OS X V10.5 Leopard :: Boot From USB Drive Using A Lion IMac?
Jun 29, 2012
I'm looking to wave good bye to my MacBook Pro running Leopard and upgrade.Â
However, I need to keep a version of Leopard so I can run certain Audio Units that won't run on Snow Leopard or Lion.Â
I have made a bootable drive with Leopard on it, but I can't get it to boot on my iMac running Lion. It boots fine using the MacBook though.Â
Is what I'm looking to do possible any more, or do I need to configure the drive for use with a Lion machine somehow?Â

I have a 1Ghz PowerPC G4 iMac and want to delete everything and start again with Leopard. (it seems to be within the system reqs.) Problem is the DVD drive isn't functioning properly. It sees the OSX DVD but won't boot from it. Question - What's the best alternative method? Create a boot firewire disk?

Last week I finally upgraded from 10.6 to 10.7, but now my Mac Pro (2008) won't boot properly. It'll start to boot with the gray screen and the Apple logo, but then the entire screen goes gray and it just locks up there.  However, if I reboot and hold down the Option key to bring up the list of bootable drives that works fine. I've checked my Startup Drive settings and the proper drive is selected. why it won't boot on it's own anymore? Holding down the Option key is getting old.Â

I have installed my hard drive from a previous but terminally I'll iMac that was running Snow Leopard into a Sata to USBÂ enclosure. This is displaying on the desktop of my new iMac running Lion as an external Hard drive,also system preferences sees it as a start up source.My question is , is it safe to restart into Snow leopard without causing a kernel panic and if it does boot will it be fast enough to use as it as a USB drive.

I'm using a 20" white intel iMac and cannot manage to remove a linux boot disc from the optical drive.At first, the only way that i managed to boot to the linux disc in the first place was from the Startup Disk menu in OSX. I could not even get to the Startup Manager ('opt' at boot) or boot straight to the disc ('C').Now i'm in a position where no matter what i do, the system boots to the linux disc. I cannot even force the startup into OSX to try to eject the disc from there. I've tried holding all of these keys/combinations at startup

I have:
-one iMac with cracked screen -- currently being used via dual monitor setup
-one new MacBook Pro (running Snow Leopard)
-a legitimate, family pack DVD for Leopard
I want to:
-reformat the iMac and install Leopard on the iMac via Target Mode/firewire using the DVD drive on my MBP
However, when I try to boot the MBP from the Leopard DVD, nothing happens.
I know this is kind of a mess, but it's the only viable solution I have been able to come up with. I can't install Leopard on the iMac from the Leopard DVD because I can't see the screen (due to the huge crack on my iMac) and it does not show up on the extra monitor.
Is there a way to safely force the MBP to boot from the Leopard install DVD?

Does anyone know if it is possible to create a disk image of the boot drive? I have tried / boot from DVD, then go to Disk Utility, file/ create new image from disk but the process stops imediatlly with a. cant unmount drive, b. drive is busy, c. in use how the drive is in use is not sensable, as it should be as 'just a drive' This is on a laptop with OSX 10.5.8 / 32gig hd, 2 gig ram, just in case it matters. I thought about timemachine, but the laptop sometimes requires a complete reinstall, that is a long process, install + upgrade + redo all the other programs + Â

I have the first gen aluminum iMac and I think my optical drive is pretty much dead. It makes this horrible scratching noise whenever I put a disc in and it'll try to read for half a minute before spitting it back out. Sometimes it even freezes the computer. Anyway, I'm just planning on getting an external USB DVD burner. Does anyone know if I can boot off the USB DVD drive?

I have no id� whats wrong, I want to install Snow Leopard(from the external) on my Core2duo Macbook pro, which is running Leopard at the moment.
I have a Snow Leopard image, and I have used Disc utility to partition the external hard drive (GUID), and I assume the partition and install went well on the external, because in Disc start the external appears as OSX 10.6.
Then the problem: The macbook wont boot from the newly made external it just gives me this sign (of course without the colours).
I have tried to start the macbook normal, and with the option key held down were the external pops up.
I have also tried to chose the external in disc start and reboot with no luck.
I have tried to start the Snow Leopard install(external) within Leopard where the install start fine, but when it reboots and wants to continue the install, the sign appears.
The external harddrive is a 5400rpm 40gb 2,5" which is only powered by the usb port maybe thats the problem?

