can any one suggest what to do. I have the latest logic and os for mac and it has stopped giving me the option of a 64 bit start up I have installed Reason 5 duo, the complete spectrasonics team and melodyne recently and I dont think they can disable that option in logic ? I open my applications window , choose get info and where the option to choose 64 bit,used to be, has now got open using rosetta instead. What have i done?

Hi Mark h, When you get Info on the Logic app what version do you see in the Get Info window? Check that you're "Getting Info" on the correct version of Logic in the Applications folder. The most up to date version should simply be called "Logic Pro" and not "Logic Pro 9.x.x". HTH Rounik

Thank you Rounik You are spot on right , I am an idiot!!!!! I had been pulling my hair out for weeks on that one thanks so much!!!!!!

No problem Mark! It can be a bit confusing though! I often move the older versions of Logic (with numbers to indicate their version number) to a separate folder. :) R
