I discovered an exciting-looking option in Xamarin studio that is labelled "Create installer package". And sure enough with it ticked I get a .pkg file as well as an .app file in the output directory.
However when I run that .pkg file, although it goes through the steps of installing the .app file (including "writing files" and "The installation was successful" - with a big white on green tick), it doesn't actually put the .app file anywhere. (I do a search on the whole machine and its not there.)
Any suggestions how I could fix this, or what I could be doing wrong?
I notice a small info triangle mentioning Mac store. Does this kind of .pkg only work if it is used through the mac store?
