    Hello there,
    I recently updated to yosemite beta 5 and beta 6 at the same time (i've first installed beta 5 and then 6) and after that my macbook is realy sluggish and laggy.
    Som things i've noticed,
    WindowServer consumes like 150-200% of cpu power
    nothing happens when i try to change the brightness on the screen
    the graphics are all laggy and chopy
    and the graphics card does not seem to be recognised because it says it only has 3mb of ram(see picture attached).

    I've tried smc reset but nothing happened. Is there any way to save it or should i reinstall os x?

    Think you might want to repost this in the Yosemite 10.10 forum. You should see it somewhere below the Macbook Pro forum. Also, since Yosemite is releasing to the general public today, many people are still waiting to download the update.
