How to Sync Thunderbird Mails across Mac and PC

One of the beauties of Thunderbird is its mail data are both Mac and PC compatible.  One can simply copy the mail data from one platform to the other and then open it without any problem.

Like many others, my desktop is a Win-7 based PC and my portable is a Mac.  Since I have a free Dropbox account, I just configure Thunderbird to put the mail data under the Dropbox folder on both machines.  Mails received on either platform will then be automatically synced to the other.

Account Setting: Define Mail Data Folder under Dropbox

NOTE:

  • Thunderbird MUST NOT be run simultaneously on both machines; otherwise, mail data will be messed up.
  • The sync process may take from a few seconds to a few minutes depending on the size of the data and the speed of the network.
  • Therefore, it is better to wait a few moments before opening up Thunderbird on the other platform until Dropbox’s Files Sync action is completed.

How to Uninstall Apps Cleanly

When switching from PC to Mac, I once wondered how apps could be uninstalled since most apps don’t have an uninstaller, and you wouldn’t be able to find anything called “Programs and Features” in the System Preferences (equivalent to Control Panel on PC).

Actually, to uninstall an app on Mac is quite simple — just Move it to the Trash will do.

But to ensure no “tails” are left behind after the uninstallation, one can install a free App called AppCleaner.  It not only helps uninstall an app but also can effectively remove “tails” associated with the app being trashed.

How to Change Machine Name

To change the name of the Mac, open Sharing in System Preferences.

Enter or change the name of your choice at the space provide:

Note:
Don’t mix this Machine Name up with Short Name and Full Name.   Machine Name is the name you want to call your Mac and to be shown to others in a network environment.

Short Name and Full Name are the names of the user of the Mac.  These two are used to identify who is the user, and to define and create account information on the Mac.
