Internet connection while macbook sleeps?

[sneak3]

Hello!

I have a macbook pro on mountain lion 10.8.5.

I was wondering what happens with my internet connection, for example, while downloading stuff with safari/chrome AND while patching game clients.

Does OSX know it needs to keep those services active even if I set auto sleep to something like 10 minutes?

How exactly does OSX handles that kind of thing?

The machine won't sleep unless it's inactive.

So if there is a constant data flow through internet, meaning background torrents, app updates or game patchers, it won sleep at all but will turn off screen?

If thats true, what is that app Caffeine for? Many people seems to use it.

Not all apps have been rewritten to use the newer APIs that Mountain Lion introduced, which is where Caffeine comes in.

Example : My mini kept going to sleep when Transmission (torrent client) was active, took them a couple of months to update the app if memory serves.

Hmm that does make sense.

So how could I tell if the app being used is updaded enough?

Should I just use caffeine and forget avou this?

First off, I recommend you update to Mavericks. Mavericks is much smarter about power management. So smart, that Apple has even removed the sleep timer setting in Energy Management Prefs.
