I downloaded Spec Ops: The Line back in March 03, 2016, and was able to play the game on my MacBook Air. Then I had removed it because of storage space. Since then I had downloaded Mac Sierra and am now running on macOS Sierra version 10.12.2. I tried redownloading Spec Ops: The Line and was able to download it, but when I tried to launch and play the game, I was unable to and I uninstalled it and re-downloaded it but was still unable to launch and play.
Why Won't Spec Ops: The Line Launch after downloading?
User-centric queries such as this are perhaps best put to Apple's public community support forums, where Apple tends to monitor user comments, and/or Apple's twitter support account, vs. risking off-topic here in the dev forums, thanks and good luck.
