Back up your data, install at least another 1GB of RAM(you should install another 4GB) in the machine, click here, and read the entire page. Mac OS X 10.7 and newer don't support PowerPC software such as Microsoft Office 2004; some other installed software may also be incompatible.

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.

How do i upgrade my iMac to two TB hard drive start to finish?

How do I upgrade my Imac to two TB hard drive start to finish?

Those are definitely good drives. The OP lists his iMac as a 2011 unit, so it should have a Thunderbolt port on it. If money isn't an object, he could probably put together a RAID unit using Thunderbolt. I think OWC is selling an Thunderbolt hub of some sort. He could do all this, get good performance, and not even need to bother cracking the case. It's a lot easier and convenient working on an external drive than it is having to service an internal drive. He just needs to steer clear of some of the low power/backup drives.
Just my two cents, of course.

How do I upgrade my iMAC OS X v10.5.8 to Snow Leopard?

How do I upgrade my iMAC OS X v10.5.8 to Snow Leopard?

And it is very easy to install in contrary to earlier system versions. Don't forget to do the Software updates for the system as you might not get the latest version on the disc. Best is to download the 10.6.8 COMBO update (1 Gb) first before updating.

HT1338 how can i upgrade my iMAC OS X 10.4.8 version to 10.7 ? Not so computer literate

How can i updgrade my iMAC OS X 10.4.8 version to 10.7 ?? I'm not so computer literate but my computer is considered old and it is in desperate need of the latest upgrade. Also, how much is the cost for upgrade? Many thanks to you Apple folks...

You don't require Leopard.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
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 iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. 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 Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 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 Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         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?
         See App Compatibility Table - RoaringApps.

You do not have upgrade your OS X version to get a better Web browser experience.
Try using another web browser, instead.
Stay away from Google Chrome and any Googkewares for the Mac.
Download and install Mozilla FireFox, instead.
The current, up-to-date version of FireFox is fully compatible with OS X and is regularly updated by the great developers of the Mozilla group.

How can I upgrade my iMac G3?

Hello, I have an an old, blue, slot loading iMac with a PowerPC G3 processor running at 350MHz. This computer is running Mac OS 9.0.4. I have 65 MB of virtual memory and 64 MB of built-in memory. The hard drive storage is 7 GB and 16% full. I am connected to ethernet and currently have only Microsoft Internet Explorer 5 Macintosh Edition as my way to the internet. Please ask if you need more specs.
My goal with this computer is to upgrade the software to the most advanced the machine can handle.
Attempts to reach this goal based on forums about similar topics:
I have tried to update the firmware to 4.1.9 by downloading it to the computer I am using to write this review then copying it to a flash drive. This did not work because the iMac said it will not open the software because it could not recognize the developer. (Was this necessary?)
I have tried to update the software to Mac OS 9.1. I downloaded it to the computer I am using to write this review and burned it to a disc. I put the disc in and followed the instructions given by an apple forum post to install the software. This did not work because right before everything is about to start going my way the iMac gives the message that you have to be on an administrator account to update the software, which leads me to the next attempt. (Was this necessary?)
I have tried to override the administrator password, which has been long forgotten, by pressing command + s while the computer is booting up. This does not work since Mac OS 9 does not have a terminal. You have to have Mac OS X to access the terminal during boot. (Is there another way to override the administrator password?)
Please help me out keeping my end goal and specifications in mind! Don't be afraid to ask if you need more information!

How do I upgrade my imac g4 to OS X Tiger

I have recently been donated a 2003 (800Hz) imac G4, which had never been connected to the internet until now! It is not exactly perfect but after a bit of on line reseach I discovered that I need to buy OS X Tiger installation disks to upgrade.
On ebay etc it seems that I can buy a secondhand CDrom considerably cheaper than the DVD although the mac does have a DVD drive and I understand the CDrom is for earlier versions. Will it make any difference which type I buy?

Tiger install DVDs are in short supply. Tiger is no longer available at the Apple Store but may be available for $129 by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753). For other sources, do a Google search for MA453Z/A (10.4.6), MA190Z/A (10.4.3) and M9639Z/A (10.4) . Also look on eBay. Be sure & buy a retail version (black with silver X) and not a model specific version (gray) (See Can I use another Mac's system restore disc on my Mac? ). Expect to pay (possibly a lot) more than the Apple list price of $129.
Also check these web stores: http://www.lacomputercompany.com/cgi-bin/rpcart/index.cgi?command=dispitem&type= sku&sku=19521 http://www.allmac.com/shop/index.php?cPath=5_10003
After you install the base 10.4.x, update to the final Tiger version 10.4.11. Here's the link for the 10.4.11 combo update http://support.apple.com/kb/TA24901?viewlocale=en_US
Look at this link Mac OS X v10.4 Tiger Installing Software Support Page
http://www.apple.com/support/tiger/install/
You can also download the Tiger Installation and Setup Guide
http://manuals.info.apple.com/en/TigerInstall_SetupGuide.pdf
When you upgrade the OS, do it via Archive & Install. See About the Archive and Install feature http://support.apple.com/kb/HT1710
Be sure to select Preserve Users & Settings. Also, repair permissions before and after the install.

How can I upgrade from Snow Leopard to Mavericks?

The thing is, some of my software doesn't yet work in Yosemite, and doesn't in Snow Leopard. I'm on an iMac (≈2010). I haven't downloaded Mavericks on anything else, so I don't have it in the app store, but I got a Macbook which came with Mavericks. Is it possible to do this?

No. Apple has removed Mavericks from downloading since the release of Yosemite.

HT3606 How do I upgrade my OS X from 10.5.8 to v10.6.7?

How do I upgrade my IMAC OS X from 10.5.2 to v10.6.7? What are the system requirements?
Thank you for any help!

Following Neil's post ... the DVD will arrive as 10.6.3. You should then update it further, via the combo update, to 10.6.8 which will bring you the App Store.
I know you haven't asked but If you hope to go further, read up on the OSX system requirements. Some early intel machines may not work with Mountain Lion, for example.

I upgraded my iMac OS to OS X Mavericks and now I my CS2 InDesign files won't open?

How can I access my old InDesign CS2 files after I upgraded to iMac OS X Mavericks operating system?

Yes thank you - I have done that and it worked - for one month while I have a free download. But I ultimately have to pay. I don't think it's fair to sell software, make it obsolete and then charge customers to upgrade.
