    Thanks, very interesting.

    I've already updated my Mac Pro 8 Core but didn't tested it yet. I am curious if it affects my machine, too ! Would be very disappointing....

    Are 09 Quad Cores the only machines affected yet?

    Does this affect the Logic Express update too?

    HyperThreading can help, but it's not exactly a 2x speed up in any way. So I find those reports a little odd.

    As far as I heard, it's the same thing.

    Fix for 9.12

    Fix for 9.12.

    Open terminal:

    Enter this string:
    defaults write com.apple.logic.pro MD_AllowVirtualCores -bool yes

    Your hyperthreading is re-enabled.

    On my Corei7 2.8 ghz iMac I went from 61 tracks with HT with 9.11 to a pitiful 30 tracks!

    With 9.12 and the fix I went to 70 tracks!

    This is using the Evan benchmark where every track has a space designer and exs1 instrument. Overkill I know. No real session would ever have that.

    At any rate, there you go.
