“adb” can’t be opened because Apple cannot check it for malicious software

Question

I faced the following problem: when I try to make a RN project as in tutorial, I have the next window: “adb” can’t be opened because Apple cannot check it for malicious software.

Yes, I know that when I have such window I should open the app in finder, click the right button of the mouse and then click "open".
But in this situation I cannot do it, as there's no way to open adb in finder, so, how can I solve this problem?

Answer 1

The other answer didn't work for me.

I searched for adb like this

which adb

Then terminal told me the path to the adb executable, so I opened that location

open /usr/local/bin

Then right-clicked on it, and chose open, and then I did have the option to open the app instead of just move to trash.

Answer 2

Open "System Preferences" -> "Security & Privacy" -> "General".

Under "Allow apps downloaded from:" click "Allow Anyway" on adb, then try again.
