Can i update to ios 7 if i am using a macbook 5,1 that runs iTunes 10.6.3?

Question

my macbook is the 5,1 model and i know it's running on outdated software, but i am unable to afford the software update at this time. i have an iphone 4s and i haven't had any issues performing software updates in the past with this computer. i would download ios 7 over wifi, but the wifi option on my iphone is permanently grayed out, as a result of downloading ios 6 (i have already tried restoring, didn't work). i am unable to update my iTunes, as a result of the os on this computer being outdated. again, i am running itunes 10.6.3, i think. itunes recognizes that ios 7 is available for download when i plug in my iphone, but  when i click on the "Update" button, a box saying "This version of iTunes (10.6.3) is the current version." comes up.

Answer 1

Well, you have to minimally upgrade to Snow Leopard 10.6.8:
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.
But this costs money, so you can't do it. That means your are stuck where you are.
