    Hi guys,
    I found after upgrading to El Capitan that I cannot use some of my Nikon software (View NX2 & Capture NX2) and decided to switch back to Mavericks. Unfortunately before realizing this, I had bull dozed the Mavericks back up with El Capitan back up (don't ask my why). However I didn't know that Migration Assistant cannot retrieve the data from drives with more recent osx. So I manually transferred the data and downloaded all the apps. However the only problem is with the apps purchased from Apple App Store. All those apps are showing installed and 'greyed out' and I am unable to download again (Temperature gauge, Blackmagic Speed test, Logitech camera settings, Evernote, mp3TrueEdit, Pages, Numbers, Keynote, iMovie).

    I'll appreciate if you could help downloading those apps. Should I just copy/paste those apps from El Capitan application folder?

    Remove the El Capitan apps from your computer altogether, then redownload them; many of the apps need to be backdated to work with Mavericks. If you have an external drive that has those apps on it, disconnect that disk from your computer before running the App Store. Then, check the "Purchases" section for your apps in the App Store, then redownload them.
    Note that Nikon says that Capture NX2 will work with El Capitan as long as it's installed before upgrading to 10.11, and if you're on version 2.4.7. Nikon also says View NX2 version 2.10.3 works. Source:
