Can’t be opened because it is from an unidentified developer

Open toddcf opened this issue 6 years ago • 9 comments

I am using MacOS High Sierra, version 10.13.14.

I have downloaded git_osx_installer, but when I try to open it to install it, I get this warning message:

"Can’t be opened because it is from an unidentified developer."

I clicked the question mark and followed the Mac Help instructions to control-click and choose Open (which is supposed to save the app as an exception in my security settings), but nothing happens.

You can bypass this issue just installing Xcode Command Line Tools (without the complete huge Xcode) just by running xcode-select --install.

Maybe you'll get an older git version, (2.15.1 right now), but you can expect it to be upgraded along with macOS upgrades.

And you won't have the GUI tools. To me, this is the best choice if you need Git command line on Mac in a lighweight way.

Type sudo spctl --master-disable at the command line and install programs as usual

Just for my own edification, why is git still from an unidentified developer? What does that even mean, technically?

I had already install the Xcode Command Line Tools but i still get the same message

Sure @Sweinzierl28 : installing Xcode Command Line Tools doesn't help installing a downloaded package from outside the App Store. It just brings you the Git command line tools, which was my goal when trying to install the downloaded package.

So now you should have Git installed. Try running git --version in a terminal.

@5forcegees as far as i understand, this means that this package hosted in GitHub does not contain a signature of a developer recognised by Apple. All packages in the App Store do, and some other packages available in the web may also contain it. So, from the point of view of Apple, this package could be created from any untrusted developer, which is potentially harmful (differently that developers that Apple trust). Obviously, this does not mean that this package must be harmful.

I guess macOS would give you the chance to install an unsigned package. That's what a warning has different than an error: warnings let you continue the process. If, in your case, it is not actually installed, you should research further. Or contact the author, @timcharper , for support.
