How do I upgrade 10.5.8 to leopard or snow leopard?

To get information about your Mac click the apple (screen top left) and select About this Mac. This will give you your OS number. Then click More Info to see which Processor you have. If it says PowerPC you cannot upgrade to Snow Leopard and above as they are Intel only. You can discover more about various Macs at: http://www.apple-history.com/
The OS numbers and names are:
OS X 10.4.x - Tiger
OS X 10.5.x - Leopard
OS X 10.6.x - Snow Leopard
OS X 10.7.x - Lion
OS X 10.8.x - Mountain Lion
If you have an Intel Mac it is well worth upgrading to Snow Leopard now and then considering other options after that.
You can buy Snow Leopard here:
http://store.apple.com/us/product/MC573Z/A
For details about upgrading this to Lion or Mountain Lion see:
http://store.apple.com/us/product/MD256Z/A
In each case check that your Mac complies with the requirements.
If you are not in the US you should use the Change Country link at the bottom of the page.

If I have OS X 10.5.8 installed, how do I upgrade to Mountain Lion? Do I need Snow Leopard first?

I have a MacBook Pro from 2008, and I would like to install Mountain Lion, but I currently have 10.5.8 (which I think is Tiger?). Do I need Snow Leopard first in order to get Mountain Lion? Where can I buy Mountain Lion (since I can't get Mac App Store with my current OS...

You'll need to purchase Snow Leopard (10.6) from the Apple Store before you can use the App Store application.

How do I upgrade Leopard to snow leopard

How do I upgrade my Leopard to snow leopard since Apple no longer supports it.

Apple sells it, they just do not advertise it.
Call 1-800-MY-APPLE. $19 for single-user disk, $29 for 5-user disk.
Make a good backup or clone (I prefer the clone) before upgrading.

I've read similar questions and answers, but I am still terrified to upgrade from leopard to snow leopard. The only reason I want to is because I received an iPad which requires an updated system. I have an external hard drive. I have the disks to upgrade

I've read similar questions and have studied the answers, but I am still terrified to upgrade from leopard to snow leopard on my macbook pro. The only reason for doing it is in order to sync my macbook pro with my iPad. I do have an external drive which automatically backs up every hour. BUT.......I am techno-ignorant as well as techno-paranoid. I have the disks to update to snow leopard but knowing doing so may likely change/alter/lose/obliterate my current set-up, it actually makes me feel sick to think of it.
Years ago when updating via Apple Protection Plan tech support, my screen actually went blank, everything gone! The tech told me not to worry, that "we" would be able to restore things, but several hours later I was still looking at a primitive looking screen that wasn't anything like what I had before. His language was too technical, in that there was an assumption I understood things I had zero understanding of. Example: partition my external drive.
Anyway, living hundreds of miles from an Apple service provider, and no Apple techs in my community, I had to wait for a trip to an Apple Store where one of the wonderful guys at the genius bar spent a ton of time getting things back to normal and actually explaining it enough that I had a vague understanding.
So now I am in the predicament again and won't know what to do after installing the new disks and finding a likely mess or absence of documents etc. on my computer. I don't know how to access the external drive, and even if I did I wouldn't know how to move stuff from that to my computer.
Anyone have any suggestions?

