Beta Download Identity
When the Beta version is downloaded (Apple version) it comes in with the same name as the current 4.5 version. This can be confusing especially if you want to run both versions. I think it would be 'beta' to set it up to allow both versions to run on the same computer, which can be done at the present so long as the files are not mixed, but with the Beta running under a different name or alternatively a different coloured banner (this is the PersonalBrian.app file). This applies both to the downloaded file name and to the running programme – sorry not expressed that very well but I think you will get my drift! The Apple installation package is just the same for both versions and there does not seem to be a clear definition between whether the new download will just over-right the existing 4.5 version or look for a new location.
