PDF Auto Update

iTeXMac manages external PDF file update. If you are currently viewing a file with iTeXMac built in PDF viewer and the file has been changed without iTeXMac being informed, iTeXMac can ask the user to update the PDF file rendering, letting him a chance to previously save a backup copy. This does not occur if iTeXMac itself initiated the change by launching a compile or typeset process for example.

Automatic PDF update is Enabled Disabled from the options View menu item
Smart update menu item controls whether the user will be left a chance to backup the previous version.

Limitation:
During typesetting or compiling, this automatic update feature is unavailable. It may cause problems when typesetting at the same time different files both from iTeXMac and the Terminal application. In general, there should be no problem at all.
