Mavericks & Logic X
OK.... my test...
Mavericks dual monitor set-up is sluggish!
When i display a movie on my second monitor its "Stuttering" also the menubar remains visible (Thats not nice looking),
Switching back to OSX 10.8.5 the problem is gone......
Also the TAB system in the Finder is not as nice as third party Finder apps.
Moom is not working anymore...... Moom is much nicer as the finder window in Mavaricks.
There is absolutely no point in switching to Mavericks... i deleted it and switched back to a much smoother working OSX 10.8.5 !! Bad Job....
