Turning off the Sudden Motion Sensor on your Mac
Has your Mac ever quit unexpectedly during a set? It may have happened because of the Sudden Motion Sensor getting activated and shutting down your computer.
My friend Paul (who works at Apple) sent me this link: Apple Portables: Advanced tips for Sudden Motion Sensor and described a problem he had encountered while running Logic Pro during a recent gig:
"Thought you might want to consider this information. I have had a few issues recently where my MacBook Pro has stalled during a worship service (while we are playing). If using Logic (with Midi) this can cause the playback to stop (and give an error message). (I think that the vibrations from the bass guitar or the kit (when heavy hitting) have caused the sudden motion sensor to trip.)."
And then:
"I was able to re-create the issue last night by deliberately triggering the sudden motion sensor (you can do this by rotating the computer...and then you will hear a "click sound"). When this sensor activates the HD shuts down for a split second. This can cause issues sometimes during playback."
Personally, I've never experienced this problem, though my computer did freeze one time before a set began. I had to get the MC to stall for a bit while I rebooted my computer.
I'm not sure I want to turn off the Sudden Motion Sensor in my Mac as, I think the sensor helps protect the computer from damage, should I drop it or it fall off as stage as Nathan's computer did during a recent show I played with him. His laptop fell about 7 feet, flipping over in the process, losing a cable and landing upright. Nothing broke, and he was able to continue using his computer almost immediately. I'm thinking the Sudden Motion sensor saved his hard drive...but still...it'd be nice not to have to worry that my computer might shut down in the middle of the set.
Do you have any suggestions for keeping your Laptop safe during a peformance? Any special stands or trays that you use? If so, leave a comment...I'd love to hear your solutions for keeping your computer stable during a show.
