How to Allow Opening Apps from Anywhere in MacOS Sequoia, Sonoma
Have you ever downloaded an app to your Mac and been unable to open it? Typically if this happens you’ll get some kind of alarming message, stating something to the effect of “App Not Opened. Apple could not verify (app name.app) is free of malware that may harm your Mac or compromise your privacy” with two options; Done, or Move to Trash. But what if you trust the app and its developer, and you actually want to open that app anyway? Because of how strict Gatekeeper is in modern MacOS versions, including MacOS Sequoia and macOS Sonoma, you will need to take some additional steps to allow the Mac to open apps downloaded from anywhere.
Because this tweak requires modifying Gatekeeper permissions to be less secure, and using the terminal to do so, this is really only appropriate for advanced Mac users who wish to allow the “Anywhere” option for opening unverified third party apps that have been downloaded from anywhere, including apps that have not been verified by Apple, or produced by developers who did not go through the typical Apple verification process. If you’re a casual Mac user, you likely won’t want to make this change to your MacOS.
