How can I upgrade from OS X Snow Leopard to OS X Lion?

Well Mt Lion is the latest, but if your machine can't do 10.8, then call Apple via phone and order 10.7
However you really need to do your homework first, as a lot of software and drivers could stop in 10.7, no Rosetta like in 10.6, could cost you plenty.

How can I upgrade from Tiger to Snow Leopard wihout violating EULA while Mac Box Set is no longer available?

I use my original Tiger bought with MacBook Pro. But now so many applications do not support Tiger, so I decided to upgrade to SL.
But required by Apple way to do this with Mac Box Set seems to be impossible. Mac Box Set is no longer available from Apple.
Is upgrading using Snow Leopard disc, which is still in Apple Store, ok?
I will be gratefull for help.

The Mac Box Set includes Mac OS X Snow Leopard, iLife ’09 and iWork ’09. If you just use the SL installer, you don't get the additional apps.

Installing Snow Leopard: What you need to know
http://www.macworld.com/article/142454/2009/08/install_snow_leopard.html
The Snow Leopard box set is no longer available at the Apple Store but may be available by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753). You may also find a box set on eBay.
It's possible that some of your current apps may not work in Snow Leopard. You can check here: Mac OS X 10.6 Snow Leopard Application Compatibility List at http://snowleopard.wikidot.com/

I have purchased RAM several times from Other World Computing and have always been very satisfied with the product and service. They have on-line instructions on how to replace the RAM. OWC has also tested RAM above what Apple states is the maximum. I now have 6GB installed on a machine supposedly limited to 4 GB.

Can I upgrade from Tiger to snow leopard using an external DVD drive

I've been trying to upgrade to Snow Leopard from Tiger but keep nothing happens. I keep getting a grey folder with a question mark on it. Can anyone tell me what this means?

If you have another Mac with Firewire, you can use it's Optical Drive as a big Firewire Optical, put the Install disc in the other Mac, boot the other Mac in to
Target mode...
http://support.apple.com/kb/HT1661
Connect a fw cable, use the Otion key on this one to choose the Install Disc in the other Mac.
Can I install if I make a bootable copy to my firewire external?
Yes, especially if you have a small 5 to 9GB Partition, you can use DU to Restore the Install Disc to that.

How do I upgrade from tiger to snow leopard

I have a 2007 intel based mac book pro 15" that I have not used in a number of years. I want to get it up and running again and right now I have OS X 10.4.11 Tiger. I want to get the newest OS version I can possibly get while upgrading from Tiger 10.4.11. Please help.

ekernan,
you’ll need to purchase the white retail Snow Leopard DVD, install it, and run Software Update to get it to 10.6.8. Once there, you can upgrade to Mavericks if your MacBook Pro meets its other requirements.

Problems upgrading from OS X Snow Leopard to OS X Lion?

Hi, I've just bought OS X Lion but to install it I need to go to the Mac App Store which I can't get on my Mac Book with current OS X Snow Leopard. What do I do pls?

It's in your Applications folder - App Store. If you don't see it then either you aren't running 10.6.8 or you need to reinstall the Mac OS X 10.6.8 Update Combo v1.1 updater.

If I recently (two weeks ago) bought upgrade from 10.6 (Snow Leopard) to 10.7 (Lion) can I upgrade for free to 10.8?

I've already read what http://www.apple.com/osx/uptodate/ says. But it's about new Mac only. So, are there any chances? I made the upgrade by stupid mistake - I've belived that 10.7 is supporting AirPlay Mirroring for Mac.

No, unfortunately you don't qualify for the free upgrade.

Upgraded from TIGER to SNOW LEOPARD

Hello,
How can I uprade from TIGER to SNOW LEOPARD? Do I simply use the upgrade snow leopard to do so? Will that create any instability or issues?
thank you very much.
Alex

Yes, you can upgrade from Tiger to Snow by purchasing the SL DVD. Doing so would only create stability problems if you already have problems, so you should be sure you have a clean system before upgrading. See the following:
System Upgrade and Installation Procedure
Basic Caveats
1. Disconnect all peripherals except the original mouse and keyboard.
2. Quit all applications if this is not an installation from an Installer DVD.
3. The installation process should not be interrupted. If a power outage or other interruption occurs during installation you may have to erase the hard drive and reinstall from scratch.
4. Once the installation begins do not use the computer in any way except to reply to dialog prompts or to restart when the installation is completed. This is especially critical during the installation stage known as "Optimizing the System."
System Update Procedure
A. Repair hard drive and permissions.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.) After DU loads select your OS X volume from the list on the left, click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.1 for Leopard) and/or TechTool Pro (4.6.2 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X. Note that Disk Warrior will not work on Intel Macs.
B. Clone your existing system to an external Firewire drive.
How to Clone Using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the startup or source volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Drag the startup or source volume to the Source entry field.
5. Select the backup or destination volume from the leftside list and drag it to the Destination entry field.
6. Check the box to Erase Destination. Skip this step if you've already formatted the drive.
7. Double-check you got it right, then click on the Restore button.
C. Decide upon an installation option (This does not apply to Snow Leopard.)
You have three upgrade options. If you use the Upgrade installation option be sure you have repaired the hard drive and permissions first and made your backup. If you choose the Archive and Install option then you only need to repair the hard drive.
Neither of the above options will erase the disk. Some of your software may not work with a new system. You will need to upgrade those programs. It would be best to do the upgrades to your software before upgrading to the new system version.
Personally, I would erase the hard drive and do a fresh install of Snow Leopard then use Migration Assistant to migrate your old Home folder from the backup. This may take some extra time but is less likely to have problems that may be the result of an upgrade installation.

