  • Dear Macintosh User

    This issue is only OSx users. Other platform such as Windows, Linux are not related.

    • Notification
      Above OSx ver.10.4.1, irMagician can’t work on Apple’s CDC-ACM kext. Therefore, we use 10.4.11 kext which has been built on current development environment (as 10.9.2). Web-master has confirmed it works. However, could not guarantee 100%. Understand at your own risk to use.

      Detail of issue as below,

      1. Port open
      2. Write to port / Read from port
      3. Close

      After above, re-opne port then read / write. Not respond any.

    • Counter measure
      • Re-build 10.4.11 kext
        We recommend to replace re-built kext which has been released at OSx 10.4.1 to current kext.

          • AppleUSBCDCACMControl.kext.10.4.1.tar.gz
          • AppleUSBCDCACMData.kext.10.4.1.tar.gz
