Mac will not boot after Snow Leopard install

I recently had a HD crash. Replaced the HD and installed Snow Leopard from a image file on an external HD. Install went great. I copied over data files and things seems just fine. My first reboot after the install and the Mini won't boot. I am stuck with the Apple Logo and a spinning wheel. I ran disk utility and the new HD checks out fine. When I boot with the external HD, it still sees my Mini HD. I tried restarting with Command/Option/P/R but that didn't do anything. Any advice?

I'm in a slightly similar spot- no crashes, but-- What I want to hopefully do is run my Tiger ppc apps (3) for CAD on my New- 5 weeks old) Lion Factory Installed machine. The ( November) First Aid Issue of Mac Life mentions a way
way to get external boots, UNLESS they are the Factory installed ( Lions). In the meantime----

OS will not boot after Snow Leopard Upgrade

I have a MacPro (Intel). I just upgraded to Snow Leopard and everything appeared fine. However, after restarting my computer the OS will not load. A circle with a hash through it replaces the Apple logo and the apple's spinning wheel continues but all drive activity. I have tried to run the install again by forcing the computer to open the dvd drive then booting for the OS DVD but this has not worked. Has anyone experienced this and successfully resolved?

You have a five year old computer, so a failing hard drive at this point is not so strange. You have a couple of options you can try. Start with this one, but if it does not work you will have to erase the hard drive. I hope you have a backup of all your files.
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

Macbook pro will not boot after snow leopard upgrade

My GF has had a macbook pro since mid 2008. It's been running like a champ since I've known her for the past 3 years with no issues. It has/had OSX 10.5.8 installed. We tried to consolidate all our pictures from all our apple devices and realized she didn't have an icloud on the old 10.5.8 OSX. So I called apple and they told me to order and install the snow leopard OSX 10.6 first and then upgrade to lion etc after that, Well we got the disk yesterday popped it in to install and it's been a disaster.... the computer shutdown for what looked like a normal restart during the installation process and never booted back up. Attempts to manually reboot leave us locked on a grey apple logo screen with spinning gear indefinately whith the Snow Leopard disk installed during boot up. With the disk removed I get the flashing file folder with a question mark. I called apple support we tried all the PRAM and SMC resets and then decided that we should go to the Genius Bar once all those failed. After an hour and a half drive to the nearest genius bar we were told that the we suddenly had a hardware issue which just happened to coincide with the new OS installation.... I'm not buying it and am looking for some help. The macbook was running like a champ until we inserted a disk recommended by apple... Any takers?

Aperture will not work after snow leopard instalation,

Hi,
I have avoided upgrading to Snow Leopard but my children bought me the upgrade for Christmas as they want me to use Face Time. So I did, now aperture will not open and it says contact the originators of the program. I am a pro photographer and all my current work is on Aperture and I have a wedding in two days time and so this is somewhat disturbing as all my post production in done in Aperture. Can anyone help me I have done all the software upgrades etc.....

Are your images files managed in the Aperture Library, or Referenced? Do you have an external disk drive in the configuration, and if so, is it formatted as Mac OS Extended?
If you hold down the Option key while clicking on the Aperture Icon in the Dock, do you get the dialogue that allows choosing between different Aperture Libraries, or even creating a New Library?

Safari will not work after Snow Leopard Install

Safari does not work. It opens briefly, then closes. I get a message to "click reopen to open application again," but the same thing happens. Please advise.

Janice,
Quit Safari if it's open.
Locate this file. com.apple.safari.plist
/Users/YourName/Library/Preferences. Drag that file from the Preferences folder to the Desktop.
Launch Safari. If it launches without crashing, then that .plist file is corrupted. Drag it to the Trash, empty the Trash and restart your Mac.
If Safari still crashes...
Go to ~/Library/Caches/Safari and delete all the sub-folders within that one.
Go to /Users/YourName/Library/Safari and delete Home/Library/Safari and delete any of these files you have there:
Downloads.plist
History.plist
LastSession.plist

My iMac will not boot through Snow Leopard but will boot through Windows OS

My 2010 iMac will not boot in Snow Leopard, only Windows. Have tried reinstalling Snow leopard a few times and works only for a couple of minutes before freezing and doesnt reboot. Windows works perfect. Snow leopard just doesnt want to boot up past the Apple Logo. It was working fine one day and the next day it froze up and was able to reboot back into Snow Leopard but kept freezing. Now it doesnt load at all into Mac OS.

