Kindle for Mac, Amazon's Mac application that allows you to read Kindle e-books on your computer, has been updated and given a fresh coat of paint.
Amazon's updated reader now lets you add and edit notes and highlight passages, both of which are synced across all Kindle devices and apps using the company's Whispersync technology. This update also includes the ability to search within a book, a much-requested feature. Multi-column reading mode, which was just added to the iOS Kindle apps, makes its debut on Kindle for Mac with this release as well.
New features aren't the only changes in this release. The app sports a refreshed user interface that is much cleaner and, to this blogger's eye, looks more 'Mac like' (I can't define it, but I know it when I see it).
As always, Kindle for Mac allows you use your Mac to read any e-book that you purchased from Amazon's Kindle Store. It also syncs your current reading location as well as notes and highlights across all members of the Kindle ecosystem, including hardware Kindles and the variety of Kindle applications for both computers and smartphones.
Kindle for Mac is free and requires OS X 10.5 or higher.
