Last month we reported that Google’s slick new “Google+ Photos” app that launched exclusively on the Chromebook Pixel could possibly be making its way to Mac. The proof came from a newly posted listing on the Chrome Web Store that made references to auto-uploading features specifically for OS X. Unfortunately, launching the app would give Mac users a “not supported on this platform” error message. While Google has yet to officially launch the Mac and PC versions of the Chrome app, there is a way to bypass the error message and enable the app now.
Go to the Google+ Photos app Chrome Web Store page.
Right-click the “Add to Chrome” button and select “Inspect Element” (The button will be “Launch App” if you’ve previously attempted to install)
Press CMD + F to enable search in the element inspector and search for “webstore-button-disabled”
Double click the “webstore-button-disabled” text to highlight it in the inspector, delete it, and press Enter.
You’ll now be able to hit the “Add to Chrome” (or “Launch App” button).
Click “Run anyway” when prompted about unsupported platforms.
On Mac, the Google+ Photos Chrome app will instantly upload all .jpg files from the default photos folder located at Mac: /Users/yourname/Pictures.
