I've posted before about CrossLoop as a potential IT solution and remote support tool for smaller firms in  Cover Your Assets: CrossLoop – Affordable IT Support for Small Practices. CrossLoop provides a free screen shraing utility that allows you share your desktop with a friend. Or you can use it to work on someone else's system. You can also connect with one of the computer support people who offer their services for a fee on CroossLoop ( CrossLoop refers to them as Helpers). However, at that time, CrossLoop was only available for the PC, not the Mac. That is no longer true with the release of CrossLoop for the Mac which you can download from the CrossLoop site here.

CrossLoop lists the Requirements as:

• OSX 10.4 (Tiger) or later
• an Intel processor
• 20MB disk space and 500MB of RAM.

One caveat though: PowerPC Mac users need not apply – it won't run on them. 

You can read more on the CrossLoop blog post CrossLoop Mac Gets a Lot of Love .. and Hugs which also inlcudes links to stories picked up by the NYT, Washington Post, LifeHacker, TechCrunch and other major outlets.

With CrossLoop available for both the PC and Mac, you now have an easy to us,e cross platform support program that's free, but which can also help you get professional assitance if you need it.
