Hi Mac Rumors. I have a 13inch Macbook Pro from mid 2012. I have been running a java program overnight and during the day when I'm not using my laptop. So, my laptop's on pretty much 24/7. I have a picture of everything closed down except XRG and the Activity Monitor. I was wondering if I'd be causing any damage by running this overnight or having my Macbook at a constant usage such as pictured. Thank you. EDIT: I just looked at my XRG again. my uptime is actually 8 days.
