Can I dual boot lion and OS-10.5.8?

I want to use my mac pro with Lion for it's iCloud feature and iPad2, but also be able to use some old programs on the MP in 10.5.8.  Can I have both OS on the Mac ?

Yes. You have to partition the hard drive into two volumes. One volume will be for Lion and the other will be for Snow Leopard. You can resize your current partition scheme:
To resize the drive do the following:
1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.
2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss.  Your drive must have sufficient contiguous free space for this process to work.

  • [SOS]Which mac mini device can install dual boot(Lion and Mt Lion)?

    Salutations!
    Due to my assignment, I need to get mac mini device which support dual boot.
    Which mac mini device model/firmware can we install dual boot(Lion and Mt Lion) on it?
    I got late 2012 one, but it looks like it does not support.
    Please help me.
    Thank you so much,
    TriQuang

    Hi Niel,
    Thank you for your fast reply. So if I buy mac mini MC815 model, which comes with preinstalled Lion I can run dual boot(Lion and Mt Lion)?
    I have one more question: Can I install Mac OS 10.6 on that mini device? If it's not supported which mac mini model can I get to support Snow Leopard and Lion and Mt Lion?
    Thanks and best regards,

  • Can you dual boot lion with an older verion of Mac OS?

    Can you dual boot Lion Os with and Older version of Mac Os (Snow Leopard?) So one can rum Power PC apps until they are upgraded?

    You can dual boot if your machine originally came with an older OS version. No Mac can boot from an older version than the one it came with - notable exceptions are if the machine was built right around the time of the new OS release; in that case, it would depend on the machine and OS builds - it may or may not be possible.
    So the important question here is: did yours come with Lion preinstalled? The answer is most likely: No. Or Snow Leopard? The answer would be: Yes.

  • Dual boot - (Lion and SL) Wifi in SL none in Lion - very disappointed in Apple

    I installed a SSD drive in my 15.4 mid-2009 Macbook Pro to be able to daul boot into either Lion or Snow Leopard.  I did this because the first time I tried to upgrade to Lion I had no WiFi hardware but after going to Apple we figured it may have been something during the update so we rolled back to SL.  I also found out that my optical drive died at the same time - kinda wierd.  So I put the SSD in where the optical drive had been and installed Lion 10.7.2.  Booted up and no WiFi Hardware installed again.  So I booted back up into SL and no problems at all with WiFi.  So I took my laptop into the Apple store expecting the usaul Apple care where they would take care of this problem even though I was out of warranty.  Showed the genuis guy the problem. 
    Well they ended up charging me to put in a new WiFi card and told me I was getting a bonus because they replaced the screen - even though when I dropped it off the only problem with the screen was a dent on the outside.  So they sent me off charging me $68 for the new card and losing future business from way more than the $68 they got from me.  As an IT manager I'm responsible for 15 macs - that will now all be on SL for a long time.  I will also be much slower to update the 10 iPhones to the latest versions.
    Thank you apple for sending me away as an unhappy customer - not liking the new apple.  The old Apple would have just taken care of this issue without a question.

    Many apps are "self-contained" and so can run from any partition.  So you could just move the apps to one location so that you can run and update them from either.  (As long as the apps did NOT have to be "installed".)
    So you partitioned your one internal hard drive?  You could also install OSX to an external hard drive.  Then turn of that hard drive when not booted to it.
    Is there some old apps you need, which is why you must still use SL?  If so, SL that is what I would put on the external hard drive.  Since it is apps you wouldn't be able to update anyway, putting SL on the external drive just for the things that can't run in Lion makes sense, since you can turn it off when not needed.  Otherwise, if you're holding on to SL "just in case", then eventually I suggest to take the leap and move completely over to Lion when you're ready, which obviously removes the need to dual boot.
    (I realize you have a Macbook Pro, so an external HD is not ideal.  But there are many physically small HDs that aren't too inconvinient, especially if you get a Firewire bus powered drive.  And you have a 17" MBP so I'm assuming size and weight aren't an absolute, top-most, high-ranking priority. )

  • What new MacbookPros will support dual booting Lion and Snow Leopard?

