If you lost your install CD's for an iMac7,1. Can you use Snow Leopard to reboot/install?

If you lost your install CD's for an iMac7,1. Can you use Snow Leopard to reboot/install?

Best answer; see AnaMusic above.
Will SL do? Yes, provided you use the SL retail disc. A grey disc from another Mac will not work.
A few considerations -
Be warned that printer drivers, and scanner drivers in particular will almost certainly need updating for SL. That could be a problem if the printer or scanner is more than a couple of years old.
Many third party applications (and some Apple ones) may need updates for SL (Adobe particularly), so check with the vendors for compatability before you upgrade.
You'll need Rosetta to run PPC apps like Appleworks and many MS Office or Adobe versions. Ensure you select it from the 'optional installations' when installing SL.
Note also that any bundled applications that came with your Tiger original discs (iLife in particular) are not included on retail OS versions.

Snow Leopard Freezes, Reboots, Crashes, Kernel Panics

I have a Unibody MacBook Pro 15 inch, late 2008. I got it with Leopard, and I had absolutely no problems at all with it until I stupidly upgraded to Snow Leopard in September 2009. Since then my computer crashes a lot. Here is a list of problems I've had so far, most of them on seemingly random occasions:
- Kernel Panics (happened around 2 times, both while rendering a video in Final Cut Pro)
- Complete system freeze where the screen freezes on the last thing displayed, the last sound played keeps looping (if I'm in the middle of a Skype conversation or listening to music, for example) and nothing will react (including mouse, caps lock, eject key, the system won't even sleep when I close the lid) requiring a hard reset by holding the power button (happened at least 3 times). This has sometimes happened when all I was doing is listening to music on iTunes, I wasn't even touching the computer, and all of a sudden I just hear the last half second of music looping forever.
- Complete freeze where the mouse would still move, but the system would reboot automatically after a few seconds (happened once or twice)
- Reboots without any warning (happened around twice)
Basically these are my major problems, and all of these have happened in 10.6.1 and 10.6.2, except the kernel panics which have not happened (so far) since I updated to 10.6.2.
I have tried repairing permissions, it didn't change any of the above behaviours.
This is what I noticed:
These problems happen regularly, around one or two times week.
_*The problems only seem to happen when I set my computer to use the dedicated graphics instead of the integrated graphics*_ via "System Preferences > Energy Saver > Higher Performance". If I set that setting to "Better Battery Life", then the problems don't seem to happen at all.
However, I use Photoshop and Final Cut Pro a lot, so I need to set the graphics to +Higher Performance+. Dedicated graphics is one of the reasons I bought this computer, so setting it to Better Battery Life isn't a solution for me.
As I've said before, I'm running OS X Snow Leopard 10.6.2, and my machine is a late 2008 Unibody MacBook Pro with 4GB RAM and processor of 2.53 GHz.
I have performed an upgrade to Snow Leopard from Leopard, as opposed to a clean install. Trying a clean install of either Leopard or Snow Leopard will be my last resort if nothing else works, however, I am asking you whether you can think of anything else to solve my problems without having to do a clean install, as it would require lots of work and it would be a big hassle for me.
Thank you very much.

I am having the EXACT same problem, however I have an iMac (24"display, 2.93GHz, 4GB ram.) I think I've narrowed it down to Quicktime, but can't figure out a solution. I have both Quicktime Pro (7.6.3) and the version that comes with snow leopard - Quicktime 10.0.
Here is a list of applications which have been running during a freeze, shutdown or restart.
-iDVD
-Quicktime 7.6.3
-iMovie
-Safari (only when playing video)
-Adobe soundbooth (one time only)
I've tried everything from permissions repair to a clean SL re-install to everything in between.
Any ideas out there??

