Can I upgrade to Mountain Lion from Leopard for free?

Hi Apple Support,
I was in the Apple, Covent Garden store the other day and an assistant said that I could upgrade to Mountain Lion from Leopard for free in one CD. He told me to call a number which I did and the assistant over the phone had no idea about this offer.
Can someone dispell the confusion for me?
Thanks

You can't. The Mountain Lion upgrade is only free for people who purchased a new Mac on or after July 26 without it installed, and all of the computers which fall into that category shipped with Lion, not Leopard.

If your system's not compatible with 10.8 and has at least a Core 2 Duo(not Core Duo) CPU, phone the online Apple Store and order a download code for 10.7.

Can I upgrade to OS X Lion, and then reformat my computer with the OS X CD?

Can I upgrade to OS X Lion, and then reformat my computer with the OS X CD? Because if I reformating my mac with the regualr OS X CD, would that erase the Lion? Since I just donwloading the Lion, and don't really have a CD for it.

If you install Lion then erase the drive that will erase Lion. To purchase and download Lion you must first install Snow Leopard 10.6.6 or later to access the App Store where you purchase and download the Lion installer. You might read this before:
Make Your Own Lion Installer
1. After downloading Lion you must first save the Install Mac OS X Lion application. After Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing Lion.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to several hours depending upon the drive size.
3. Locate the saved Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the InstallESD.dmg disc image to the flash drive as follows:
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the InstallESD.dmg disc image file into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable Lion installer that you can use without having to re-download Lion.

Can I upgrade to osx mountain lion Or to something higher than what I currently have and if so how?
Thanks!

Start by checking if you can run Snow Leopard:
Requirements for OS X 10.6 'Snow Leopard'
http://support.apple.com/kb/SP575
The OS 10.6 Snow Leopard install DVD is available for $19.99 from the Apple Store:
http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
and in the UK:
http://store.apple.com/uk/product/MC573/mac-os-x-106-snow-leopard
but nobody knows for how long it will be available.
When you have installed it, run Software Update to download and install the latest updates for Snow Leopard to bring it up to 10.6.8.
You should now see the App Store icon, and you now need to set up your account:
http://support.apple.com/kb/HT4479
To use iCloud you have to upgrade at least to Lion, but some functions are only available in Mountain Lion:
http://support.apple.com/kb/HT4759
You can also purchase the code to use to download Lion (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:

Can I install Max OS X Lion from Tiger 10.4.11? If so, how can I do it?

The questions is simple,
I want to buy Mac OS X Lion and install it on my macbook. I am using OS X Tiger 10.4.11. The problems is that it seems that in order to instal OS X Lion it is necessary to have the last version of OS X 10.5 (Snow Leopard).
So the question is, Can I install Max OS X Lion from Tiger 10.4.11? If so, how can I do it?
Thanks in advance,
Best regards,
Jesus P.

I have mac OS X 10.5.8, can I upgrade to OS X Lion without going through OS X Snow Leopard?

can I upgrade to OS X Lion without going through OS X Snow Leopard?

Yes.
Instead of upgrade, you can do fresh install Lion into another partition and so you would have multiboot 10.5.8 and 10.7.
If you wish to use the the exisiting 10.5.8 partition to install 10.7 Lion, you can first create a 10.7 DVD. And use the 10.7 DVD to do installation instead.
Here is how to create 10.7 DVD.

Can i reinstall OS X Mountain Lion from scratch from a Time Machine Backup

Can i reinstall OS X Mountain Lion from scratch from a Time Machine Backup
Asking because i'm a new mac user having used windows since 3.11, wanting to know if the Time Machine bacup was enough or will i need to make a seperate OS install disk or usb drive ???
thanx in advance guys

Lizardcarter's instructions are correct, you can (and possibly should) consider a second external HD to create a bootable clone. Redundancy in backups is a very good thing because backup can fail too. A bootable clone is an external HD that has a mirror of your internal HD so if the internal HD does crash you can boot from the clone, something that cannot be done from TM. This means you will be down for minutes and can resume work until you have had the internal HD replaced. Never use an external HD for both TM and a bootable clone, each should have it's own EHD. The reason being is if the EHD crashes you have lost ALL of your backup and are dead, don't laugh it happens! To create a bootable clone get either SuperDuper or Carbon Copy Cloner (both about $30) and you're pretty set. Many people on these forums (including myself) use that strategy and yes I have had a backup fail.

Can i upgrade my iphone 4 unlocked from ATNT and currently on iOS 5.1.1 to latest iOS 6 coming with iphone 5 without locking the phone again.

If it was officially unlocked by AT&T, it will remain unlocked during an upgrade of the iOS. If it was hacked to provide unlocking, it will most likely lock to the original carrier.
