All Mac users are undoubtedly familiar with Mac OS X Mail's standard Dock icon. The hawk-in-flight against the blue background of a postage stamp is a no doubt familiar sight. The hawk-in-flight against the blue background of a postage stamp is a no doubt familiar sight. I love icons and customizing my Mac desktop, so I decided to share with you all my personal bookmark list of free mac icons. These are the sites I visit when I want to change my Mac appearance and all the icons that define the OS X desktop and dock. As long as your Mac is connected to the Internet, it will create the correct settings so that you can use Gmail’s mail, calendars, reminders, messages, and notes features. The Mail/Email icon should stay in the dock for you now. If this is the answer to your question, please kindly select * ACCEPT * so I can be rewarded for my efforts.
