Software installer update caused macbook pro/snow leopard to not start

I ran the recent software installer update; since then my macbook pro--running 10.6.8--won't get past the blue screen. i tried verifying/repairing permissions and even reinstalling from the disk but it tells me simply that reinstalling from the disk cannot be done.
The only other relevant information I can think to share is the fact that my harddrive is partitioned with bootcamp, running Win7 64-bit.
Thanks in advance for any and all assistance.

Had the same problem with my Early 2006 Core Duo iMac and Starting up in Safe Mode ended up being the fix.
see > Mac OS X: Starting up in Safe Mode
1. Be sure your Mac is shut down.
2. Press the power button.
3. Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
4. Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
In this case starting up into Safe Mode will take a lot longer than normal, so be patient and let it finish uninterrupted.
Likewise after Safe Mode, starting up into normal mode is also going to take a lot longer than normal, so once again be patient and let it finish uninterrupted.

Macbook pro (snow leopard) will not boot after software update

I helped my mom buy a Macbook Pro for herself for Christmas. Today, I connected it to her old eMac and used the migration assistant to transfer files over. It was unable to estimate migration time on the only user (after 45 minutes) so I didn't migrate the user. Then I tried to pair her macbook to her new bluetooth keyboard, but no magic happened, so I tried to use the bluetooth setup assistant, which crashed. So I ran a software update, hoping that this would fix whatever the bluetooth problem is. Despite having updated on the 23rd, there were 4 updates. None seemed applicable but I installed them anyway. Now the computer won't boot at all.
Software update said that I had to restart for the updates to take effect, so I restarted. The harddrive went whirrrrrr and the grey screen with the apple logo and the spinning circle displayed. Then the harddrive stopped going whirrrr and 10 minutes later, I started looking on the support site for what to do. I found this:
http://discussions.apple.com/thread.jspa?messageID=10564149&#10564149
Per the instructions in the last post, I fscked the drive (although -f, in accordance with the fsck help). This found no problems. The next suggestion was to boot from the OSX install disk. Only one problem-- there was a disk in the disk drive when the problem occurred and the disk eject button apparently only works while in the gui. I can't install from disk if I can't get the existing disk out of the drive.
So, any other ideas on what I can do to get this machine to boot?

Hi Jen:
Since it's new, you're entitled to 90 days of phone support (3 years if you buy AppleCare). It sounds to me like you may have some hardware issue(s) going on - you should not have the sorts of issues you're having with a new Mac. Apple will probably be much better and faster about getting you fixed than this board may be able to if that is the case.

My MacBook Pro Snow Leopard will not shut down.

When I try to shut down my MacBook Pro it goes as far as the spinning wheel on the blue screen and will not complete the shutdown. I have to hold the power button to shut down completely.
Both disk and permission repair does not solve the problem.
Help please.

I had the exact same problem, the only way for me to fix it is to delete everything off your mac, or backup your data and reinstall the OS, but just reinstalling the OS won't fix it, back up your data (if you want to keep it) and then erase everything off your mac then put your data back in. Hope it helps.

Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

MacBook Pro (snow leopard) 2006 will not restart. Getting blank screen with folder (?)

MacBook Pro (snow leopard) 2006 has begun to turn off attached Cinema Display over the last two days. Comes back on on restart. This morning, the MacBook screen also went blank white on restart. Tried to use Snow Leopard CD to restart but it was ejected and folder with ? is only thing that displays. Will not restart. Have replaced hard drive 6 months ago. Help! What's wrong? I need this computer for work.

No. That has no advantage for you.
leave the internal HD alone and purchase an external HD that I can clone and use as boot drive in case of emergency?
Yes. I use Carbon Copy Cloner to make a boot drive and as a backup (in addition to Time Machine). CCC allows one to make incremental changes as well as creating a copy of the recovery partition. This means that if run on a proper schedule, you data will; be well protected and the MBP can be in operation very quickly if the internal HDD should fail.
A clone should be a 2.5", 9 mm thick SATA HDD so that it will fit inside the MBP. It can be powered from the USB port thus not requiring an AC outlet. In my collection of HDDs, I favor HGST and Seagate products. I principally use OWC enclosures that allow for USB, Firewire and eSATA connections. These are expensive but one can use a more modest one as well of one can tolerate longer data transfer times.
Here is a link showing some available SATA HDDs that will complement your MBP:

You can look for enclosures on the same web site.

