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 Pro Crashes after Installing Snow Leopard

I just installed Snow Leopard on my macbook pro that I've had for 5 years and ever since every app that I open crashes upon opening it. If it does not crash, it'll open the application but render it completely inoperable. The computer also loses mousetrack and keyboard abilities. This happens every time I restart my computer. My computer is also no longer under warranty and cannot run without power cord. Nothing seems to be working correctly since the update. Time to start looking at a new computer? Easy fix? Any suggestions are much appreciated. Thank you much.

J-UST-91,
which version of Mac OS X was installed on your MacBook Pro before you’d installed Snow Leopard? Was it working flawlessly under the older version? Do you make a backup of your disk just before installing Snow Leopard?

Strange behaviors on MacBook Pro before & after installing Snow Leopard

I am not sure if this is even a Snow Leopard issue. We have a MacBook Pro that up until recently had been running Tiger. A problem developed whereby we could not access the iTunes store. A message that the store was "not available at this time" came up repeatedly while at the same time another computer was able to make connections with it. In addition, when Firefox was opened, a prompt appeared to drag the Firefox icon to the applications folder. Even after this was done, the same prompt would appear during subsequent sessions.
We updated the OS to Snow Leopard, and the iTunes store problem was resolved. However, there are some other unusual things going on with other applications.
1. When Photobooth is opened, we get this message: "There is no connected camera."
2. When we open any of the Office applications, we are greeted with: "To open Microsoft Word (or Excel, PowerPoint, etc.), you need to install Rosetta."
3. The above-described issue with Firefox still occurs frequently. Even though Firefox is located in the Applications folder, there is now a volume named Firefox on the desktop. We can't get rid of it.
We don't know for sure if the Photobooth and Office issues were present right before the Snow Leopard installation, but they had worked properly in the past.
One thing we did do is a verify and repair of permissions. There were MANY that needed to be repaired.
In addition, right around the time SL was installed, the computer was frequently shutting off without warning. The mouse was also operating erratically. It was found that the battery needed to be replaced, as the existing one was expanding and was actually disrupting the operation of the mouse pad. Could this battery have been the source of these problems?
What are the next steps we should take?

I suppose your expanding battery problem could have caused some or all of these problems, but most of them sound like software issues.
If I were you I'd try a few things:
1. boot from your snow leopard install disk and repair your startup disk with disk utility.
2. repeat the repairs until no repairs are reported (the toilet paper principle).
3. repair permissions again.
4. if the problems persist, trash the preferences files for the misbehaving apps.
5. if the problems persist, delete the misbehaving apps and reinstall them.
6. it the shutoffs persist, try a PMU reset.
7. a PRAM reset would probably be a good idea too.
8. if none of that works, archive and reinstall.
there is a freeware utility called applejack that will also do most of this.
Details on all of these will be readily available with a google search.

Can I purchase Mountain Lion and make a flash drive bootable? I do not want to install it on my Macbook Pro. I have Snow Leopard on my Macbook Pro now, and due to my hard drive needing repair I need to boot off of another source, like my flash drive.

Can I purchase Mountain Lion and make a flash drive bootable? I do not want to install it on my Macbook Pro. I have Snow Leopard on my Macbook Pro now, and due to my hard drive needing repair, I need to boot off of another source, like my flash drive. I am in Paris and my Snow Leopard DVD is in Texas.

Mac OS X has a built-in disk diagnostic and repair program called fsck or file system consistency check. Here’s how to verify and repair your startup disk with fsck. As soon as you hear the startup tone, press and hold Command-S on the keyboard. Keep holding down those keys until you see a black screen with white lettering. This is called “booting into Single User Mode.” As the Mac boots in this mode, the screen reports each step of the process. The line should end in root#. Right after the root# prompt, enter the following: /sbin/fsck -fy
If repairing the disk in single user mode fails, it means one of two things. Either your hard drive itself is failing (a hardware failure), or the directory damage on your hard drive is beyond the capability of the built-in repair procedures in OS X.

Is it possible to install CS5 or CS5.5 on a 2.4 GHz Intel Core 2 Duo 4 GB 667 Mhz DDR2 SDRAM MacBook Pro running 10.6 (Snow Leopard)?

Is it possible to install CS5 or CS5.5 on a 2.4 GHz Intel Core 2 Duo 4 GB 667 Mhz DDR2 SDRAM MacBook Pro running 10.6 (Snow Leopard)?

Hi Carolyn, thanks for your quick reply. First thing I did before posting my question was to check the system requirements for Creative Suite, both on Apple and Adobe's websites. But I am however confused about the difference between "Multicore Intel processor" vs "Core 2 Duo", and keep hearing stories about CS5 not working properly.

