HT1338 How do I update Mac OS X 10.4.11 to Mountain Lion?

I would like to upgrade to Mountain Lion but all installation apps require OS X 10.5 or greater.

Choose About this Mac from the Apple menu and check the processor.
If it's a G3, no further upgrades are available.
If it's a G4 or G5, buy a retail Mac OS X 10.5 DVD from a source such as Amazon or eBay; Apple still might have copies in stock if you phone them. It can't be upgraded past 10.5.8.
If it's an Intel Mac, buy a Mac OS X 10.6 DVD from the online Apple Store, install it, run the Mac OS X 10.6.8 combo updater, and then try buying Mountain Lion from the Mac App Store.

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 MobileMe service; 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)

         3. MacBook Pro (Mid/Late 2007 or newer)

HT1338 How to upgrade MacBook Pro from OS 10.5 (Leopard) to Mountain Lion?

How do I upgrade a MacBook Pro from OS 10.5 (Leopard) to Mountain Lion? Do I need to upgrade in stages, i.e. to Snow Leopard, then to Lion, then to Mountain Lion, or can it be a more direct route?
R.

Hi Richard,
You need at least 10.6.6 installed to get & use the App store for purchase & download, & just read that Lion/10.7 is no longer available!???
Snow Leopard/10.6.x Requirements...
General requirements
   * Mac computer with an Intel processor
    * 1GB of memory (I say 4GB at least, more if you can afford it)
    * 5GB of available disk space (I say 30GB at least)
    * DVD drive for installation
    * Some features require a compatible Internet service provider; fees may apply.
    * Some features require Apple’s MobileMe service; fees and terms apply.
Which apps work with Mac OS X 10.6?...
http://snowleopard.wikidot.com/
It looks like they might still have it...
http://store.apple.com/us/product/MC573Z/A?fnode=MTY1NDAzOA
It's been reported that if you have a MobileMe account, it may be free from Apple.
If it's a core Duo & not a Core2Duo, then it'll only run in 32 bit mode.
Lion/101.7 System requirements
    •    x86-64 processor (Macs with an Intel Core 2 Duo, Intel Core i3, Intel Core i5, Intel Core i7, or Xeon processor.)
    •    At least 2GB of memory, I say 6 GB
    •    Latest version of Mac OS X Snow Leopard (10.6.8), with the Mac App Store installed
    •    At least 4GB of disk space for downloading, I say 50 GB.
Like Snow Leopard, Lion does not support PowerPC-based Macs (e.g., Power Macs, PowerBooks, iBooks, iMacs (G3-G5), eMacs).
Lion also does not support 32-bit Intel Core Duo or Core Solo based Macs. Rosetta is no longer available in Lion, which means Lion no longer supports PowerPC applications.

What applications are not compatible with Mac OS X 10.7 "Lion"?
http://ow.ly/5Iz09
http://roaringapps.com/apps:table
Macs that will support OS X 10.8 Mountain Lion
As usual, the newer the Mac the better:
• MacBook Pro – 13″ from mid 2009 or later, 15″ from late 2007 and newer, 17″ from late 2007 and newer
• MacBook Air – late 2008 and newer
• iMac – models from mid 2007 and newer
• MacBook – 13″ aluminum from 2008, 13″ from 2009 and newer
• Mac Mini – early 2009 and newer
• Mac Pro – early 2008 models and newer
• XServe – early 2009 models and newer
Macs that are NOT expected to support OS X Mountain Lion
Older Macs and those with weaker GPU’s will likely be left behind:
• Anything with an Intel GMA 950 or x3100 integrated graphics card
• Anything with an ATI Radeon X1600
• MacBook models released prior to 2008
• Mac Mini released prior to 2007
• iMac models released prior to 2007
• Original MacBook Air
This list of compatible and incompatible Macs and system requirements are based off of the first OS X Mountain Lion Developer Preview and may be subject to change, we will update when we learn more about the specifics. OS X Mountain Lion will be released this summer but presumably long before that we will know precise system requirements and what Macs are and are not supported by the new version of OS X. Stay tuned.

How can I get Mac Mini to accept bootable installers for Mountain Lion ? They work fine on MB-Pro

I've had a Mac Mini (late 2012) for the past week and need to do a complete reinstall to get rid of very mucked up Server.app settings that I can't get rid of even though I uninstalled Server.app and what I thought were all of its Library files. I need to get the Mac Mini back to pristine, factory default to start over. Then I'll be able to put Server.app into a VM so I can trash it if need be without mucking up the rest of my system.
I have both a bootable recovery partition on an external hard drive (My Book firewire) and a USB bootable installer with a fresh edition of Mountain Lion. I know the USB installer works just fine because I used it to do a clean install of my MacBook-Pro just last night. Went like a charm.
When I start up the Mac Mini with the option key held down, everything seems fine -- I see both the USB drive and the My Book's 2 volumes (1 for data, 1 for the Recovery partition). But when I select either the USB drive or the My Book Recovery partition as the start-up drive, I get a screen with a circle with a line across (the no-entry traffic sign), with no way to go back or forward. So the computer has to be rebooted.
Any suggestions as to how to get the Mac Mini to recognize bootable installers that MacBooks are able to see?

