Im buying a new 13" Pro within the next week, and I have been reading on the heating issue. We have a 30day return period where you can return the device if you dont like it. Im wondering, how can I test if the Mac I`m getting is not one of those that are prone to overheating? My use is dominantly web surfing (10-15 pages at once), watching movies that are streamed, youtube, spotify, dvds from the library.. perhaps some old games. Half-life 2 etc.. Can I stress test it in some ways to find out if its easily overheated?
