Install snow leopard on external HD

I have a 2013 iMac running 10.9.3. I own a snow leopard install disk & I want to install that OS on the external disk but since I'm booted into mavericks it won't let me do the installation. Any way I can do it?

You can't do that on a 2013 Mac; these Macs can't run Snow Leopard except by using Mac OS X Server inside a product such as VirtualBox, Parallels Desktop, or VMware Fusion.

Can't Install Snow Leopard on external drive

Hey Mac Addicts,
I'm trying to install Snow Leopard on an external drive (Lacie Triple Rugged, FW800 USB3.0) but keep on getting "Installation failed, can't copy the support files.
My drive is partioned in to 5x100GB partitions, GUID partition scheme. I boot from my installation disk, choose my partition and hit install. The DVD spins and spins and eventually give me a failure. I've tried not installing the custom options (Quicktime 7, Rosetta and have even unchecked X11) but still get the same.
The MacBook Pro I'm trying this from is running 10.6.8 and previous successful attempts at doing this were from 10.6.4, I'm thinking this is the issue, but would rather not have to clean install my machine and try again.
If anybody has any idea's that'll be marvellous, as I am a little confused and lost, especially as I've done this before.
All the best and thanks in advance.
BigMik

Two things,
1: Use FIrewire
2: Use Disk Utility to first Erase with Security Option Zero All Data, the entire drive, then setup the partitions
3: If it doesn't work, then increase the size of the 10.6 parittion or reducing the partitions until it works.
4: Also do all this from the Disk Utility on the internal drive, then try again from the 10.6 install disk. Apple might have pulled something.
Also you can clone your present OS X 10.6 partition using the donationware Carbon Copy Cloner, however the external partition needs to be large enough for all the contents (recommended)

How to install Snow Leopard onto external hard drive.

I'm currently running on 10.5.8, and I just bought the Snow Leopard installation disc to update to 10.6.3.
My mac has been running on an external hard drive for about a year. The internal just stopped working.
I want to install Snow Leopard onto my external hard drive, but all of my files are on there, and I read that if I do the install, all of the data will be erased.
If I used time machine to back up the files before I do the install, are they at risk of being erased, since they will be back-uped on the external?
This is probably super obvious, but I want to be very careful with this.
Any help is very much appreciated!
^__^

1. The data won't be erased unless a problem occurs.
2. The Time Machine backup should be on a different drive, as drives can fail.

"How to install Snow Leopard from an External Hard Drive"
* Launch Disk Utility
* Select the External Firewire/USB device that you want to use as the boot drive for the upgrade
* Click “Partition” from the menu options
* Select 1 Partition, then click “Options” below the partition scheme
* Select the top option for “GUID Partition Table” – it MUST be GUID to be bootable!
* Click OK to create the GUID partition (this will reformat the drive, ie: all data is lost)
* Next, click the “Restore” tab within Disk Utility
* Select your newly made Snow Leopard 10.6 Install DVD image and restore this image to the GUID partition you just created OR…
* Alternatively, you can select the Snow Leopard Install DVD and restore directly from the DVD to the GUID partition
* After the restoration is complete, your GUID partition will now be bootable by Mac OS X!
* Reboot the Mac holding down the “Option” key to pull up the boot loader, select the Snow Leopard install drive you just created rather than your default Mac OS hard drive
* Install Snow Leopard as usual!
Hope this helps!

Cannot install Snow Leopard onto external drive

I'm attempting to install Snow Leopard on a second drive, an external bare drive in an Icy Dock enclosure connected to a MacPro (running 10.6.6) via serial port. Apple Disc Utility confirms that the external drive (a Seagate 325gb) has a partition map scheme GUID Partition Table. SMART Status is not supported. Connection Bus reads as SCSI but it's connected with a serial cable.
I'm able to perform the first part of the install by selecting the external drive but when I have to restart and complete the install from the original Snow Leopard disc (10.6), the external drive no longer shows up. I've tried several times and have restarted the Icy Dock external drive enclosure.
Any ideas? Thank you.

Not necessarily. Use a backup utility so that you can deselect all the data from within your Home folder as well as third-party applications in order to create a bootable disk but without some of the excess. Any of the following should be suitable:
Backup Software Recommendations
Carbon Copy Cloner
Data Backup
Deja Vu
Silver Keeper
MimMac
Retrospect
Super Flexible File Synchronizer
SuperDuper!
Synchronize Pro! X
Synk Pro
Synk Standard
Tri-Backup
Others may be found at VersionTracker or MacUpdate.
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files.

Install snow leopard on external hdd using windows

My laptop logic board broke. So I wasn't able to erase the hdd. So I took it out put it into my external hdd enclosure. Now I'm stuck on how I would reinstall a fresh copy on the hdd when I only have a windows computer available. I could get a Mac one but that would be a little harder to do, since I have one and I have to go outta my friends. Anyone have a way for me??

Ummm, this is posted in the forum for help with iTunes on Mac.
Fresh copy of what? You're trying to install Snow Leopard on a Windows computer?? Or you are trying to install iTunes on a Snow Leopard drive in an external enclosure to run on a Windows computer? Need some clarity here please.

