Maybe just paranoid... Since sleeping (it is all safe sleep now, right?) the Mac writes all all the contents of the RAM to HDD (correct me if I am wrong), does making it sleep repeatedly harm the Mac in any way? Does this massive writing of data harm the hard drive? When I move my MacBook Pro from my position at a chair to a table, is it better to put it to sleep and wake it up once I reach the table, or just carry it with care to avoid sudden movements? Sorry, because I have really little knowledge regarding this. Thanks for your replies.