After many unsuccessful rounds of burning to DL DVDs and flash drives, I settled on making my iPod bootable and running it from there.So I'm excited and running my startup disk on my MBP as the iPod and I've connected my MBP to my iMac G5 PowerPC through firewire and enabled target mode. After booting into the iPod, it gave me the option to install to the new hard drive from the iMac G5 (which is currently connected to my MBP). I installed it through my MBP, and assumed it had installed to my G5.

I have an Intel iMac with with Snow Leopard and Windows 7 on separate partitions. Recently I have acquired an external USB hard drive. I formatted it with Ext4, and installed Linux Mint to it.
The installation went smoothly, but I can't seem to boot from the USB drive anymore. Holding down Option on start-up only gives me two choices: Mac OS X and Windows. The drive isn't recognized in either operating systems anymore: on Snow Leopard I get "The disk you inserted was not readable by this computer" and on Windows, it doesn't even show up in My Computer.

My Intel based imac (purchased in Sept 07) won't boot up because there's an unreadable movie dvd in the disc drive that won't eject... when I turn on the computer, all that happens is it plays the opening chime and displays a white screen... I'm wondering if someone can help or suggest what's going on: Basically I put a movie dvd in my imac that my regualar dvd player wouldn't play so I thought I'd try it in my imac. Once inserted, the disc drive tried to read it but it wouldn't mount, it just made an odd spinning/grinding sound. It wouldn't eject using the keyboard eject button so I shut down my computer so that I could call a friend to ask for advice.
My friend gave me several options to try - holding the left mouse button at start up, hold C down on keyboard, command option O F to open firmware, reboot pram but non of them work. Basically when I start my imac it immediately tries to read the unreadable dvd and doesn't get to the normal start up procedure, it just shows a white screen and chokes on the dvd. Is there a way to manually eject the cd or does the machine have to be opened up and the cd physically removed? Is it likely that my imac will start up normally once the unreadable dvd is removed? I hope my hard drive hasn't gone bad because I haven't backed it up in a long time... Is there a strong possibility that my hard drive is toast?

I just ordered a new iMac and I'll be upgrading from a 1GHz TiBook with Tiger on it. I have some important music software that I'm not 100% sure will work with Snow Leopard, but my understanding is that it's already ok for Universal Binary. So I had the thought that maybe I could put Tiger on the iMac and dual boot. I've never dealt with a dual-boot system before, other than a couple times when I played around with Classic Mode when I still had Jaguar and/or Panther.

Since I do development, I want to keep my iMac G5 at 10.4.11 (Tiger) while having 10.5.2 (Leopard) on an external drive for booting and customer support (in the meantime anyways - at some point, I may move the internal to Leopard and keep a version of Tiger on the external drive for customer support).Sounds none too difficult to achieve this. Attach external drive, insert installation CD, and follow instructions.
One thing that alludes me is the best way to make the applications available on the external Leopard boot. Can I just run them from the internal drive or will they need to be copied/installed on the external as well? Any really clear and useful resources on this type of thing?

1. I do occasional maintenance with onyx and have been getting a few startup disk errors in recent months. These seem to get repaired and the computer still functions as normal. I have never had these before in 8 years of using osx so they do worry me. Is the osx boot drive just a bit corrupted? Would a simple reinstall help or is the hd showing signs of failure?
2. The trash simply refuses to empty. The operation can�t be completed because you don�t have permission to access some of the items.
I've tried to bring the items back to the desktop and the folder they came from but they simply make a copy of them. I've tried the option key method and sudo rm -rf ~/.Trash + sudo rm -rf /Users/user_name/.Trash in the terminal but get no change

I am unable to boot lion from an external drive on both a MacBook Pro mid-2009 and an iMac late 2008. Both have lion installed and I would like to boot from either a FW drive or USB key. I have reformatted both a FW drive and USB and set them to GUID and installed lion but I can only boot them to the Disk Utility App (drive shows up only as 'EFI Boot' when I hold option down).Â
The firmware is up to date and I also reset the PRAM. I am able to boot both computers from an external USB Snow Leopard drive.