Macbook Pro Snow Leopard; WiFi keeps dropping, no IP Address

Macbook Pro Snow Leopard; WiFi keeps dropping. Issue is Macbook is not getting an IP address from the wireless routers DHCP Server. Tried all options in the forums. Reboot, changing security, PRAM reset .. nothing. Problem keeps happening. No issues on XP laptops and Nokia phones.
Even the iPhone, iPod and iPad seems to be fine. It is just the dang gam it Macbook pro and it is driving me crazy.
All fixes tried, changing wireless mode, security, PRAM ... only thing left is to rebuild the mac which i was hoping I can avoid somehow.
Any ideas to fix this would be great!

Well, you can try easing the shift key up with something thin but flexible (credit card sort of thing) but if the contacts below are stuck you may need to get it seen to by an authorised repairer.
If you can borrow a keyboard (a PC one will probably work as long as the password is alpha-numeric with no special characters) you can at least get in to backup your HD before going for repair.

Printer says "sending data..." and doesn't print (photosmart c440 & macbook pro snow leopard)

Hi, my photosmart C440 printer suddenly stopped working and wont print. The message says "Sending data..." forever but never prints. The printer is on but doesn't respond to what my computer says. I have a macbook pro snow leopard OS. This has never happened before, I didn't make any changes to the system. When the problem first appeared, I reinstalled the driver and was able to print once, then it stopped working. Then I installed snow leopard and it stil doesn't work.
Thank you!
This question was solved.
View Solution.

Let's reset the printing system:
- Sys Prefs, Print & Fax
- Right (control) click in the rectangle listing your printers and select Reset Printing System.
WARNING - this will delete ALL of your printers!
- Select the plus sign to re-add it. Look for the printer, select it and wait until the "Add" button becomes available. Click it.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

I have a 2007 Macbook, so it's probably a lot older than your Macbook Pro, but it sounds like what happened to me, except that mine hadn't travelled anywhere. I pulled out the ram and blew out some dust, popped them back in, and wha-la! it turned back on and worked better than ever! Or otherwise you've got a dud/old/warped/fried battery, which is also what happened to my laptop - it got so bad it did what your laptop is doing. Ordered a new battery online and all good since then. Or otherwise, like the previous post asked, 'is it plugged in?'

Mid 10 Macbook Pro Snow Leopard to Mountain Lion, worth it?

hello. now that i see many of the features of mountain lion won't work on a mid 10 macbook pro, has anyone with the same system upgraded? was it worth it? how did it go? i have the 2.4ghz intel core 2 duo and 4gb 1067 mhz ddr3 by the way. thanks for any help.

yes you will still be able to use all your files programs etc.
Actually, that is not correct! Just because an app is compatible with Snow Leopard does not mean it will work with Lion or Mountain Lion. As stevenfrombrownsburg points out, all PowerPC apps, for example, will not work in Lion or ML. However, beyond that, there may be many other apps that are not compatible for some other reason. You'd be wise to verify that all the apps you depend on are compatible before upgrading. The following site will help:
http://roaringapps.com/apps:table
If some of your apps are not compatible with ML, you should update or upgrade them first, before upgrading to ML.

I have just update my MacBook to Snow Leopard 10.6.3. Unfortunately I can not now connect to the internet. I have a time capsule that is connected to a router. This is working with other devices but if I try to connect with the MB everything stops?

I have updated my MB to Snow Leopard 10.6.3 - I know this means I am a little behind the times but the problems I am now having seem to justify my reluctance. Now am unable to connect to the internet! I use a time capsule connected via a router. Everything is still OK with every other device (PC, I phone, Ipod) in the house so I know the "Network" is still enabled and there is no problem with the ISP. Strangley whenever I boot up the MB it appears to freeze the network such that the other devices also will then not access the internet. To regain access I have to turn off the MB and reset the router. Any help gratefully recieved as I have tried some of the ideas i have found in the internet but nothing is working. Thanks.

