Helix and macOS 10.14 (Mojave) Compatibility
Introduction

With the September 25, 2018 release of macOS 10.14 (aka: Mojave) Apple has continued to deprecate (shut down) older macOS technologies and to merge the visual interface of macOS and iOS. (If you care for a detailed analysis of the changes in Mojave, read the Ars Technica review.)

In places where Mojave changes control elements, such as checkboxes, popup menus, and radio buttons, Helix reflects this new design style, making your collections ‘fit right in’ in Mojave with no (or only minor) design changes required.

However, the new ‘Dark Mode’ introduced in Mojave is not currently supported. You can use Dark Mode on your Mac, but Helix will not reflect the new look. We expect to address this in a future release.

Helix 7.0.4, released on January 1, 2018, is mostly-compatible with Mojave. Mojave compatibility issues discovered in Helix 7.0.4 will be noted on this page. (Older versions of Helix will not be tested or supported in Mojave.)

This technote will be updated as the situation evolves. (Last update: September 26, 2018.)

Mojave Notes
32-Bit Compatibility 32-bit

Helix started life in 1983, when 32-bit applications were all that existed on Macs. Now Apple has announced the coming end of support for 32-bit applications, requiring that all applications running in macOS 10.15 and later be 64-bit. This transition requires a significant amount of work on our part, work that is currently underway.

Beginning with macOS 10.13.4, Apple started displaying a dialog box — shown at right — when a 32-bit application such as Helix was first launched. This warning continues in Mojave and, as with High Sierra, it can be dismissed and forgotten for now.

Users who wish to upgrade to macOS 10.15 will need to upgrade their Helix applications when 64-bit versions are released.

Dark Mode

Helix 7.0.x does not support Dark Mode in Mojave. this does not affect usability; it is a cosmetic annoyance we expect to address in a future release.

Helix Client

Helix Client’s Connection window and Open Recent menu do not show previously established connection documents. The workaround for this is to open the connection document (found at ~/Library/Application Support/Helix/Client) directly.
