Omnis Version for Mac OS X Mavericks (app nap)

[Michael Monschau]

Hi all:

There may be a way to do this programatically from c++ via the NSProcessInfo class. This class has a method called beginActivityWithOptions and endActivity which act on the current application process (I believe) and the options include things like NSActivityIdleDisplaySleepDisabled, NSActivityIdleSystemSleepDisabled and NSActivityAutomaticTerminationDisabled. These could be options that may prevent the App Nap but I am not certain. Unless someone else has already looked at these and found they do not work, I can raise a technical query with Apple as I have support with them and see if these indeed would do the trick. If they do, theoretically it should be possible to create external functions that could be called from Omnis 4GL, but it may take some playing around. I suspect it would require one to build with the 10.9 Mac OS SDK. I am not entirely set up for that but I could be as I have a 10.9 system on a spare disk, unless someone else wants to have a go.

Regards,
Michael

In such as case, you either completely disable app nap --- or disable it once, restart studio and then you are good till the next restart of your machine.
