Answer 1

no no no..
Calibre enabes you to REFORMAT books of one file type to other file types.
It also strips DRM from purchased books you download... DRM is a security package around a file,, like an envelope around a letter. with steel instead of paper..
Calibre enables you to STRIP- aka REMOVE the drm format so you can read it in it's real format..
So.. you buy a book through google bookstore, or powells dot com and it arrives with the DRM, which is just a security package around the epub fomat. You can then OPEN and read it usng FREE: adobe digital editions.
BY using FREE calibre..
HOWEVER,
for your MBP, or any phone device ..you can also FORMAT the book by using Calibre, to a PDF. ( or other formats..)
AND read it yourself, or have it read to you..
so.
1. get the book.. and HOLD onto it.
2. get CALIBRE;, then use method 3 in this UrL where it says:
Method 3: Use Calibre Plugins to Remove DRM from ePUB
at:
http://www.epubee.com/remove-drm-from-epub-on-adobe.html
TO INSTALL Calibre correctly...
3. THEN GET ADOBE DIITAL EDITIONS at this url:
ww.adobe.com/products/digitaleditions/#fp
4. THEN open your DOWNLOADED BOOK Iusing  ADOBE DIGIATL EDITIONS.. and it will..then just close ADE...(apple Q)
5. THEN OPEN CALIBRE, and follow METHOD 3 to the file of the download in your ADOBE DIGITAL EDDITIONS files,, in your library on your comp....
6. IT will OPEN the file- (the same book file you just closed using ADE...)
and then...
7. CONVERT it to PDF,,,(or what ever,, kindle or which ever file kind you want.. the little dial on the right spins,,,, and WALA you will see it add the new file format extension on the eright hand / mid way down side of your screen next to BOOKNAME BLABLA, EPUB- PDF..xyz format
NOW you have a pdf version..
next..
8 GO get acrobat reader from Adobe,,, either staright up or through app store,,it's free,,,:
http://www.adobe.com/support/downloads/product.jsp?platform=macintosh&product=10
and you can OPEN your pdf version of your book, and read it using acrobat reader,  or preview,, and if you use acrobat, in the menu settings uptop one of them, says read me the pagge, and under that it says read me the entire book,,, so after all that work, you can have the story read to you if you are to wiped out to read it ..lol,,
or get the PHONE version if you want it on an ipdad or iphone,,,this is different version than MBP, or MBA would use,,, ( there is a pro version for iphone.ipad out there too..)
