Hook Version 3.4.3 is now available for download and as an in-app update.

This release updates integration with

This release adds support for MarsEdit.

Update of database

When you first run Hook 3.4.3, your Hook database will be updated. Please allow the update to complete (as opposed to force-quitting).

Obsidian integration

Obsidian is a note-taking app that treats links as first class data objects. It stores your notes in local folders (“vaults”) that you can sync with various mechanisms of your choosing (e.g., Dropbox). It is an electron app; therefore, it does not have a macOS ‘look & feel’ and it does not have AppleScript automation. Hook sports a macOS-style user interface to manipulate links to Obsidian resources. We have worked with the Obsidian developers and community to enable you to link Obsidian notes to almost anything else 😊.

The new integration with Obsidian enables users to easily choose amongst three URL schemes: default (obsidian://), “Advanced URI” (obsidian://advanced-uri?vault=...&uid=...), and hook://file/.

The latter two schemes

  1. are more robust than the default Obsidian scheme. The links will work even if you move the note files around.
  2. however, they require installing the “Advanced URI” Obsidian community plugin.

You can switch between schemes for Obsidian using /Applications/Utilities/Terminal app :

  • defaults write com.cogsciapps.hook integration.obsidian.URL.scheme obsidian-default
  • defaults write com.cogsciapps.hook integration.obsidian.URL.scheme obsidian-advanced-URI
  • defaults write com.cogsciapps.hook integration.obsidian.URL.scheme hook-file

If you want to stick to the original scheme, you don’t need to do anything. Hook will continue to work with Obsidian as it used to.

FMail integration updated

Hook 3.4.3 updates integration with FMail, a free native Mac application for Fastmail.

The new integration enables users to use the standard (RFC-5322 compliant) ID of the selected email to construct hook://file/ URLs, instead of using the fmail:// URL scheme. That way, fmail users can email their colleagues links to emails that they can open with a large variety of Mac apps (and soon on iOS). Similarly, fmail users are now able to receive and open hook://email/ links received from users of Mail.app, Airmail, MailMate, and other email apps.

Drafts integration updated

Drafts is an app that jumpstarts writing.

We have updated the integration between Hook and Drafts to reflect the fact that Drafts 5 now utilizes drafts:// as its default URL scheme. Your old hooks to Drafts documents will remain visible in the “HOOKED” section of the Hook window.

In other words, you won’t notice a difference from before Drafts changed its default URL scheme for drafts.


Web browsers are not great environments for writing blog posts or managing content. Fortunately, Hook now supports MarsEdit, which enables you to write, preview, and publish your blog from an app rather than from a web browser. That is very consistent with Hook and Apple’s philosophy. (Web interfaces in contrast tend to suck.

bug fixes

This release also fixes an issue that could prevent a Hook update/upgrade license from being applied.

Eligibility for updates

Hook software updates are free to any Hook CogSci Apps customer with a Hook Updates license that was valid at the time the update was released. Hook Pro and Hook Essentials each come with one year of free access to software updates.

If your Hook Updates license has expired and you apply this update, please note that Hook will revert to Lite mode until you purchase and apply an Updates license. However, you can also revert to a previous version of Hook that was released during your Updates License period. Upgrading from Essentials to Pro includes an additional 12-month Updates license.
