To start, you can transfer your existing BBEdit preference settings from one Mac to another as follows:
Please make sure BBEdit is not running on either machine, then open the Terminal app on the _source Mac_ and enter the following command (you can copy & paste it):
defaults export com.barebones.bbedit ~/Desktop/BBEditPreferences.plist
Next, transfer the resulting file ("BBEditPreferences.plist") to the Desktop on your _target Mac_, which you can do by any standard means (e.g. via iCloud Drive, AirDrop, or an USB thumb drive).
Then, launch the Terminal app on the target Mac and run the following command to apply the transferred prefs (again, you can copy & paste it):
defaults import com.barebones.bbedit ~/Desktop/BBEditPreferences.plist
In addition, if you have any existing app support items, such as clippings, scripts, and/or text factories, you can also transfer those items from your original machine to the new one.
For complete details on the location and purposes of these items, please see Chapter 2 of the included PDF manual (available at any time by choosing Help -> User Manual).
