Testing Leopard on External Drive/Keeping Tiger on Internal-Any Problems?

I am currently running Tiger 10.4.11 on my internal HD and I want to install Leopard on an external drive to test it against my applications before I commit to making the switch.
Are there any problems, concerns and/or precautions I need to be aware of or take when installing Leopard to the external drive? I have SuperDuper which has cloned my Tiger drive.
Once I've installed Leopard is there anything I should be aware of when booting Leopard off of the external drive and running my applications on the data that is on my internal HD?
Thanks

No real issues. Just be sure your external HDD is partitioned with a GUID scheme, not Apple Partition Map (check that in Disk Utility).
Hope this helps...

Installing Leopard on external drive / then making it internal

Hi There-
Please tell me if you think this scenario will work. I'm running out of room on my mac mini's hard drive, so I bought a new drive along with Leopard. I want to install leopard on the new drive in an external firewire cage and set everything up. Then when I'm satisfied, I can crack the mini open, pull out the internal drive with a working tiger install, put the external drive in (with leopard) and just let it boot.
Is it that easy?

Yes that will work.

Ever since snow leopard my external drive keeps disconnecting

i love airport base station extreme- it worked well for years. i get snow leopard (which is also great), but- now my external keeps disconnecting. i have it partitioned for time machine as well. but now it keeps disconnecting after five or six minutes. any help?

I am experiencing the same issue. I lost a complete hard drive volume due to this situation. About 2 years of data down the tubes and unrecoverable through Drive Mechanic 3 and other sources.
Please Apple, look into this as I am about ready to downgrade back to Leopard to prevent this. I thought it was my firewire enclosure but it turns out it is doing it with my USB mounted drives as well.
Both drives have been plugged in to external power by the wall plug and not bus powered so that would not be a cause for them to disconnect in terms of the bus powering them down.

Testing leopard on external drive & Up2Date

I had a few questions with installing leopard;
i have a 300GB harddrive (IDE to USB2.0) with about 200GB of data on it and I wanted to partition it with about 40GB for Leopard testing, is that possible to do and will it run okay via USB2.0 or can it not run on usb drives?
secondly i recieved Leopard as an Up-To-Date offer and it just came with the disc so i was wondering since it just says Upgrade on the disc does it mean its not the "ultimate" version as the retail copy or what??
thank you!!

You can't partition a drive without erasing the data, so unless you have a place to backlpu your 200GBs, then you'll lose it all when partitioning.
*"disc does it mean its not the "ultimate" version as the retail copy or what??"*
No, it means that a previous version of OS X must be installed before Leopard will install.

Installing Leopard on external drive then using as Internal

I have a family member that found a nice deal on a Macbook, but it has no HDD nor install CDs/DVDs. I want to buy her a HDD and then install Leopard on it and send it to her. I know that if you have 2 Macbooks, I can switch the HDDs from one to the other and the Macbooks will boot up on the HDDs. My question is, if I have a PowerMac G5 and I install Leopard (Universal Disc) onto a 2.5in HDD using an external case, will she be able to just pop it into her Macbook or do I have to install using a Macbook too? Thanks!

Can't be done. The machine she has must get the original discs from the owner.
If the original owner lost the discs, they must call AppleCare to get replacements for them.
Macs should never be separated from their discs. I warn against this on my FAQ*:
http://www.macmaps.com/usedrefurbished.html
You can't copy the operating system, as it is only licensed for your use on your machine.
As long as they are not in the same household that license only belongs to you alone.
And then if they are in the same household, you still need to buy them a family license so you can install it on multiple Macs.

Installing leopard to external drive

I recently had problems with an update last week. After the update, the computer would not start. I took it into the Apple store, they tried to reinstall the update (to 10.4.11) and were not able to get it to work. They suggested I buy Leopard, take that home and try installing it. It appears that I can get Leopard to install, but only with a full erase. I still do not have a computer that will make it past the opening gray screen without the Leopard install disk in the DVD drive.
This is where I am smacking my own fingers. I do not have a backup of my important files (I will change that post haste). I purchased a backup drive last night also.
Here is my question...
Can I install Leopard on the new external drive first. Then boot from the external drive (I saw them do that at the store last night). Then copy the important files onto the external drive (I only care about documents and music - I am fine with reinstalling the programs). Then erase and install the OS back on the computer. I did not purchase the multiple license version. Or is there a better method I do not know of? Once I have the computer fixed, the external drive will be just for backups (so I would erase the Leopard install and copied files from that drive).
Thanks

