Use nettop command to check per-application network activity in OS X

While broadband Internet speeds let you do more online, if your system uses a lot of bandwidth, you might run into some limitations. In some cases, ISPs may throttle your network speed after you have reached a certain usage level, or may even charge you additional fees for the extra bandwidth used. In other cases, a constant upload or download from one system may saturate your bandwidth and greatly slow down Internet-based activities for the other computers that share the connection.

For the most part, programs will not use a great amount of bandwidth, but there are times when one … Read more

How to add line breaks between list items in OS X Mail

When composing messages in OS X Mail, you have the option to use the program's built-in list tool to keep numbered or bulleted lists properly formatted, but you may find its formatting options to be a bit limited.

The list generator is not intended to be a complex option; however, by default it only displays one list entry per paragraph, so if you attempt to create a line break to separate list items or add multiple paragraphs per item, the default behavior is to simply append new list entries.

This can be a bit annoying to deal with, and … Read more

Addressing mailbox access errors in OS X Mail

Apple's Mail program in OS X for the most part offers a quick and basic approach to e-mail, but occasionally you may run into problems such as not being able to access messages, whether you get error messages or simply can't locate them.

Similarly to OS X's Spotlight search feature, Mail uses an index to show the available e-mail messages that have been downloaded to the program, listing information such as subject, sender, and whether messages have been read and linking this information with the respective message file.

Errors involving the index can result in a number … Read more

While the latest version of Java Apple developed (Java SE 6) is supported in Snow Leopard, support for this version of OS X ended when Apple passed the baton to Oracle to maintain Java.

With Java SE 7 requiring OS X 10.7 or later, … Read more
