This post comes a bit late but… I’ve managed to publish the mac version of my PastefireClient app. This version comes in the form of a system service and a preference pane to insert your pastefire.com credentials.

It’s system service to send content (text, phone numbers, addresses, URLs) to the PasteFire App on your iPhone.

Once installed the service is present in the Services menu of all the Cocoa applications and in all context menu where a text is selected (see image).
There is a default shortcut associated with the service (Ctrl + Shift + Command + V – yes, I know, you need 4 fingers to press it…).
To be sure that the service is recognized by applications you may have to quit and reopen applications that was already opened when you installed it. A logout/login could be the best way to make the system recognize the service.

You can also change the shortcut associated with the service (the default is Ctrl + Shift + Command + V) going into the Keyboard Preferences -> Keyboard Shortcuts and selecting Services from the left column, in the right column, scrolling, you’ll get to the “Send to PasteFire” service.
The strange choice of the default shortcut is made to not conflict with common applications (Safari, TextEdit, Finder…).

To remove the PasteFire Preference panel you can right click on the icon in SystemPreferences and choose to remove it; remember to first uninstall the service.

You can find additional information on the sourceforge project page: http://pastefireclient.sourceforge.net/pastefireservice.html

Note: the service does not work in Google Chrome and the reason is that at this moment system services are not implemented by it….
