Lost Your License Key?

Fill out this form and we’ll email it back to you in a flash. Note this only works for products purchased from our Zengobi web store, not from the Apple Mac App Store which has its own integrated receipt mechanism.

Looking for an Academic Discount?

With our new simplified pricing, we no longer have a separate academic store. Instead our new, greatly reduced prices are available to all customers.

Installing Curio on OS X

Downloading and Installation

  1. Using your browser, download Curio from the Zengobi website.
  2. Simply launch Curio from your Downloads folder and Curio will ask you if it should move itself to the Applications folder. If an existing Curio app with a different major version is already in your Applications folder then that app will be renamed to include its version number ("Curio 8") before the move occurs. Alternatively, you can manually drag-and-drop the Curio application from that folder to your Applications folder to install it.

Access to Contacts, Calendar, and Reminders

When you first launch Curio, OS X will ask if Curio can have permission to access your Contacts. OS X will then ask if Curio can have permission to access some system applications. First OS X will ask if Curio can have permission to access your Contacts. We use the Contacts framework to find out who "me" is, so we can populate your Curio project’s Resources inspector with your name and email to use as a default resource. We also use the Contacts framework when you double-click a dragged-in contact so we can launch Contacts and show that contact to you. That’s it. We do not scan your contacts for any nefarious marketing reasons or to send any contact information to Zengobi’s servers.

Curio can sync your tasks with Calendar and Reminders however, just like access to Contacts, you will need to give permission for this to occur.

Permissions for all of this can also be set via System Preferences > Security & Privacy > Privacy.

Curio Reader

With our free Curio Reader app, colleagues and friends can easily view projects created using either Curio or Curio Express.

Curio Reader offers a simplified, read-only environment, where users can browse projects with full support for searching, printing, mailing, exporting, and presenting as a slideshow. Curio Reader can be downloaded at no charge only from the Apple Mac App Store.

Please note, however, that users will have read-write access to any embedded assets, unless locked using OS X permissions, found within the project. In addition, due to App Store-related sandbox limitations, Curio Reader cannot access aliases to external documents stored within the project or launch AppleScript figure actions.
