Title: xD does NOT work on MacBook Pro
Review: Works fine with SD cards but Siig support confirmed an issue I was having regarding xD media not mounting on Mac OS X...We did not market this reader/writer for Mac because of compatibilityissues with xD cards in the Mac, there is no fix for this issue.However, we will update to a different version soon that will be fullycompatible in Mac OS 10.4.7 or later.
