Java has not been pre-installed on Macs since OS X version 10.7 (Lion) and later. To download and install the latest version of Java from Oracle, Mac users who are running OS X version 10.7 or later need to visit the Java.com web site. Going through the Java update process helps to keep your Mac safe from potential Java vulnerabilities. Allow Java to update. If Java finds an available update, follow any on-screen prompts to confirm the update, then allow your computer to install the latest version of Java. If you receive a message that says you're already running the latest version of Java, you can't update Java. In this video I show you the only solution for the java installer: download failed error that happens while java is updating automatically. In successfully updating to OS X 10.4.11 from 10.4.10 the subject java update, 'Java for Mac OS X 10.4, Release 6', came up from Software Update. In trying to install it, it stalled at the very end of the installation. It again failed on a second try.

Diagnosis: Modern macOS, like Mojave and Big Sur, includes a technology called Gatekeeper, which is built to help you safely open apps on your Mac. For sure Apple App Store is the best place to get software applications, but in many cases, you'll need to download and install apps out of the store. To distribute apps without App Store, it requires the developer to have valid Apple Developer ID and get their apps notarized. Otherwise, it has large chance that they'll get the following error: 'XXX can't be opened because Apple cannot check it for malicious software.'
