[OS X TeX] TeXShop cannot be opened

[Murray Eisenberg]

I’m asking this for a colleague who just downloaded MacTeX-2017 to a brand new Mac that is running macOS Sierra (10.12.5).

He writes:

  "I successfully downloaded the MacTeX.pkg, the md5 command verified that the MacTeX.pkg  was undamaged. Unfortunately, when I tried to launch the program I rec’d  the error message: 'TeXShop  cannot be opened because of a problem. Check with the developer to make sure TeXShop works with this version of macOS’.”

Any idea what could be wrong?
