I know i can go to the apple sign in the top right and click software updates but when i do it says i am up to date even though os x 10.5.8 is not up to date. How can i update? Do i have to switch my settings or do i have to download something from the store? I want to get my computer as up to date as possible. Please help.
MacBook Pro, Mac OS X (10.5.8)
You will need to purchase Snow Leopard (10.6) to upgrade further than 10.5.8. See the link below for specs and requirements.
First, you must purchase Snow Leopard (Mac 10.6) from the Apple Store (online, or local). They will ship you an install disc with 10.6.3. Install the OS, and then go back to Apple.com, and download the 10.6 OS updates until you get to 10.6.8.
Download the 10.6.8 update, and now you have the Mac App Store. Open this app, and purchase Lion (10.7). It will download to your computer (no discs necessary). Or, if you wait a few days, you can skip Lion, and go directly to Mountain Lion (10.8), which is cheaper. After that, you're all up to date.
Not all MacBook Pros work with 10.7 or 10.8.
Here's what works with 10.7:

and 10.8:

If your machine supports it, you can go directly to Lion, bypassing Snow Leopard by either erasing the computer's contents entirely, or attaching an external drive without an operating system, and using the USB Flashdrive version of Lion.
Contrary to what others say 10.6.6 is minimum to install 10.7 without erasing.
Though 10.6.8 is minimum to install 10.8 without erasing.
Backup first
It is always best to have a full bootable backup before you upgrade. If you fail to do this you will be unable to return to this OS if you decide you don't like the new OS. Also there is a slight chance that an install could lose everything on the Mac. The backup must be to an external hard disk. Preferably use Carbon Copy Cloner to make a bootable backup of the whole disk.
Erase before the install
Once you have a bootable backup on an external disk it is best to erase the internal disk with the new installer DVD before you install.
During the install
Preferably do not import any data or preferences from earlier OSs during the install process as this can reintroduce bugs.

Upgrade to Leopard
Those wishing to upgrade to Leopard should be aware that install disks can be expensive unless you contact Apple. Details: http://lowendmac.com/deals/best-os-x-leopard-prices.html Standard Leopard installers impose several hardware limitations including speed and RAM size but all these restrictions can be overcome. Google for details. Leopard works well at 500 MHz with 1 GB of RAM and many happy users have less than this.
Upgrade beyond Leopard
OSs beyond OS X 10.5.8 require an Intel processor. If in doubt check this: Click the apple at the top left of your screen 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. 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

Important
Check that your Mac complies with any requirements. If you are not in the US you should use the Change Country link at the bottom of Apple pages.
Keep in mind that the flash drive with Lion is pretty pricy. You might be better off going for Snow Leopard, straight to Mountain Lion.