I'm in the same boat as you, I've used Mac's since day one and neglected my Windows education and now it has come to haunt me as I have to learn it like a school kid.
Nearly 99% of all businesses and nearly 95% of everyone use Windows, Steve Jobs declared "The desktop wars are over, Microsoft won" a long time ago.
By 2015 tablets are going to be selling to consumers more than traditional computers, your living proof, you got a iPad.
Apple has already discontinued the Xserver, the Xraid, the MacBooks and the 17" Macbook Pro.
Apple has introduced BootCamp in OS X 10.6 and up, this allows a partition and drivers so one can install Windows on a Mac.
https://www.apple.com/support/bootcamp/
Why do you think they named it "BootCamp"
You can't run a older OS X version longterm like you have with 10.5 anymore, Mac's are being targeted for attacks and older OS X versions are dropped for security updates.
In fact your Mac might still be part of the 750,000 Mac strong Flashback botnet or infected.
https://en.wikipedia.org/wiki/Trojan_BackDoor.Flashback
http://arstechnica.com/apple/2012/04/how-to-check-forand-get-rid-ofa-mac-flashba ck-infection/
See here, Apple has no security updates for 10.5 users and soon 10.6 is going to be ignored next.
https://support.apple.com/kb/ht1222
1-1.5 years is the OS X upgrade cycle. Change everytime like it or not.
So I'm thinking about your long term future and how you obviously don't like change, need local assistance like it appears you first claimed.
So buy a new Mac and upgrade your OS X version whenever Apple shows it in AppStore.
When your machine can no longer upgrade to the newest OS X version, then you've got about another 2 more years of security updates before you have to buy a new machine or risk running a insecure one.
Learn here how to go about fixing your own machine and creating backups/bootable clones this way your not having to drive several hundred miles for a software or boot drive repair. Simply reverse clone your troubles away.
Most commonly used backup methods
https://discussions.apple.com/community/notebooks/macbook_pro?view=documents
I'm of the maturity and experience that I know a Mac isn't always the best solution for everyone and even Apple doesn't provide the proper hardware, support or features for everyone. Why only store locations in high traffic ritzy areas?
Our SteveJobs fan here is under 18 years old with good eyes, he's not older like we are with bad or failing eyesight.
The new Mac's have hard to see glossy screens and the type/UI can't be scaled up easily to accomadate our older eyes, however a Windows 7 machine does allow up to 150% scale of the UI, type etc., and also there are anti-glare screen PC's and just about no more anti-glare screen Mac's.
I wrote this User tip in case you have trouble seeing the screen, at least you can scale the web browsing up
Web browsing for hard of seeing users
Apple might still be selling the anti-glare 15" non-retina on their online store, it's the "high resolution/anti-glare model"
But I can get a 17" 1080i HD anti-glare Windows 7 laptop at Sager for a lot more performance and screen size for the price than a Mac.
https://www.sagernotebook.com/index.php?page=category_browse&selected_cat=2
Screen size is important as the UI and text can be scaled up for easier reading.
Of course you do now have the option of having Windows pre-installed alongside OS X to begin your transition to the dark side.
Just call and they will accomondate, hold the option/alt key at boot time to swtich operating systems.

Windows 7 looks just as good as OS X, the secret is having a good monitor with most PC's come with don't.
Good Luck and I hope I've given you a lot to think about.

I have a hdd from late 2009 that I upgraded from leopard to snow leopard to lion to mountain lion. I want to upgrade the hdd to ssd. Do I need to buy a new copy of mountain lion to install on the ssd? If not, then what is the procedure to transfer?

I have a hdd from a late 2009 mbp. I upgraded from leopard to snow leopard to lion to mountain lion. Now I want to upgrade to a ssd. Do I need to purchase a new copy of mountain lion to go on my new ssd? If I don't, then what is the procedure to transfer mountain lion with my 4 user accounts onto the new ssd from the hdd?
I'm confused on if I can use the recovery hd on a thumb drive to install mountain lion on my ssd. Will it be pheasible with so many OS X upgrades? And then how do I get my user accounts onto the ssd from the hdd. Do I use migration assistant? Do I need to make a time machine backup first? Should I use something called Carbon Clone or something like that?
Thanks for reading

If you have a cable that connects and external HDD to the MBP, it will do. If it is something like this, an enclosure will not be needed for the swap:
An enclosure allows you to use your old HDD for storage or backup purposes. The cable will not.
Here are instructions as to how the swap can be performed using DISK UTITY. Substitute You cable for the enclosure in same:
INSTALLING A NEW HDD IN A MBP
1. Make certain that you have backed up all of your important data.
2. You will need a HDD enclosure. One with a USB connection will do. A 9 pin Firewire is better.
3. Install your new drive in the enclosure and connect it to your MBP.
4. Open DISK UTILITY>ERASE. From the left hand column drag the new drive into the 'Name' field. Make sure that the format is 'Mac OS Extended (Journaled)'. Click on the 'Erase' button.
5. Click on the 'Restore' button (on top). Drag the old drive into the 'Source' field and the new drive into the 'Destination' field. Click on the 'Restore' button on the bottom right hand corner.
Depending upon the amount of data you are transferring, this may take a couple hours or more. A Firewire will speed up the transfer. This will result in both drives having identical information on them.
6. After the data transfer has completed, you may swap the drives. Start the MBP and you have finished the installation. The initial boot may take a bit longer than you are accustomed to, but that is normal.
7. When you are satisfied that the new hard drive if functioning properly, you can erase the old drive and use it for any needs that you may have.
If there is any confusion on your part, post back.
Ciao.

