Software Update, Upgrade: What's The Difference?
You should contact the vendor, and request a refund, or an exchange for a Full Retail Version, of the Tiger Install DVD.
If that is not an option, advise if you would like purchasing information.
Be sure not to, again accept grey, upgrade or machine specific CDs or DVDs.
The discs should look exactly like the images in the above links, and not say Upgrade, CPU Drop-in DVD, or "This software is part of a hardware bundle purchase - not to be sold seperately." on them.
If your Mac doesn’t have a built-in DVD-ROM player, you will have to use an alternative method of installation.

Can Not Install Mac OS X on this computer (MacBook)

Puzzles me: Brand new refurb. MacBook with 10.5 installed.
Repartitioned the drive to get two partitions and tried to use my Full Retail OS 10.5 disk to re-install.
Get error after the language selection: cannot install Mac OS X on this computer...
Same thing if I restart with an external drive and try to install from the retail disk to the MacBook's drive. I just can't imagine why I need to use the included machine specific disks instead of the retail version. I know it works if I take the drive out and mount it via FireWire to another Mac.
So what gives?

Your other answer had probably in the sentence.
I looked but could not find it so, as I remember, when Leopard retail came out with all the drivers and libraries for both PPC and Intel and some users were trying to install Tiger on new Leopard MacBooks and, like me, other cross installs, Apple released a short note that said only the install disk would work on the MacBook, not the retail. No reason was given. You have a better life because of it and your computing life is richer too.
Research Apple Partition Map and GUID. Do what you know works.

How full is your drive? You need at least 10/15% of free space.

Error Saying I Cannot Install Mac OS X On This Computer?

Hey,
I've been having a lot of issues with Leopard and all the 2.2 issues going around. I went to the apple store and he told me to use a retail DVD instead of the ones that came with my computer, since it appears only the 2.2 Macbooks are having the issue.
Well I inserted the DVD and booted from it, and after I select language it is telling me that I cannot install Mac OS X on this computer and to read the instructions for system requirements.
It has me completely baffled. Does anyone know why this would be? I tried with the disks my computer came with and it would work, so I completely erased the hard drive, and then tried installing from a bootable copy on my external hard drive. Same problem again.... It makes no sense to me, as he was able to install a copy on my computer at the store from his external drive (which he said was a regular retail copy, nothing special). Also, this is not the upgrade disk mailed out in November, it is the actual retail copy.
Any and all help will be greatly appreciated!

I would bring the computer and DVD to the store and show them the problem. Let Apple take care of it.

Mac Mini - Cannot install Mac OS X on this computer

I have recieved a Mac Mini from a family member as a gift - I believe it's an old 2010 model or so running 2.66 GHz, 4 GB RAM and 1TB (2 500gb) HDD.
I'm 99% sure the disc I'm using is the computers orginal disc.
I have gone about reformatting the computer like I have done with all my macs previously, however when I select a language when booting from disk, I will get the pop up error "Cannot install Mac OS X on this computer". I have tried wiping both hard drives, partitioning both hard drives but to no avail.
Help is much appreciated.

Having a go installing the Mini Server disc just incase - seems to be working?

My friend had this problem and he just went into his payment information to make sure it was accurate and up to date. He didn't even change anything, only reentered his security code. He then downloaded the app successfully. Thought that might help you.

Can not install Mac OSX Update Combo10.4.5 PPC

I have a clean installation of Tiger on a Power Mac G4 (AGP graphics) with Sonnet 1 ghz processor upgrade, updated to 10.4.3 by running Software Update. No other updates available at this time.
So I downloaded MacOSXUpdCombo10.4.5PPC.dmg and it stops at "Select a Destination."
"You cannot install Mac OSX Update Combined (Power PC) on this volume. This volume does not meet the requirements for this update."
I must have installed this update previously, to get to 10.4.6, to install Adobe CS3 which REQUIRES 10.4.6.
Now I can't figure out how I got this update installed - sorry if this has been posted previously.
This isn't my main machine, thankfully, but I use it as a spare in the studio to transfer images to.
Can anyone help me get this OS updated to 10.4.6?
I don't have the original processor, so re-installing it isn't an option.
Thanks.