That's odd.
Try this: Unplug your Time Capsule and your router. On your MBP, click the Wi-Fi icon and select "Open Network Preferences".
Click the lock icon to authenticate, then click the "gear" and select "set service order". Wherever AirPort (or Wi-Fi - I forget what Snow Leopard calls it) appears, drag it elsewhere in the list. Click OK, then Apply, then power up your router and TC.
If that doesn't result in any change, repeat the above but try making the service(s) you do not need "inactive".
The purpose of this is to reset or at least change your Network Preferences, which somehow got confused upon upgrading to SL.

MacBook Pro, late 2013 will not start up on battery.

Why won't my MacBook Pro (Retina, 13", late 2013) start up on battery, even though it's charged 100%? I can start it up with the power cord, then disconnect the cord and it runs fine and the battery doesn't seem to run down too quickly. I just downloaded OS X Yosemite 10.10.3 last night and this started today. Any help?

Try a SMC reset:

MacBook Pro & Snow Leopard Update: No-Entry Symbol

Hi Everyone,
I’ve run into some trouble as of last week involving my MacBook Pro. I feel as though this trouble may be a ressult of the 10.6.2 update, and was hoping you all could give me some advice on resolving it.
Shortly after updating to 10.6.2, I’ve been prompted with the “No Entry” symbol at startup. In other words, the Apple symbol comes up at startup, attempts to load then goes to the “No Entry” symbol.
The strange thing is, I am able to start up the computer in “Safe Mode” by holding down the shift key. This enable me to perform some of the trouble shooting steps below.
Here are some trouble shooting steps I’ve taken already:
- Start up in Single User Mode: I was unable to start up in this mode as the single user mode refuses to start up
- Rebuild the desktop: No effect
- Reblessed the hard drive: No effect
- Clear cache’s: I used the app called “Snow Leopard Cache Clear” with no effect
- PRAM/NVRAM: I reset these with no effect
- Disk Utility: Repair permissions and repair disk – no effect
- Startup/Login Items: Cleared all items, no effect
The strange thing is, I’ve experience this problem when I first did the update, then it went away, and now it’s back.
I don’t believe it can be a hardware problem because the computer starts-up fine.
I do feel as though it may be linked to my Airport Express or Extreme somehow though, as I am unable to access my Airport Express & Extreme with my iPhone after this issue began.
Any tips and suggestions would be greatly appreciated!
Thanks,
Travis

The strange thing is, I am able to start up the computer in “Safe Mode” by holding down the shift key.
That indicates that whatever is wrong with your system involves something that is disabled by Safe Mode. Here's a list of exactly what Safe Mode does:
http://support.apple.com/kb/HT1564?viewlocale=en_US
- Rebuild the desktop: No effect
How exactly did you do that? This is a troubleshooting step that applies only to Mac OS 9 and earlier, and is not relevant to Mac OS X.
- Reblessed the hard drive: No effect
This, again, is more relevant to Mac OS 9 and earlier. Although possible on a Mac OS X system, I've never heard of reblessing as a troubleshooting tip in Mac OS X.
- Clear cache’s: I used the app called “Snow Leopard Cache Clear” with no effect
Safe boot clears any relevant caches for you. Cache clearing beyond that is not generally necessary, despite what the makers of the various cache cleaners would have you believe.
The other things you did were good, but you didn't mention whether Disk Utility found any problems when you repaired the disk. If problems were found and repaired, that doesn't mean that any file corruption that happened as a result of those problems has gone away.
If I had to guess, I'd say that probably one or more of the optional system kext files is damaged, which would explain why Safe Mode works. That's purely a guess, though, and could easily be wrong. Unfortunately, I think that the fastest solution is to erase your hard drive and reinstall the system and all applications from scratch. There may be other troubleshooting steps that might help, but it could take days of testing and back-and-forth here to find the right ones.