Upgrade leopard to snow leopard with preexisiting snow leopard time machine backup

I was using an old desktop Mac that had been upgraded to snow leopard from leopard a few years ago. Disk utility said I needed to repair my hard drive using the installation discs. I didn't have the snow leopard installation disc but still had the leopard installation disc which I used. When the computer re-installed leopard onto my hard drive, it created a partition: one with my hard drive running snow leopard, and then a new one with the space left over, running leopard. I got my replacement snow leopard installation discs and would like to delete the leopard partition, and go back to what I had before with the snow leopard drive. I do have a time machine backup (somewhat incomplete) and am making a copy of the physical snow leopard drive. I cannot access the most recent time machine backup since I'm back to running leopard and the time machine backup was made under snow leopard. I'm not sure how to proceed from here to upgrade to snow leopard. When I try to upgrade to snow leopard, I'm asked which destination drive to use. I don't want to use the snow leopard drive, since it would get deleted. So, would the leopard drive be the answer in this case? And what would happen to the contents of my old snow leopard drive? Would I end up with two partitions, both with snow leopard, but one being current (nothing on it) and the other being my old drive? Would I be able to get rid of the current drive and then use only my old drive? Thanks in advance for any help.

First of all, it's unclear to me why you cannot select the old Snow Leopard partition.
I also think you should have been able to repair hard disk using the leopard CD disk without actually installing leopard OSX by using the Utilities only.
Also, Why is your Time Machine backup incomplete? Is that under Leopard or Snow Leopard?
Now you have two partitions with two different OSX (Leopard and Snow Leopard). Your goal is to get back to Snow Leopard.
I going to assume that the original Snow Leopard partition is inoperable (this is also question?) I would upgrade the Leopard partition to Snow Leopard. Afetrwards, use the Migration Assistant to bring in your data, documents, app, and settings. Once complete, you should be able to see your Time Machine backups. If all is ok then you can delete the original Snow Leopard partition.
This is a somewhat complicated situation, so I am issuing a caveat that is my opinion only. Wait until another expert provides input regarding your situation to determine the best course of action.

How do I partition my MacBook Pro so I can keep Snow Leopard and also install Mountain Lion?

How do I partition my MacBook Pro so I can keep Snow Leopard and also install Mountain Lion?
I want to install the latest OS, but I already know that I will lose a lot of my software unless I can partition the hard drive and have two "bootable" drives.
How do I retain everything I have, partition the drive, then reloa the software I own according to which OS it will work under?

I do not currently own OS X ML.
I am currently running OS X (10.6.8 Snow Leopard) on my MacBook Pro. It has a 2.8GHz Intel Core 2 Duo Processor. I want to upgrade to Mountain Lion, but many of my software titles will not operate with ML and I cannot afford to replace some of them (Adobe Creative Suite, for e.g.)
After I back-up my HD and then partition the HD, how do I use the back-up to reinstall what I want to the SL partition, and then place the rest on the ML partition.
I have not done what you want to do, so can only offer some general thoughts in support. Take value from the following where you can. No guarantees.
If it was me, I would use a disk clone utility (e.g. Carbon Copy Cloner) to image the existing Snow Leopard disk to an external drive. Then verify that the external drive would boot and run Snow Leopard normally.
I would then purchase and download the Mountain Lion upgrade installer, but not run it. Use Lion Diskmaker to make a bootable USB stick, and perform a clean install of Mountain Lion, replacing the Snow Leopard on your MBP. This way, you make absolutely certain that no third-party drivers or other SL cruft remains to make Mountain Lion unstable. Update to latest ML point release. Fix permissions. Let TimeMachine make a full backup of your ML installation to a different external drive. Then turn of Time Machine.
In Disk Utility, use the + sign at the bottom of the ML partition to add another GUID, HFS+ Journaled partition for Snow Leopard. Resize to taste. Name it differently from your ML partition. Exhale.
Now ideally, you would like to reverse the external clone and put it back into the new SL partition. Then fix permissions. And demonstrate that you can boot into individually stable OS X installations. This would save you alot of work. Resist copying your home directory into ML just yet.
If you cannot successfully achieve the preceding paragraph, you will be faced with a full SL and application reinstall.
The ~/Library contents for SL and ML are sufficiently different that you do not want to mix them. You may want to salvage Safari bookmarks.plist. And, ML created folders in the home directory may have different permissions or ACL settings than in SL. So, my rule of thumb would be to copy folders that you created in SL, and only the contents of matching named OS created folders such as Music, Pictures, Downloads, etc.
For each operating system, you probably want the Time Machine settings to exclude the opposite OS X partition. If you use the same host name in Sharing prefs, then you will mix SL and ML backups on the same Time Machine back up drive. If you use different host names, they will be distinct folders in the Time Machine backups.backupdb and allow discrete restores per host. You may also want to gag Spotlight from indexing the opposite OS X partition.

