Hi Shadowman
I'm a Machead and I'm sure you can grow to love it as much as I do.
A few tips...
I have had some problems with the Stuffit expander on certain rar files, particularly if there is a complex password to open the file. Stuffit is great for autodownloading zips and stuff, but I also use this:
http://rarexpander.sourceforge.net/index.html
for when I encounter problems with particular files. Best to use the stutffit as the default expander and use the rarexpander for rare cases.
(Anothr tip: stuffit doesn't like it if rar files have really long names or have words divided by hyphens or underscores; an example: you download a file named 'jane-supermodel_photoset-blahblahblah-part001.rar'. Sometimes stuffit will refuse to open a file like this. But tis easily resolved. Simply insert a full stop and make the file name shorter. Using the same example: manually change the file names to 'jan.e-supermodel_photoset-blahblahblah-part001.rar'; and be sure to place a full stop in the same place in each rar file. Then try stuffit again. It will create a new folder just called 'jan' and then put the opened rar file inside it. Hope I've explained that so it makes sense!)
Also, search for a free download of flip4mac and install it. This allows you to watch WMV movies via Quicktime. Some WMV files don't play well on the Mac system. flip4mac is a very small file and it just attaches itself to your existing Quicktime programme so when you click on any wmv file it automatically opens it. Playback is faultless.
