After a fresh install of macOS Sierra, I installed the macTex distribution without any GUI programs. After that, I installed the latest release of the Tex Live Utility to update my tex distribution via a nice GUI. However, I cannot start the Tex Live Utility because macOS complains about that the program has not been signed by a verified developer. After I tried opening, there is a button under System -> Security to open the program anyway, but I keep going to see the same error message. This worked with another piece of software but with Tex Live Utility, this approach fails. Any idea on how to solve it?

  • You can also try changing that setting to the least restrictive ("Anywhere"? I can't remember exactly what it says) temporarily, opening the program as normal and then reenabling the setting. After a programs runs for the first time, that setting no longer affects execution of it.

  • The least restrictive is "App Store and verified Developers". Before Sierra, there was a third option which was basically "Install what you want". This is not there any more...