Late 2012 Mac mini uses a special Mountain Lion version that it's only compatible with this Mac and you can only get on Internet Recovery because it's not available in the App Store. If you want to reinstall Mountain Lion, press Command, Option and R keys while your computer is starting

How can I update from Os X 10.6.8 to Mountain Lion 10.8.4?

I am trying to update my Mac from OS X 10.6.8 to Mountain Lion 10.8.4. I have read online that I can no longer buy Mountain Lion from the App Store, and that I must purchase Mac X Maverick instead, but cannot find that on the App Store either. All I want to use this eBay computer for is for iTunes radio, which needs OS X 10.7 or greater. Could someone point me in the right direction for updating? I'm a grandma, fer Pete's sake! : ) Thanks to anyone who can help me.

Open the Mac App Store and try downloading Yosemite. If you get told it's incompatible, 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.

HT1338 How do I update my 2009 Macbook OSX 10.5.8 to Mountain Lion?

I'm not even sure this is possible... My computer has stopped recieving updates so it looks like it's about time for an upgrade but I haven't a clue where to begin given how old my current software is. I read the requirements for Mountain Lion and my computer is compatable but I'm still quite confused. Please help!

Buy or Obtain an OS X 10.6 Snow Leopard disk. These cost $29.99 a peice, and is required to use the Mac App Store.
Run software update. You only need to install the OS X Update. You don't have to update other things like itunes until you have Mountain Lion.
When you have the Mac App Store available, launch it. Locate Mountain Lion. Should be on the front page. Buy it with your iTunes account, similar to buying a song or an iOS App. It will download an Installer application. If the application does not launch automatically, launch it. This application will lead you through all the steps required.
Before you update, make a backup, if you have not already made one. Do not use Time Machine if you are on 10.5.8. Use something like Carbon Copy Clonor. (Google it). You should probably back up your entire disk.

I checked @ http://www.apple.com/osx/whats-new/features.html#reminders and it says under Multi Accounts: "Reminders works with CalDAV services like Google Calendar and Yahoo! Calendar. You can also create reminders that appear only on your Mac."

Does anyone have a listing of upgrades/updates needed to go from Snow Leopard to Mountain Lion?

I have an older MacBook running 10.6.8 Update and would like to move to the newer OS X versions. When I check updated software the search indicates I'm up to date. How do I go from 10.6.8 to Mountain Lion?

Choose About this Mac from the Apple menu, click on More Info, and check the model identifier against the following, which are the earliest Macs of each type that can run Mountain Lion and newer:
iMac7,1
MacBook5,1
MacBookPro3,1
MacBookAir2,1
Macmini3,1
MacPro3,1
Xserve3,1
If you choose to upgrade to Mountain Lion, click here; it isn't necessary to upgrade to Yosemite. Neither Yosemite nor Mountain Lion support PowerPC software such as Microsoft Office 2004.

How do I move from os x 10.5.8 to Mountain Lion?

How do I upgrade from OS X 10.5.8 to Mountain Lion?

You have enough memory, however it can be bumbed up to 8GB
(2-4GB modules) 2 - 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM
Install/upgrade RAM or storage drive in Mac's
You have a Intel Core 2 Duo and a old NVIDIA GeForce 9400M, so 10.8 is going to run slow.
10.6.8 max would be best for that machine as it's 4 years old, in it's near end of life stage.
If you backup your files off the machine to a Storage Drive, then erase and install 10.6 fresh from the disk, the machine will run very fast, because 10.6 has updated video drivers.
Most commonly used backup methods
How to erase and install Snow Leopard 10.6
You can then choose to go to 10.8 from there, but it's not going to be as fast as 10.6 is.
If you upgrade 10.6 over 10.5, then go to 10.8, your machine is going to crawl really bad, so somewhere you have to do a fresh install to get your performance.
You will have to call Apple via phone and order the 10.6.3 white retail disks, they only take phone orders for that disk now.

I have installed the most recent version of Snow Leopard on my MAC, and I am trying to install Mountain Lion from the Apple Store. It will not install, because it says I do not have 2GB of memory, even though I have over 200GB available. Please help.

Welcome to the Apple Support Communities
One thing is the memory, and another thing is the hard disk space. You are telling me that you have 200 GB of free space on the hard disk, but the App Store is telling you that you have to install 2 GB of memory or more on your Mac if you want to upgrade to OS X Mountain Lion.
First of all, open  > About this Mac > More Info, and copy "Model Identifier" here, so we can know what Mac you have got and how much memory you can install.
We recommend to buy the memory in OWC or Crucial (Crucial is cheaper and offers the same compatibility warranty as OWC) because you won't probably have any problem with the memory you buy there
