Due to space restrictions, I'm not able to set up my desk/workspace in our flat, so it's all going out in the garage. The temp is mild there most of the day, never gets too hot, but I'm worried about keeping the macbook out there overnight. I left it out there one night, and the metal was very cold to the touch. Right now it probably doesn't get below 4 C (about 40 F) at night, and it's usually closer to 10 C (50 F). In the winter it probably occasionally drops down to freezing. I'm sure the cold isn't great for the battery, anyone have any ideas about other components that might have problems? Except for the battery, is it ok to leave out there? Thanks!
