So the user has two options: Downgrade or remove Java or settle for running Notes in Basic Mode. The second document is accurate Notes will not currently run in Standard Mode if you install Java 8 Update 152 or later on your Mac. The first document above turns out to be inaccurate Notes will in fact run in Basic Mode on the Mac. This IBM document states that 64-bit Notes will not run on MacOS if you upgrade Java to version 8 Update 152 (or later).This IBM document states that 64-bit Notes running on MacOS does not support Basic Mode.With IBM's help (I opened a PMR) I soon discovered two things: My client asked me to help figure out what the problem was and how to get Notes running again in Standard Mode. He figured out how to run Notes in Basic Mode (i.e., without the Eclipse wrapper that provides additional, Java-based functionality to the Notes client, which is known as 'Standard Mode') and concluded that his upgrade of Java must have caused the problem. The client is a software publisher and the user is a developer. Late last week a RockTeam client notified me that a user upgraded Java on his Macintosh to Java 9.0.1, then discovered that IBM Notes would no longer start on the machine.
