P: Does not release Power Management Assertions on OS X 10.10 Yosemite.

[FeedbackCommunityMember]

On Save operation Photoshop creates an operation system power management assertion which prevents the operating system to go in idle system sleep mode during save operation. Good idea in theory! My Problem is that Photoshop does not remove these assertions when the save operation is finished. I have to quit Photoshop to remove these assertions.

I checked this on command line with the following command

macmini:~ alexander$ pmset -g assertions
2015-07-12 16:10:35 +0200
Assertion status system-wide:
BackgroundTask 0
ApplePushServiceTask 0
UserIsActive 0
PreventUserIdleDisplaySleep 0
PreventSystemSleep 0
ExternalMedia 1
PreventUserIdleSystemSleep 1
NetworkClientActive 0

pid 53(powerd): [0x000000070008012c] 162:17:59 ExternalMedia named: "com.apple.powermanagement.externalmediamounted"
Kernel Assertions: 0x4=USB

id=501 level=255 0x4=USB mod=12.07.15 12:20 description=EHC2 owner=AppleUSBEHCI

PreventUserIdleSystemSleep means no idle system sleep any more until the assertion is gone. This Problem is new in Photoshop CC 2015. CC 2014 does not have this problem.

After some more editingI can see even more assertions even without any open image in photoshop.

You don't want the system to go to sleep while the file is saving (because you could lose the file). The background save should prevent sleep, because it is saving a file.

[FeedbackCommunityMember]

That's true and these Assertions are good, but Photoshop should release these Assertions when the saving is finished. Right?

[FeedbackCommunityMember]

Here you see the problem. No open image in photoshop at all and still assertions that prevent power management. Some of them are older than 1 Day.

[FeedbackCommunityMember]

OK, we'll have to investigate and see if we can reproduce that problem.

I'm having this same exact problem. Any resolution yet?

I reported the same problem on July 6 on the community forum for Photoshop.

Me too. (Is there a better way to register interest in an issue?)

This is the correct place to report issues.

This should be fixed in our next update. Stay tuned.

Just updated. Not fixed. Both Photoshop and Dreamweaver prevent sleeping.

[Richard Lohr Studio]

I just upgraded all my CC apps, and now both Photoshop and Dreamweaver are preventing sleep. Yosemite 10.5.5

[FeedbackCommunityMember]

It appears the latest update did not fix this. Photoshop still is blocking sleep. I can provide more details if needed.

[Ed_M]

Consistent with what I originally reported back in July (see comment posted August 11 above), Photoshop CC 2015 continues to prevent auto-sleep on my Mac Pro running Yosemite 10.10.5

Photoshop hasn't had an update since late July. This will be fixed in the next Photoshop update.

[Richard Lohr Studio]

Photoshop had an update within the past two weeks, actually.

[FeedbackCommunityMember]

No, it has not. It sounds like you got the Camera Raw update (from a few weeks ago) confused with a Photoshop update (which hasn't happened since late July).

[Richard Lohr Studio]

I see. I guess I will just have to quit CC apps to avoid screen burn. Bummer.

[Ed_M]

The latest Photoshop CC update has fixed this problem on my Mac. Thanks.
