Many thanks for all the help, and advice. Can confirm went back to my old iMac and removed old versions of Wine and HC Launcher (had to do this as using Launchcat with a newer version of wine already installed caused Launchcat to enter an infinite loop of downloading Wine - incase that's useful feedback for anyone - used Appzapper to make sure everything was gone) and then using GM Mangas fantastic new install guide (Launchcat) in the Mac Install thread all works fine - thank you all