thanks,
CCC looks interesting but since my internal drive is not booting, I assume I would need to:
1) install Leopard to the new external drive
2) boot the machine from the external drive (don't know how to do that yet)
3) download CCC to the external drive
4) make a copy of the original drive onto the external drive
5) unhook the external drive
6) install Leopard on the internal drive (with an erase)
7) download CCC to the internal drive
8) hookup the external drive
9) use CCC to move the files from the external drive back to the internal drive
(except for the OS files - how would I do that?)
10) erase the external drive and use it as a backup for the internal drive!!!!!
(no more excuses for not backing up regularly)
Questions:
1) Is there a difference between CCC and "Time Warp"?
2) Is there a problem with cloning the non-working hard drive?
(It appears to physically be working, just not booting)
2a) If it is not advisable to clone the entire non-booting drive,
(due to problems with the copying back to the internal drive after
the clean install), is CCC any better/more useful than just using
file manager if I am only moving data files and no programs?
3) Is there anything funky about copying the downloaded iTunes files?
4) Did I leave anything out of my plan above?
I think I am close and can't wait to get home to try this.
Thanks,
David

Why can't brand new MacBookPro9,1 (OEM Mountain-Lion) boot from Snow Leopard on external drive, or internal partition?

Why can't brand new MacBookPro9,1 (OEM Mountain-Lion) boot from Snow Leopard on external drive, or internal partition?
Is this because of hardware changes? Or firmware changes? Or is it just and Apple Inc. administrative fiat?

@Steve Holton: Sorry Steve, but you're wrong about that one . I'm using 10.8 (purchased and downloaded) on the internal HD of this MBP8,3 (2.2 GHz, 17"), and I am also able to boot into 10.7.4 and 10.6.8 from external FW800 partitions.
However, I DO have problems with my MBP9,1. It came with 10.7.4 installed and ran fine. Then I purchased and installed 10.8. It ran fine but could no longer boot from 10.7.4 on an external partition. I then reinstalled 10.7.4 on the internal HD and discovered that it is still unable to boot (even 10.7.4) from an external FW800 partition.
One of Apple's Senior Support Advisors has done some remote troubleshooting but the case is still open and unresolved. An earlier Apple Support case suggested that when, I installed the downloaded copy of 10.8, there had been a "firmware update" (behind the scenes) that is now causing the problems with booting from my external partition(s). This apparently is "a bug": it is not what is supposed to happen.
So - I believe - "the problem" really has nothing to do with hardware capability. It is strictly about Apple's strategy for "managing its future customer base". If you don't like it - use something else - I am seriously considering Ubuntu as an alternative.
If there's a hidden caveat in all this it's probably "Read Appple's Licence Agreement VERY Carefully".

Apple Senior tech lady deleted all my external drive data while sorting out other problem. How can I restore all my photos , music etc back to my Mac Pro?(I am so scared, I haven't connected to sync! Please help)

Apple Senior tech lady deleted all my external drive data while sorting out other problem. How can I restore all my photos , music etc back to my Mac Pro?(I am so scared, I haven't connected iPhone to sync! Please help)

It was tele tech. I couldn't open my Page Numbers etc. Frist tech chat idiot - following dumping few things in bin, asked me yo upgrade to Yosemite. But the problem still persists. This morning I was asked to do it via telephone and like yesterday, after wasting 20 min, I was put to this apparent Tech Queen ( my foot!). She eventually decided to reinstall Yosemite asked me to connect my external drive while I connected to her. She was moving cursor asking me to move files and delete and I followed her like a dummy. It took 3/4 hours and she called me 3 times once the lengthy process was completed. I suspected from the beginng for the fact that why should be asking me to click all my backup from the very beginning! Eventually she said I deleted... Or someone else or may be my children ! It was a blatant lie. I run my small business from home and I was simply staying in front of the Mac whole day! Children were at school. Then she said I must have used another computer! I only have laptop and the iPad. I will talk to their manager first thing in the morning. In the mean time please let me know as to how can I transfer photos, music etc back to my laptop from my Iphone and IPad .? I am will connect to laptop as I am worried the new BLANK iPhoto may supersede iphone/iPad stuff? Will it? Please let me know. I am not a very tech savvy person. My son who could help me, is in Manchester Uni and Inam in London.

Load Leopard on external drive?

Is it possible to load Leopard 10.5.4 or Tiger on to an external drive that has been partitioned?
I want to keep my old Final Cut Express 3.0 version but at the same time load the update (version 4.0).
It will only load on a disc with a system.
If possible, how would that work with two systems running?

Assuming that you want to install them form the original disks, yes
If possible, how would that work with two systems running?
You would never have multiple OS running you select the start up volume with by depressing the "C" key during start up or by going to the system preferences and selecting a different startup volume

Leopard on external drive, whilst leaving current data alone

hi,
I wish to install leopard on an external hard drive, so i can keep Tiger on the internal computer drive. But I want to partition the drive for time machine as well, I have already used about 70gigs of 500gigs on the drive but i don't want to erase the data already on there.
If I use the split function in disk utility to create other partitions will it erase the data already on the drive or leave it alone and create other partitions?

it will leave the existing data alone so you can do that. just make sure you use the split function correctly (select a partition and click on +). However, I should add that it's a bad idea to have TM partition on the same physical drive with the system. if something happens to the drive you'll loose everything. get another drive for backups.

