The current version Dialectic has been tested on and is compatible with Mac OS X versions 10.5.8 - 10.9 (Mavericks). For 64-bit compatibility, Dialectic must be run on a Mac OS X 10.6+ system.
Running Dialectic on OS X 10.8+
The first time you launch Dialectic on OS X 10.8 (Mountain Lion) or 10.9 (Mavericks), you may see a dialog indicating that Dialectic is from an unidentified developer and, depending on your Gatekeeper settings, the OS may refuse to launch the application. If so, Option-click or right-click on the Dialectic icon in the Finder (not the Dock) and, from the contextual menu, select “Open.” Then, if further prompted that this item is from an unidentified developer, allow Dialectic to open by clicking the "Open" button. Once you allow Dialectic to launch the first time on OS X 10.8 or 10.9, you only need to double-click its icon in the Finder again to re-launch it.
In addition, there are many places from within Dialectic where it will access your Address Book data (i.e., from the AB Menu, from the Lookup, etc.). If prompted, you should allow Dialectic access to your Address Book data (contacts). Once you allow Dialectic to both launch & access your contacts, you should not need to change these settings again and will be able to use Dialectic as you normally would, including using the Address Book Plug-In and other features.
Analog Modem Compatibility & Mac OS X 10.7+
Apple has discontinued the Apple external USB modem and, as of Mac OS X 10.7 (and continued through Mac OS X 10.9), this modem is no longer supported by Mac OS X, even when using the 32-bit kernel. This is a limitation set by the OS that Dialectic cannot overcome, this modem is simply not supported on systems running Mac OS X 10.7 or newer. (This modem will also not work on Mac OS X 10.6 with the 64-bit kernel but using the Mac OS X 10.6 32-bit kernel will allow the modem to function properly.)
While the Apple external USB modem is no longer supported, there are other third-party analog modems that continue to work with Mac OS X 10.7, 10.8 & 10.9 using the 64-bit kernel. The USRobotics USR5637 56K USB FaxModem and the Zoom 3095 USB Mini External Modem have been tested with Dialectic on Mac OS X 10.7, 10.8, & 10.9 using the 64-bit kernel. We have also tested several generic USB fax modems (found online for around (US) $10.00 (e.g., USB fax modem 1 and USB fax modem 2)). All of these modems work with Dialectic for dialing and incoming call detection out-of-the-box without installing any additional software — or even the need to restart Dialectic. One caveat to using a third-party USB modem is that they do not route the modem audio through the Mac so you cannot monitor the modem audio even if this option is enabled in the Dialectic Modem Dial Method configuration nor if you use a custom init string to enable the modem audio.
When using an external USB modem, attaching the USB modem to the USB port of an ADC display or to an external USB hub, even a powered one, is not recommended. These modems work most reliably when connected directly to a USB port on your computer.
Dialectic Contextual Menu
With the introduction of Mac OS X 10.6 (Snow Leopard), Apple changed the way Services & Contextual Menu Plug-Ins work. Accordingly, Dialectic now includes a separate Service workflow which will be installed in your Services folder if either (or both) the Dialectic Services or Dialectic Contextual Menu Plug-In are enabled. This Dialectic Service workflow will automatically add a contextual menu item named “Dial Selection with Dialectic” when you select text and Control-click (or right-click) on it. Selecting this menu item will, of course, send the selected text to Dialectic to dial. If you have a large number of text-related Services, this menu item may be included in a Services submenu of the contextual menu.
For enhanced contextual selection dialing, we offer many application-specific extensions and plug-ins (e.g., Safari, Firefox, Address Book, etc.). In addition, there are scripts and other resources for dialing directly from additional third-party applications (e..g, Microsoft Entourage, Outlook, FileMaker Pro, etc.) available for free from the Dialectic resources page:
