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.

My hard drive recently crashed. I just bought a new one and installed it myself. Now it's simply a matter of reinstalling the operating system, which is where I'm having trouble. I insert the Snow Leopard Install DVD into the drive. I power on the computer and hold 'C' (I've tried Option too) to boot from the disc, but it doesn't work. It spits out the disc after a few seconds, whether I hold 'C' or not, and then it gives me a folder icon with a question mark in it in the center of the screen, the same thing it showed when my hard drive first crashed.

I have a tower Mac Pro with Snow Leopard running on it.Unfortunately one of the software that I use doesn't have yet a Snow Leopard update. So I am thinking maybe I can install older version of Leopard on one of the internal drives (i have 3 additional internal drives), so I can boot my computer from either Leopard or Snow Leopard, depending on needs (i don't want to get rid of Snow Leopard).
I never installed OS X system before, so I am a bit scared.The internal drive is ready, I have the old Leopard on disks, what are the next steps to take?

with my Leopard installation i have a problem where it fails to boot up likely due to a previous unexpected power cut.
From googling the issue it seems like the only solution anyone has had to the same problem is to re-install.
However I've lost my Leopard system discs.
I booted into my Bootcamp Windows installation and installed the latest drivers from the Snow Leopard disc which i recently purchased (and came today)
This gave me the option to read files (and presumably copy) from the mac partition but no delete function.
I have two problems here:
1. I only have 2.61GB free on the mac partition, Snow Leopard requires at least 5GB. Since I can't boot into OS X and Windows can't write to the partition i can't delete any files.
2. My mac won't boot the Snow Leopard DVD for installation. I hold C while booting and it has no effect. It does however run the Hardware test if i hold D while booting.
I have an external drive i could probaly make enough room on to back up my entire osx partition for a totally clean re-install.
However this requires some sort of access to the drive/write capabilities. Maybe something like bootable linux?
And any idea why my disc won't boot? (even if i had enough space for a install...that would be a bit pointless if i can't get the disc to boot)

I tried to install snow leopard on my 3 mos. old macbook pro and received a failure message with the invalid node structure, rebuilding catalog B-tree message.
Not sure what to do, I tried booting up from the leopard install disk and it took about 15 minutes to boot up and everything is wonky, doesn't work right.

I have recently installed new RAM and an SSD in my late 2009 MacBook Pro, running OS X 10.6.8, and it now frequently hangs when I try to start it up. Here are details:
In recent weeks I noticed signs that seemed to point to a failing hard drive. I took the machine to a Genius Bar. The genius tried Disk Utility and a quick diagnostic and could not reproduce an error, but he noted many, many I/O errors recorded in a log file.
He said I probably had a failing disk, but it might be a cable issue. He gave me two options: leave the machine with Apple overnight to run diagnostics and perhaps repair if the problem was confirmed, or just take a chance and replace the drive myself, for less money and less downtime.
I went to a local computer store, and the salesman there noted that I was using relatively little disk space. He suggested that I swap my failing 160 G disk for a smaller, 120G solid-state drive, which happened to be on sale. I agreed and also bought some new RAM.
I installed the drive and RAM, partitioned the disk (with HFS journaling), and restored my files with Time Machine. For that day and the next, everything worked perfectly.
The second day after the installation, the system hung while starting up. The Apple logo appeared, the gray spinner appeared, and it just spun. I tried resetting PRAM. I tried safe restart. I started up from the install disk and ran Disk Utility: no problems found. I repaired permissions. I took out the new RAM and put back the old. In some cases after trying these steps, the system booted fine — once. In others, it would not boot the first time, but would boot on the second or third attempt. I reinstalled OS X and updated software. The problem persisted. I installed some freeware to enable trimming the new disk. No better.
I have booted many times in verbose mode. During the unsuccessful boots, there is usually a message "Bug: launchctl.c: 3557 (23930):6 ioctl(S6, SIO CAIFADOR_IN6, &ifra6) ! = -1". The next line is the command "fsck_hfs", and the machine hangs. Eventually it sometimes spits out "launchctl: please convert the following to launchd: /etc/mach_init.d/dashboardadvisory.plist". If I let it go for a long time, I sometimes come back to find a long string of I/O error messages, to the effect that media was expect to be there but wasn’t. I think every time I have gotten the launchctl message, it has booted successfully on the next try.
During the successful boots in verbose mode, everything happens so quickly that it is hard to say what is going on, but I don’t think it is running fsck_hfs. If it boots successfully and I give it a heavy I/O task, like doing a virus scan, everything works fine. If I run Disk Utility off the installation disk, it says the disk appears to be OK.
I started the machine in single user mode and ran fsck manually. It gave me reports similar to running Disk Utility, and told me the disk appeared to be OK. It then gave me the prompt for a new command. I typed "exit". It responded "logout". And hung.
One last thing: I just tried a couple of times to restart with the Apple Hardware test. Despite holding down the D key, the test failed to load, and after a long pause, the machine attempted a normal start-up.

I cannot find Boot Camp 3.0 on my Mac. I just upgraded to SL and it seems like it disappeared. A search in Spotlight returned nothing.

My wife's Macbook (2.0 Intel Core Duo) is not recognizing the Snow Leopard disc, and I'm not sure why. I initially thought that even though Apple is saying that all Intel's are compatible with SL, they focus on the Core 2 Duo's and since her computer is technically a single core, it wouldn't work. Everything I have read has stated that SL will just run in 32 bit mode with Core Duo's - so I'm pretty confused. As for it being a bad disc, it's recognized immediately in my MBP...