    I was looking at http://www.macmall.com/n/macNavLinks-305?q=8899071
    I need a system that can dual boot so that we can use older software that isn't supported by Lion.

  • Make dual boot Lion and Snow Leopard Mac ???

    I have a SSD for my MBP. I formatted it with two partitions and installed snow leopard on each. I also have a 400 GB HDD that has snow leopard on it. I'd like to trade out my optical drive for the SSD. I'd like to update one SSD partition to Lion, then use the software and data files from the HDD for both snow leopard and Lion. That way I hope to still use the snow leopard software that is not compatible with Lion (I still have some legacy PPC programs) and have the benefit of new Lion only software.
    Can I do this? If so what do I have to do? Any resources with HOW-TO for this sort of thing??
    2009 MBP with 10.6.8

    Do you have any tips for making your home folder stay on the HDD and still get the files I need on each SDD partition?
    I assume you are talking about application-specific data like preferences.  Most stuff is kept in your home dir.  You really have to know which apps are exceptions that put stuff in /Library and other boot disk related places (e.g., kexts).  I always keep careful records of what goes where from anything I add to my system so I know how to handle this.  Generally though I suppose Migration Assistant helps most users (I never used it).
    One scheme you might do is simply ignore the problems until they occur on a app-by-app-basis.  If you run from one of the boots and something you use needs a kext or registration because its not on your common home dir, then install as needed or reregister as needed.  Preferences can easily be respecified (or dragged from a backup if you know what to look for and where).
    Most of your stuff in your home dir will run as it did before if the stuff doesn't use any boot directories.  But as I said in my first post there is that risk that some apple-specific data bases might have changed going from Snow Leopard to Lion like those Mail and Address Book examples.  No way of know that until you try.  Hence the emphasis on backups.
    If there are some user-specific data that has changed between Snow Leopard and Lion (say, it's Mail or Address Book) then this whole common-home-for-both-snow-leopard-and-lion scheme needs to be rethought.   As I said earlier, it has always worked within a single OS family and I don't recall even having any problems up to Snow Leopard.  But the jury is still out on Snow Leopard to Lion.
    With respect to applications you want to put on the SSD, that's your choice.  What do you use the most and launch most often?  Put them on your SSD if you wish.    Thinking out loud -- maybe consider a relatively small third partition for these apps on the SSD.  It would appear as just another mounted volume on your desktop and then you would have only a single instance of those apps for both boots.  Most apps don't need to be in /Applications.  Those that do of course would have to have two instances, one for each boot.

  • Can I dual boot Mavericks and Snow Leopard?

    Hello. I own a 2011 i5 iMac. I recently started working with some softwares that will only work properly on Snow Leopard, but I have Mavericks installed. My question is: can I create a new partition in my HD and use BootCamp to install Snow Leopard?

    If it is a Late 2011 model, then you cannot. The earlier models came with a special version of Snow Leopard on DVDs. You can install only that version of Snow Leopard. If you've lost those discs, then you are out of luck.
    You do not use Boot Camp for this. Rather, you will use Disk Utility.
    To resize the drive do the following:
    1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
    2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
    3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)
    4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
    You should now have a new volume on the drive.

  • Dual boot Lion and Snow Leopard?

    I have a first generation MacBook Pro unibody, and recently installed Lion on it.  I had been using Snow Leopard since it came out, and it works beautifully.  I had no idea (should have done my homework) that several of my programs would cease to function.  I have a Nikon Super Coolscan 4000 ED that I need Nikon Scan 4.2 to run, as well as Photoshop CS2 that I use to edit my images from the scanner.  I don't really want to pay for Silverfast as it is over $400 and see no need when Nikon Scan works beautifully.  I am planning set up a second partition on my hardrive and installing Snow Leopard on it to run those two programs.  My questions are this:
    How much space should my second partition be?
    Can I access the image files on Lion from the Snow Leopard partition?
    Thanks,
    Jared

    IMHO the Nikon software requires Rosetta and Lion doesn't have it. So you can't use it with Lion.
    Since I have PS CS3, I don't know about PS CS2 but I suspect it is also in the same boat.
    If you set up a Snow Leopard partition, my suggestion would be to make it at least 40 GB larger then your current photo library.

