Dvd won't read snow leopard

I finally decided up upgrade to Snow Leopard; when I put in the disk, nothing happened, and the disk got kicked back out. Suggestions?

Is your optical drive able to read other disks - movie DVDs, music CDs, burned data? If so you may have a faulty Snow Leopard disk. If all disks are failing, however, it is likely a problem with the drive itself, which will need service.
Best of luck.

My MacBook running 10.5.8 won't load Snow Leopard. I can hear the disk drive trying, but then it just ejects. I have run the repair disk permissions, no luck still. Any advise?

My Mac Mini won't acknowledge Snow Leopard disk to upgrade OS. DVD drive works fine.

Purchased my Mini January 2009 with 2 GHz Intel Core 2 Duo processor w/ 2 GB 667 MHz DDR2 SDRAM. Trying a long-overdue upgrade from OS 10.5.8 to Snow Leopard, the computer won't acknowledge the disk, and the DVD drive runs other disks.
According to other links here, I should be able to upgrade through OS 10.7 without problem, correct? (FYI, I have four USB ports on this thing.) Also, I noticed my Snow Leopard disk - purchased from Apple, not bootleg - is 10.6.3, which is what they shipped when I said OS 10.5.8 is in here. Am I missing an earlier version than 10.6.3? In any case, the disk just grinds awhile, then spits out. Nothing ever shows on the display.
I have 59 gigs of internal hard drive space available.
I'm not really tech savvy, so any thoughts?

Thanks for your response, and good call! I discovered the Mini will acknowledge other DVDs that I know have content, but displays them as blank; otherwise, it won't open/run anything. It's more than I knew before.
Looks like I'm heading to the Apple shop.

HT1338 why wont my mac mini read snow leopard disc, it will read other dvd's and cd's

I have a mac mini since 2009 I recently got the snow leopard from apple but when I insert it it in the drive it just makes a few noises then ejects the disc. I have tried other dvd's and cd's and it reads them ok any help appreciated

It's possible the DVD is damaged, scratched and/or dirty. Check out KB Articles: http://docs.info.apple.com/article.html?artnum=50448 How to Handle and Clean CD and DVD Discs and Troubleshooting Mac OS X installation from CD or DVD
Or you can request another DVD from Apple and/or get your $$$ back.
Your drive may need cleaning. Cleaning kits can be purchased from any store that sells CD/DVDs.

Mac intel pro won't recognize snow leopard installation dvd

i have a dual-core intel xeon with 6 GB memory. the dvd player reads all cds and dvds except when i insert the cd to install snow leopard, it ejects the disk. this is the second disk as i exchanged for a new one at apple store (where it was recognized on the computer there) any ideas, i really want to get going on CS5. helllllp (presently running version 10.4.11

Most likely it's a hardware problem: meaning the media drive ("dvd player" is the name of the movie playing software in Applications) is either dirty or defective. A reasonable first step would be to blow canned air through the drive. If that doesn't solve the problem, then try a recommended-by-Apple media drive cleaning kit. Also test the 10.6 installer disc on another media drive to see if "any" media drives can detect it.
Report back on results, please.

Computer won't install Snow leopard 10.6.3

I am trying to upgrade from Leopard to Snow Leopard.
I have an imac desktop running 10.5.8. 2GHz Intel Core 2 Duo / 2 GB 667 MHz DDR2 SDRAM
Bought snow leopard install disc.
Disc starts to install and after a few minutes says "install will continue after restart."
Computer restarts
Disc ejects
My about this mac still reads the same infoMac OSX 10.5.8
Why isn't it upgrading to 10.6.3?

I don't think you did anything to cause the problem. It means the directory on the startup volume -- this keeps track of all the files on the drive -- is out of whack. I thought it might be the reason you couldn't install. If the computer came with Leopard, it should have come with the Leopard DVD.
You need to run Repair Disk.
Since you don't have the Leopard DVD to boot from to repair the Disk, several possibilities: if you have a bootable clone on an external drive, you can boot from that and run Disk Repair from Disk Utility there. Or you can boot into Safe Boot, which will run a directory check and try to repair the drive that way, if possible. To start up in Safe Boot, hold down the shift key when you hear the chime. Safe Boot will take much longer than a regular boot, so give it plenty of time.
If that won't work, then have a look at "Use fsck, if necessary" here. Keep running it until it comes up clean.

DVD-rom Scratch my Snow Leopard Disc

Hi All,
my early 08 mbp dvd rom put alot of scratch on my new snow leopard install disc.
although the installation went through smoothly.
I do heard that it was trying alittle hard to read the disc.
In the end i found lot of scratch.
Does anyone experience this before?
maybe a bad dvd rom lens?
Anyhow, I will still contact applecare for this.
Would pleasure if anyone here have similar problem with your dvd rom
please share your story.

Hi everybody,
I'm a new switcher and for that purpose, I bought a beautyfull MBP 2.8 recently (mid 2009).
Beginning with 10.5.8, and of course upgrade to 10.6.
When I was trying to do a clean install yesterday, I was surprised when the SL DVD was not able to mount, with a systematic auto-ejection, and more important, was not able to dvd-boot!
After that I tried with my 10.5.7 DVD installer, for the same result!
After some time, I looked the DVD's and I finally understood the reason: there are a lot of perfects circular scratches on all the DVD'S surface!(not one, but hundreds!)
I have to admit that my superdrive is more a super scratcher than anything else!
Let's go to my reseller now, with a big smile as you can imagine...