No, I wouldn't ignore them, I think we really have more messed up than just this, and if any of these steps fix it, we'll likely need new downloads.
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
The usual reason why updates fail or mess things up, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates.
May even need to do an Archive and Install if you have room on the HD, but saves all your files and gives a new OS...
http://docs.info.apple.com/article.html?artnum=107120
I only use Software Update to see what is needed, then get them for real via...
http://www.apple.com/support/downloads/
That way I can wait a week or so, check the forums for potential problems, and get Permissions & such in order before installing.
If all the above fails, then it appears to be time for an Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space...
http://docs.info.apple.com/article.html?artnum=107120
Just be sure to select Preserve Users & Settings.

I can not install Mac OS from installer DVD?

I want to do a clean install of Snow Leopard and upgrade to Lion and none of my DVD's will complete a full install. Installer DVDs from 10.5 even have this problem. The installer process starts but when the computer restarts, the computer stops at the gray apple logo. This happens for all the installer DVDs that I have. I have a 2009 MacBook Pro. I have tried installing from an external dvd player. I have even tried copying the installer DVD to a flash drive, hard drive and dvd copy. All my media is in perfect condition. So it is not an internal DVD problem. Does anyone know if this might be a motherboard problem? Has any one else had this problem?

Apple Hardware Test (holding down D during startup) also fails

Can't install OSX 10.4 on this computer? But it used to run it fine!

Help! I have been running 10.4 since it came out... loaded from the black retail box. Then, last week, my HD was corrupted...to the point it would no longer function. I have replaced it with a 100MB drive from OWC. Everything installed fine...except 10.4. It would not install from the original retail disks.
I went back to the original 10.3.9 disks that came with the computer, and they loaded fine. I again tried to upgrade with the 10.4 disks, and same message!
The CS3 apps I have been running for two months are now unusable... can anyone help?

My message is the same as my subject: "can't install OS X 10.4 on this computer". No options, nothing.
What gets me is that it was running OS 10.4 from day 1! Then the HD died...

I can not install mac os x on my macbook. Please help!!!

Hello, I was trying to install Pro Tools on my Macbook. However, when I was asked for my password to install the program, i completely forgot it. I was only able to find disc 2 of the installation discs in attempt to restore my Mac OS in order to retrieve a password. When i called Apple, i was told that I would need to purchase Mac OS X all over again. After paying $149, I get home, and i get a message on the laptop saying that the program could not be installed on my computer. After researching, i figured i'd need to update my firmware. However, I do not see any macbooks under the available list for firmware updates. I tried to download one for an ibook, and it would not even open. Somebody PLEASE help me. I have purchased expensive software, and it is serving no purpose as of now. Any advice or input would be greatly appreciated. Thank you for your time.

The Mac OS X package you purchased isn't usable on your Intel Mac; it only contains resources for PowerPC Macs. You need the MacBook's original disks or the Mac OS X Server Universal Binary installer.

I recently purchased an iMac with Maverick system. I want to know can I install my Photoshop CS5 on this computer then upgrade it to CS6 without a months charge in the cloud?

I recently purchased an iMac with Maverick system. I want to install my Photoshop CS5 on it, is that okay?
Then I want to update it to CS6 without the iCloud purchase monthly (don't want that, want a one time charge)???

As per System requirements | Photoshop, PS is not officially supported on Maverick and you might face several compatibility issues as well. However, we have many users who are still using CS5 on Mavericks. So, if you want you can give it a try and check it for your self.
As far as CS6 is concerned, you can get PS CS6 perpetual version easily from Adobe.com Creative Suite 6
Hope that Helps!

Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s MobileMe service; fees and
           terms apply.
Actually, you cannot download Snow Leopard. You downloaded a Snow Leopard updater.
