Use snow Leopard from USB

I updated my iMac to maverick.
Unfortunately some old app don't work anymore.
Is that possible to make an USB drive (flash or hdd) bootable with snow Leopard usable on that drive so I can use again my apps?
What is the procedure to do it and use it?
Thanks

Thank You.
I think Fusion could be the best for me. I have that so i only have to add a new virtual machine for SL.
By the way:
Do You know tthe procedure to install and run SL from USB.
I agree with you: it's not practical but economical.
Thank you

Install Mac OS X 10.6 Snow Leopard from USB Drive

My MacBook Pro (Late 2006 15.4-inch 2.33 GHz Intel Core 2 Duo) has a SuperDrive that does not work.
I wish to re-install Mac OS X 10.6 Snow Leopard, as this is the latest DVD I possess, to wipe the HDD prior to selling. It has Lion installed but this was done via the Mac App store and I don't want to sell with any links to my account or as an authorised computer.
How do I boot the MacBook Pro from a USB stick, wipe the HDD and install Snow Leopard?

You will still need a Mac and a optical drive, a external one will do. To read the disk to put it on a USB, external opticals are not bootable.

Start Snow Leopard from USB on a mac mini early 2009

Hi.
It is possible to start Snow Leopard from a USB drive (Pendrive, USB disk, etc)??????
The DVD drive of my mac mini doesn't work properly and I have some problems with my HDD.
Thanks in advance.

Get at least a 16GB USB thumb drive and use this tecnique to make a bootable USB drive:
Borrowed from Kappy,
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your external hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. After formatting is complete quit DU and return to the installer. Install Snow Leopard being sure to select the external drive as the target.
Note that you will need a Snow Leopard DVD. The above will only work for you if you can boot your computer from a Snow Leopard DVD. If you have a new model that came with Lion pre-installed then the above will not work because a Snow Leopard retail DVD cannot boot your model.

Installing Snow Leopard from USB to MacBook

I managed to create a bootable USB pendrive of Snow Leopard from my Retail DVD, and I'd like to re-install it on my MacBook (not using the DVD). The pendrive is not recognized by the Mac at the boot (keeping option pressed), but Finder does. I also tryed to launch the installation process directly from Finder, but it doesn't work.

I just noticed your macbook is running 10.4.11. 10.4 does not support usb booting out of the box. Follow these steps HERE .
How did you clone a 10.6 on your macbook if you are running 10.4?

Can I Install Snow Leopard From USB On Another Mac?

Hello everyone,
I own a 2010 macbook air that came with a snow leopard usb drive.
I've recently been given a 2008 macbook 4,1 that is running leopard. I'd like to install snow leopard on this and use it as a secondary computer. Will I be able to use the usb stick from my macbook air to update this computer from leopard to snow leopard? If updating won't work would I be able to perform a fresh install of snow leopard from my usb drive? Or is my only option to purchase a snow leopard dvd from apple?
Thanks.

Ah! Thank you, Niel. Forgot about the "weird" Air models without any kind of optical drive. I realize to get the Air models as thin as Apple did required the removal of such a drive, but virtually every user who bought one had to then go out and buy an external DVD drive anyway so they could install their other purchased software.

Can't boot Snow Leopard from USB drive made in Yosemite

Hi all,
I have a brand new macbook pro running Yosemite, but some of the software I have will only run in Snow Leopard.
Running Snow Leopard as a Virtual Machine has been clunky, so I wanted to try an alternative and install Snow Leopard onto an external HD and work from that.
I got hold of the Snow Leopard dmg file and created a bootable USB thumb drive (I did this within Yosemite) to try to install it onto the external HD. I used the instructions here:
http://www.maciverse.com/installing-snow-leopard-onto-an-external-hard-drive.htm l
But when I restart the computer and try and boot from the USB drive, I just get the grey background with dark grey apple symbol, indefinitely. The installation process never commences.
What am I not doing right?
Thanks in advance for any insights.

You can only do what you are trying from a model that can be booted into Snow Leopard. You have a 2014 model that can only be booted by Mavericks or Yosemite. You cannot run Snow Leopard on your machine except in a VM or a Mac from 2010 or earlier.

Using snow leopard on external hard drive w/Mountain Lion OS Mac

I need to use Snow Leopard in order to use some expensive software that will not work in Lion or Mountain Lion. All of our computers have been upgraded to Mountain Lion, whcih doesn't support Rosetta. I was able to install Snow Leopard on an external hard drive and it boots up fine from another computer (that is not mine) that has Snow Leopard as its OS.
But when I boot up from my MacBook Pro (running Mountain Lion) and from my Macbook Air (also running Mountain Lion), I can't seem to do it. I hold the "option" key when starting and I get the option to start from the computer's HD or from the external firewire Snow Leopard drive. When I choose the Snow Leopard drive, it crashes and gives me that black screen with the kernel (?) message in several languages that I need to hold down the Power key to turn off the computer and reboot.
How can I get my MacBook Pro or my MacBook Air to boot up from the Snow Leopard external hard drive? (Once again, it DOES work with a Mac that has Snow Leopard as its OS).