How can you upgrade from OS 10.4

How can you upgrade from MAC 10.4.4

Backup your computer.
Buy Snow Leopard.
Boot from Snow Leopard DVD.
Erase the hard drive.
Install Snow Leopard.
To get Snow Leopard:
Upgrading to Snow Leopard
You can 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.
To upgrade further see:
Upgrading from Snow Leopard to Lion or Mountain Lion to Mavericks
To upgrade to Mavericks you must have Snow Leopard 10.6.8, Lion, or Mountain Lion installed. Purchase and download Mavericks (Free) from the App Store. Sign in using your Apple ID. 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?
         See App Compatibility Table — RoaringApps.
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 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.

How can I upgrade from Tiger to Leopard

Hello all, hope you can help me.
I´m running Tiger Last Vers on a white MacBook with 1.83 GHz, 55GB Hd and 2 GB RAM.
The thing is that the iPhone 3gs is running quite well (not last version updated, but at least, it runs) and I recently got an iPhone 4, that is too new for my Tiger.
Thus, needs an upgrade, but the Apple Store only provides the Snow Leopard.
So:
.- Can I upgrade the Tiger to the SnowLeopard directly, buying the OS from the Apple Store?
.- Do I need first to upgrade Tiger to Leopard? If so, how do I do that?
I know the very best option is buying a new Mac, but currently for me it doesn´t make any sense as I only want it to sync my devices...
So, any idea?
It´s been almost 10 days since I got my iPhone 4, and I cannot even start it!
Much appreciated
Regards

#1 Do a complete bootable backup of your drive before upgrading. That way should anything happen you can revert back to the start and try again.

How can I upgrade from Infinity to 56K dial-up?

I have had Infinity for about a month. At first everything was great, 38Mbps. I am about 25m from the cabinet where the optical fibre is terminated so I expected this to be quite consistent.
Seven days ago the speed dropped to about 5Mbps and over the next 12 hours or so dropped even further. The last time I managed to get a download speed measurement I recorded a speed of 28.2Kbps (yes, that is Kilobits). I have not had a speed as low as that in almost 20 years. Currently the BT speed tester is not working, I suspect my speed is too slow for it. The BBC speed tester reports my speed as being 0Mbps.
I have called the BT help line every day since and have been told today that it has finally been escalated to the BT Openreach Engineering Dept. I am told that an engineer will visit me in 3 days time to fix the problem. Why has it taken a week to do this and why can somebody not do something quicker? Is BT Infinity so bad that all the engineers are running around trying to get it to work. People always go on about Microsoft getting customers to test their products, I think BT are doing the same thing with a product which is obviously not suitable for it's task.
This is absolutely awful customer service. Seven days for a succession of "support engineers" a few thousand miles away reading from a prepared script is not my idea of looking after customers.
I cannot express how this has changed my opinion of BT.
A few years ago I worked for a major supplier of satellite communications equipment. BT were one of our first big customers. We had to jump though so many hoops before we installed the equipment it was unbelievable. The system was tested to death before it entered service. What has happened to this level of quality control?
To reiterate the subject heading - how can I upgrade from BT Infinity to 56K dial-up?

Hi Satcomman,
Welcome to the forums! I'm sorry to hear of the problems you're having with your speeds. If you could fill out our contact webform (you can find the link in my profile under "about me") and include details of your home network setup, I'll be able to run a few checks and hopefully find out where the problem lies.

How can i upgrade from iphoto 7.1.5 to 8.1.2 on an older iMac running OSX 10.6.8 ?

How can I upgrade from iphoto 7.1.5 to 8.1.2 on an older iMac running OSX 10.6.8 ?

With the above listed config that I have (iphoto 7.1.5 on an older iMac running OSX 10.6.8), how can I move my iPhoto library from this old iMac (2006) to my NEW iMac (2011) that is running iPhoto 9.5.1 ?
To open an iPhoto 7.1.x version in iPhoto '11 you need to run the iPhoto Library Upgrader. See this Support document:
iPhoto '11: About the Library Upgrade
Download and install the upgrader, then run it on your iPhoto 7.1.5 library. After that, iPhoto will be able to open your library and upgrade it to version 9.5.1. And you will be able to merge the libraries with if Library Manager.
