Can I install OS 9 on an external Firewire drive?

I am not sure if this belongs in the G5 thread or the Leopard thread. Anyway:
I have a Mac G5, running Leopard 10.5.4.
I understand that Leopard will not run Classic applications.
*However, can I install OS 9 on an external Firewire drive? And just boot directly from that drive?*
I have essential OS 9 apps that I really need to keep.
I am aware of Classic emulators that run under Leopard, but that is not an option.
Any advice, insights, suggestions, et cetera in this matter will be appreciated!

+PS I should have added for the sake of others reading this thread…+
You, Dunestrider, can run your Mac in Tiger (and hence in Classic) because, AFAIK, your G5 originally shipped with Tiger.
Others should be aware that you cannot boot a Mac with an OS earlier than the one with which it shipped, i.e. if your Mac shipped with Leopard you cannot do what I suggested in my previous post. See this Apple doc.
Also, Dunestrider, I just realised belatedly that you won't have to buy Tiger - you will still have the original Install disk(s) that came with the G5.

Can I install a program on an External Hard Drive?

I have an 500 GB external hard drive that I attach to my MBP to store movies and my aperture picture libraries. When I first got it, I created three Mac OS Extended (journaled) partitions, one for movies, one for pictures and the other one for “extras”. I’d like to install Adobe Photoshop on my external hard drive, so I’d like to know if there is a way to make any one of my three partitions operate as if they were a system partition. Can I install an application in an external hard drive? Can I run an application from an external hard drive? Which formatting solution could help me achieve what I want? Is this even possible? Any suggestions?

There are many applications that are happy to be installed on a partition other than the boot partition. However, if the Adobe Photoshop installer does no present you with that option I wouldn't. You could always copy it across post-installation to see if it will work. Updating my present issues.

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.)

Trouble with installing 10.5 from an external firewire drive

I have a family pack of 10.5 and installed it just fine on my macbook. But, I'm having trouble getting my imac DVD player to read the DVD. It just spins and spits it out, and spins and spits it out. The imac is not covered under applecare so spending money to get the DVD drive fixed (which I barely use) is not something I want to do right now.
Anyway, I followed instructions on a this website to install 10.5 from an external firewire drive. (http://iuseapple.com/blog/apple-how-to/advanced-os-x/2007/10/29/how-to-install-l eopard-from-external-firewire-hard-drive/)
But I get stuck and am not able to actually get my imac to boot from the installer. Basically, I am able to use disk utility to create a copy of the disk image on my macbook. That resulting file ends in ".cdr" and it mounts when I double click it.
And I partitioned my firewire hard drive without problems.
I think I'm messing up when it comes to doing the restore. If I try to drag the .dmg mounted file in to the "source" it doesn't work (is greyed out). If I try to drag the mounted .dmg there than it works, but I get an error when I click "restore" (something about scans and images not being found). I tried physically copying the .dmg file onto the partition, but then when I plugged the HD into my imac, I wasn't able to get the imac to boot from the installer.
What am I doing wrong? If someone could walk me through these last steps I'd appreciate it!

Okay I finally got around to creating the bootable disk image of 10.5 using Carbon Copy Cloner. Still my iMac is not booting from the firewire drive!
Here's a recap of everything I've tried. I'm at a complete loss now!
- I partitioned the HD into 2 partitions-- a 10gig one for the 10.5 install, the then the rest for Time Machine. I make the partition in Disk Utility on my MacBook.
- I've partitioned the drive a few times-- always partitioning it in APM format (b/c it needs to boot my non-intel iMac).
- I've created the disk image using "restore" in disk utility. I've again tried this a few times.
- I am able to boot my MacBook from the disk image I create! So I know the FW drive is able to be used to boot from!
- Here's what I've tried in terms of getting the iMac to boot from the FW drive. It always just boots to my internal drive instead. Sometimes I briefly see a folder and question mark. I've tried all 3 FW ports. I've selected the install partition at start up in preferences. I've also held down the option key at start up (only my internal drive shows) and I've held down command-option-shift-delete and again I get the question mark and it boots to my internal drive.
- And I installed Carbon Copy Cloner and made the disk image that way on my macbook. Still, I tried everything and the iMac is not able to boot from the firewire drive!
Since my DVD drive is broken, this is the only way for me to install 10.5! Help!

HELP! - Error 1309 - Can't copy file over 10gig to External firewire drive.

