Here we are OSX 10.5.6, a huge update of almost 400 MB, after update, when i open Logic it rescan partition 6 and 7 and install something before it open. It look that everything work good when reopening previous file, tried to see in Apple site the explanation detail of this update they not appear for now

Thanks for the info! So, in your opinion, are things working "better" than before? Do you notice any changes, e.g. cpu usage being lower etc...? Cheers Rounik
