Hey everyone!
Today I had an issue with my 2012 13' Air running OS X 10.8.1. I only had Safari and Mail open, when suddenly the fans kicked in and the Air started to heat up. I noticed a process in Activity Monitor called 'imagent' which was eating about 30-40% of CPU, and did 'force quit' on it and the Air started to cool down. However I noticed that around 20 GB of my SSD space were gone. This was solved with a reboot.

- Use Time Machine to back up or restore your Mac. If your iCloud Backup couldn’t be completed or you can’t restore, get help. Find out how to manage your iCloud storage to make sure you always have enough space for your iCloud Backup.
I have found many issues like this, 'imagent' process eating CPU and swapping to SSD. But what is this thing? Which app is it connected to? How to prevent it from doing such stuff in the future?
Thanks!

Try booting into Safe mode
<http://support.apple.com/kb/ht1564>
This will not load any 3rd party additions, it will load some more conservative Apple drivers (may cause screen flicker), and it will clear some kernel caches (a cache is saved data in a form that can speed up a program, but is totally redundant to the original source, and thus can be safely cleared). Booting into Safe mode is just an experiment, but can often times eliminate any 3rd party interference, or a cached item out-of-sync with the world.
If you get your system to boot up, then
