: questions. Many externals. Graphics

    Hi,
    I have multiple Macs, most networked, and have installed Leopard on all but my "graphics" computer. I use this one for my photography, and am just gathering my nerve to move. I am wondering whether to wait, to install Leopard on a separate internal drive, or to upgrade.
    My system: Mac Pro Quad (16 Gigs max, and I have 16 gigs). 4 internal 750Gig drives. Sonnet Tech. PCI-e port multiplier SATA card (4 external plugs: 2 connected to 5 drive bays). Epson 4800 printer using ColorByte Software ImagePrint 7. Other key apps, CS3, Lightroom, Aperture. Misc. usb and firewire drives and devices including WACOM. My photo libraries, are all on the external SATA drives, and backed up to other external SATA drives. I use Chronosync for the backup. We are talking almost a Terrabyte, so I wasn't planning to use Time Machine.
    Advice? Should I install leopard on a separate internal drive, but leave Tiger? Can I use data files from other drives with either operating system without screwing up my files. Can I use application files located on the Tiger boot drive, from Leopard?
    So, alternate boot drives?
    Is anyone aware of Leopard issues with any aspect of my system, as described?
    If I go with leopard, do I start from scratch and reinstall everything (which is a total pain considering the number of serial numbers, and upgrades, involved?
    Anything I should have asked but didn't? Thanks for the help

    Keep Tiger. Install Leopard on a separate volume, using the Erase & Install option, followed by migrating from the Tiger volume, because there have been problems, especially with ownership and permissions. See these for details:

    That allows immediate recovery into a known, good state.

  • I want to triple boot Have Snow Leopard and XP on separate drives and I want Windows 7 on another drive, can it be done by temporarily removing the xp drive and installing windows 7 on another internal drive?

    I want to triple boot my Mac Pro I have Snow Leopard and XP on separate drives (osx on drive 1, xp on drive 2) and I want Windows 7 on another drive (drive 4, drive 3 is used by osx for storage), can it be done by temporarily removing the xp drive and installing windows 7 on drive 4?
    I realise bootcamp only allows 2 operating systems and refit could change the size of my current xp drive to accomodate W7, that is not an option here for various reasons one being the drive is pretty much at capacity with only about 30gig free (I work with video so that free space fluctautes quite a bit). I have a brand new drive 4 with 1TB set aside ready for W7 but I'm unsure how to go ahead?
    any help or advice would be really appreciated, thanks

    Boot Camp is used to support Windows on the same drive.
    You can have a different OS on every drive.
    You could have Windows 7, Vista, and XP all on one drive if you so choose.
    I recommend not putting Windows and OS X on the same dirve when talking about Mac Pro - unless you just need something small and lite.
    Remove all your other drives while you install Windows 7.
    You could even relocate XP - if you need it even - or recover the hard drive space.
    You should always keep 30% free for Mac OS; same for data/media drives.
    Considering 1.5TB WD Black $110.... and you want OS X to be on a fast high performance drive as well.

  • I currently have Leopard, and there are no longer updates for it. So I must upgrade to either Snow Leopard or Mountain Lion. Without doing so I cannot update my itunes, and my ipod is no longer compatile with my mac. How can I buy the upgrade

    I currently have Leopard, and there are no longer updates for it. So I must upgrade to either Snow Leopard or Mountain Lion. Without doing so I cannot update my itunes, and my ipod is no longer compatile with my mac. How can I buy the upgrade, since I do not have access to the mac store as that comes with Snow Leopard? I went to Best Buy and they said neither Snow Leopard or Mountain Lion can be bought there.

