Hi John,

If it's not too much work, I would implement it in Rcmdr because I
don't know if there are other consequences of App Nap, so until the
dust settles using the defaults system might be ok.

Hi Rob,

You've just answered my next question! I was holding off to give you

a

chance to address the issue directly in R.app.

Is there any reason for me, at least for the time-being, not to do

this from

the Rcmdr via system()? I just tried, and that seems to work. If

necessary,

I could check for the existence and (if it exists) the current state

of this

key, and restore that when the Commander() exits. Of course, if you

plan to

address the issue directly soon, it doesn't make sense for me to do

so.

Thanks again for your help.

John

Hi John,

If you want to play around with NSAppSleepDisabled yourself, you

can,

in a Terminal:

defaults write org.R-project.R NSAppSleepDisabled -bool yes

to check the setting:

defaults read org.R-project.R NSAppSleepDisabled

or to re-enable AppNap:

defaults write org.R-project.R NSAppSleepDisabled -bool no

or just delete the key:

defaults delete org.R-project.R NSAppSleepDisabled

	Hi John,

	I'm just starting, but it look likes 'defaults write ...' can be
used to manage the setting. Not elegant, but maybe temporarily ok

for

tcltk users.

	Someone from TexShop (Richard Koch) reported that if R.app is
compiled against the 10.9 APIs, the 'Prevent App Nap' check box will
not appear. The ultimate solution is for R.app to know when App Nap
should not kick in, there is a new API for that.

	So, some more homework...

		Hi Rob,

		Thanks for the explanation -- that makes sense of the

current

behaviour. I think that you know that I'm not very knowledgeable

about

OS X. A couple of follow-up questions:

		If you make this change to R.app, will the default be to
disable App Nap or just to provide the check box?

		If App Nap isn't disable by R.app by default, would it be
possible to disable it under program control, e.g., when the Rcmdr
package is loaded?

		Best,
		John

			Hi John,

			Looking at Activity Monitor on my system, R will

always

take up say 2.5% CPU time while R.app will almost go away if it is

not

active. This might be because in a terminal the process might not be
treated as a pure application but maybe more as a traditional Unix
process. But that's just a guess from my side.

			What surprised me a bit is that we couldn't switch

off

App Nap, as is possible with several other apps (go to the Info

panel

of an app and it should show a 'Prevent App Nap' box, e.g. Dropbox).
R.app did not show that box, probably a consequence of an older
build/project creation?

			Anyway, on my system I added that property in the
info.plist and disabled the App Nap behavior. It seems to be working
fine now. I'll do some more testing to see if I can get the check

box

on the Info screen show up and check with Simon if it's ok to commit
the change. Of course, in that case R.app will also always consume

2.5%

CPU. Under the energy tab of the Activity Monitor you can see which
apps allow App Nap.

				Dear Rob et al.,

				I'm glad that there's progress in

understanding

the source of the problem, but I wonder why the problem doesn't
manifest itself -- at least in my experience -- when R runs in a
terminal window.

						For me, library(tcltk);

demo(tkfaq),

click to focus, then use Fn-Down (i.e. PgDown) to go to the bottom

of

the file, Fn-Up to the top, etc. Less than two iteration for me

before

the effect kicks in.

wonder if anyone

has seen this behavior after rebuilding R.app on Mavericks (from the
R.app sources).
