Oct 20, 2019 Though the best way is to install apps from Mac App Store it has few problems. First, many people confuse iOS App Store with Mac App Store – they are two different stores. Second, there are only few apps available in Mac App Store that will not cater your requirements. This makes you to look for apps from third-party websites. Apr 07, 2017 To open an unsigned app, you need to right-click or Control-click the app and select “Open”. This works on macOS Sierra as well as previous versions of macOS. You’ll be warned that the app is from an unidentified developer–in other words, it isn’t signed with a valid developer signature. If you trust the app, click “Open” to run it.
When you download an application like a screensaver from the internet and try to open it on OS X, you may get a warning that the file 'can't be opened because it is from an unidentified developer'. Xbox app fro mac.
This is due to a default security setting which will only allow the installation of apps from the App Store or identified developers. You can only click 'OK' to close the window with the warning message, and the app will not be started.
WorkaroundsRight-click or Control-click to open
When you click the file you want to open using your right mouse button (instead of double-clicking with the left button), you will see a context menu with several options. One of those is 'Open'. Clicking that tells the operating system you explicitly want to open this file.
Google chrome settings continue running background apps. Instead of using your right mouse button, you can also click the file with your left mouse button while holding the Control (ctrl) key to access the same context menu.
You will still get the warning message, but this time you have an extra option to click an 'Open' button, which will actually launch the application — bypassing the security setting.
Change security preference
If you want to stop receiving these warning messages, you can change your settings to allow opening apps downloaded from anywhere, not just the App Store or identified developers.
Note that this setting will be reset back to 'Mac App Store and identified developers' if you have not opened any apps from unidentified developers in a 30 day period.

New mac apps 2015. I've had LibreOffice for years. Now with the release of 4.3.2.2, I can't open the app because 'the identity of the developer cannot be confirmed.' Get the same error message for 4.2.6. I run a Mac Book Pro, 13', mid-2009, 8 GB, 2.26 GHz 1067 MHz DDR3. The OS is 10.9.5.