    Start by checking if you can run Snow Leopard:

    http://support.apple.com/kb/SP575
    Whilst Apple have withdrawn Snow Leopard from their stores, you can still get it from Apple by calling 1-800-MY-APPLE (if you are in the USA) and they will supply the SL DVD for $20 for a single user, or $30 for a family pack that covers up to 5 Macs.  You can also purchase the code to use to download Lion from the same number (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:

    If you are outside the US call your national Apple Helpline:
    http://support.apple.com/kb/HE57
    If you're in the UK, use this number: 0871 508 4400
    When you have installed it, run Software Update to download and install the latest updates for Snow Leopard.
    To use iCloud you have to upgrade all the way to Mountain Lion:

  • Can I have primary and standby in same OS but different releases.

    All,
    Can I have primary and standby DBs in same OS but in different releases?
    i.e. primary is in RHEL 5 and standby is in RHEL 4, is it ok to setup or do we see any issues?
    Thanks,
    Mahi

    In 10g, dataguard started to support different binaries on primary and standby database servers with the same OS family. For example Microsoft Windows 64-bit on primary and Microsoft Windows 32-bit or Microsoft Windows 64-bit for AMD on standby database server. However with 11g, dataguard also supports different OS on primary and standby servers

  • How do I partition my MacBook Pro so I can keep Snow Leopard and also install Mountain Lion?

    How do I partition my MacBook Pro so I can keep Snow Leopard and also install Mountain Lion?
    I want to install the latest OS, but I already know that I will lose a lot of my software unless I can partition the hard drive and have two "bootable" drives.
    How do I retain everything I have, partition the drive, then reloa the software I own according to which OS it will work under?

    I do not currently own OS X ML.
    I am currently running OS X (10.6.8 Snow Leopard) on my MacBook Pro. It has a 2.8GHz Intel Core 2 Duo Processor. I want to upgrade to Mountain Lion, but many of my software titles will not operate with ML and I cannot afford to replace some of them (Adobe Creative Suite, for e.g.)
    After I back-up my HD and then partition the HD, how do I use the back-up to reinstall what I want to the SL partition, and then place the rest on the ML partition.
    I have not done what you want to do, so can only offer some general thoughts in support. Take value from the following where you can. No guarantees.
    If it was me, I would use a disk clone utility (e.g. Carbon Copy Cloner) to image the existing Snow Leopard disk to an external drive. Then verify that the external drive would boot and run Snow Leopard normally.
    I would then purchase and download the Mountain Lion upgrade installer, but not run it. Use Lion Diskmaker to make a bootable USB stick, and perform a clean install of Mountain Lion, replacing the Snow Leopard on your MBP. This way, you make absolutely certain that no third-party drivers or other SL cruft remains to make Mountain Lion unstable. Update to latest ML point release. Fix permissions. Let TimeMachine make a full backup of your ML installation to a different external drive. Then turn of Time Machine.
    In Disk Utility, use the + sign at the bottom of the ML partition to add another GUID, HFS+ Journaled partition for Snow Leopard. Resize to taste. Name it differently from your ML partition. Exhale.
    Now ideally, you would like to reverse the external clone and put it back into the new SL partition. Then fix permissions. And demonstrate that you can boot into individually stable OS X installations. This would save you alot of work. Resist copying your home directory into ML just yet.
    If you cannot successfully achieve the preceding paragraph, you will be faced with a full SL and application reinstall.
    The ~/Library contents for SL and ML are sufficiently different that you do not want to mix them. You may want to salvage Safari bookmarks.plist. And, ML created folders in the home directory may have different permissions or ACL settings than in SL. So, my rule of thumb would be to copy folders that you created in SL, and only the contents of matching named OS created folders such as Music, Pictures, Downloads, etc.
    For each operating system, you probably want the Time Machine settings to exclude the opposite OS X partition. If you use the same host name in Sharing prefs, then you will mix SL and ML backups on the same Time Machine back up drive. If you use different host names, they will be distinct folders in the Time Machine backups.backupdb and allow discrete restores per host. You may also want to gag Spotlight from indexing the opposite OS X partition.

  • MacPro with both Leopard and Tiger drives. Want to switch iTunes How

    I am running a MacPro with both Leopard and Tiger drives. I finally want to switch everything to Leopard and its drive. I have iTunes on the leopard drive but have never used it. How can I transfer my iTunes music, iPhone Apps etc. from the Tiger iTunes to the Leopard with the least amount of fuss?