2011s MacBook Pro won't install Yosemite neither reboot or boot into recovery mode.

Hello everyone, I've searched all around the web and didn't find a solution.
Sorry about my english, btw, I'm from Brasil lol!
I have a 2011s MacBook Pro, used to run Snow Leopard until 2 days ago, when I downloaded Yosemite and restarted the computer to run the installation.
During the process, it stopped at 22%, and said: FILE SYSTEM VERIFY OR REPAIR FAILED.
I tried to reboot on Macintosh HD as usual, but it's not possible, I can't unmount the HD to repair it, can't erase it and I'm a little desperate.
I have a good backup of important files on an external drive, so the best solution for me would be to format the HD again, with the Yosemite image which appears to be running at startup.
Command+ anything at startup doesn't work, probably because the Yosemite install is trying to run...
Any suggestions???
Thank you!

Hey Vince,
I have the same or similar issue. Please forgive my English, as I attended American Public schools
So last night, my MacBook Pro told me hey you want to download this free and amazing new OS called Yosemite?
(I'm adding to your post to hopefully grab more attention and then maybe grab a solution from someone out there..)
I thought yea, no, maybe, okay it's free, they say it is amazing-- why not?!?
So I downloaded and clicked okay to restart and install the new OS.......but it won't install the OS and I get stuck here on this screen.
I have tried restarting about 10 ties. I have tried quitting the install but it won't allow me to boot from Mac HD or my time capsule HD. I tried going into the menu options above but it won't let me repair or reboot or anything to get my MacBook to work again.
It is pretty frustrating. I went from having a working MacBook Pro to having a nightlight.
Vince- if you get a solution or a fix, Please let me know.
Thanks
john

The only observations are that the backup drive is deemed too small and the quite long list of diagnostic reports dated between Jan 18, 2015 (which I believe is the day I upgraded to Yosemite) & today the latest Yosemite update was installed on Jan 28, 2015
Any further assistance will be appreciated

While the 2011 MBP's that shipped with Lion can be made to run Snow Leopard as long as you have the appropriate installer disk for 10.6.7 or later, yours is a 2012 MBP and most likely can never be made to run Snow Leopard because the necessary hardware support drivers (e.g., USB 3.0 support) simply aren't a part of that OS.

Airport not maintaining internet connection on my D-link router with Macbook Pro 5.5 with Snow leopard

Airport keeps throwing me out of internet connection on my D-link router with Macbook Pro 5.5 with Snow leopard. Pls if anyone has a solution to this then let me know

I'm using my PC notebook because connecting with my iMac is IMPOSSIBLE!!! If I get connected at all, it's worse than dial-up speed.
We are wireless via a D-Link DIR-625 (new) -- but was having some problems before with a netgear. Problem much worse now. My computers are not the primary computers. My sister gets that coin toss. She is a PC user. I share with her using WPA2. When the iMac "wakes" the signal bands are strong, but when I go to a page I lose all signal strength. And several times a day I get a message indicating an error joining the network -- arghhhhh -- HELP!
Is the problem with D-Link or Mac? Thanks for any help.

Macbook Pro V10.6.6 Snow Leopard

I have a Macbook Pro V10.6.6 Snow Leopard. It looks like the OS crashed and it's not booting anymore. It's getting stuck at grey screen. I tried lot of things (could not boot in safe mode, Disk Utility do not show upon boot, Internet Recovery is failing with -2000F error, ...). It looks like i will have to reinstall the OS. However, I do not have the CD the came with the Macbook. Where can I download it from?

10.6 isn't available as a download.
If you've lost the Snow Leopard DVD you can buy it again at the Apple Store.

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.

White MacBook won't install Snow Leopard....help!

Hi,
I have 10.5.8 installed on my white MacBook (2 GHz Intel Core 2 Duo) computer.
I'm trying to install Snow Leopard, but during the installation, a message pops up saying "Mac OS X Snow Leopard cannot be installed on this computer".
Will 10.6 not work on this laptop?
Thanks!

You need to use a retail disk and not one which shipped with another Mac.

How do I reinstall my operating system after hard drive upgrade on MacBook pro? I have Snow Leopard install disc

How do I reinstall my operating system (Snow Leopard) after a hard drive upgrade. I did a Time Machine backup before the new hard drive was installed. I put in the Snow Leopard install disc and don't get the icon I'm supposed to double click to install Snow Leopard and then the backup.
HELP PLEASE!!

Is the new HHD in the MBP?
Is the new HDD formatted Mac OS Extended (Journaled)?
Where is the old HDD? In an enclosure? What is on the old HDD, your user data? Is the Snow Leopard System on it?
Do you have a separate Time Machine Disk with your user data?
Answers to these questions should give an exact status of your situation so that one can proceed in the right direction.
Ciao.
