Upgrading an iMac from 10.1.5 to 10.3

Hi,
I'm having trouble upgrading an old iMac from 10.1.5 to 10.3. When I click on the install icon from the CD, it restarts the computer, but just takes me right back to the desktop without running the installation.
When I restart by holding down "c", it won't let me boot up from the installation CD.
I installed the firmware 1.4.9 update on the OS 9 Operating System, and that didn't make a difference.
I only have 64 MB of Memory, but 10.1.5 works fine on the iMac.....
Can anyone help?

How do I find the CPU speed on 10.1
This works on 10.3, maybe it works for you on 10.1
In Terminal type
sysctl hw.cpufrequency
and press return. The result will be in Hertz so you will need to divide it to get Mhz.

I have just purchased an iphone 4 and it needs me to have the latest itunes on my computer. I have not upgraded by computer for some time and thought this is probably the time to do it. My computer is an imac intel with Tiger 10.4.11. I want to upgrade my Imac from tiger 10.4.11 to Mac OS 10.6 Snow Leopard or higher. What is the best way to do this? Appreciate any help as I am out of practice. I used to be an old hand at this, but things have moved on since I didn't upgrade or use my computer as much!

The best way, really the only way, is to purchase Snow Leopard.
Online (UK): http://store.apple.com/uk/product/MC573/mac-os-x-106-snow-leopard
Elsewhere: call the phone number in the Apple Online Store.
Apple's price is $19.99, £14.00, €18.
Snow Leopard is not available to download from any legitimate source.
Once you install Snow Leopard, upgrade iTunes to version 10.7 or the latest, iTunes 11.
iTunes 10.6.3 is the last version of iTunes to support Mac computers with Mac OS X 10.5.8 with either Intel or PowerPC processors, but since you have an Intel iMac, the best solution is to purchase Snow Leopard. Leopard is no longer available from Apple and prices from aftermarket vendors can be unreasonably high.

I want to upgrade my Imac from 10.6.8 to 10.8.5. Will I lose all of my programs and need to reinstall them? ie Microsoft office and Adobe suite.

Welcome to Apple Support Communities
You won't lose any app by upgrading to OS X Mountain Lion, but you have to make a backup of your files with Time Machine before upgrading and check that your apps are compatible > http://www.roaringapps.com If your applications aren't supported in Mountain Lion, delete them or update them before upgrading to OS X Mountain Lion.
After checking it, upgrade to OS X Mountain Lion. OS X Mavericks will be launched in weeks and will include new features, so you may want to wait until the Mavericks release > http://www.apple.com/osx/preview

How do I upgrade my iMac from OSX10.5.8 to Mountain Lion?

How do I upgrade my iMac from OSX10.5.8 to Mountain Lion? I'm guessing I have to first purchase Snow Leopard? Is there anyway to download or upgrade online?

First, determine how high you can upgrade.
SL requires an Intel processor and 1 GB RAM, though more RAM is better.
Lion requires Core2Duo processor and 2 GB RAM, though more RAM is better.
Mountain Lion has higher requirements: http://www.apple.com/osx/specs/
Also review applications that do not work under Lion or ML to see if you will lose critical functionality: http://roaringapps.com/apps:table
Research first, as too many have discovered only after the upgrade that things are lost to them.
You can buy SL or Lion from 1-800-MY-APPLE. SL is a disk ($19 single disk license, $29 for 5-user license). Lion will be a $19 download code to use in App Store that you get with SL.

Hi i want to upgrade my iMac from Snow Leopard 10.6.8 to OS X Mavericks or OS X Yosemite. My software update menu dosnn´t find any updates available. Help please, what can i do to upgrade to OS X Mavericks or newer version?

Open the Mac App Store and try downloading Yosemite. If you get told it's incompatible, the computer's also incompatible with Mountain Lion and Mavericks; if desired, choose About this Mac from the Apple menu, check if the computer has at least a Xeon or Core 2 Duo(not Core Duo) CPU and 2GB of RAM, and if it does, click here and order a download code for Lion 10.7.
Back up your data and check your applications for compatibility before upgrading. In particular, Mac OS X 10.7 and newer don't support PowerPC programs such as versions of Microsoft Office prior to 2008.

Problem activating Facetime on iMac: I recently upgraded my iMac from Snow Leopard to Mountain Lion.

I have tried (again later) repeatedly without success. PLEASE HELP!

When attempting to upgrade my iMac from Snow Leopard to Mavericks, I receive the message "This disk is used for Time Machine Backups" when I try to select the lone available hard drive.

When attempting to upgrade my iMac from Snow Leopard to Mavericks, I receive the message "This disk is used for Time Machine Backups" when I try to select the lone available hard drive. I have ensured that Time Machine is turned off. Upon some Google research, some who reported this problem were told to delete the folder backup.backupdb, but I do not have this folder on my Mac. Any suggestions?

The folder would be at the root of your hard drive. Double-click Macintosh HD and look there.
If it isn’t there, I’m not sure what it is seeing.

Is it a good idea to upgrade my imac from 10.6.8 snow leopard to osx maverics?

I am thinking of upgrading, any problems with this come up? thanks for help!

Do you have a realistic need to upgrade, for example, to run certain new software that requires it? If you do upgrade you will lose the ability to run all PPC software such as Office 2004, AppleWorks, and many others.
Older Macs like yours will usually run faster with Snow Leopard. And, upgrading will require you to add more RAM to your computer. 2 GBs is simply not sufficient. Otherwise, see the following:
Upgrading to Lion
If your computer does not meet the requirements to install Mavericks, it may still meet the requirements to install Lion.
You can purchase Lion at the Online Apple Store. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mavericks
You can upgrade to Mavericks from Lion or directly from Snow Leopard. Mavericks can be downloaded from the Mac App Store for FREE.
Upgrading to Mavericks
To upgrade to Mavericks you must have Snow Leopard 10.6.8 or Lion installed. Download Mavericks from the App Store. Sign in using your Apple ID. Mavericks is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
    OS X Mavericks- System Requirements
    Macs that can be upgraded to OS X Mavericks
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
     Are my applications compatible?

Can i upgrade my Imac from 10.5.8 to snow leopard?

So i have an Imac from around 2006, id IMac 7,1 with no upgrades, just the basic. Its currently on 10.5.8 software (Leopard), but i do have the dvd disc for snow leopard (10.6). Is it possible to upgrade the software on the mac, as i heard it wasnt from a friend. Also if i can use the disc to upgrade, what would happen to all the programmes (e.g word, photoshop) and pictures, videos etc. or would it be totally fine?

The system requirements are printed on the box. If you have an Intel Mac, which it seems you do, it should support it. I would strongly advise that you max out the RAM before you attempt to install it.
Applications you have installed now should remain in place when you upgrade, as should data.

Upgraded my iMac from 4 to 8 Gig, now lost all iPhoto images, can someone please help?

Can I use the install disc from my macbook to upgrade my imac from Tiger?

I have an imac which is on Tiger. I recently bought a macbook which is on snow leopard. I have the install discs for Snow Leopard and I was wondering if I could use them to upgrade my imac.
Also, if I can, will it delete existing files and software that's already on it?
Thanks.

No. Besides being illegal the DVD that came with MacBook are hardware specific to it and will either not work at all or not work properly if you attempt to use them on the iMac.
Just go out and buy the $29 DVD for Snow Leopard. It is easier that way.