Macbook Pro won't install Snow Leopard

I am having trouble installing Snow Leopard on my Macbook Pro. I currently have Leopard 10.5.8 installed. I contacted Apple after my first issue. The tech support person decided I had a bad DVD & sent me a new copy, but the issue remains the same. When I try to upgrade I get as far as approving the user agreement and then the installation screen disappears. I tried installing using the DVD as the start-up as recommended in the installation instructions. When I do this I get as far as selecting the destination, but the hard drive has the yellow triangle with the exclamation point and says Mac OS 10 can't start from here. I have used the Disk Utility & Disk First Aid to check my hard drive & it checks out ok. Any ideas what I should do?

You could try doing what I call a repair install of Leo--installing Leo over Leo via upgrade. It is possible that you can reinstall Leo this way, and your problem will be fixed, even though you can't install Sno (yet). Also, you could try the Leo install from your desktop rather than having started to the DVD. I can't assess the probability that using this technique will solve your problem. I think it definitely is less than 50%. And, I emphasize that you may not even be able to do the repair install.

MacBook cannot read Snow Leopard disc

I've got a strange problem. I bought a Snow Leopard upgrade disc. I installed the new OS without any problems on my iMac.
Now, I cannot do it on my 15" MacBook Pro. When I try to insert the disc, the drive tries to read it for a little while, then spits it right out. It keeps doing it. After many attempts, I did eventually get it to read it once. The installer loaded, and began doing its thing. A short time later, when I came back to my MacBook, it had reset and still showed the original version of the OS. I assume it must have crashed during the install. Now I can't get it to read the disc again.
The disc itself is fine. It's not dirty. As I said, I installed it on my iMac.
I did read about similar trouble on another forum. People had replaced their discs but that didn't help. Anyone here have any ideas? I've had no trouble reading other DVD's in this drive, by the way. And I don't have any weird applications loaded, other than Norton Antivirus.

Yes, you can clone the installer disc to an external hard drive or flash drive (minimum 8 GBs) and boot from that.
How to Clone Using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
4. Click on the Restore tab in the DU main window.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the external or flash drive.
Source means the DVD.
Be sure your destination drive is partitioned using GUID and formatted Mac OS Extended, Journaled.
You can also install from another computer if you can connect the two by FireWire. See Installing Tiger without a DVD drive. The article applies to Tiger but will work with Leo or Snow.

My Mac won't install Snow Leopard?

Hello!
I own a 13" MacBook Pro, which I bought in 2010 (I think it's the mid/late 2009 model). It came with Snow Leopard.
When Lion OS X was launched, I downloaded it, and have been using it since then. To be honest, I've not liked it at all because it's a lot slower, and I don't really like all of this resumé business. I've only kept it because with University, i've not had much time to downgrade back to Snow Leopard.
But basically, I've got the time this week, and tried to install Snow Leopard yesterday - I tried this by inserting my original disks which came with my MacBook Pro, restarting the Mac, then pressing Option (Alt) to bring up the start-up disk stuff, and wiping the hardrive.
Yet, after wiping the hardrive, after asking it to start the Snow Leopard disc as the start-up disk, it wouldn't. The Apple logo loaded, the little loading wheel thing underneath it did, and it just stayed like that for ages - you could hear the disk spinning, then after about 5-10 minutes, the screen went black and I had to turn the laptop off.
It kept doing this so because I wiped the hardrive, my only option was to go to the Recovery disk and re-install Lion.
I'm thinking there could be a problem with the disc drive, but it works fine if i'm burning CDs/DVDs, or install software and that. So what is it that's wrong? Am I doing something that's wrong?
There's nothing wrong with the MacBook Pro discs because when I put them in the laptop when I've got Lion, it loads and asks if I wish to install Snow Leopard - of course though, it won't let me.
Cheers.

16X DVDs won't read

I have a G5 PowerMac (latest version I believe). It came with a SONY DVD RW DW-U21A installed. I tried replacing it with a Memorex DVD unit to be able to use 16x DVDs. It still won't read 16x DVDs even though the Memorex DVD drive will burn an dread them just fine in a PC. Is there a special drive that I need or is it a matter of the G5 not being able to read 16x no matter what?

I think you've got the same "software fault" that's affecting a number of us at the moment.. I'm was trying to log this with Apple but I'm just out of support so they won't help.. They wont even acknowledge my question.. Search on "DVD not reading blank media" or similar..

MacBook Pro will not read Snow Leopard install disc.

Trying to install Snow Leopard on daughter's MacBook Pro, which is still on 10.5.8 so that she can install Lion. Her computer refuses to read the Snow Leopard install disc and keeps kicking out the disc.

Are you using a retail 10.6 disk that looks like this?
and not the gray install disks that look like this? The Gray Disks are machine specific and only have the drivers for the Mac that they shipped with.

Battery update 1.4 won't install snow leopard

I bought a used macbook 2.0 2006 model. The battery in it was dead when I installed snow leopard. Now I have a new battery, but it will only charge to 92%. So, I installed battery update 1.2, which did nothing for the problem. Then I tried to install battery update 1.4 but could not get past the install screen. Is it because I have 1.2 installed and should I go to system core service and delete update 1.2 then install update 1.4

I have an update to my own post. Since I have a newly puhchased copy of Snow Leopard, I was able to call Apple tech support. Hear is what I found out from them. Battery update 1.4 is not compatable with Snow Leopard, it stops at Leopard. I still don't know why update 1.2 installed. I tried all the other things that Apple recomeds such as reset system management, zaping the pram and draining the battery.

Adobe reader snow leopard

Does Adobe Reader work with this version? I can't seem to open any pdf's. I'm using Snow Leopard 10.6.8. Thx.

When I installed Adobe Reader 10.1.0, the software asked if I wanted to default to Reader for all pdf's, to which I replied YES. How do I set PREVIEW as default. THX.
