Is there music recording equipment that you can plug into your Mac?

My boyfriend's birthday is coming up and I'd love some help. He plays the guitar and is a songwriter, but only uses his iPhone or photo booth for the recordings.

Is there some sort of music device out there that would allow him to plug a guitar and a mic into his Mac and create a high quality mp3? He plays in a band with one other musician so if they could both plug in their guitars that would be amazing.

I tried to buy something off of ebay, and i have a problem?

I tried to buy an iPhone 4S case for my phone and you know when the payment options come up?
i put in my card info to complete the payment. But when i tried to click that "pay" button it said it was authorizing my payment, but it just went back to that payment page and at the top it said "payment was not processed, issue with card holder" or something like that. And when i went to check my account online it said that the money was taken out of my account 3 times, and when i tried to look at where my purchase history was, it didn't say the phone case was being shipped at all. My bank account was put on hold because of that and all my money was taken out of my account when it shouldn't have been. What can i do to get my money back from the seller? Report the seller or what?

After iOS 7.1.1 update on my iphone 5c I can't connect to app store or itunes store?

I noticed it happened to me after I downloaded a gameboy emulator. In order to download it I had to set the date on my phone back to feb 10 2014. I'm not sure why they ask for that but it doesn't download unless I do it. Could that be my problem?

I tried re signing in to my apple account on the phone and it said can't connect to itunes. I tried restarting my phone, nothing changed. All the other apps work fine. (Safari, youtube, mail, etc.) Wi-Fi is on.

I did notice that I can't use imessage either.

All together I think the problem is I can't sign in to my apple account

What's wrong with my icloud?

I have a iPhone 5s and it kept popping up that I was almost out of data in it. I have 5gb storage but it says I need an additional 2.4 to back up. I managed my settings to what goes on there and I only have my photos on it and it is only 2.6 gb and besides that I have nothing on it. Where is the additional gb coming from.
