1. Will upgrading to yosemite on macbook pro late 2011 cause my itunes library to erase?
2. Will upgrading to Yosemite repair a sound glitch issue that occurred after I installed Boom. (Boom has been properly uninstalled but the glitch is still there - tinny etc.
3. If I reinstall the operating system, will I lose itunes library?
4. Can one resinstall the operating system oneself without a disk?
5. I want to remove my HD and put in a 1 TB HD and put the contents of old onto the new. I know how to do this, but will I be able to put the operating system into it myself without a disk?
Operating system is 10.8.5 mountain lion
Thanks for answering.
