My apologies up front if this is a dumb question. I am new to Mac (3 months) and still uncertain about a lot of things. As an example: Can I safely drag GarageBand to the trash without affecting anything else on the computer? What about other Apple applications that I will never use? During my 15+ years experience with Windows I learned to keep my computer as simple as possible, retaining only those applications that I needed . . . never allowing useless clutter on the computer. With that said, I have to comment that I never once saw the so-called "Blue Screen of Death" on my Windows computer. Given my past experience, my natural inclination is to keep this iMac as simple as possible, but (as Einstein once said) "not too simple."
