Find out what's keeping your Mac awake
I just get:
/Users/mikeytime: pmset -g assertions 03/07/2012 18:03:39 GMT+01:00 Assertion status system-wide: ChargeInhibit 0 NoDisplaySleepAssertion 0 CPUBoundAssertion 0 EnableIdleSleep 1 NoIdleSleepAssertion 0 DisableInflow 0 DisableLowPowerBatteryWarnings 0 ExternalMedia 0 No Assertions.

In 10.6 that is.

That's all that I get as well.

Very interesting — It's an entirely different list of assertions compared to the one I get!
So it appears that the available assertions may depend on the model of Mac you have…? The only two Macs I have access to right at this moment are a MacBookPro4,1 and a MacBookPro6,2… and they both give me identical lists of assertions, including the two I mention in the hint above. In short, I have no clue. But it would be interesting to investigate this further.

MacBookPro8,1 with 10.6.8 here.
On a Macmini4,1 running 10.6.8 server: thebank:~ administrator$ pmset -g assertions 05/07/2012 11:35:04 GMT+01:00 Assertion status system-wide: ChargeInhibit 0 NoDisplaySleepAssertion 0 CPUBoundAssertion 0 EnableIdleSleep 1 NoIdleSleepAssertion 1 DisableInflow 0 DisableLowPowerBatteryWarnings 0 ExternalMedia 0 Listed by owning process: 16446: NoIdleSleepAssertion value=255 named: "Time Machine backup"

Ah! I generally don't have my time-machine drive connected. When I plug it in to the USB port, I get this list:
gpc$ pmset -g assertions 7/5/12 11:43:48 AM EDT Assertion status system-wide: ChargeInhibit 0 NoDisplaySleepAssertion 0 CPUBoundAssertion 0 EnableIdleSleep 1 NoIdleSleepAssertion 0 DisableInflow 0 DisableLowPowerBatteryWarnings 0 ExternalMedia 1 Listed by owning process: 15: ExternalMedia value=255 named: "com.apple.powermanagement.externalmediamounted"So, the same list of assertions, and now one of them is owned by a process (instead of "No Assertions."). When a backup is running: gpc$ pmset -g assertions 7/5/12 12:02:43 PM EDT Assertion status system-wide: ChargeInhibit 0 NoDisplaySleepAssertion 0 CPUBoundAssertion 0 EnableIdleSleep 1 NoIdleSleepAssertion 1 DisableInflow 0 DisableLowPowerBatteryWarnings 0 ExternalMedia 1 Listed by owning process: 15: ExternalMedia value=255 named: "com.apple.powermanagement.externalmediamounted" 692: NoIdleSleepAssertion value=255 named: "Time Machine backup"So perhaps on this MBP6,2 in 10.6.8 it is NoIdleSleepAssertion that plays the role of the ones mentioned in the hint. It may be the SMC Version or the Boot ROM that's relevant, rather than the model.

I have no idea if the model makes a difference. I just included it because it seemed like another variable that could be relevant. |
