How do I lock layouts
How do I lock Keynotes so that nobody can change my layouts and have Keynotes run as a self running presentation?
iMac, Mac OS X (10.6.8)
Keynote does not have that facility.
There is no secure method to guarantee what you want, if an image is visible it can be altered by software.
A workaround to prevent the average user from manipulating Keynote is to export as a Quicktime video; users can still edit the video, or export a PDF, that wont prevent users using Acrobat to change things.