Possible scenarios:
1: The 10.6.3 SL retail disk is bad, it happens.
2: Your not using the 10.6.3 SL retail disk but one from another machine which doesn't have the drivers for that machine.
3: Your optical drive is funky or some other hardware issues.
4: Your trying to install 10.6 onto a PowerPC based Mac, no can do.
5: Your not using a wired keyboard for boot key commands, have some other hardware conflicts.
Possible solutions.
1: Copy the SL 10.6.3 disk using Disk Utility to another DVD, the error checking may resolve the original disk's issue.
http://www.brokenhomeboy.co.uk/pierow/blog/2011/10/make-a-bootable-backup-snow-l eopard-install-disc/
2: Make a SL bootable USB
http://www.maciverse.com/install-os-x-snow-leopard-from-usb-flash-drive.html
3: Call Apple for a new 10.6.3 disk (and make copies for backup before Apple discontinues selling it)
If your upgrading to 10.6 to get to 10.6.8 to upgrade to 10.7, be warned of this:
1: Your 10.5 software will not work in 10.7, no more Rosetta or PPC based code.
2: Your hardware will not qualify if it's a 32 bit Intel Core Duo, also you may experience slowdowns in performance over 10.6 (10.6 is the fastest OS X version for Intel Macs) in older Intel hardware (I suggest Early 2011 Mac's and later only for Lion)
3: Mountain Lion 10.8 is reportingly coming out this summer and will not run on a lot of older Intel based Mac's because of heftier graphics requirements.
4: 10.6 has the widest range of current avaialble software and drivers for third party hardware.
My advice, stick with 10.6.8 and stay there, buy a new Mountain Lion machine after this summer. Skip Lion completely.

HP Photosmart C6300 printer/scanner not working after Snow Leopard install

HP Photosmart C6300 printer/scanner not working after Snow Leopard install
Reinstalling etc does not work - does anyone else have the same problem or a clue as to how to fix this?

Keith,
I got a C6280 and the scanner does not work anymore. I am for 6 days in contact with HP. The last printer driver install form the apple web site does not open the image of HewlettPackardPrinterDrivers.dmg because of an invalid checksum. The skipping of the validation gives and error in the install.

I have a MacBook Pro 15" and my warranty just ran out! I partitioned my harddrive into two partitions, one with Snow Leopard and the other with microsoft.This morning I turned on my Macbook Pro and it will not boot into Snow Leopard.

Good Morning,
I have a MacBook Pro 15" and my warranty just ran out! I partitioned my harddrive into two partitions, one with Snow Leopard and the other with microsoft.This morning I turned on my Macbook Pro and it will not boot into Snow Leopard. I shut it off took out the battery, reinstalled the battery. Then I put in the Snow Leopard CD and booted up to disk utility and The Snow Leopard partion would not show up?? I do see the microsoft partion.
I also rebooted holding down the shift key and still no Snow Leopard
Could you please tell me what I can do, what keys do I press on restart any advice to get Snow leopard back.
thank you.

Have you restarted holding down the Opt key? That procedure should give you a gray screen with all of the partitions that exist. Then select the SL partition for boot. Also go to System Preferences and Startup Disk, unlock the lock and select the SL partition as the default boot partition, then relock.

HT4623 iPhone 4s will not boot after trying to install ios7 beta 4. Stops at apple logo with progress line under it. how can I reset it or get it back up to do a restore then try the iOS 7 beta 4 install again. Issue was probably caused by disconnection

Obviously since you have iOS 7 you're a developer. As a developer, you signed a NDA with Apple not to discuss the iOS on a public forum. Please log in to the Developer Forum using your credentials and ask for help there, lest you risk having your credentials terminated.
Thanks, and best of luck to you.

Mac Pro will not boot with Snow Leopard - need help!

I have had a lot of issues with Snow Leopard since I upgraded from 10.5.8. Most of my problems started after installing Office 2007. I finally wiped the hard drive and reinstalled everything. No problems until last week. Start up was taking longer and had to reboot a couple of times because of grey screen. So I would just put computer to sleep. Yesterday the computer was frozen on screen saver with scrambled rows of pixels on screen two and the main monitor had a frozen image.
I initially pulled all peripherals out and pulled the power plug for 5 minutes. I have left the peripherals out and pulled the second monitor as well. I tried pulling the power plug during a few more starts but nothing gets me to a complete start up screen.
I have tried resetting PRAM and VRAM and tried a safe boot. I tried booting from Snow Leopard and my Leopard disk stayed on either a blue or gray screen with spinning beach ball (on gray screen).
Put original install disk in and booted from using D to check the hardware. Good news is that the hardware test was OK. I did the extended test.
All different kind of start up problems.
- Some start with start up sound goes to Apple logo to blue screen to grey screen with beachball
- Some start ups with no initial sound then Apple logo to blue screen to grey screen with no cursor or beachball
- Some start ups with no sound to gray screen to blue screen to grey screen.
I have no problem wiping the HD1 again but I can't even get the OS disk to be recognized with holding the C key during start up. This last time it went to a blue screen (holding the C key) and a cursor.
I don't know what else to do - Please help!!!

There are lists (MacIntouch and MacFixit) of hardware / software support issues with 10.6. Accelerateyourmac is another place to watch.
There were some really long threads back in Sept about printer driver support.
The 7300 firmware was more about Windows support; those cards are failing and dropping like flies (how DO they know 3 yrs has expired anyway?) and they don't support SL features like OpenCL etc so I'd invest in ATI 4870, best graphic card and works in all models Mac Pro.
Lots and lots of bootable clones for backup. Never need to wipe and install again.

