Enterprise server action required after upgrading to OS X Mountain Lion

This article applies to CrashPlan PROe version 4.


Both CrashPlan PROe and SharePlan are fully compatible with Apple's OS X Mountain Lion version 10.8. However, you may need to install or reinstall Java after successfully upgrading to OS X Mountain Lion. This article describes the steps needed to ensure your enterprise server works properly after upgrading your system.


Mac systems upgraded to OS X Mountain Lion (OS X v10.8) running CrashPlan PROe version 3.8.2010 and later

Before you begin

This article assumes you have already upgraded your Mac to OS X Mountain Lion.

  1. Open CrashPlan PROe or SharePlan on the enterprise server
  2. When prompted, install Java.
    Software Update installs Java. If this installation fails, download Java 1.6 directly from Apple's support page.JavaSE6.png

After Software Update is finished installing Java, the administration console opens and CrashPlan PROe and SharePlan operate normally.

Alternative solution (CrashPlan PROe version 3.5.2 or later)

If you do not want to install Java 1.6, then it is possible to use Java 1.7 JDK by modifying the JVM file; however, this is an unsupported process that could have unintended consequences for other apps that also use Java.

This alternative solution requires CrashPlan PROe 3.5.2 or later.
