Sorry, no! (I work from home using a corporate laptop running WinXP.)
Have you read the other posts about getting DE running on a Mac, though? I think there was something about a one-off authorisation process needing to be done on Windows, then it could all be done on the Mac? If that's not familiar, then there's more info out there you need to have a look at...
[Later...]
What you need to do is get access to a Windows machine that you can install the Sony Desktop software and ADE and authorize it to your AdobeID.
Next, plug in your Sony Reader and then in ADE, select the Reader and choose "Authorize Device" from the Library menu (or similar - from memory so the wording may be off).
At this point you have a Sony Reader which is authorized to your AdobeID. For any eBooks you purchase on the Mac (with ADE 1.5 authorized to the same AdobeID), you will be able to copy the .pdf/.epub files to your Sony Reader, using the Finder, and then be able to view then on your Sony Reader.