    Hello hassiman,
    For additional information regarding moving the entire library from the 10.4 partition to the 10.5 partition, see this article:

    If your iTunes Library is substantial, you may want to consider backing it up to an external location as well:

  • Is it possible to have Leopard and Snow Leopard at the same time?

    If you have an Imac with an external USB HD, can you have Leopard on the HD of the iMac and install a fresh copy of SL on the HD? Would it work?

    Thanks for asking, you reminded me of two things to keep in mind. Let's say you have two drives, let's call them SL and Leo. If you boot with SL all your preferences and settings are on the SL drive and if you boot with Leo, they are on your Leo drive. There's no crossover and nothing dangerous to worry about.
    There are, however, two little things to think about. a) by default, when you boot with Leo your files will save to your Leo account folder and when you boot with SL they'll default to your SL account folder. This can get confusing. There are several solutions but the easy one, and the one I used, is to use DefaultFolder and set default save folders so that the file selector automatically chose my SL folder to save into.
    The other issue involves Spotlight. When you switch from one OS to the other, Spotlight will try to reindex both drives. This isn't dangerous but it does bog down a slower computer. My solution was to use the Spotlight preference in Leopard and turn indexing off completely by making both drives private.

  • Installing Leopard and Tiger on the same computer ...

    Hi,
    How could I install both system, Leopard and Tiger, on my iMac G5 giving me the possibility to startup from one of them at a time ...
    I want this to have this possibility to run occasionally classic (with Tiger) while using mainly Leopard. Is this possible ? What are the drawbacks of this possibility ?
    Thanks in advance.

    Thanks for your feedback ...
    Smokerz's comment was not clear to me. I thought he meant that having 2 «Applications» folders is «complicating» things. I am french canadian and sometimes english way of speaking is not fully understood. That is why I asked for a confirmation.
    I thought that since all partitions would be available, that with 1 «Applications» folder, apps could be used in both world. If I have 2 versions of MS Word, witch one will open when double clicking on a Word document. I think that what we have to keep in mind is that apps have to be Tiger «and» Leopard compatible. Maybe I misunderstand, but that is what I see as the potential problem.
    If what Smokerz meant is to have 2 independent systems, it is not what I was looking for when beginning this thread. I have been using OS 9 and OS x with the advantage of switching from one environment to the other and loved that possibility. I thought that I could have an environment where all my documents could be available when working either in Tiger or Leopard. If I desired to have OS 9 for my accounting package, I would startup my Imac with Tiger and Classic. Once finished, I would reboot with Leopard.
    I know that there is an emulator called «SheepSaver» to run OS 9 on Intel machine, but have not been to confirm the speed of that solution. Maybe it is also possible to run it on PPC machines ... I will look into this possibility.
    Thanks for helping.

  • Can I have two iPads with two different credit cards linked to one iTunes account?

    Can I have two iPads with two different credit cards linked to one iTunes account?

    It is still not possible to have two credit cards with your iTunes store account. I've just had a discussion with an Apple representative who suggested I give feedback to Apple about this. The more we are, Apple might listen to us in the end.
    This is the link
    http://www.apple.com/feedback/itunesapp.html
    Please feel free to use or modify what I wrote there:
    I’m surprised as are many other people who have the same issue (can see this in many forum threads) that Apple don’t give us the possibility to have at least 2 credit cards with one AppleID/account like most other vendors do (even much smaller than Apple). This certainly forces people to buy some stuff elsewhere that they otherwise would have purchased from Apple (for example books) or restrain from buying things they would have bought if they had a choice to use a second Credit Card.
    Not having this option puts me in a precarious situation since it would not be OK to buy just anything with the Credit Card that is tied to my business (and in many cases like mine the business is only one person, the VAT No being the same as my social security No).
    Sole traders need an option too.
