OS X :: Booting From USB Snow Leopard Drive
Aug 13, 2010
I have a MacBook pro running Leopard (10.5.8). I am updating to a legitimate copy of Snow Leopard. I'm not installing from the discs, though. I made my flash drive a bootable disk, and I'm trying to install from the USB drive. I'm pretty confident that I did it correctly, but I am still having trouble. This is a brand new 8 gb flash drive. Using Disk Utility, I changed the drive to GUID Partition Table and formatted it to Mac OS Extended (Journaled). Then I restored my Snow Leopard .dmg to the flash drive. Everything seems to be going smoothly at this point. I clicked on "Install Mac OS X" in the newly created bootable drive, and after going through the next few windows it started installing. The progress bar increased to about 7%, which took probably five minutes.
After this, it stated something along the lines of "installation will continue after reboot," and then rebooted itself. When OS X started back up, it was like nothing had happened. No changes, no continuing installation, it was like the installation hadn't begun at all. I tried a second time and the same thing happened: partial install, reboot, then nothing but regular startup. The USB Snow Leopard Install Drive does show up in the list of bootable drives in the "Startup Disk" portion of System Preferences. Even when I select it as the startup disk and restart, OS X just boots normally almost like it's ignoring my direction to boot from the Snow Leopard install drive. When I hold "alt" during startup to select the drive to boot from, only the regular Macintosh HD is presented as an option.
I don't understand why it would show up in System Preferences>Startup Disk, but not show up when pressing alt at startup. I noticed in Disk Utility that the "Owners Enabled" option was set to "No," so I used Terminal to change that to "Yes," even though I'm not sure it makes a difference at all. I named the USB Drive "Snow" and entered the line 'sudo /usr/sbin/vsdbutil -a /Volumes/Snow' in Terminal to do change owners enabled to yes. So this is where I am stuck. From what I can tell, I think I created the bootable usb drive properly, but I can't seem to boot from it and running the install off of the drive while already logged into OS X halts at about 7% and reboots.

I have Snow Leopard installed on an 8GB Flash Drive. It works all good and fine. The only thing is I don't want to do an upgrade, I want to do a FRESH erase and install of my machine (macbook). I tried plugging in the USB drive and restarting the computer while holding down "c", this proved to not work.
Any way that I can erase the computer completely and fresh install from my USB drive?

I know this has been somewhat covered before but.Should I be booting into 64-bit Snow Leopard?I have a 2008 Mac Pro with 16GB of memory.I mostly run Photoshop CS4, X-Plane, QuickTime 7 Pro, Compressor and FCP6.
I know you hold down the 6 and 4 keys but is anyone using either "Happy Cat", "K64Enabler 1.0.1", or "32- or 64-bit Kernel Startup Mode Selector 1.2.3" to enable 64-bit Snow Leopard?

i just bought a new uMBP 15 2.53 last night and i bought a Seagate 500GB 5400rpm HDD to replace the one on board. I installed the HDD and SnowLeopard install went through great but after install every time i boot up, it takes a long time on spinning gear. It eventually loads up but takes a while, I ran Repair Disk Permission and Verify disk and everything turns out fine. I even ran Apple hardware test on HDD and tests passes. I haven't installed 1.7 EFI Firmware since i've read that it doesn't work so well with third party HDD or doesn't work at all.

When I turned on my 13 inch Macbook this morning I got a black screen with the message "No bootable disk, insert startup disk and press any key". This has never happened to me before and I am wondering what the cause is and how to avoid it in the future. I got the system to start by pressing and holding down the option key.

What I have done already is restore my USB Flash Drive with a .dmg of Leopard using Disk Utility. The next step consists of booting Tiger into Leopard by holding down the option key at start-up and selecting my flash drive. The USB flash drive comes up on my computer as a Leopard Install DVD but when I hold in the option key during start up, I do not have an option for my flash dirve to boot.

Environment clones ( made by Leopard compatible SuperDuper and Carbon Copy Cloner) to two separate LaCie Firewire drives will not boot from those drives Leopard (10.5.6) running on an old 14" iBook G4 1.1 GHZ. Both SuperDuper and Carbon Copy Cloner declared the clones bootable, and they are selectable as Startup drives. All three drives (internal included) are partitioned using Apple Partition Map and OSX Extended Journaled. Has anyone met and solved this problem? BTW - I did read somewhere that Leopard is designed to use the GUID partition scheme; but this is of no use with a PPC Mac. Could this be the source of the problem?

I ran a disk check on my MacBook Pro which told me to run disk repair. Since this was my boot HD, I took out my Installation DVD, put it into the running system and started the installation file then selected that I wanted to reboot and start utilities. The system then rebooted, the "chime" came, and then, silence, gray screen with apple logo, nothing is happening. What do I need to do, to get further and repair my hard disk?

