Hi. I recently purchased the new 2015 Retina Macbook Pro 15" (2.2Ghz i7 Haswell/16GB Ram/256GB Flash) and have a few questions if anyone can help me. 1. The CPU temperature runs around 45-55 degrees under normal use but when put under a bit of strain (downloading) the CPU temps raise up to 90 degrees. Is this normal and is it safe for the processor to hit these temperatures? 2. When changing the battery the magsafe LED is orange - when the battery is full this turns to green. if I leave the power connected I'm guessing the Macbook then uses the mains power instead of the battery - am I right? Thanks in advance.
