Non-admin Mac OS X users can't install Pledge in default Applications folder

[aronr]

An access privileges issue that some Mac OS X users might encounter in STEP 1: Install the Pledge software on your smartphone or computer:

If the current user does not have Admin privileges on their Mac, they might encounter an Error! You do not have write permissions to the chosen installation destination dialog, when attempting to install to the default install location: the system-wide Applications folder (/Applications):

As well - possibly as an artifact of the installer? - the user is never presented with the usual OS X dialog that lets them authenticate as an Admin user, in order to install Pledge to /Applications.

We might include installation (or troubleshooting) instructions for instead installing Pledge in an alternative location. Installing Pledge in the user's own Applications folder (/Users/{username}/Applications), could be a suggested best practice.

(A related aside: generally, doing day-to-day work in a non-Admin account is a security-related best practice on a number of OSes. That practice appears to be less common on OS X, albeit one still recommended by some commentators.)
