I have a macbook (white) currently have OS X 10.4.11 but need newer to run a file. Can this particular macbook be upgraded?

All MacBook models can be upgraded at least as far as 10.6.8.

If you are in North America ... you must call them (1-800-MY-APPLE). last I read It is $29 plus tax for family pack and $19 plus tax for the individual use version.

In Europe or otherwise … call your National Apple Helpline. Find it at … http://support.apple.com/kb/HE57

Once you have bought and upgraded you will need to apply the Combo updater for Snow Leopard. Mac OS X 10.6.8 Update Combo v1.1

Remember to repair permissions both before and after each upgrade/update.

You don't need to go through 10.5 to get to 10.6, and you don't need to use the repair permissions function either before or after.
