The Mac is a great platform. I use a variety of interfaces and software for different applications. As noted earlier, if you don't need the portability, get an iMac. You can expand the memory now or later depending on your situation. If you need portability, the MacBook is great, however, be sure you get as much memory as you can at the outset. Remember, on the retina display models, memory is not expandable (what you order is what you have). I also use an iPad with Garage Band for practicing and sketching ideas. It works well and is more portable than even a MacBook.
If you like Apple software, get Logic in addition to Garage Band. Take a class or two and really learn the program. It's a monster. But identify what you want to do with recording first. Like with all tools, some are better suited to different applications. Logic, ProTools, Ableton, etc., etc., etc., all have their place, strengths, fanboys and detractors so identify what will work best for you.
As far as interfaces, we use Apogee all around. We've tried many in our studios and for the price / performance Apogee can't be beat. I also carry a jam with me for my iPad and use a duet at my home studio.
Good luck. Remember, buy what you want to achieve your goals. Filter the advice you get based on your needs and enjoy the process!
