If you use GMail IMAP with Apple Mail, you might have experienced the dreaded garbled emails. This problem occurs when you move email messages to different folders. How do you know you have this problem? When you click on an email to view it, attached images and the mail headers are garbled; eg, you see all kinds of strange characters and the attached images are not viewable. This is a bug; not sure if it’s Apple Mail or Gmail, or both. You can read more the Gmail / Apple Mail garbled message issues here. The fix is simple: restart Apple Mail. But that is pretty clumsy. A better workaround is this: In Apple Mail, go to Mailbox > Rebuild. This is a workaround, not a fix. Let’s hope Apple and Google can put aside their feud in order to help their users :)
The Facebook Exporter for iPhoto makes is VERY easy to create image galleries on Facebook. I’ve never had much luck with the built-in photo gallery tool on Facebook; it works about 50% of the time and is buggy the rest of the time. Yesterday I discovered there is a Facebook Exporter app for iPhoto. Once you install it in iPhoto, lauch iPhoto, and select Export > Facebook (tab). You can create a new gallery or add photos to an existing gallery.
If you’re looking for a free Christmas gift, Google Chrome for the Mac was released yesterday, more than a year behind the Windows version. Better late than never. If you’re a Mac user, you’re probably aready used to getting late releases, or no release, for major software built for Windows. That’s one of the prices you pay to “think different.”

I just read about an easy way to create custom icons for folders in the Mac Leopard finder. Creating a custom folder icon makes it much easier to quickly find the folder in a list of folders that all look the same.
