I have an older iMac ( 2008 ) running the latest version of El Capitan and today Logic Express 9 keeps closing down the instant I try to bounce or import a file. I've reinstalled the whole programme from my original discs and it's still the same. I also have it on my Mac book and that works all ok......I am baffled!....
