If you frequently use a Mac computer and need to connect to Windows machines via Terminal Services then be sure to download the Microsoft Remote Desktop Connection Client for Mac 2.0. The link above gives a full description of all the features of the 2.0 client, but the most notable is support for the new RDP 6.0 specification.

If you use a Mac as your primary home machine and work with Windows computers at work, then this program is a must have.
