I have an Imac G4 600 running Os 10.3 and a external USB1 LiteOn Lsc-24081MX DVD-RW. When I connect the burner the Imac does not see it. Toast says no recorder detected. Read a post on another mac forum that says that LiteOn drives just doesn't work on mac. But an other post says that this guy has a emac with the sameburner as mine and that it works perfectly. I'm VERY new to the mac world, so answers should be well explained, plz. Hope someone can help me

A concise follow-up to the thread for future readers and to tie back to and : burning software can only use recorders that the operating system actually sees. If the OS never enumerates the external unit, apps like Toast won’t be able to talk to it. The useful next step is to isolate whether the problem is power, the USB bridge/enclosure, or the drive mechanism itself.

Common, checkable steps that help isolate the cause:

  • Verify the unit on a different platform (a Windows or Linux PC) to see whether it powers up, mounts, or appears in Device Manager — if it works there the drive itself is fine and the issue is Mac-side compatibility or enumeration.
  • Try a different USB cable/port and a powered USB hub or the enclosure’s external adapter/Y-cable if it has one; many external optical enclosures need more current than an older Mac USB port supplies.
  • Capture the OS device list before and after plugging the unit in to confirm whether the OS ever detects it. From Terminal the commands below list USB devices and disks; compare output with the device disconnected and then connected:
    system_profiler SPUSBDataType
ioreg -p IOUSB -w0
diskutil list
  • If the drive never appears on any machine, the USB-ATAPI bridge in the enclosure or the enclosure’s power circuitry is the most likely suspect.

If the enclosure is at fault, common remedies are to use a different externally-mounted enclosure known to be Mac-compatible (USB2 or FireWire for older Macs), use a powered hub, or remove the optical unit and place it in another adapter/enclosure. Opening or modifying the enclosure can void warranties, so factor that in.

Because already suggested inspecting the system device list, the troubleshooting above focuses on practical isolation and repair options. For reliable burning on legacy Macs, prefer externally supported, Mac-marketed drives or FireWire/USB2 enclosures that explicitly list Mac OS compatibility.

Hello,

The website from LiteOn doesn't list Mac OS X as a supported operating system. While that may not necessairly suggest that it won't work, it doesn't shine to nicely on the subject. A lot of devices are cross-platform.

You can look into the System Profiler found on your system volume, and inside the Applications --> Utilities folder. See if the System detects it within there.

If you have another Mac around, you might be able to try it and see if the component works there. If not, you might need to wait around until OS X 10.4 and see if it is supported there.

Let us know,

Ok, tried to check the system profiler under USB, and only my mouse was listed. We have another Mac here, but it was the same story :-/ Tried to restart it and the check the /var/log/system.log but no trace of the LiteOn device.

Thanks for taking your time to help me :-)

Hello,

I think you are going to be out of luck. You might try seeing if the guy you read about who has it working on his eMac has contact information available. If so, write him and he might return back with some thoughts too.
