ISub Problems with Intel-based Macs and OS X Tiger/Leopard) iSub Problems (w/workaround) with Intel-based Macs in OS X Tiger/Leopard Posted: 3/16/2007 (later w/iMic workaround) Updated 6/2/2008 for Notes on OS X 10.5.3 w/iSub Updated 8/31/2010 for OS X 10.5.x patch/fix iSub/PPC Macs Patch for OS X 10.5.x I'd forgotten about this older page (not much talk about the iSub for some time) but here's a reader note recd in late August 2010. Note back in 2008 a post here (see below) has notes about PPC workarounds, etc., And an iMac G4 owner here back in 2008 saying 10.5.3 fixed the problem (See June 2nd, 2008 news page post, but the Intel-based Mac iSub Problem remained. 'Subject: iSub fix for Leopard/PPC Hi Mike (or Ed?) I just dug my 20' iMac G4 out of storage, set it up, hoped the iSub would work, no dice. ( what OS version are you running?) Googling found a fix that involves downloading a package of drivers and a shell script to install them. Apparently this works with everything but iChat.

( G5 tower owner running 10.5.8 per Sig. No link in that thread page link, but earlier thread page has it - same as below) -Kira' That download page notes PPC Macs, so I assume there's still no fix for Intel-based Macs, unless Rosetta helps? ( Older posts follow) OS X 10.5.3 Update Note: An iMac G4 wrote that the OS X 10.5.3 Update (released May 28th, 2008) fixed the iSub problem with earlier versions of Leopard - but still not working with Intel-CPU Macs. I tried an old iSub here with my AL iMac running 10.5.3 - no sound output - although it did produce some sound (very poorly) with my G5 tower running 10.5.3. (Ref posts in the.) (Note: previous posts from OS X 10.5 users noted even PPC Macs had no iSub support in Leopard.) The original article from a reader mail in March 2007 (re: OS X 10.4.x/Tiger) follows: 'Apple Has Decided To Discontinue iSub Support For All Intel Macs I had submitted a few bug reports regarding the lack of iSub support on, initially my Intel iMac, and as time went on, all of my Intel Macs. Summary: The Harman Kardon iSub is not working on Intel Macs without the use of other USB audio hardware. Download buku teknik sipil.

Steps to Reproduce: 1. Plug in iSub. Check Apple System Profiler. Device is listed in Apple System Profiler, but does not work, and does not have separate volume control Expected Results: Expected iSub to work in conjunction with internal speakers, or with external non-USB speakers, as it should.

Actual Results: Device is listed in Apple System Profiler, but does not work, and does not have separate volume control Regression: This bug does not occur on PowerPC based Macs, just on Intel based Macs. Tested on a Power Mac G4 400 Sawtooth, Power Mac G4 867, Power Mac G5 Dual 2GHz, Intel Mac Mini 1.5GHz Core Solo, Intel iMac 20' 2.0GHz Core Duo, Intel MacBook Pro 17' 2.16GHz Core Duo, Mac Pro Quad 3GHz. Workaround: Attach another USB audio device (sound card, USB headset) and select that for sound output. The iSub and it's volume control will magically appear. Once you select Internal Speakers or another non- USB output, the iSub and it's volume control will disappear, and will cease outputting audio.
