Why is one Mac using up so much bandwidth ???

[mikkydoos]

Hi all,

 

I've fairly recently put in a Mac which is a secondary Papercut server for Ipads.

 

I've just run a report from my firewall (smoothwall) to investigate bandwidth consumption.

 

The second biggest bandwith usage is reported as coming from the Mac @ 12gb last week.

 

 

Any ideas what its doing. Its pretty vanilla and as it came out of the box.

 

 

(I am no Mac expert!)

If it came out the box is it downloading OS updates?

[mikkydoos]

No its about 4 months old.

 

OK anyone know how to turn off all the notifications etc that are looking for data on the 'net ?

Does your report not say where the traffic is going? If you can get an idea of that, you should be more able to easily identify what's eating the bandwidth and kill it.

Yeah, im looking at it now. Cheers

Could still be updates. There have been a number of fairly big ones in the last couple of weeks (although not 12GB big), and OS X has a habit of just downloading them whenever it feels like.

 

You can turn off notification here: https://support.apple.com/kb/PH18740?locale=en_US or for an unoffical, kill all switch - Permanently Disable Notification Center in OS X Mountain Lion (should work with Yosemite too).

I've disabled it all now. Doesn't half run quicker !
