Should I install an app from an unknown developer/unidentified developer?
Apple has a lot of mastery over the apps available for Macs , iPads and iPhones . While the Mac is a short more assailable than iOS ( the only way to get third - party apps onto your iPhone and iPad is to download them from the iOS App Store ) there are still a good deal of basketball hoop to derail through before you could install and run some third - party apps on your Mac .
These step are designed to protect users from malware disguise as an app that we imagine we can trust . It might even look like a well - known app but have malicious computer code added to it . While we can all follow the advice not to download apps from file - sharing sites , or via links on dodgy - looking emails , Apple ’s put in measures to make it harder for us to install apps that might be severe .
These measures include Gatekeeper , which is Apple ’s name for the certificate aspect of macOS that checks apps for malware and quarantine them . It also checks whether the app is write by a developer known to Apple ( apps that have been checked are often referred to as “ signed ” apps ) . Then , even if it match those necessity , Gatekeeper will ask you to support that you want to enter the app .

Apple say that maintaining a horizontal surface of control over the apps we can put in on our equipment protects us from malware and a unsound user experience , but it can be frustrative and worrying if you require to run an app and you are confronted by a warning that it is from an unknown developer .
Should you see a warning that an app is from an unknown developer or an unknown developer this does n’t think that the app is probable to be malware . It just means that the developer has n’t signed up to Apple ’s developer program and jumped through Apple ’s hoops . You should work out carefulness though . Before you open such an app you should be quenched that the developer and software program ( and the way of distribution , since innocent apps can be hijacked by guilty parties ) are legit .