My iMac 10.6.8 w/ snow leopard keeps FREEZING/CRASHING??

ok lets see if i can type this without my computer freezing.
SO. to begin, i have a iMac 10.6.8 which also has snow leopard. I have recently downloaded many things, that ended up not working so i deleted them. I dont know if thats whats been slowing it down (the downloads still being installed but deleted from trash?) but lately my computer has been very glitchy. I dont have apple care or whatever, so i cant call.
This morning there was a "software update" so i decided, whatever, i'll do it. When i did, i rebooted and now my computer is freezing like a mother.
It is VERY ANNOYING and i dont know how to fix it. It just freezes randomly to. I go on safari for a minute, freeze, then hold power button to reboot.
or i click on another thing, freeze, hold power to reboot.
pretty much everything sets it off. I need to know WHY!? i have had it for a long time and its never been this bad. Another thing that sets it off is runescape. i play it from time to time when im bored, and now it freezes every time. but runescape isnt the only thing that freezes it, it freezes on everything else to. its so frustrating!!!!!!!!
i dont know what to do!?
i have tried these:
-online downloads for mac cleanup
-restart and hold apple+S
-restart and hold apple+option+P+R
-software update
i dont know what else to do. is there something i can download to clean up un-used apps. or unistall items?
i just want to play my games and have my iMac run smoothley. if anyone can help thatd be awsome.
skype me: castrojake
i just want someone who has had this happen, and fixed to help me out.
its an iMac 20 inch Mid 2007
10.6.8 with snow leopard

Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
In the Memory tab, are there a lot of Pageouts?

Snow leopard keeps crashing...help!

I installed snow leopard 10.6.3 and now I am having MAJOR problems. Sometimes I can get as far as the apple download and sometimes my system locks up as soon as it starts. This morning the computer would start, then restart, then start and restart all by itself. I have a 17" MacBook pro purchased several years ago ( maybe 4 or 5?) at this point I don't know what to do because I can't hardly get anywhere. If I didn't have and iPad I would even be able to get here! Can someone help me or is my only option to take it to a repair shop??

Well we don't know what model your MBP is, but if you performed a 10.6.3 upgrade over 10.5, likely it didn't go correctly.
You can hold the shift key down, this will disable third party kext files in the System/Library/Extensions folder, look for third party types in that folder that belong to software you run and remove them. (carefully, some are needed by OS X) Ideally it's best to know which ones from the developers site.
If you don't have any files on the machine to recover, then hold c and boot off the 10.6.3 disk and use Disk Utility to Erase (with Security option Zero) and format the drive Partition: Option: GUID Format: OS x Extended (J), then quit and install 10.6.3 fresh. No iLife from the 10.5, but you can but it again from the 10.6.8 AppStore for chump change.
When you log in update to 10.6.8, then install programs and files from backup.
If you do have files on the machine that need to be recovered, use a blank external powered drive and c boot off the 10.6.3 disk, format it like above and install 10.6.3 on it, then you can reboot holding the option key down and boot off the external drive, go through setup and grab your files off the internal drive before erasing it.
Carbon Copy Cloner is also your friend, clones the whole OS X partition.

Downgrade Mountain Lion to Snow Leopard (Keep all data?)

I have Mountain lion and I am about tired of it and I want to go back to snow leopard. I also have Time Machine but it has been awhile since my upgrade and I have changed many things that I do not want to loose.
Is there a way to downgrade to snowleopard and keep all my info as it is now? I would think restoring via time machine would restor the OS as well?

Downgrade Lion/Mountain Lion to Snow Leopard
1. 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.
2. After DU loads select your hard drive (this is the entry with the
      mfgr.'s ID and size) from the left side list. Note the SMART status
      of the drive in DU's status area. If it does not say "Verified" then
      the drive is failing or has failed and will need replacing. SMART
      info will not be reported on external drives. Otherwise, click on
      the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions
      from the drop down menu to one. Set the format type to Mac OS
      Extended (Journaled.) Click on the Options button, set the
      partition scheme to GUID then click on the OK button. Click on
      the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion/Mountain Lion files.

Severe Glitch with Snow Leopard keeping settings

Hey there.. Im havin.. a huge issue on my mac.. I opened it up today and.. to my dismay.. all my settings, Dock items I added, stacks I added, ANYTHING I changed on my mac had been lost and it reverted to a brand new state except all my files are still on the system. I also lost my 3rd party drivers, as my HP printer is now using cupsd and not the HP driver. Apple needs to have its engineering team look at my logs but that gonna take a week so I was wondering if anyone had this problem.. Last tidbit of info.. I ran a permissions check and 2 points of interest caught my eye:
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired.
Warning: SUID file "System/Library/PrivateFrameworks/DesktopServicesPriv.framework/Versions/A/Reso urces/Locum" has been modified and will not be repaired.
Having some knowledge of Unix.. i dont think whatever these files are governing is good if theres a problem with them.