  • I currently run Mac Pro with three hard drives. Can I dual boot or even triple boot with Snow Leaopard on one drive and Mountain Lion or Lion on others?

    I currently run Mac Pro with three hard drives. Can I dual boot or even triple boot with Snow Leopard on one drive and Mountain Lion or Lion on others?
    I need to keep Snow Leopard so that I can run some old softward.

    If you are careful you can put at least two on one drive, having Recovery from Lion and Mountain Lion on their own drives though.
    CCC can clone Lion Recovery - great for moving or backup.

  • Can I dual boot snow leopard and mountain lion if I've installed boot camp on my drive

    Can I dual boot snow leopard and mountain lion if I've installed boot camp on my drive

    Yes as I said before. If your model Mac came with Snow Leopard and you are now running Mt Lion and have Windows installed in a Boot Camp Partition all you have to do is make the Mt Lion partition smaller, take the free space and make it another Mac partition and you should be able to install Snow Leopard into that partition.
    I have Snow Leopard, Lion and Mt Lion installed on my MBP. No Windows in a Boot Camp partition because I run Windows XP in a Virtual Machine on both Lion and Mt Lion.

  • Can I dual boot Mountain Lion and OSX10.6.8

    Can I dual boot Mountain Lion and OSX 10.6.8. I just upgraded to Mountain Lion and my InDesign CS2 no longer works. If yes, how does one do it.
    Thanks all,

    Yes, as long as your computer shipped with 10.6.8 or earlier. Insert the Mac OS X 10.6 DVD, restart with the C key held down, and install it onto a separate partition or drive; if you use Boot Camp, repartitioning the internal drive may disable it.

  • Can I purchase Mountain Lion and make a flash drive bootable? I do not want to install it on my Macbook Pro. I have Snow Leopard on my Macbook Pro now, and due to my hard drive needing repair I need to boot off of another source, like my flash drive.

    Can I purchase Mountain Lion and make a flash drive bootable? I do not want to install it on my Macbook Pro. I have Snow Leopard on my Macbook Pro now, and due to my hard drive needing repair, I need to boot off of another source, like my flash drive. I am in Paris and my Snow Leopard DVD is in Texas.

    Mac OS X has a built-in disk diagnostic and repair program called fsck or file system consistency check. Here’s how to verify and repair your startup disk with fsck.  As soon as you hear the startup tone, press and hold Command-S on the keyboard. Keep holding down those keys until you see a black screen with white lettering. This is called “booting into Single User Mode.”  As the Mac boots in this mode, the screen reports each step of the process. The line should end in root#.  Right after the root# prompt, enter the following: /sbin/fsck -fy
    If repairing the disk in single user mode fails, it means one of two things. Either your hard drive itself is failing (a hardware failure), or the directory damage on your hard drive is beyond the capability of the built-in repair procedures in OS X.

  • Can I dual boot OS 9 and 10.5 on one of these (G4 MDD)?

    Simple question, can you dual boot OS 9 along side OS X Leopard on I'm looking a 1.25ghz G4 (single processor), basically the last one Apple ever released in 2003. It says in the specs for it that it can boot OS 9.2.2 and it is also compatible with Leopard. I know Leopard isn't compatible with the classic environment but I don't want classic in OS X, I merely want to be able to boot into OS 9 for some games, and when I want to use the web to be able to boot into Leopard.