I have just installed a 240GB LaCie Little Big Disk Thunderbold SSD as a boot drive for my 2011 iMac (which contains only the 7,200 prm HDD). This has improved read/write speeds dramatically. I have transferred all my data and applications to the external drive in order to see the full benefit of the SSD.
However, I had not considered Time Machine. I thought it would simply be a matter of identifying the external drive and then connecting to the Time Capsule. However, the external drive is not visible in Time Machine set up and I suspect there could be a good reason: that it is not possible.

So I'm having problems with my setup, and looking to find a possible remedy. I have setup my Mac with a 120G SSD in my main drive bay, and moved my 750G HHD to an optibay setup. I booted off a USB copy of lion to install it on the SSD, used migration assistant to move my things over. Â
So currently it boots off the SSD (named Boot Drive), has a "boot user" with its home folder on the SSD, and has my old user (lets call it "olduser") on the orignal drive HDD (called Optibay) and I created a new user when logged into the "boot user" with the same name "olduser", and moved its home directory to the old HDD path, /Volumes/Optibay/Users/Olduser. Then I deleted everything except the user folder on the HDD.Â
BUT, I'm having spin up issues, and constant read/write on the HDD in the optibay even on the boot user, and at times it shouldn't be. I have moved my files around enough that I can now fit the "olduser" onto the SSD, (moved the contents of Movies, Pictures, Documents, and Music folders into new folders @ /Volumes/Optibay/Myfolders). Â
So how do I move the home folder/user from the HDD to the SSD. I can't quite figure out the best way to do it with preserving all my settings and everything that is at the root level on the HDD to the SSD. Trying to preserve permissions seems to be the biggest issue. Should I be logged into "olderuser" and copy the user folder onto the SSD, then login to the boot user and just change the home directory path to the new one? Or should I be logged onto boot user when I make the move? The end goal is to make the optibay drive ejectable while running on my olduser account so I can get it to spin down

I tried running blackmagic design's disk speed test on our Mac pro ssd boot drive only to be told that the drive was read only. looking at the disk info I saw this:
admin: r&w
system: read only
wheel: ro
everyone: ro
I changed system to r&w to allow me to use the disk test. I would have expected to see (me) somwehere in the access list but I'm not there and I can't add myself. Is there a way to rest the drive's permissions to the default settings? Or what is the best solution to wipe the drive and start over?

Prior to upgrading to Lion I used SuperDuper to create a copy of the existing internal hard drive on an new external drive (iOmega eGo 500GB). Tested booting from the external disk and it appeared to work correctly. Upgraded to Lion. Several days later attempted to boot from the external disk (by setting the start up disk in the system preferences) but it fails. The system always boots into Lion.
What I've tried: Setting the start up disk through system preferences. Holding down the option key to select a disk on startup - interestingly enough I only see the internal hard disk and a recover HD. No sign of my external disk. Using a clean partition on the external hard drive I installed SL from the retail DVD. This produces the same effect of system booting to Lion on the internal drive, which suggests that the problem is not related to the copy I made using SuperDuper, but rather has to do with the external drive or something in Lion that prevents using an external drive (but I've never heard of such a thing).

I have two Macs that run Snow Leopard. Lion looks to be quite different and offer great new features, particularly the app store. So, can a Mac become dual boot like a Linux can? I mean, may I co-install Lion side by side with Snow leopard rather than overwrite it? I have successfully done this operation on a Linux Ubuntu netbook with two different versions of Ubuntu, and a Windows 7/Ubuntu netbook. But I've never tried this on a Mac. Does a Mac OSX install allow options for how the user will install the new OS?

I have a Macbook Pro from 2008. It previously just had one partition, with Lion on it. Â
I created a new partition for Snow LeopardÂ
I installed Snow leopard from a retail disk on the second partition. The installation went fine, and I got the message at the end that the installation was successful, and to restart the computer. Â
When I restart it, it just goes to the gray Apple screen, with the spinning gear, and never gets farther than that. The gear is spinning. Â
I can still boot successfully into Lion. Once I booted into Lion, I chose the Snow Leopard partition as the Startup Disk, but the same thing happens - just the gray Apple screen and spinning gear. I've let the machine sit for half an hour in that state, but it still does nothing but the spinning gear.Â
why I can't boot successfully into Snow Leopard and how I can fix it?Â