Some of you mentioned guest account... well not to hijack or anything but:
So today, I turned on my macbook pro like usual, but accidentally clicked guest account. It sat there trying to load into it for several minutes, so I held down the power button till it shut off.
I then turned my MBP back on and logged into my normal admin account, though when I did I noticed that my settings and preferences had been reset.
But somehow it went from 20 gigs available to 80 gigs available, I figured it was a permissions error, so I ran disk utility from my snow leopard cd, repaired the disk and reset the permissions.
and those 60 gigs lost were files for my business / clients / work / school. Only things left are my applications and itunes folder. My apps when run, seem to be running for the first time ever.
I was/am running the latest version of Snow Leopard.
I don't know what else to do, or why this happened. And no, I hadn't backed up in a while. Not these files, everything else, yes. The stuff that isn't quite so super important :/
any ideas? ive run permissions reset several times, and disk repair but nothing.

Mac on Snow Leopard keeps looping back to login screen

Hi, Everyone,
I have a MacBook, late 2008 It originally had 120 GB hard drive. Because I had less than 10 GB of space left, I replaced that with a 320 Western Digital Scorpio Blue HD (by myself, with an antistatic strap, etc). Everything seemed fine for a few days. Lots of space, immediate responsiveness with programmes, etc....nothing could be better. Then the system started getting sluggish, and I started getting spinning beach ball clicking between apps. Every time I ran verify disk permissions, there was a long list of permission repairs. Running repair disk never yielded a result other than everything being okay. I even created a flashdrive with the installation software. And I ran Onyx to try to clean things out.
Then a few days ago, after restarting my computer (I may have done an update, but am not sure), my computer slowly booted up, came to the login screen, I entered my password, my desktop appeared and it "hung" for about 30 seconds, then the screen turned blue and went back to login screen. I made several attempts to login, but always got the same result.
I used my bootable flashdrive (which I created with SuperDuper to contain the installation disk before I installed the new hard drive) to check and repair permissions. Each time I did that, I got the same permission errors. Again, nothing detected with disk verification/repair.
When I start up the computer in safe mode, everything is fine except Safari kept crashing.
Deleted and reinstalled safari to no avail. Still crashed. No problem in Firefox.
In the regular mode (not safe mode), I reinstalled Flash, restarted, then back to the looping to the login screen.
Still no problems in safe mode.
At first I thought there would have been something with the new hard drive, but everything works fine in Safe Mode, so I'm wondering if there is something with Safari or Flash.
I've updated ClamX and run a ClamX scan as well to check for viruses/Trojans.
Please help.
Help!

