New in Jack OS X 0.84 (Nov 26, 2009)

  • Removes requirement to use Aggregate Device on Intel Macs. Also adds new "hog" mode, and fixes some server-related bugs.

New in Jack OS X 0.83 (Oct 13, 2009)

  • Version 0.83 is based on the latest Jack version (jackdmp/jack2 version 1.9.4) and is
  • now distributed as two different packages :
  • the regular one for use on OS 10.6 only. It adds Mac OS 10.6 (Snow Leopard)
  • support, including 64 bit operation of the Jack server when using the “64/32 bit” version.
  • Why is it called “64/32 bit”? Since the current JackPilot code has problems running in
  • 64 bits, it will always start the JackPilot application in 32 bit mode. JackPilot however
  • will start the Jack server in 64 bit mode. This will allow Jack to be set as the “Default
  • device” for the Mac (default devices on 10.6 require 64 bit operation, allowing apps like
  • iTunes, etc.. that only use the Mac’s default device, to be routed through Jack).
  • This version may cause problems however if you are using Jack OS X with a 3rd party
  • audio device (i.e. anything other than “Built In Audio”) that does not yet have 64 bit
  • drivers installed on your system (since the Jack server is running in 64 bit mode).
  • In these instances, if you are running OS 10.6, you will be forced to use the “32 bit”
  • version, and you will lose the ability to set Jack as the Mac’s “Default” device as above.
  • A “32 bit” package is also provided for users of pre-10.6 operating systems.
  • Please note that the Jack AU and Jack VST plugins are still 32 bit in both packages.
