Double click extraction didn't work.

[rccharles]

Attempting to install on Mac OS 10.10.5
Downloaded dmg file from: https://sourceforge.net/projects/exiftool/files/

You can see in the attachment that when I doubled clicked on the dmg file, I got a new folder. 

I doubled clicked on the pkg file, but pkg didn't load as expected.  I got my catchall file expander. 

So There could be something wrong with my mac or the pkg file isn't made correctly.  I included three screen captures as attachments

I think you missed one important system message when you double clicked the pkg inside the dmg. Depending on your OS version and settings you should have gotten a message stating that the application was from an unidentified developer, rejecting install. This is normal.

To install the package anyway, right click the pkg and choose open. You'll then need to provide your admin password as confirmation you really want to run the program and after you have done so, the installer will start as usual. Note that this is the standard macOS Gatekeeper procedure for this type of install (from e.g. small developers).

Hope this helps.

P.S. Instead of downloading from sourceforge you could also have downloaded directly from the "source".

It is a problem with my system.  I installed the "I Spy.app".  It was grabbing the .pkg files types as its own.  Manually, picked the opening app as install.app and exiftool installed.
