I've installed a new primary SSD drive on my mac, now I'm trying to download a few apps that I've already installed on my previous HD, but app store keeps saying they're already installed. But they are not.

Is there a way to tell Apple's App Store that these apps are not installed?

I've already tried the solution on the thread: App Store thinks apps are installed, but no success.

My old HD is still connected to my MBP, but as slave. If you guys need further info, just ask.

  • What happens if you disconnect the old HD?

Just fixed it. Sorry for the noise, guys.

If you have connected your old hard drive to your Mac, your Mac still sees the programs on the external hard drive and knows that they are still installed. You have a couple of options:

  • Delete the Mac App Store apps from your external drive and then re-download the apps to your new SSD.
  • Drop the apps from your external hard drive onto your new SSD, placing them in the Applications folder.
