I came across very strange iCloud behavior. I've been running my MM account for a several years now and I want to keep it 'till Apple completely stops to support it next year. At the same time I want to try iCloud thing and I registered completely new iCloud account today from my iPad. I got all today's updates (10.7.2, iOS5 and latest iTunes) and came across very strange iCloud behavior. On my 2010 mac pro I was able to login into iCloud keeping my MM account running simultaneously both look to coexist very well so far. But when I tried to do the same thing on my 2010 MacBook Pro it didn't work. I can log into iCloud OR into MM but not into both. That's seems very strange since both machines are running the same OS with pretty much the same sets of software. What might be the problem? Any clue? Thanks!
