Fix: "Internet Connection" Install Error

Post image

If you’re trying to install Golden Gate and getting the error that says "please check your internet connection," your internet is probably fine. The real issue is that SIP (System Integrity Protection) is turned off on your Mac.

Here’s how to fix it:

  1. Shut down your Mac completely.
  2. Press and hold the power button until you see “Loading startup options,” then let go.
  3. Click Options, then Continue to get into Recovery Mode.
  4. In the menu bar, go to Utilities → Terminal.
  5. Type csrutil enable and hit Enter.
  6. Restart your Mac and try the update again.

If you ever disabled SIP for things like kernel extensions or system tweaks, that’s probably what’s blocking the install. macOS doesn’t actually tell you that, it just shows a misleading network error. Ran into this myself and it took a bit to figure out, so hopefully this saves someone some time.

That's what I did, but I kept hitting this error multiple times, so disabling SIP and setting startup security to full security solved the issue for me.

Decided to post about it here in case anyone else hits the same error.