I'm trying to install Mac OS X Snow Leopard on to my macbook but I keep getting this error.
"mac os x installation couldn't be completed" I get this message usually within 5 minutes of installation.
My macbook specs are...
Mac OS X Version 10.5.8, 2.16 GHz Intel Core 2 Duo, 1 GB 667 Mhz DDR2 SDRAM
I've already tried repairing the disks. (I repaired my leopard with the snow leopard CD because I couldn't find the leopard CD.
I heard it was fine to do.) I would have tried to verify and repair the partition but the buttons seemed to be grayed out for some reason.
Here is the error log...

Will it install like the OS does on the iPhone, as in the existing data isn't put in a new folder? What exactly happens when you install a new OSX?

My MacBook Pro will not go to sleep after installing Snow Leopard. It WILL go to sleep if I close the lid; however, if I have it sit open for 15 minutes, it won't go to sleep. It attempts to sleep, but instead the screen will just go black for less than a second. It's just like a flash of black, and then the screen goes back to normal. It simply won't sleep.

i got my first Mac today and it didn't come with snow leopard installed but it did come with a snow leopard disc. the problem is whenever i try to upgrade, i insert the disc, it stay's in for about 30 seconds making weird noises, and then it spits the disc back out. i'm very new to mac, today is my first time ever using one so i really don't know what to do so i came here. i have a 13 inch MacBook Pro running on OS 10.5.8. also, i installed iWork perfectly fine so i'm guessing it has to do with the disc.

I'm trying to install OS X on an Intel X25-M SSD. I'm at the point where it asks to select the disk where you want to install Mac OS X but no disks are showing as available. I can see that the computer recognizes the Intel SSD in Disk Utility but it says it's not formatted. Is that the issue?

My Mac book has an Intel 2.2GHz processor, 4GB of memory and 7.1 GB of free space on the hard drive. It comes up with a screen just saying it cannot be installed on this computer.

I want to install a SSD into my MacBook Pro (mid-2010). So, after I install the new SSD, I need to reinstall my OS (Snow Leopard). But the internal DVD player is broken. I have an external DVD player, but I am afraid the Mac will not recognize it because when I plug the external DVD player to the mac with USB cable, there will be no operating system on the mac. Am I just worried too much? Can I just install OS x from an external DVD player?

Alright first of all, Hello to you all, I've been reading this forum for a couple of month even though this is my first intervention and i need a tip. Alright my situation is the following: I have:
-Macbook Pro Unibody
-Macbook C2D
-Snow leopard Disc x2
-Snow leopard image I cloned to a hard drive partition.
The situation is I have bought two licenses for Snow leopard because i have two macs. The macbook pro is the computer i use everyday and is fully functional. The macbook however took a big drop about a year ago and the display was totally broke along with the DVD and the hard drive. I retrieved an old HDD i had with leopard installed and put it in the macbook along with an external display and i now use this computer as a media center. The problem is i want to install snow leopard on it. The DVD drive is broken hence the reason i made a disc image and i wanted to install from the disc image. SO i restart the macbook with the alt key and as expected, the image from the usb drive is detected and i launch the install. The problem comes from the fact that when the installation starts, the external display is set as secondary display and i cant control the installation which is displayed wont eh broken display. Is there a way to remotely install SL or to set the external display as only display at boot through holding a bunch of keys?

I would like to install Snow Leopard on my Macbook Air Rev A as I have work to do that requires 10.6.x - however I didn't buy the Superdrive so need to do this as a remote install.
I have a PC with a DVD drive and can install the software; I also have the USB ethernet dongle and assume this will be better to use than over Wifi
Has anyone got any hints about doing this? I'm slightly nervous about installing an OS upgrade over a network for some reason..

After installing snow leopard I've had constant issues with mobileme, first with data conflicts, after I choose which data I think is correct (I usually guess) it then (sometimes after several minutes) constantly props me for a password. It's constantly saying this:
It says this WHILE LOGGED IN, I've logged out a million times and logged in, the password is correct. After I log out and try to log back in, it also gives me this error.

Since installing Snow Leopard, I have noticed that my Mac will wake randomly. It does not happen all the time, but it does a lot. I have tried to reset the PRAM and it did not help. The "Wake for network access" option in Energy Saver is unchecked. Any ideas?

I recently discovered after installing the new Snow Leopard OS that I did not have a bluetooth option under my system preferences. I own a mid 2008 Macbook Pro (pre-unibody, more info below) and I know that I've used it before. I recently took my computer in to be repaired by Apple because the keyboard and trackpad were inconsistently responsive, and to fix it they simply replaced the entire top panel (with the keyboard and trackpad). I have also checked under the system profiler and it says that there is no information available for my bluetooth...what exactly does this mean? Did they forget to reinstall it? or what?

I was about to install Snow Leopard to my Macbook white 2.0 ghz with combo drive which I bought in 2007. I have Leopard installed. Is there anything I should know before I begin? I have an external HD with 160 left. Should I move important files there first?

"it is possible to completely erase a hard drive and install Snow Leopard without a pre-existing operating system in place, enabling users to bypass the possible headaches of an upgrade and go with a clean install instead. Wired said many users upgrading from Tiger should probably consider backing up their files from Tiger and doing a clean install instead."
I don't have an external harddrive. What other backup options do I have?

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.
