Common Problems and Solutions

Rebound! doesn't restart my computer after the system crashes.

Some crashes which appear to be system crashes are actually caused by applications. Though the system may appear unresponsive, other processes are still running normally. See How Rebound! works for more information.

I disabled my Rebound! software, but my computer keeps restarting every few minutes.

If the "Number of restart attempts" slider in the "Application Crashes" panel is set higher than '1', the Rebound! hardware will wait for the Rebound! software to reestablish communication at startup. Since the software has been disabled, this won't occur, and the Rebound! hardware will restart the computer again.

To avoid this problem, always set this slider to '1' before disabling the software.

Rebound! doesn't recover after an application crashes.

It is possible for applications to fail in ways that do not cause actual crashes. Our "application timer" technology gives Rebound! another method of detecting application failures. An application must be specifically written to support Rebound!'s application timers. Contact your application's developer to see if they offer Rebound! support.

Tip: Rebound! uses the same software as our Rebound! product, so if your application supports Rebound!'s application timers, it automatically supports Rebound! as well.

If you are running an application which includes support for Rebound!'s application timers, make sure its timer is being set. Open the Rebound! control panel and click on the "Application Crashes" tab. The timer should be shown in the list at the bottom of the panel. If it does not appear, check your application's user manual to configure this support.

Rebound! restarts my computer when I run some applications or tasks.

Some long operations will take control of the computer, and not give time to any other processes, including the Rebound! Extension. The Rebound! unit interprets this as a crash. Increase the value of the "Restart if system doesn't respond" slider in the "System Crashes" panel.

Some applications, including some disk utilities and games, will take control of the computer for very long times. If you need to run one of these programs, you should temporarily uncheck the "Monitor system for crashes" box in the "System Crashes" panel.

Tip: This can be done automatically with AppleScript. See "Using Rebound! with AppleScript" in the Rebound! user manual for more information.

An error message appears at startup every time Rebound! restarts my computer, saying the computer was shut down improperly.

This is a standard message that appears in Mac OS after a crash occurs. You can disable this message in the General Controls control panel. Uncheck the box labelled "Warn me if computer was shut down improperly."

My log shows that Rebound! restarted due to a system crash immediately after startup.

Rebound! can't add an entry to your log while the computer is crashed, so it adds one after it restarts the computer. The monoLog software must be running before Rebound! can add its entry, so the "monoLog Extension started" entry will appear before the crash (or any other) entry.
