OS X V10.6 Snow Leopard :: Can't Startup With An Internal Drive

Mar 25, 2012

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. 

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.

OS X V10.6 Snow Leopard :: Reload To Internal Drive / Unbootable

Mar 30, 2012

Made a few missteps while cloning my drive to an external destination.I need to get my internal drive reloaded. Preferrably with a clone BACK. I keep getting kernel panics & cannot boot from what I have managed to clone back.cloned my drive (formatted SL X.6.8) to an external USB (yes, its a tad slow) in order to test drive my applications on Lion.This was done using Intego's Personal Backup. The backup wound up being unjournaled.Made a stupid mistake allowing the internal drive to be optimized by TechTool (it was journaled).I assume this could be the first cause of my problem.Since that internal partition would not boot any longer & the icon would not show, I used Disk Utility to repair the volume.The volume is a partition on my internal drive. The second partition is formatted for Windows. that's intact.After repairing, the icon is back.Apparently you can only back up Time Machine back to the original drive FROM the original drive (?). AlthoughI am not very recent in Time Machine backups, having turned it off a few weeks ago anyway.I then tried to clone BACK to the internal using CCC. It seems to have put the folders back.On start up I have the options of External clone (not the actual name), Windows partition, or "EFI" which may not be theinternal, rather a TechTool Boot of some sort.I'm going to try & retrace the same step - of clearing that internal partition & try to load a clone from the external clone one more time,to see if it becomes bootable.

OS X :: (snow Leopard) Cloning External Drive Doesn't Match Mac Hd In Gigabytes

Apr 25, 2010

when i clone my mac book pro (snow leopard os) hard drive using SUPER DUPER, the cloned external drive doesn't match the mac hd in gigabytes. my mac hd is max 250 gigabytes, my external drive clone is max 320. however the mac hd reads as 233.71 gb used, and the cloned ext. drive reads as 216.54 gb copied. shouldn't a cloned drive be exactly the same size as the original drive (mac hd) that's being cloned?

MacBook Pro :: Unibody Boot From External Drive But Not Internal?

Aug 7, 2009

I started this situation with a bootable hard drive that I removed from a 4,1 (mid 2008) and a brand new unibody MacBook Pro. What I wanted to do was use Carbon Copy Cloner to clone the old drive to the new MBP. I used CCC to clone the drive to the new one and repaired permissions on the internal drive and tried booting from it. No Luck. I figured this was stupid to do and I could just use migration assistant so I decided to reinstall Leopard on the unibody. Unfortunately when I attempt to boot from the DVD it doesn't go past a blank grey screen. I also tried holding down option to open the boot manager and select the DVD, when hit enter over the DVD it freezes. The interesting thing is that when I connect the old drive to the unibody using an enclosure I can boot from the external drive no problem. I tried using another computer to install leopard on the unibody over firewire and the installation went fine but when I start the unibody it doesn't go past a blank grey screen. I am also positive the hard drive isn't damaged or anything because when I go to the boot manager after leopard is installed the internal drive shows up but when I select it, it freezes. I have tried resetting the PRAM, NVRAM, repairing the disk (which is successful). When I try to boot into single user mode the computer freezes when loading the text. Another interesting thing is that when do boot from the external drive it goes through verbose mode every time and I never choose to do that. Right now I am attempting to clone drive using Super Duper to new drive and see what happens.

IMac :: Unable To Install Clean Snow Leopard / Instructions To Install On Internal Drive?

Dec 20, 2009

The internal hard drive on my early 2009 iMac is being replaced but I have to reinstall Snow Leopard myself.I did search in MRoogle and at Apple and cannot seem to find instructions on how to perform a clean Snow Leopard install on an iMac internal HD.

Can I do this? And if so how? Or do you think I should try and install Leopard on the existing Hd in the iMac? I still have these discs but have to get the SL applications install disc out of my drive (it's stuck and the iMac won't boot past the blue screen).

OS X :: Snow Leopard Installed From External Hard Drive Won't Boot?

Feb 16, 2010

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?

Mac Mini :: Will Not Boot From CD Or Hard Drive, Internal Or External

Jan 23, 2009

I have owned a Mac Mini for three years now (my friends convinced me to try the Apple way and this is my first Mac). The CD/DVD died just three weeks after warranty expired and Apple said (in essence) 'tough didn't buy AppleCare'.I have functioned without a CD/DVD drive since then, and everything was fine... until a week or two ago. We installed an update in iTunes, and everything started running S...L...O...W... So, we rebooted the computer! Instead of rebooting, it made the "bong!" sound and then a screen with an apple and a spinning wheel runs indefinitely. We let it run all night the first time and it stays on that screen for as long as you let it.

