I am running iPassword v4 on my iPhone & iPad and v 3.9 on my Mac (from the App Store). It works fine on the IOS devices but not on my Mac. I am running Mountain Lion and Safari 6 and it may be that I will have to wait for v4 to come out. Otherwise now, the safari extension fails to load and the GO&Fill feature will go to the website but does not fill anything!!
Any suggestions as to how to fix it or is it that the software does not fully work on Mountain Lion?
