macbook pro using all bandwidth

I have a MacBook Pro for use at my work.


Our internet connection is not the best but recently i have been told that my PC is using all the bandwidth, even when i have very few programs running.


The company telephone is run on the internet and when I'm logged on the network it affects the connection.

The phone company are saying that i am using all the bandwidth.


Can someone advise how i can check to see what may be causing it.


Thanks in advance.

Any client on a network, including wireless clients you don't know about, could be consuming bandwidth. Wi-Fi networks must be protected with WPA2 security. If yours isn't, change the security setting on the access point. If it's already set that way, change the password. Make it a string of at least 8 random characters, including digits and upper- and lower-case letters. The password is saved in the keychain and you don't have to be able remember it; in fact, you shouldn't be able to remember it.

You make these changes in AirPort Utility, if the access point is an Apple device, or in a web browser otherwise.

If the network or the password was insecure, and bandwidth use returns to normal after securing it, you can be pretty sure the problem was caused by intruders.

But intrusion may not be the issue. Most often BitTorrent, iCloud, Dropbox, or some other cloud-data application is involved in cases of mysterious bandwidth use by a Mac. If you use iCloud, uncheck at least iCloud Drive in its preference pane and see whether there's any change. If you use third-party network backup or file-sync software, disable that. If you use a torrent client, remove it.

Otherwise, if you're running OS X 10.9 or later, you can see which processes are most active on the network.

Launch the Activity Monitor application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

Select All Processes from the View menu, if not already selected, and also select the Network tab.

Click the heading of the Sent Bytes column in the process table to sort the entries by bandwidth usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Repeat with the Rcvd Bytes column.

The only items questionable are:

- o1dbrowserplugin: Version: 5.41.0.0 - SDK 10.8 [Click for support]

I do not know what that is

- iPhotoPhotocast: Version: 7.0

That is a sharing app and may be sharing things over the internet

- SharePointBrowserPlugin: Version: 14.4.8 - SDK 10.6 [Click for support]

- googletalkbrowserplugin: Version: 5.41.0.0 - SDK 10.8 [Click for support]

Maybe the above two itemsare doing something

- SharePointBrowserPlugin: Version: 14.4.8 - SDK 10.6 [Click for support]

Maybe the above but I doubt it.


What does this show:

Also, open Activity Monitor which is in Finder>Applications>Utilities and click on Network and see what is using the network.

It could be apps like DropBox or iCloud Drive or iCloud Photos if you turned them one. It can take a while to sync to cloud
