Lotus Notes Standard Launch Issue on Mac OS

Technote (troubleshooting)


Lotus Notes Standard does not launch after installing JDK 7 on Mac OS X.

Diagnosing the problem

After installing JDK 7 on Mac OS X and unchecking JAVA 6 in Java Preferences, Lotus Notes Standard fails to launch.

When launching Lotus Notes Standard, the splash screen displays, after entering password, "Lotus Notes is starting, please wait..." briefly displays and then closes. Lotus Notes never loads.

Resolving the problem

This issue has been reported to Quality Engineering under SPR MCHZ8Y4RR3 and APAR LO71638. After investigation, it was confirmed Lotus Notes does not support JDK 7 as it is 64-bit only and Lotus Notes is 32-bit.


  • Leave Java SE 6 under Java Preferences (On the Mac, click on Apple icon > System Preferences > Java icon) checked ON (Java SE 7 can stay on top of the preferred order list).
  • Use Notes Basic (UseBasicNotes=1 in Notes Preferences file).