    Welcome!
    Does anyone know of a good and trusted source for the original install discs for this machine?
    Several people here have called Apple fpr these and were told they no longer carry replacement disks for this machine. It's back to eBay or the local Mac user group. Any used Mac that does not come with the system restore disks should be considered defective and avoided, or at least heavily discounted. Can the seller find the disks for you?
    Every time I try to transfer a System Folder to the machine..........
    That because you need the special version of OS9 on the system disk.
    I do have a 733 G4 with a valid OS 9 System Folder. Can I transfer that via target mode and expect it to boot the 1.25?
    I've not tried it but, based on my experiences with my MDD and its special needs, I don't think that will work.
    If you get a righteous system restore disk set, there is one more hoop: OS9 will not boot if installed on a volume larger than about 195G. I tried installing it on a 250GB drive. It installed and would work in Classic emulation, but would not boot until I wiped that drive and made a modest partition in which OS9 resides.

  • Can I dual boot with MAC OS/X and Windows

    What is the best way to configure a dual boot on my MAC Bookpro laptop? Also, can I dual boot Windows 8 and MAC OS?

    The first alternative is a dual-boot arrangement between OS X and Windows provided with OS X.
    Windows on Intel Macs
    There are presently several alternatives for running Windows on Intel Macs.
         1. Install the Apple Boot Camp software.  Purchase Windows
             XP w/Service Pak2, Vista, or Windows 7.  For Boot Camp
             4.0 and above you can only use Windows 7 or later. Follow
             instructions in the Boot Camp documentation on
             installation of Boot Camp, creating Driver CD, and
             installing Windows.  Boot Camp enables you to boot the
             computer into OS X or Windows.
         2. Parallels Desktop for Mac and Windows XP, Vista Business,
             Vista Ultimate, or Windows 7.  Parallels is software
             virtualization that enables running Windows concurrently
             with OS X.
         3. VM Fusion and Windows XP, Vista Business, Vista Ultimate,
             or Windows 7.  VM Fusion is software virtualization that
             enables running Windows concurrently with OS X.
         4. CrossOver which enables running many Windows
             applications without having to install Windows.  The
             Windows applications can run concurrently with OS X.
         5. VirtualBox is an Open Source freeware virtual machine such
             as VM Fusion and Parallels that was developed by Solaris.
             It is not as fully developed for the Mac as Parallels and VM
             Fusion.
    Note that VirtualBox, Parallels, and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc.  There are performance differences between dual-boot systems and virtualization.  The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech Labs- Virtualization Benchmarks, January 2013 | MacTech for comparisons of Boot Camp, Parallels, and VM Fusion. Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
    You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

  • Dual boot Windows and Linux?

    I recently bought a T61, and will be taking a programming course.  One prof I spoke with said they ask us to use Unix tools, so one option is to dual boot linux and Windows.  I haven't decided yet whether I will keep Windows Ultimate, or go to XP for this.  But I was wondering how easy/hard is it to make this work, and what kind of steps need to be taken?   If you could point me towards any good tutorials/guides that would be appreciated too.
    Also, I have never really used linux, so which version is best?  I will be needing it for programming, but also still want to do the basics like web surfing, music, dvd's, burning discs, etc.  I have an old copy of Ubuntu that I never used, but its probably about 4 years old.  Is this still acceptable or will I need something newer?

    Hi,
    If it's just a couple of programming courses that you are going to take I suggest you'd try out VMware player:
    http://www.vmware.com/products/player/
    You can get this software for free and since your system packs a lot of punch it will be able to run it smoothly without any hassle. I'm an engineering grad student and I have to do alot of programming. I've used VMware player before to do some software developement in Ubuntu when I didn't have enough HD to install dual boot but still couldn't do all my other stuff without XP.
    VMware Ubuntu will need a bit of fiddling to get it work just right (USB devices, etc) but it shouldn't be harder than installing a dual boot (actually it is alot easier for my opinion). The only down side is that file sharing between VMware and Windows can be somewhat difficult. I used an external USB drive to share my files but you could always set up Samba to handle file sharing.
    I hope this helps out with your decision.
