I have a simple question: today - when starting up my 2009 macbook unibody with lion I saw that there was immediately a large download occurring over my wireless connection. I clicked open iStat to see this process - "ARM" - chewing up about 41% of my 2.4 Core duo processor. Activity monitor has no record of the ARM process and a simple google search takes me to the usual pages about an Apple ARM architecture chip as a potential macbook air successor cpu. Can anyone enlighten me to the nature and purpose of this process on my macbook? Thank you.
