Q: Is there a way to upgrade my MacBook?

Read Re: upgrade OSX for MacBook5,2

You don't mention whether you are considering a software (operating system) or hardware upgrade.

The following indicates that you can upgrade the operating system to Mountain Lion or Mavericks:

System requirements for OS X Mountain Lion

OS X Mavericks: System Requirements

The following is one source that has hardware upgrades (memory and hard disk or sad)

And while I was researching for my response, Allan likely came up with a better answer!

Leopard is 10.5

Snow Leopard is 10.6

So which do you have?

You can updating till 10.6.8.

If you have very many older applications you use and would like to continue to do so,

be sure the Snow Leopard installer option to install Rosetta (on initial SL install) is

checked so that will be installed; this helps some older applications to run in 10.6.

From the  Apple servers, there is a final update 10.6.8 combo; run Software Update

from the installed and running Snow Leopard 10.6, in the computer, to get this Combo.

Or get it direct from Apple at the link below, so any further files for additional update to

Snow Leopard will follow more naturally, with OS X 10.6.8 already running after this:

Information and Download:

•Mac OS X 10.6.8 Update Combo v1.1

Post Date: Jul 25, 2011

File Size: 1.09 GB

After you've installed this update to Snow Leopard, and the computer has restarted

and running in OS X 10.6.8, you should run the Software Update again, to see

what else is available to update the remainder of the final Snow Leopard 10.6.8.

You could also find and run Disk Utility from the booted new OS X version and

check First Aid, where you can run 'Repair Disk Permissions' on the Mac HDD.

There also may be other items such as Adobe Flash player (get from Adobe) that

likely have an update version newer than the years-old 'shipped' version, here:

•Adobe Flash Player - Flash Player Help:

If there are some issues, or to know of more info, there is this Flash Player page

where some of the items look like the above link to Help, but offers additional:

•Installation problems - Flash Player - Mac OS X:

There are pages in Apple Support online that offer more information, user guides

and a rather large database that may be of help, with this OS X upgrade & more.

You may be able to get a later version of iLife and iWork, etc that are newer than

older versions of that software, but read up on iLife since some older versions

are more desired, and some have limits as to what OS X supports them.

Good luck & happy computing!

Oh, just rediscovered in my Bookmarks this link that may be helpful

and I checked, too, and saw this link to Support still works...

•iLife: System requirements

There are links within it to older iLife versions, and a starting point

should one wish to look for copies of older iLife versions online,

at places such as amazon affiliate stores, and other recyclers.

Hopefully it may help some, should you go there.

Good luck & happy computing!
