I have a mac book pro and recently downloaded i photo how do I upload apps to my ipad mini?

You can't. The Mac versions of the software will be different than the Apps for iDevices. You will need to purchase the iOS version separately.

You could never run iOS programs on any computer. You could never run any Mac or Windows programs on an iOS device. The operating systems are different, and each can only run compatible programs. This has been fact since the beginning of computing.
