***This is a workaround and may not apply in later OSX updates or new operating systems that Apple pushes out***
- Go to the app store account page and make sure you are signed in
- Click on the Launchpad icon on your MAC and find the apps that need the update
- Click and hold the app until it wobbles....like it does on your iPad or iPhone when deleting apps
- Click the X by the app to delete it
- Do this for all of the apps that need an update
- Close Launchpad
- Wait about a minute or two then click the update/cloud download icon for the app in the app store