Why can't I upgrade to yosemite? I'm currently running snow leopard on my white macbook.

Why can't I upgrade to yosemite? I'm currently running snow leopard on my white macbook.

White MacBooks are NOT eligible to upgrade to either 10.8 Mounain Lion, 10.9 Mavericks or 10.10 Yosemite.
You maybe able to upgrade your white MacBook to OS X 10.7 Lion
OS X Lion system requirements
To use Lion, make sure your computer has the following:
An Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
Mac OS X v10.6.6 or later to install via the Mac App Store (v10.6.8 recommended)
7 GB of available disk space
2 GB of RAM
You can purchase a OS X 10.7 Download code here.
http://store.apple.com/us/product/D6106Z/A/os-x-lion
Before embarking on a major OS upgrade, it would be wise, advisable and very prudent if you backup your current system to an external connected and Mac formatted Flash drive OR externally connected USB, Thunderbolt or FireWire 800, Mac formatted hard drive. Then, use either OS X Time Machine app to backup your entire system to the external drive OR purchase, install and use a data cloning app, like CarbonCopyCloner or SuperDuper, to make an exact and bootable copy (clone) of your entire Mac's internal hard drive. This step is really needed in case something goes wrong with the install of the new OS or you simply do not like the new OS, you have a very easy way/procedure to return your Mac to its former working state.
Next,
If you run any older Mac software from the earlier PowerPC Macs, then none of this software will work with the newer OS X versions (10.7 and onward). OS X Snow Leopard had a magical and invisible PowerPC emulation application, called Rosetta, that worked seamlessly in the background that still allowed older PowerPC coded software to still operate in a Intel CPU Mac.
The use of Rosetta ended with OS X Snow Leopard as the Rosetta application was licensed to Apple, from a software company called Transitive, which got bought out, I believe, by IBM and Appe could no longer secure their rights to continue to use Rosetta in later versions of OS X.
So, you would need to check to see if you have software on your Mac that maybe older than, say, 2006 or older.
Also, check for app compatibilty here.
http://roaringapps.com/
If you have any commercial antivirus installed and/or hard drive cleaning apps installed on your Mac, like MacKeeper, CleanMyMac, TuneUpMyMac, MacCleanse, etc. now would be a good time to completely uninstall this apps by doing a Google search to learn how to properly uninstall these types of apps.
These types of apps will only cause your Mac issues later after the install of the new OS X version and you will have to completely uninstall these types of apps later.
Once you have determined all of this, you should be able download OS X 10.7 Luon from the Mac App Store icon in the OS X Dock and then login to the Mac App Store using your Apple ID and password.
You can then begin the download and installation process by using the paid download code to Download and install OS X 10.7 Lion rom the Mac App Store.
Good Luck!

You are already running Snow Leopard. To upgrade further:
Upgrading from Snow Leopard to Lion or 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 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

Trying to upgrade from leopard to snow leopard

Trying to upgrade from leopard to snow leopard but now cannot use keyboard to boot from DVD (holding C key) or even from external drive (holding option key)
Is there any other way that I can force my mac to boot from external drive. Please help

Hi Cattus
In reply to your answer - external drive is GUID partition and has worked on my other Macbook in upgrading from leopard to snow leopard. So I know the external drive does work.
I have tried DVD and external drive on good Macbook and all works fine back on problem Macbook no luck. I don't even get firmware password request. Keys on keyboard do not work at all. Tried to boot in single mode (cmd S) as well as target drive (T key) but no luck whatsoever.
External drive is USB and working. Problem Macbook did show signs of not good functioning keyboard with certain keys not working whilst still under Mac OS 10.5.8.
Do you know how to get around this problem? Would I need to remove drive from Macbook and resolve it as a stand alone drive?
Thanks