OS X V10.4 :: Unlock Directory Window Of Internal Boot Drive?

Jan 31, 2012

Whenever I restart Tiger, it closes all the directory windows.  I thought it should preserve all the window states in Tiger when you restart. 

If I resize the directory window in my internal drive, it does not preserve the new window size.  But if I resize an external disk directory window, it preserves the new size. 

I found out from Get Info that my internal drive is locked with read only permission only, but my external drive is unlocked with read+write permission. 

How do I change the permission so the window states can be preserved on my home drive?

Intel Mac :: 27" (2009) Won't Boot OSX From The Internal Drive?

Apr 14, 2012

Here's a fun problem. After installing Sophos anti-virus and starting a (VERY slow) full scan, a day or two later I found my iMac frozen at the screensaver. It was completely unresponsive so I did a hard reboot, at which point it got as far as starting to boot Lion (apple logo on screen, spinning indicator showing) before stalling indefinitely in that state with the indicator spinning.  

I restarted and booted from the recovery partition, launched disk utility, and discovered that the SMART status of the drive was "failing". The machine would still boot from the recovery partition and my boot camp partition, but I assumed that the disk failing was why the OSX partition wouldn't boot (the recovery partition worked, as did the windows 7 bootcamp partition). I replaced the factory-installed internal HDD with another of the same make, model, and capacity (Seagate 1TB), and performed a restore from the Time Machine backup on my Drobo.  

The result was the same as the original problem - it wouldn't boot, hung with the indicator spinning. Thinking that the Sophos scan was somehow responsible (in-progress when the last TM backup was made) I tried restoring to a backup a few days older, (to the best of my recall from BEFORE I downloaded Sophos) only to have the same result. 

Anyone have any ideas? I made a clean install of Lion (using the recovery partition on my old internal HDD, now connected externally via USB) to an external drive while I was waiting for the replacement hard disk to arrive, and it boots fine from that. I haven't tried a clean install to the internal HDD yet, as I'd obviously prefer to recover my installed apps as they were before, that being the point of a Time Machine backup, right?

Mac Mini :: 2011 - Boot Up On 2nd Internal Hard Drive?

May 16, 2012

I just picked up a Mac Mini today, after I lost all patience with my circa 2007 MacBook Pro when it stopped booting up this morning. I ordered more RAM and am planning to install the recently replaced hard drive from my MBP into my Mac Mini. I'm just wondering, will that drive just show up as another hard drive, similar to the way that external hard drives appear? And more importantly, the old hard drive has an older version of Snow Leopard installed, as well as a bunch of software, including my Adobe CS software. I've already jumped through hoops with Adobe to get my software reinstalled on my MBP a few months ago, and I don't feel like dealing with that again. So if the drive does show up as a separate device, can I just run my Adobe software from that drive? Or do I have to reboot but select that old hard drive at startup (if that's even an option) to run all software on it?

Mac Pro :: Multiple Hard Drives Boot Drive & Internal Raid

Jul 11, 2009

I just got a used mac pro quad. I plan to use it for video production- final cut pro, pics - aperture, and music production- protools. THe computer came with 3 - 10k rpm 160g hd's. Two of them are set up as a raid 0. I like the idea of having a faster drive as a boot drive, but 160 seems kind of small to me as the drive to run memory hungry apps and the operating system. Am I right? I could go to a 300g 10k rpm drive. I am also thinking about getting a bigger drive, say a 750g or 1 tb 7200 rpm. Should I use this as the boot drive or as a secondary storage drive?. If it's the boot drive should I add the other 160g 10k drive to the raid or keep it separate? I assume that neither way would be wrong, nor create a problem, but since I haven't put anything on it yet, I'm wondering what would be the most efficient way to manage my files and get the most out of my computer.

OS X :: Snow Leopard On MacBook - Installation Doesn't Finish

Jan 17, 2010

I just bought Snow Leopard today and I am trying to install it on my MacBook (with intel processor). I have inserted the dvd and tried to install it but there seems to be a problem as it is written: "Time remaining about 45 minutes" and this doesn't change. The dvd has been running for over 2 hours now and I don't know what to do nor what is going on? I understood installation with Snow Leopard should be faster. Is it normal that it takes so long to install the operating system (more than 2 hours)? It should just be an upgrade as I have Leopard already installed. I also have Windows Vista installed on a disk partition. Does that make any problem? It shouldn't as at the beginning of the installation I chose Macintosh HD.