IMAC 21.5 " allinone will not boot after OS re-installed

Had to erase HD and re-install Snow Leopard from installation disc. It completed OK but sys will not boot, tone sounds and Apple logo comes up and 'wheel' is spinning, but that's it. Waited for over half hour before shutting down. Thanks for any help anyone can provide.

Try a safe boot by holding the Shift key down between the startup tone and logo.
If succesful, go to System Preferences > Startup disk > select your HD and restart.

TS3479 quick time not working after snow leopard install?

Made video's on my iphone and loaded them to my imac. Video did not work in iphoto. No Quick time pop up. what happened? Snow leopard install.

You need to re-install iPhoto because it's missing bits of itself:
Library not loaded...
Reason: no suitable image found.
Looking at the missing files it's possible that it's missing from the OS. But start with re-installing iPhoto, and if that fails you'll ned to re-install the OS.
To re-install iPhoto
1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)
2. Go to HD/Library/Receipts and remove any pkg file there with iPhoto in the name
3. Re-install.
If you purchased an iLife Disk, then iPhoto is on it.
If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. Insert the first one and opt to ‘Install Bundled Applications Only...’

IMac will not boot from Snow Leopard DVD or original Leopard disc!

Hey,
I am going mad! I am trying to update my iMac (with original Leopard installed) to Snow Leopard. Here is what I have tried:
Using the Snow Leopard DVD:
- A standard install: the disc ejects after about 15 minutes.
- Put another working DVD in and verified it in Disk Utility, all ok.
- Verified the internal hard drive in Disk Utility, all ok.
- Verfied the SL DVD, all ok.
- Decided to try a clean install, so backed up everything.
- Tried to boot from SL DVD by using the Utilities option, it ejects the disc at restart.
- Tried to force it to boot to the DVD by restarting and holding the C key, it ejects.
- Restart holding the Option key, it ejects.
- Restart holding the Ctrl, Alt and Option keys, ejects.
- Everytime it ejects and starts up normally.
- So I cleaned the disc, updated all the firmware, reset the NVRAM/PRAM via holding keys when restarting, and repaired disc permissions.
- Tried to force it to boot again, ejects.
- Tried to put the disc back in straight after it ejects with all the steps, still starts up normally.
- Changed the start up disc in System Preferences to the SL DVD, restart, it ejects.
By now I am readying the noose...
- Dug out the original Leopard installation CDs.
- Repeated all the forced boot restarts (C key, Option key, Ctrl, Alt, Option keys), same story.
- Repeated changing the start up disc in System Prefs, same story again.
- Call Apple Support, they told me to try everything I have tried and that the DVD drive is dodgy, well it works with everyhting else! Burning and reading! I really don't want to have to go to an Apple Store- it's miles away (a costly journey) and I just do not have the time for all of this.
RAWR! Does anyone know what to do? Please? S.O.S.?

Possible scenarios:
1: The 10.6.3 SL retail disk is bad, it happens.
2: Your not using the 10.6.3 SL retail disk but one from another machine which doesn't have the drivers for that machine.

Time Machine will not backup after Snow Leopard.

Pertinent information:
Macbook Pro pre-aluminum body
Time Machine backing up over network to a ppc mini with 500 gb external drive.
This worked fine with Leopard for over a year. I installed Snow Leopard last week and this is the first time I got a chance to try a Time Machine backup. Doesn't see to want to backup no matter what I do.
I tried:
- Renaming the sparsebundle
- Disconnecting/reconnecting the external drive.
- Re-selecting disk in Time Machine config and nothing works.
- Even ran Verify Disk and Repair Disk on the external drive. Found a header error, but Disk Utility said it was minor and fixed it.
It seems that Time Machine isn't even trying to figure out what needs to be backed up. Here is the log. Below this snippet of the log I will post some of the other things I see...

Can't really find any info on any of these errors. I search through discussions and it doesn't seem that anybody is having the same problems as I'm having, seems they are having different problems.
Thanks in advance for any kind of information you can provide on this problem.

Unfortunately a "full reset" didn't do it. The log looks almost exactly the same...

Still confused over the "does not support TM Lock Stealing" and "does not support Server Reply Cache"? Are those the possible causes? I'm really at a loss cause like I said in my reply before, Time Machine just always worked.

AE CS4 Will not open after Snow Leopard Upgrade

Ok, i posted this earlier but I don't think I was clear enough to get an answer. I recently did a clean install of Snow Leopard and a fresh install of my Production Studio CS4. Upon getting it all installed, I realized that After Effects will NOT open at all. It just bounces on the Dock a few times and then stops. Then after that, when you click on it, it bounces once, then stops. Every other program works great, only after effects is not working. Why is this? Is there something I need to do? I reeinstalled just the AE and downloaded the newest update, still, the same thing. I would appreciate any suggestions to get it running.

I experienced this when upgrading to Snow Leopard myself.
After Effects is one of many, many applications which require Rosetta to be installed. In Snow Leopard, Rosetta is an optional install on the disk. So just make sure you install it.
Now, the thing also is that once Rosetta is installed, the OS still seems to have AE flagged as an app which requires a missing component to launch. This was fixed after a couple of restarts, in my case.
