Hi, Can I 1. Download for hours on the Mac? (whats the max time I can?) 2. Leave it on sleep for days? (whats the max time I can?) In order not to ruin or burn out anything inside. (or even make less efficient) I have an alternative which is my windows Desktop. But I don't want to download my movies there and transfer everyday. So how long can I leave it on/ sleep such that the MBP 13inch isn't harmed in ANY way. Thanks.
