Just got my macbook. awesome machine but sometimes the ui lag like hell. Maybe it's just because I am setting it up now as it didn't lag when I tested it at an apple store. Is there any way to know if the cpu i currently throttling and causing the lag? Right now I have dropbox, evernote and photos downloading stuff. Maybe spotlight is indexing as well but this is pretty horrible performance so far... Can dropbox and spotlight do that damage? How can I monitor this and the cpu throttling?