Install Snow Leopard on External FW Drive

Snow Leopard will only install on a GUID partition. I usually have two or three separate volumes on my external drive. If I partition my drive prior to Snow Leopard installation, the scheme is Apple partition map and I cannot install Snow Leopard on any volume. So I assume in order to do an install of Leopard, I must install to a single GUID partition because it seems there is no option to make any of the volumes a GUID partition. Am I correct? On this particular drive, I wanted to have a bootable clone
of my MacBook Pro HD, a bootable disk image of my Snow Leopard Install Disk, and a third scratch volume for temporary video storage. What would be my strategy be to accomplish this?

no you can have any number of volumes on a GUID partitioned drive.
select the whole drive (model, not name) in disk utility. click on the partition tab. set the number of partitions to 3 (or whatever), click on options and select GUID. set the formats for each partition, adjust the relative sizes and hit "apply".

this will work just fine once you reformat the drive as above.

Installing Snow Leopard on external HD for games?

Hi, I just bought a new Macbook Pro running Mountain Lion, and I have some old games (like Neverwinter Nights) that used Rosetta and won't run on this machine. I'm wondering if I could install Snow Leopard on an external hard drive, boot up my Macbook from it, and run the games that way. Would it work and how would the perfornance be, seeing as it's running from an external?

No sorry, 10.6 doesn't have the hardware drivers for your newer hardware.
However there is a unsuported hack to get 10.6 running in Parallels virtual machine software, but you will lose performance naturally.

I want to save important files/programs on an external hard drive, delete EVERYTHING on my computer, install snow leopard, and reload everything i saved on to a clean slate. Is this possible/practical?

I was just thinking that it would be better to wipe the entire hard drive clean and reinstall some programs rather than go through and move certain things to the trash. Basically rebuild my software and file collection from the ground up, omitting what is unnecessary. Then again, I have no idea what i'm doing.
My macbook was purchased in late 2008. 2gb RAM. OS X 10.5.6. It's been going very slow lately so i decided i would look up how to improve. Snow leopard was recommended as well as changing my RAM. And so here I am.
I don't have an external hard drive so i was going to just compress all my files and save them to my emac via ethernet. would they be harmed?
also, i have alot of projects in ableton (a music recording/writing program). Would saving and transferring them be just as simple as finding the song? or are other components of a certain song saved in other locations?
sorry this is so lengthy. i should probably stick with something simple but i just want things to run as smoothly as possible for as long as possible
thanks very much

Here's some info that may be helpful.
Installing Snow Leopard: What you need to know
http://www.macworld.com/article/1142454/install_snow_leopard.html.
You should get a Firewire connected hard drive and backup your MB's HD to it. That way, if something goes wrong during the installation, you can recover your current sytem, apps and files. After the SL install, you can use the external HD for frequent backups.

I have a 2007 Macbook Pro that is running 10.7.5 and I am trying to use a 10.6.3 DVD to install Snow Leopard to an external hard drive.

I have a 2007 Macbook Pro that is running 10.7.5 and I am trying to use a 10.6.3 DVD to install Snow Leopard to an external hard drive. I've followed every possible instruction on every which website. The problem is when I boot to Install disc, I am unable to choose which hard drive I'd like to install the OS on. It says that it is unable to Install and automatically takes me to Restore and suggests that I restore to Time Machine backups. Any and all help is appreciated.

lovinlife5959,
have you tried booting from the grey Mac OS X Install DVD that originally came in the box with your MacBook Pro? See if you can install its version of Mac OS X (either 10.4.9, 10.4.10, or 10.5.0, depending upon when it shipped from the factory) onto your external hard drive. If that works, boot from your external hard drive, run Software Update on it, and then try updating your external drive to 10.6.3 via the white Snow Leopard DVD.

Hi.
You simply can't. Snow Leopard is compiled in Intel binary only.
Good Luck.

You cannot. From a legal standpoint, the license agreement for OS X mandates that you run OS X only on Apple hardware. HP is not (yet) owned by Apple.
From a technical standpoint, your HP laptop doesn't use EFI, but rather an early predecessor called a BIOS. Apple is the only vendor of consumer computer hardware that uses EFI; other vendors reserve EFI for use in servers.
Secondly, Apple's operating systems support a rather limited number of configurations of video hardware and mainboard chipsets directly since they need only support those systems that they manufacture. You cannot use Windows software or drivers on OS X, so prior to installation, you would need to write your own hardware drivers for your laptop, create an OS X drive image on a Mac, and then modify that image with your drivers before putting it in the HP.
It will be simpler (and legal), to simply purchase a used Mac. Apple's online store has refurbished MacBook Airs starting at $850 and Mac Minis for $700. If you go to e-bay or craigslist, you'll find used Macs for considerably less.

Can I install snow leopard on an external hard drive so I can run quicken 2006, and put snow leopard on my imac harddrive

Can I install snow leopard on an external hard drive in order to run my quicken 2006, and install lion on the hard drive of my imac?

You don't need to erase the drive and repartition from scratch. You may be able to add a second partition on the fly. The caveat here is that once you do that you cannot create a Windows partition using Boot Camp. Of course if you have no plans for Boot Camp then it isn't relevant.
To create a second partition on your existing startup volume:
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.
Now, you cannot add a new partition that exceeds the amount of contiguous free space at the end of the drive. Disk Utility will fail to add the partition if it cannot find sufficient contiguous free space. If that's the case then you will need to follow your state outline - backup, boot from clone, erase internal, repartition internal, restore backup to one of the partitions (or both in your case.)