I am using a 2006 Intel Xserve (10.6.8) at home for storing lots of multimedia. My 2 TB user drive, which is inside of one of the Xserve's drive caddies is nearly full. I purchased a $157 3 TB Seagate Barracuda (Model No. ST3000DM001) from Amazon and put it inside the caddy. It is not being recognized at all. Looking around for solutions I am getting a hint that trying to restrict the data rate to 1.5 GB/s might help, which is documented for some of Seagate's older SATA drives, where one puts a 2-mm jumper clip on a header next to the SATA connector. This 3 TB model has the same header, but the manual only speaks of data rate autonegotiation. I'll be able to try out the drive with the jumper clip in place tonight and will report back. Curiously, in my Thermaltake USB-2 interface (toaster style), Disk Utility shows the drive as "801.57 GB Generic External Media," which is being discussed in a Leopard Server discussion thread. Last I saw, there was no good explanation for this symptom.Â

I recently bought a new hard drive for my 2006 MacPro, intending to use it as a new startup disk. Trouble is, the drive it replaced, a 2TB drive has too much info I want to keep to move it out and reformat. So I figured if I deleted all of the old system files I'd be ok. Since then I've been plagued with problems, mostly permissions changing in the core services folders. There are other minor issues as well, like my apple keyboard function keys not doing what they're supposed to, and if I accidentally hit the eject button in the menu bar I get the beachball of death, with no way to force quit.Â
I have done everything I could, and a lot of research, and I stumbled upon the answer. In the startup disk utility "Reset password' I noted that the admin account, and user account from the old drive were still being recognized as existing. So basically it's like my computer is having an identity crisis!Â
I've been searching for a way to get rid of those phantom accounts, and my best lead turned up some apparent glitch in Leopard regarding old accounts. But how to get rid of them? It would be very difficult for me to safely backup the sheer amount of data on that drive in order to reformat, but I can't seem to find how to rid myself of these accounts. I tried logging in as the root user, but didn't see any tell-tale files on that drive. Â

So I have a MBP Early 2008, and the dvd drive has died (still under warranty, just don't want to get it fixed at the moment)
Also have a Mac mini WITH a working dvd drive. Anyway I tried the dvd drive sharing. I can see it on my MBP, even open the disc, but when i double click the install mac OSX icon, NOTHING happens.
So I used toast to make a DMG, and transferred it using my USB drive.
Managed to open it on my MBP , but when I click the icon again, this time it says not supported or some error message.
Any ideas what is going on, or if there is an alternative method I can install ?
The disc works fine on the mac mini, and the installer starts fine (but I am not upgrading that one at the moment)

Sounds like people are enjoying Snow Leopard. I would love to join them, but the installer can't see my system drive! Disk Utility doesn't see it either. The only possible issue is that my system drive is an SSD, but it would be impressive if Apple managed to make their OS incompatible with a drive with a perfectly standard interface. Anybody else managed to get Snow Leopard installed on an SSD, whether one that came with their system or one they installed themselves?

I've got a 500gb drive in my MacBook, check out what comes up when i quick-view my home folder, apparrently Snow Leopard has got a new feature of doubling your disk space now! Anyone else discovered this 'feature'? If only it were true...
*EDIT*
OK, do ignore this thread! I've just realised it's prob because I'm running file-vault so it's using a disk image for my user folder! Sorry for the excitable 'bug report'!

Ok so sometimes I like to watch HD movies on my Xbox from my external usb hard drive that is formatted HFS+. I heard that formatting with Snow Leopard frees up that extra bit of HD space so I thought i'd try it. Well it sure did free up the space - after the erase/reformat there was 249.4 GB out of 250 GB (normally after a reformat there's only 232 GB out of 250 GB). So I go to plug the usb hard drive in my xbox 360 and it didn't recognize it. WTF? So then I tried to reformat it back to HFS+ with Macdrive on Windows but it still isn't recognized by the xbox.

Well I just upgraded my computer to snow leopard, and I am very happy. It went very well, and was incredibly easy. I haven't run into one problem as of yet. No compatibly issues, no spotlight problems, nothing. I also heard of people complaining that snow leopard was very slow when they upgraded and didn't do a clean install, well for me, I noticed a speed increase over leopard, and I just simply did an upgrade. I am very pleased with this new OS. I think apple did a very good job refining leopard. I just thought id share this with people, so they don't always have to read the things going wrong with an upgrade over a clean install. Not sure if it matters, but I installed off of a usb drive.

I am trying to defragment the hard drive using snow leopard but I get the following message:You cannot use this algorithm on the selected volume. Off-line algorithms need to unmount the disk so you need to boot from a different disk, partition, computer or CD/DVD. Alternatively, use the Quick (on-line) algorithm.How would I do this without doing a quick algorithm? Basically how do I unmount the disk or boot from a different disk or DVD and run this program, iDefrag.

One morning my Mac Mini would not startup, it would try to start up but after about 2 minutes the Apple would turn to the circle with a diagonal line through it. Fortunately I had installed Snow Leopard on my external Firewire 800 drive so I could startup from that drive. My internal drive now will not mount when starting from my external drive until I rebuild the drive using Drive Genesis and then run Volume Structures with Tech Tool V5.0. No other combination of utilities seems to work to make it mount. Not sure if that would makes sense to anyone that might know what is wrong and how to fix it so I could startup from my internal drive.Â
I have also tried to reinstall Snow Leopard but when starting from the install DVD the internal drive does not show up as an option for installation. I am trying to startup at least one last time from my internal drive since I have a Filemaker Pro 7 database which I have forgotten the password for but when starting up from my internal drive it opens since the password is stored in Snow Leopard. I have found programs using Windows to change or extract the FM7 password but I am trying not to spend the $30 to $40 for a program I will only use once.Â

When signing in to macbook, which is network connected, tries to connect to a non-existent NAS server (used to exist but replaced). Gives message that 'NAS server cannot be found', usually at least twice. Message(s) can be canceled without a problem. Then when opening Chrome, same message appears again. System is obviously retaining this old location somewhere within a setting, but do not know how or what to look for.