Okay, I reinstalled Safari under another admin account. No problems there, and --so far--no problems in my main account now.
What has happened is this.
You installed a new hard drive, it came from the factory with some bad sectors on the drive.
You laid your new OS X and data over these bad sectors and now having issues in various locations.
The drive automatically maps off these bad sectors when it gets a read request from something your using, however it takes some time before it realizes such is the case, (thus the spinning beach ball as OS X is waiting) then it moves the data to a new sector and maps off the old one.
Also as you use the computer, your writing data to new bad sectors on the drive, which haven't had their turn yet enough to be read and hopefully mapped off by the drive. This is why your problem appears to be changing as it goes on.
Look at your problem timeline:
Then the system started getting sluggish, and I started getting spinning beach ball clicking between apps.
This is likely a problem with the swap file which is stored on the hard drive when you run out of RAM memory with a lot of programs and files open.
The swap file was stored across bad sectors, which the drive couldn't read well and thus you got the OS X spinning beach ball effect.
This file location moves locations to free space on the drive, expands and contracts as you load things up to use.
Then a few days ago, after restarting my computer (I may have done an update, but am not sure), my computer slowly booted up, came to the login screen, I entered my password, my desktop appeared and it "hung" for about 30 seconds, then the screen turned blue and went back to login screen. I made several attempts to login, but always got the same result.
You have done a update, which added more data to the drive and/or triggered a response from OS X data written on a bad sector which has hung your computer.
When I start up the computer in safe mode, everything is fine except Safari kept crashing.
Safe Mode disables at boot software, video and other things so OS X is in a reduced state, the bad sectors are being avoided as their data is not being called.
Safari is crashing because it too is corrupted, which your later post you reinstalled it and now it's fine, because it was written to a clear space on the drive without bad sectors issues.
So your going about a "piece meal" restore method, next will be OS X, then all your programs, then a new user account because your User/Library will get screwed up etc., etc.
Instead of this long pain, just follow my first post instructions and it will cure everything in one clean shot
If the drive itself is bad and that's causing your bad sector problems, which you will soon find out and can get it replaced. The way your going it's going to keep giving you problems of various sorts for quite some time.
I also tried the SMART check and it passed--no errors or bad sectors.
That only provides a current bad sector count, which you say is zero, which is typical for a new drive as it hasn't read enough from the drive to find the bad sectors yet.
In order to really find bad sectors on the drive, software would have to continously read data written to the entire drive over and over and over again so the drive will finally "trigger" the mapping off process. This would take days or even weeks to complete on large drive, so obviously the software isn't doing this.
All drives come with a few bad sectors, the automatic mapping off process upon reads usually takes care of it, however you have more bad sectors than normal, which might have occured:
1: Higher than normal amount of bad sectors from the factory.
1: Bad drive from the factory causing bad sectors.
2: Your moving the computer while the drive is in operation that the heads struck the platters causing the bad sectors.
So a Zero Erase in Disk Utility, a fresh OS X install from the disk, fresh programs from original sources and vetted files from backup is the sure means to cure the whole mess. Bad sectors and data corruption.
The DU Zero Erase proceedure does a pretty adequate job mapping off failing sectors, it takes hours to complete and not days.
Bad sectors causes data corruption, so you really can't trust a previous clone or TimeMachine backup of this corrupted data to restore with (except vetted user files), some here have done that only to wonder why their problems returned after the zero erase was completed.
If you restored the new drive with SuperD from the earlier drive, you also might have carried data corruption from that drive over too.
So with a fresh install of everything, only thing that can be corrupted is your user files, which you restore from a clean backup and/or delete the ones causing problems.
Take care and good luck.

I can't boot my MBP or reinstall snow leopard

I have an old 2005 MBP (non unibody) using snow leopard. I urgently need to get it running again since it stopped booting up last feb 2012 and I haven't used it since as I'm using a desktop now. When I turn it on I get no chime and the screen goes grey with an alternating apple logo, and a no entry sign, and occasionally a folder with a question mark on it. When I insert snow leopard and reboot it allows me to select language, and the home screen comes up with the option to reinstall the OS. I have also been to the utilities>disk utilities and tried verifying and then repairing the HD. When verifying it says my drive appears to be ok, and when repairing it appears to have not fixed anything. I've then quitter DU and gone back to try re-installing snow leopard and although the progress bar estimates 30mins or so it takes hours, then gets to about 3/4 done and comes up with a failure message saying..
Install Failed
Mac OSX could not be installed on your computer
The installer encountered an error that caused the installation to fail.
Contact the manufacturer for assistance
Click restart to restart your computer and try installing again
I did have the installer log window open whilst trying this and the last line before the install failure message contains loads of stuff which means nothin to me but contained within this text is this "an error occurred while extracting files from the package " lexmark_laserdrivers.pkg". Underlying error=(error domain=BOMcopierfatalerror code=28....(loads more text after this..)
Any help would be appreciated!!
Thanks

Reinstall OS X without erasing the drive
Do the following:
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.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

Struggling to restore from Time Machine (2007 MacBook; Snow Leopard)

