Is anyone else discovering that their Retina MBP is running a whole lot hotter with the new OS X? My machine is a 2.6GHz, i7 with 16GB of RAM purchased new in April and since yesterday when I upgraded to Yosemite it's started running really, really hot. Before yesterday the computer never had any heat issues even when running multiple high processing applications. I've even uninstalled Silverlight but watching a Netflix TV show with nothing else open means I now can't have the computer on my lap. Is it just me, should I contact Apple with the issue or are others experiencing the same thing and I could hold out for an update?
