7 +The Jetbrains JDK releases are unofficial but they provide JREs patched with the DCEVM. They are available at [[https:~~/~~/github.com/JetBrains/JetBrainsRuntime/releases>>url:https://github.com/JetBrains/JetBrainsRuntime/releases||shape="rect"]] . These instructions were tested with Release 17_0_1-b164.4, architecture osx-x64, JBR with JCEF (DCEVM) , [[jbr>>url:https://cache-redirector.jetbrains.com/intellij-jbr/jbr_dcevm-17_0_1-osx-x64-b164.4.tar.gz||shape="rect"]]  and [[jbrsdk>>url:https://cache-redirector.jetbrains.com/intellij-jbr/jbrsdk_dcevm-17_0_1-osx-x64-b164.4.tar.gz||shape="rect"]]. They should also work with architecture osx-aarch64.