I know this is more of a hardware issue but I know that only other final cut users would be copying single files over 10gigs.
I have a G5 that I use for video production. Video Files can be large and to back them up I got an external hard drive ( Maxtor 1-touch 200gig) When I try to copy a file on to it that is 10gigs it give me a 1309 error. I have found that other people have had trouble copying files over 2gigs over to an external firewire drive. But I haven't found any answers. Can anyone offer any advice on how to solve this?
Thanks

If you don't want to format it for the mac, you are limited to file sizes under 2gb.
Another alternative is to hook a firewire drive to your Mac and then share it with your windows machines (the program SHAREPOINTS is useful for this).
The drive can then be formatted Mac OS Extended and, once shared, the PCs can access all files without size limitations.
good luck.

Can WinXP be loaded and booted from external firewire drive?

The subject line probably says it all but:
Does the recent firmware upgrade and/or BootCamp allow you to install WinXP on an external Firewire drive rather than partitioning the iMac Core Duo's internal drive?
Mike
Intel iMac Mac OS X (10.4.6)

The other problem is XP itself doesn't support booting from firewire. Even if someone could figure out how to install to an external from bootcamp, you would still have to contend with XP.

I have an older MacBook Pro using 10.4.11 and want to use new operating system to use the latest iLife. Can i install 10.7 on an external hard drive and use the external hard drive to run new system while leaving my old system intact?

I want to use a new version of iLife (for iMovie and iDVD) but am currently running OS 10.4.11, which won't work with the newer iLife programs. Can i install OS 10.6.3 or 10.7 on an external hard drive, boot to that hard drive and work with the new software (installed on the external hard drive) using my MacBook Pro (circa 2005/6) as the engine while leaving my laptop running 104.11 the rest of the time?

Yes, you can use an external drive. To upgrade, however, means:
Purchase Snow Leopard DVD then update Snow Leopard to 10.6.8.
Access the App Store with your Apple ID and purchase and download Lion.
Your computer must meet system requirements:
Snow Leopard General requirements
Mac computer with an Intel processor
1GB of memory
5GB of available disk space
DVD drive for installation
Some features require a compatible Internet service provider; fees may apply.
Some features require Apple’s MobileMe service; fees and terms apply.
Lion System Requirements
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space
Some features require an Apple ID; terms apply.
Obviously, you do not have to upgrade to Lion but can stop at Snow Leopard 10.6.8 which is sufficient for the current versions of iLife apps. Note that iDVD is no longer part of the newest version of iLife. Lion 10.7.2 or later is needed should you wish to use iCloud.

Can I install Snow Leopard with an external disk drive?

I have been trying to update my software to Snow Leopard but I am using an external disk drive and when I try to install the software I get the message "The application 'Install Mac OS X' cannot be used from this volume". Is there any way to fix this problem?

Are you booting your computer from an external drive? If so please say why? How are you trying to upgrade to Snow Leopard? Do you have the 10.6.3 retail Snow Leopard DVD? On what drive are you trying to install Snow Leopard? Are you doing this?
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Install Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with installing OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1. Then use Software Update to download and install any other needed updates for Snow Leopard.

Can we install Windowns XP on a External Hard drive?

Hi,
Can we install Windowns XP using boot camp on a External Hard drive?
PD: My external Hard drive is formated on Os and IT has a Firewire 800
Thanks,

The Instruction Guide which you will find if you Open the Boot Camp Assistant states that Boot Camp can create partitions for Windows on internal drives. So if you had a Mac Pro with multiple internal drives Boot Camp can create a partition on any of those drives with space available or even an entire drive.
Just an idea for you. There is an entire Apple Discussion forum dedicated to Boot Camp and Windows.
Whereas, not everyone here with an Intel iMac has installed, tried to install or has experience with BC & Windows, everyone there has or at least has an interest. You may attract help more quickly there.
The Forums are at the bottom of the main Apple Discussions page under Windows Compatible Technology. Here is a link;
Boot Camp: Installation and Storage

