Hello guys. I had the MX-450 but I'm on a Mac computer so cannot use the software to update the remote. Anybody have any ideas which codes are the best choice for the VSX–1123 Pioneer receiver? I only wish they had software for a Mac. I've had the remote since 2010. I used to have the software installed on virtual machine until about two years ago which was the last update the remote got. Unfortunately I don't have virtual software anymore to run the software. Any information is greatly appreciated.
