title: Writing an installer with choose folder option in osx
body: <p>I am writing an installer for plugin to Adobe photoshop in mac os. So, when I googled I could find that installer for mac os is coming in two formats;dmg and pkg. 
   In dmg there is no option to ask the user to select the folder location of the software(Adobe photoshop in this case). This is required to place the plugin files in the adobe photoshop software location. 
   Whereas in pkg, there is option to ask only to the hard drive level and not to the folder location level( I might be wrong here. Please correct me if I am wrong).</p>
  
  <p>Applescript might solve the problem, but I need to include a license agreement for the customer to accept it and then proceed with the installation, which made me not to select applescript</p>
  
  <p>Please help me to solve this issue and suggest a approach. </p>