MBP Late 2010, How can I install Win7 Boot Camp using External Optical Driv

Hello:
I have a new MBP purchased in February. It's not the 2011 model. I replaced the Optical drive with an SSD drive and put the optical drive in an external enclosure. The Optical drive works great, reads, writes, etc. My Windows 7, Pro 64bit DVD works also, tested on a PC.
I use the Boot Camp assistant to create a partition. It them reboots and never starts up from the optical drive. I get an Apple logo alternating with a stop sign.
I have got back to OS X by starting with the Option key and choosing my OS X volume.
I tried booting to the DVD by using the option key, that did not work. I then choose the EFI option which allowed me to hit any key and appeared to boot from the external optical drive. Windows setup screen came up and I hit enter to start the file loading process. It eventually stopped when the progress bar was all the way across the screen. Then nothing.
Questions {Please give definitive answers, not guesses, thanks :)}
1) Is it possible to setup a boot camp Windows installation without an internal optical drive? Yes/No.
2) If yes, how?
3) I see the rEFIt utility has helped some but I read mixed reports. Will this help me boot and run Windows setup from an external optical drive? I don't want to install it if it's not known to be a certain fix.
4) Is my only options to reinstall the optical drive?
I chatted to OWC the vendor that sells the bracket. They had no idea how to install a Windows BC partition without an internal drive.
I am seriously discouraged by what seems to be Apple wanting to control everything. I had a Mac Pro and Air book in my future but now, it's on hold.
Thanks in advance,
Kevin

I tried what you are doing with a 2007 MBP, and could not get any Windows CD s to boot from an external optical drive, firewire or USB.
I think this is fundamental to Windows which won't boot from an external USB drive either even on a Windows machine (although I believe there may be complex ways of achieving this). I don't think this is Apple trying to control the world.
I ended up taking the MCE Optibay out and putting the original optical drive back in.
Just possible that something has changed between a 2007 MBP and 2010 MBP, but I doubt it.
If you want the second internal HD, you have two options:-
1. Put the Apple optical back in, install Windows, then take out the optical and refit the SSD. The external optical will still be able to install windows apps and data etc, just not boot any windows install CDs or utilities (like Paragon rescue disks). You will not be able to do a Windows repair install without refitting the optical.
2. Parallels, which has come a long way in the last two years. I am 99% certain that Parallels will install from an external optical.

Can I install windows 7 to an external USB 3.0 drive via bootcamp?

with the new airport extremes supporting USB 3.0, can I install windows 7 to an external USB drive via bootcamp?
i'm not willing to sacrafice any of the limited space on the SSD, but i'm very willing to get a good performing USB 3 drive, and use it as necessary with windows.
if this wouldn't work via bootcamp, can it be done on a windows PC and plugged in subsequent to the install to work on the road?

Installing Windows on an external drive is not supported.

Can I install Boot Camp on an external disk?

I have a MacBook Air ( version 3,2) and I am running out of space to install Boot Camp. I use Windows 7 by the way.
Can I install Boot Camp on an external disk? How do I go about doing this? I have an Apple external super drive and I have two USB ports on my computer.
Can I install the mac operating system on the external disk including the Applications and then install Boot Camp as per usual? How would I get the Windows 7 program to install on the external disk using the superdrive that I have?

BootCamp will only install on an internal disk.
If you are wiling to do some work, do some Google searches, use third party tools, and make your own custom Windows install disc, then you might be able to get what you want, but there is no guarantee that it will work on your specific hardware.
I researched this topic a year or two ago and found people claiming that using rEFIt and custom built Windows install discs, that they were able to do what you seek. After reading through all the instructions, I found it much easier to upgrade the HD in my MacBookPro to a 500GB drive and just installed my BootCamp on the spare 180GB space from the upgrade. That took me a little over an afternoon, and it was fully supported...

Can I install my OS on new external dvd/cd drive

My hard drive died at the same time as my internal cd DVD drive. So I'm thinking of buying the OWC Mercury Pro Dual Layer DVD+/-RW Pioneer DVR-218L
External DVD/CD Writer (http://eshop.macsales.com/item/OWC/MRF82SD22B/) but need to know if it's going to work automatically. Obviously I can't install it if my OS isn't even installed!

You can't boot the computer from a external DVD drive.
If you can find another model Mac just like yours, then c boot off your installer disk and HFS+ format a external drive and install OS X onto it, you can take that and hold option boot the sick Mac from.
Also once you get the internal drive replaced, you can use that external drive to Carbon Copy Clone the OS right onto the internal drive, no need for a internal DVD drive replacement, then you can use the external DVD drive.

Can I install PS CC on an external HDD for portability? [was: Retire01]

Can I instal PS CC on an external HDD so that I can take it from place to place??

When you activate Photoshop (most likely CC too) Adobe's activation servers write hidden credentials onto you system. Most likely these are on you system boot drive. Also when programs are install onto a system many settings for the Program are recorded into the Operating System Configuration. So If you install CC onto an external drive though the programs install tree will be on the external drive many system configuration and authorizing files will not be on that drive.