You can't if the Mac is a Late 2011 and later, perhaps if it's a Early 2011 (as some came with 10.6 and some with 10.7) and it should be possible for all Intel Mac's earlier than Early 2011.
Also, like what has occurred in the past, Apple does eventually issues a firmware update in later OS X versions so that earlier OS X versions, despite the Mac previously being able to boot from them, won't any longer. However far as I know Apple hasn't done this quite yet, but will one day.
Baring those issues, if you installed 10.6 on a external drive using a machine specific black/gray disk from another Mac, it has hardware drivers for that model/year of Mac only.
If you used the 10.6 white retail disks from Apple, it only has hardware drivers for all previous Intel Mac's that came originally with 10.6.2 or earlier from the factory. Mac's with 10.6.3 or later on the drive from the factory have different hardware drivers, thus not on the 10.6.3 white retail disk.
To find out what OS X version came on your machines, use the free MacTracker and use your model indentifier in the Apple menu More > Info (aka System Profiler)
So for those Mac's that originally came with 10.6.3 or later, machine specific disks must be gotten from Apple, or if your really talented, it's possible to create a univeral 10.6-10.6.8 install disk by combing the 10.6.3 image with the 10.6.8 combo update which will boot on any Intel Mac if the firmware permits and the hardware drivers are compable.
There is a method to bypass the firmware and install on Mac's that are Early 2011/Late 2011 via Target Disk Mode, or via taking the drive out of the machine as some Late 2011's use the same hardware drivers as the Early 2011 machines (only a processor bump basically)
How to revert your Mac to Snow Leopard
For the MacAir, you can install 10.6 via a USB thumb drive, of course provided it has the hardware drivers.
http://www.maciverse.com/install-os-x-snow-leopard-from-usb-flash-drive.html
So in your case you likely should be rather looking at running Snow Leopard in a virtual machine program in Mountain Lion, which MichealLax over at MacRumors has perfected a technique.
Windows in BootCamp or Virtual Machine?

How to revert back to Snow Leopard from Lion?

Foolishly I just jumped straight in, downloaded Lion and installed it, and well... I really don't like it. It's not a patch on SL.
So I'm trying to work out the best way of reverting back to Snow Leopard.
I have:
My Snow Leopard install disc.
A SuperDuper, bootable backup from 48 hours pre-upgrade.
A Time Machine backup from 48 hours pre-upgrade.
I'm fairly sure that just putting the SL install disc in, isn't going to work.
I think I have a couple of options.
1. Erase the hard drive completely, and then do a fresh SL install, then restore the last TM backup.
2. Boot from the SuperDuper backup, then restore the last TM backup.
I'd prefer option 1, as this gives me a clean install (I hope).
Before I go ahead, can anyone:
a) See any problems with carrying this out, or
b) Suggest a better, safer method?
I'm a bit concerned that SL was an upgrade to an existing OS, rather than a complete OS in itself, so I'm very wary of what might happen if I wipe the drive then put the disc in, hoping it'll give me a nice new version of SL. Might need to go and do a bit more reading up.
Thanks.

For ref.
Dragged and dropped copies of important files (Docs, Pictures, Downloads, Movies etc) to a spare drive.
Printed off any docs that I absolutely could not afford to lose.
Shut down Mac.
Attached USB drive with SuperDuper backup, and powered up drive.
Powered up Mac, and immediately pressed the option key.
From the window that popped up, chose my USB drive as the boot disk and pressed return.
Mac powered up running Snow Leopard from USB drive.
Started Disk Utility, and erased the disk labelled 250.06 GB Fujitsu.... etc In the 'name' field, entered 'Macintosh HD'
Started up SuperDuper! and copied my backup over Macintosh HD.
Incidentally, the first step it took was to erase Macintosh HD anyway, so I could probably have skipped the first erase.
Let SuperDuper! do it's thing for 90 mins.
Once it had completed, closed the machine down (it wouldn't let me eject the USB drive, as presumably it was still using that as the boot disc).
Detached and powered off USB drive.
Pressed Mac power button and crossed fingers...
And goodbye annoying Lion, hello again, good old Snow Leopard!
Didn't even need to restore the last Time Machine backup.
I may take another look at Lion again, further down the road, when hopefully Apple will have realised that OS X and iOS are two completely different animals, and that we don't all want our Macs behaving like our iPads.
For now though, I'm sticking with SL.

Boot problem - Snow Leopard on USB flash drive

Built a fresh install of 10.6 on a USB flash drive. The steps I took to do this were:
Installing from 10.6.3 install disc onto an external firewire drive with minimal install option. Drive is hooked into a Mac Pro station
Booted to external drive, installed updates to get to 10.6.8.
Carbon Copy Cloaner the external firewire OS to a 32gb Patriot USB drive
Removed the external drive, then forced the station to boot to the USB drive
The behavior I get is a startup chime, then the grey Apple logo, but NO spinning gear. No other types of signs or symbols come up for roughly 5 minutes. The system then reboots itself and chimes. Then repeat until I hard shutdown and make it boot back to the Mac Pro's internal HDD.
I also tried installing the OS disc directly to the flash drive ( after formatting it ) but it does the same thing. Chime - logo - no gears - reboot.
The drive itself works as I've used it for other purposes and I can see the files on there. The access light is blinking so it appears to be trying to communicate with the computer.
Did I miss a step somewhere?