Install Leopard on external Drive?

I'd like to do what I have always done before when upgrading OSes, which is install Leopard on an external HD whilst I keep my existing Tiger on the internal HD.
This way I get to try out the new system without throwing out the old until I am satisfied the change is actually an "upgrade".
However I have heard this doesn't work with Leopard, you can not run 2 different OSes on the one machine and switch between them at startup.
Is this true? Has anyone tried this for themselves?

You heard incorrectly. Many here have done exactly that which you propose. I have two dual-boot machines - Tiger and Leopard. It does not matter whether the drive is internal or external. The only caveat is that for Leopard to boot on an external drive on an Intel box, the drive must be GUID.
For PPC it must be APS. Other than that, there is no problem.

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)

Can't boot snow leopard from external drive

I have a copy of snow leopard installed on a separate usb hard drive which I use to run some PowerPC programmes under rosetta. I can attach this USB drive to my Mac Pro and also to an Intel Macbook and choose to start up on this external drive without any issues. However when I try restarting my new 2011 iMac on this external usb drive the machine crashes every time with a kernal panic. Is this problem unique to me or does everyone else have this issue with new iMacs. Mine is a 27" 3.4ghz i& with 12ghb ram installed running 10.72. Is their soemthing I can do to resolve this problem?

I have now solved the problem of being able to boot from either Snow Leopard or Lion on a new Mid 2011 iMac. This is how I did it.
1. Attach an external USB drive to an earlier Mac or borrow one from a friend. In my case I used my 2009 Unibody Macbook (which has Lion installed on it but does allow you to install Snow Leopard on an attached device) Put the Snow Leopard install disc in this machine and tell it to install Snow Leopard on your attached USB Drive.
2. Start up the Macbook (or whatever machine you are using) and get it to restart on the attached USB drive so that it boots up in Snow Leopard. Then when Snow Leopard is up and running on the attached external drive, do a software update to bring it up to 10.68 (the current version). This step is important as I found that if I plugged in the external USB drive into the iMac with only operating system 10.6 installed it would cause a kernal panic on start up when I choose to start up on the external USB drive.
3. With Snow Leopard updated to system 10.68 you can now plug it into your iMac and restart the iMac booting into Snow Leopard from the external USB drive. You do this by either going to System Preferences>Startup disk and choosing the external drive, or by holding down the option key when you restart your Mac and choosing the external USB drive.
4. The next step is to make your iMac dual boot now that you know it can run Snow Leopard successfully from an external USB drive. To do this, go into Utilities>Disk Utility and select your main drive. Select the main disk (with Lion on it) and then choose Partition and choose 2 Partitions. Drag the first partition bundary line down to make the second partition size as small as possible. In my case I had a stock 1TB drive and the smallest partition size it would allow me was 70gb. Create the second partition (assuming you have spare space on your drive to allow this to happen). This will then create a second hard drive icon on your desktop. I renamed mine "Snow Leopard startup".
5. Download the free (and excellent) utility Carbon Copy Cloner and use it to copy your Snow Leopard operating sytem from your attached USB external drive to your new partition.
6. That's it! Now you can choose to start up your iMac from either Lion or Snow Leopard using either method mentioned in 3 above.
7. As a final step I suggest your install your Rosetta only programmes in your new Snow Leopard partition so that you can access them easily and keep them all together.

Lion to Leopard on external drive

I have Lion on my external drive and Leopard 10.6.8 on my iMac. I would like to move Lion to my main drive and keep Leopard on the external drive. How do I do this?

10.6.8 is Snow Leopard.
10.7 is Lion.
10.5.8 is Leopard.
Please confirm what you mean by Leopard.
Are you trying to do a 180 degree swap?

Installing Leopard on External Drive

Hi,
I have an external drive, ( western digital passport 120GB )
I was wondering if it was possible, to install Leopard on my external drive.. and boot from my external drive so I'll be running leopard from the external.
If so, can someone explain to me how I would do this?
and also, if I wanted to delete the Leopard system from my external drive, how would I go about doing that, so my macbook boots from its own hard drive again ( tiger )
thanks!

You first have to be sure the drive is bootable. Not all external HDs are bootable.
You will also have to partition it GUID or GPS since you are using an Intel box.
If it is bootable, Leopard will need its own partition, so you would have to temporarily put the other stuff on the drive somewhere else, partition the drive with enough room for Leopard and then put the other stuff in the second partiton. The Leopard partition should have a HFS+ filesystem that is journaled.
That's about it.