OS X V10.6 Snow Leopard :: Best Way To Transfer To New Internal HDD?

Jun 17, 2012

I have Snow Leopard 10.6.8 on my Mac Pro and also backup using Time Machine. My main (startup) hard drive is close to failing-- before it does I want to transfer everything to a new internal drive. Seems to be there are several ways to do this:

1. Clone the original drive to the newer drive with 3rd party software (such as ChronoSync?)
2. Restore to the new HDD from Time Machine (which I believe requires me to clean install Snow Leopard on the new drive?)
3. Use Migration Assistant.

Which would be the best route?

MacBook Pro :: Can't Boot From Snow Leopard DVD?

Sep 5, 2010

I need your help diagnosing this early 2007 Macbook Pro running the latest version of Snow Leopard. It isn't mine, rather my sister's, so I don't know the full details of everything as I don't see her all the time. Last December, I swapped in my 160gb 5400RPM SATA drive from my late 2006 MBP into her MBP as I had just bought and installed a 500gb 7200RPM drive into my MBP. I installed a fresh copy of Snow Leopard onto her machine, patched it up, and sent her on her way.

A few weeks ago, she came to me saying she was having trouble booting into OS X and was just having trouble using her laptop in general. The hard drive wasn't making any erratic noises, so I figured the system install had corrupted itself. The problem was I wasn't able to boot to the Snow Leopard DVD. The DVD would show up at boot when holding down the Option key to show boot devices, but when clicked, it would show the Apple logo, then the "prohibitory" symbol and the fans would spin up on full blast, with no further progress.

Booting into Single User mode, I was able to run disk repair and after running it over a few times, I was told the drive was without errors, the laptop booted fine (minus the booting to Snow Leopard DVD) and I gave the MBP back to her.

Fast forward to today, she's having issues booting in to OS X again. It'll show the Apple boot logo, but the small spinning circle will freeze, and the whole laptop will come to a halt. I still can't boot to the DVD either, with the same symptoms as above. I'm sure I can boot into Single User mode, run Disk Repair, and probably be good, but I want to attack this issue at the source.

Is the hard drive I've got in her MBP going bad (I can't hear any of the erratic noises you hear when you know a drive is going bad)? What else could it be? What about the inability to boot to the Snow Leopard DVD? What is the problem and how can I fix it? Thanks, and sorry for the long winded post.

MacBook Pro :: Snow Leopard Boot Times?

Aug 28, 2009

I was planning to get Snowey and a SSD at the same time, but the latter had to wait. So far, I�m seeing at least a ten seconds improvement in boot time with Snow Leopard:

17" Macbook pro unibody 2.93 Ghz, 4 GB ram 7200rpm HD

before SL: boot up from 39 to 55 seconds

after SL: boot up time from 30 to 39 seconds

Ok, so there is no interest in this topic.

For me boot time is a rather important criterium.

And I think the fact that SL reduce this with almost 10 seconds is AMAZING.

OS X :: MacBook Won't Boot After Installing Snow Leopard

Aug 28, 2009

It just hangs at the spinning pinwheel. I shut the machine off and booted it into Verbose-mode (Command-V) and it stops at "Initializing Power Manager" or something very early on. I pulled the battery and unplugged the machine, am letting it cool off (not that there's a point) -- it's one of the original MacBooks that had that "shutoff" problem with the wire that'd melt and short to the heatsink but mine never had the issue because I wasn't using it very often at the time. Any ideas? The drive does show up when I hold down Option.

MacBook :: Cannot Boot After Snow Leopard Installation

Nov 27, 2009

My leopard installation was giving me a lot of headache so I thought of doing a clean install. Now that Snow Leopard had been out for quite sometime and many issues solved; I thought of installing it instead of Leopard. All I did was follow the instructions to install Snow Leopard [the only option with Snow Leopard was that it did an "Archive and Install" kind of thing by default]. It did take a lot of time [1 hour?] and I was finally taken to my desktop. I looked to check if everything was okay. Though there was nothing spectacular about Snow Leopard. I shut the computer down. Today morning I get this and I can't boot.
