Configuring Mac OS X Server to Start Up in 32-Bit Mode

You can configure Mac OS X Server to start up in 32-bit mode by default. This affects
Mac OS X Server installed on this volume, but not installations of Mac OS X or
Mac OS X Server on other volumes.

Afterwards, you can later reconfigure Mac OS X Server to start up in 64-bit mode by
default.

To configure Mac OS X Server to start up in 32-bit mode:

1

Open Server Diagnostics Mac OS X.

You should see a dialog asking you if you want to permanently configure Mac OS X
Server to run in 32-bit mode. If it doesn’t appear, Mac OS X Server is already running in
32-bit mode.

2

In the dialog that appears, click “Configure and Restart.”

The server restarts in 32-bit mode and loads the volume with Server Diagnostics
Mac OS X installed.

To reconfigure Mac OS X Server to start up in 64-bit mode:

1

On the Mac OS X Server volume that you want to start up in 64-bit mode, open

Terminal (in /Utilities/).