The hard drive failed on my 2007 MacBook. I had it replaced and the shop also installed Snow Leopard (this was what I was using prior to the fail).
I tried a restore from Time Machine and while a huge chunk of my new hard drive disappeared, I couldn't locate the files. I have since found them in the hidden /Volumes folder.
I have also learned that to do a full restore, I should have used my Snow Leopard install disk alongside the drive with Time Machine backups.
So...
1. Should I delete the restored file in the /Volumes folder and start again using the Snow Leopard install disk?
2. I want to upgrade to Lion (this is the furthest I can go with this MacBook). Can I do step 1 using a Lion install disk even though the Time Machine backup was created in Snow Leopard? (Confession: I'm not sure where my Snow Leopard disk is and I'm trying to avoid going through cupboards and boxes to find it)
3. is it laborious and risky to try to restore everything manually from the /Volumes folder? Where do I start if I decide on this route?
Thanks in advance for any advice.

I would try recovering the files manually first. If the result is unsatisfactory, then I'd boot up using the Snow Leopard DVD, run Disk Utility/Repair disk, erase and reformat the drive, and then install Snow Leopard. Reboot normally, and use Setup Assistant to restore from Time Machine. Completely update to 10.6.8 and then consider if you want to upgrade to Lion. There are no Lion disks - it is a download.

How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current Tiger Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Installer menu (Utilities menu for Tiger and later.) 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. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) 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.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade:
Purchase the Snow Leopard Retail DVD.
Boot From The OS X Installer Disc:
Insert OS X Installer Disc into the optical drive.
Restart the computer.
Immediately after the chime press and hold down the "C" key.
Release the key when the spinning gear below the dark gray Apple logo appears.
Wait for installer to finish loading.
E. If updating:
Download and install update(s)
Use Software Update, or
Download standalone updater(s).

How do you transfer from mini to imac with fire wire if iMac has Lion and mini has snow leopard

My logic board has gone on my mini(intel) and I need to transfer this machine to an iMac(with Lion) how do I do this as it doesn't seem to be working with my disc.My update to Lion was purchased as a download and the only disc I have is snow leopard to reboot.

If your Mac mini has a dead logic board then you will not be able to boot it at all, not even in Target Disk Mode. You would either have to get the logic board repaired, or remove the hard disk and either put it in a disk enclosure or connect it in some other way to the iMac.
The fact that the two Macs ran different versions of OS X is irrelevant, once you have the drive connected to the iMac you can run the Migration utility to migrate the user account and data.

ICal & Snow Leopard upgrade. iCal icon is now stuck on July 17th?

Hi everyone,
I have recently upgraded my Mid '07 Mac Mini from Leopard to Snow Leopard and have only come across 3 problems (None really major).
One of these is my iCal dock icon on my dock is stuck on July 17th rather than the present date unless the app is open. (I am aware that July 17 is the default icon).
I've tried the following to fix it and none have worked so far:
Relaunched Dock & Finder
Deleted iCal Preferences in User/Library
Copied the iCal icon with the date on to a variety of places
Removing the dock icon and dragging back in again
Created a new account to see if it's my account with the problem (The problem existed on the new account too).
I can seem to fix this but it was my quick reference to the day's date.
I hope someone can help me. Thank you.

I think only Leopard's iCal has the current date on the dock icon. Tiger and (I guess now) Snow Leopard keep their dock icon on July 17, which is the date that iCal debuted at the MacWorld Expo in New York in 2002. The only time it shows the current date is when the application is running. There is one very simple trick to get it updated and thats to have the app open at login (keep it hidden if you don't want it popping up every time you log on). Other ways include scripting and installing other programs but that can get kinda hectic. =/

Macbook Aluminium. Single, long beep upon startup and update to Snow Leopard wont work.

Hi, I recently formatted my late-2008 Macbook and installed Ubuntu. It didn't work so I formatted again and installed Leopard. When I boot I get a single long beep. When I try to update to Snow Leopard and reboot the OS still shows up as 10.5 (Leopard).
It seems to function normally besides all this. I have not touched the memory in this time and the OS recognises the full 4GB I have inside. I also did not touch the hardware, this whole problem seems to have been caused by my attempt to install Ubuntu.
Any help out there?
Thanks guys.

I have exactly the same problem for some days because I installed Ubuntu 11.04. Thanks God I found a way to fix it:

Go to the video on youtube and see how you got your EFI firmware flashed Reboot and the long beep should go away
