Based on OIT testing, the page provides a useful guide for which software is recommended, near end of life, should be upgraded or is in an early-adoption phase. OIT’s Software Life Cycle page provides guidance to the campus community on recommended operating systems, productivity applications, web browsers, and email & calendar software. All others are welcome to contact the IT Service Center ( or 30) or schedule an appointment with OIT’s Buff Techs desktop support team for help to upgrade. If you are a customer of OIT’s Dedicated Desktop Support service and would like help or have questions about upgrading your operating system, please submit a request through the Dedicated Desktop Support Service Request Portal. Software vendors have quickly followed suit and no longer support products on High Sierra which includes Microsoft Office 365 and Adobe CC 2021. Apple fixed the vulnerability in Big Sur 11.2.1, Catalina 10.15.7 and Mojave 10.14.6, but did not fix High Sierra and dropped support for that version. In early February, a severe security flaw was discovered in macOS. Not only that, but the campus recommended antivirus for Macs is no longer supported on High Sierra which means Macs that are running this older operating system are no longer protected from viruses and other malicious attacks. Here is a flowchart that might help guide you in choosing a source for Java 11.If you’re running macOS High Sierra 10.13 or earlier versions of macOS, you should upgrade to a newer version of macOS immediately as High Sierra and older versions are no longer supported by Apple. This approach using rapid delivery train with LTS is new in the Java world. Free-of-cost implementations may also receive updates under LTS from some providers. This applies, at least, customers paying a commercial vendor. This means the version will receive updates and fixes for years instead of months. Versions 8 and 11 are both LTS, as will be version 17. The exception is that every three years, the sixth release in succession shall be designated a Long-Term Support (LTS) version. However, these versions may not be supported free-of-cost with patches after the successive version arrives. These are production-ready fully-tested releases. Every six months a new version arrives, as discussed in this article.

Oracle and the Java community have adopted a faster cadences for releases, a fashion known as the Release Train. A software upgrade is usually a generational step up to a newer macOS upgrade from 10.13 High Sierra to 10.14 Mojave, for example, or from 10. Note that Java development has changed recently. Java 12, not yet released for production, runs on High Sierra as well. The implementations of Java 8, 9, 10, and 11 based on OpenJDK from vendors such as Azul Systems, Oracle, and AdoptOpenJDK run on macOS High Sierra and Mojave (and some older macOS as well).
