appMac, creator of wkiosk, announced a new version. This new version uses Apple Safari HTML engine, and is a free upgrade for customers of wKiosk 2. Version 2.2 is still available, and uses Gecko.
Wonder why they switched?
One should note it requires 10.3. So perhaps, they are utilizing the smaller package (no need to install WebCore, as it’s ships with 10.3). Unlike Gecko, which has to be included.