How do you reinsatll snow leopard from an external optical drive

Both my hard drive and superdrive crapped out. How do i reinstall from an external USB optical drive? I am having a complete brain **** at the moment!

If your replacing your internal hard drive, why not also get the Superdrive replaced?
The OS X install disk supposedly won't boot from a external optical drive, only the internal one.
To OS X onto your new internal drive, your going to need another Mac with optical drive to take 10.6 off the disk and place it onto a bootable USB. Any Mac should do, as the 10.6 installer isn't going to be booted .
http://www.maciverse.com/install-os-x-snow-leopard-from-usb-flash-drive.html
Other methods, requires another compatible Mac.
If you have machine specific 10.6 disks and you have another exact model of Mac, you can use a SATA to USB adapter (or enclosure) to use boot the second Mac with the disk and install 10.6 on the "extenral" drive, then place it back inside the other Mac.
If you have the 10.6.3 white retail so called "upgrade disk" for 10.5 (it also has the full 10.6 on it) and you have another Intel Mac that it's OS X version originally came with anything 10.6.2 or earlier, then it will boot that disk to install on the "external" drive, then it can be placed back into the other Mac.
How to erase and install Snow Leopard 10.6
Another internal drive access method is to use Firewire Target Disk Mode
http://support.apple.com/kb/HT1661
Also one can use a external drive to install the compatible OS X version onto, then option key boot the Mac with the new drive off the external, install Carbon Copy Cloner and clone the extenral to the newly formatted internal drive.

Boot "Lion" of a usb then use it as i would use "Snow leopard"

Hey there, this may sound horribly stupid and amature, so sorry in advance

Then when i turn off the laptop pull out the usb, and boot normally im right back into my familiar home "Snow Leopard" and nothings Changed ??
Cheers in advance, any help/ suggestions are appriciated !

Welcome to Apple Support Communities
If what you want to do is to install OS X Lion (or Mountain Lion) onto a USB drive and install apps there, you can use it. You just need a USB drive with the space for OS X Lion and your apps. Note that OS X takes about 10 GB, so add the size of your applications.
First, you have to format the USB drive by using a GUID partition map and "Mac OS Extended (Journaled)" as "Format" > http://pondini.org/OSX/DU1.html
Then, your USB drive is ready. Now, if you haven't purchased OS X Lion yet, call Apple to purchase it > http://support.apple.com/kb/HE57 They will give you a redeem code you have to insert in the Mac App Store.
When the download finishes, the OS X Lion installer will show up, so follow its steps. In the window where it asks you for the partition to install OS X Lion, choose your USB drive and the installation will start.
By default, your Mac will always start up from the USB drive. As you are going to unplug it, after installing Lion, open System Preferences > Startup Disk, and choose the Snow Leopard disk. Then, when you want to start up from OS X Lion, hold the Option (Alt) key while your Mac is starting, and select your USB drive

How do I delete all my contacts from my IPad 3. I use snow leopard so I can't use icloud. I just got my first IPad so I am new at this.
I believe I can use I tunes. I know how to sync my address book into the IPad but can't remember how to delete the ones that are there.

If you are syncing your iPad with your computer, one way to delete all your contacts might be to connect the iPad to the computer, then in iTunes select the iPad in the sidebar. Once you've done that, go to the Info tab. Uncheck the box for syncing Contacts, then in the lower right, hit Apply. All the Contacts on your iPad will be gone.
You haven't asked for solutions to use Snow Leopard with iCloud, but there are some solutions for Mail, Address Book and Calendar.

How to extract Subtitles from DVD using Snow Leopard?

Hey there,
this may be off-topic, but I don't know where to ask. Anyone know how I can extract Subtitltes and create an .srt File from a Movie DVD using Snow Leopard?

I too have been looking diligently for something I can use to glean .srt files from DVD's. Secondarily, .sub/.idx files. I didn't quite realize how much software would be made useless by my shift to Lion. Amazing amounts!
Is there any other product, commercial or otherwise that is known to accomplish this task?
If one is found, please update the discussion here! Thanks.

Restart with the Mac OS X 10.6 DVD in the drive or with the Lion USB drive connected, hold down the Option key just after the restart, tab to the installation disk, and press Enter. If the computer has a firmware password set, it needs to be provided for this to work.

Can I restore to Snow Leopard from Lion using time machine?

Can I restore to Snow Leopard from Lion using time machine? I did not make a new partition on my external HD. My reason for doing this is to import data from Quicken 2007 to Quicken Essentials and then upgrade back to Lion. Can I restart and hold down the "OPTION" key upon start up that will take me to Apple Recovery HD and recover from time machine? I'm a noob at these sort of things. I appreciate your comments and suggestions.

Probably not. See Kappy's going back to SL from Lion guide.
