Mac not sleeping normally?

If your mac doesn’t stay asleep, it’s easy to find what is waking it up.
From a terminal command, enter:

pmset -g assertions

In the first section of output, you’ll see the status of two kernel assertions (essentially, assumptions the system makes about the state of your system) named PreventSystemSleep and PreventUserIdleSystemSleep. An accompanying status of 1 for either of these means that it is currently triggered. For example, here’s what I see when I run that command on my iMac:

Assertion status system-wide:
PreventUserIdleDisplaySleep 0
PreventSystemSleep 0
PreventUserIdleSystemSleep 1
ExternalMedia 1
DisableLowPowerBatteryWarnings 0
UserIsActive 0
ApplePushServiceTask 0
BackgroundTask 0

Below this, I see:

Listed by owning process:
pid 9165(iTunes): [0x0000000100001192] 00:18:23 PreventUserIdleSystemSleep named: "Nameless (via IOPMAssertionCreate)"
pid 175(coreaudiod): [0x0000000100001287] 00:12:39 NoIdleSleepAssertion named: "'AppleHDAEngineOutput:1B,0,1,2:0'.noidlesleep"

This second section lists the processes which own any enabled assertions, by process ID (the number after pid) and bundle ID (the text in parentheses after that). For example, above, two processes are preventing sleep: iTunes (because I’m currently listening to music) and coreoudiod (probably because it’s processing iTunes’ music).

If the bundle ID doesn’t ring a bell, you can enter ps upat the Terminal command line, or look in Activity Monitor, to find the name of the command associated with that process. If you identify an app (such as iTunes in the example above), you can terminate it and put your Mac to sleep. If the process is something other than an app that you meant to run, terminating it may make your system unstable, which could cause it to crash—which would be a bit like sleeping, but not as nice.

Synology Cloud Station setup

If you are setting up Cloud Station for the first time here is a good checklist to make sure its setup right.

Please follow these instructions for setting up Cloud Station.

1. Install Cloud Station package via Package Center
2. Install Cloud Station Client onto computer. This is downloadable from our Download Center on our website located here.
3. Enable Home Service by going to Control Panel -> User -> Select User Home and enable it. This will create a “Homes” and “Home” shared folder. Homes has everyone’s Home folder in it. Home is the user you are logged in as personal share. Within that will be a folder for Cloud Station where your stuff will go.
4. Go to Main Menu -> Cloud Station and make sure that its enabled.
5. Now go back to Main Menu -> Cloud Station and make sure your accounts are enabled for this.
6. Then go to Control Panel -> ezCloud -> QuickConnect tab which is where you can customize your Cloud Station ID or use your login or the IP address.
7. Open up Cloud Station Client on the computer and use either the ID, login, or username and follow the wizard for setup.
