it was mentioned by "greatinterface" that logic may not function properly playing audio if you have more than 1gb of ram installed
I had observed the same error + had thought it was just a bad cracked copy of logic but apparently removing ram and being at 1gb exactly or under
will make logic function normally!!
amazing information, i was trying all summer to get this to work.. ( u can see in the comments of the above download link on the macintosh garden how crazy i was going not understanding why it was working for a little while + then would stop working...!!!! and it was all becuase of being over 1gb of ram!)
and the machine had 1.12gb of ram somehow from the combination of ram sticks..
thank u greatinterface for this information!!
