Recently I was handed over a HFS volume to read from my colleague who uses his Macbook exclusively. We had tried passing data through Bluetooth, but gave up due to some formatting that I hadn’t done yet on my 8GB MicroSD card on the CrackBerry.
So he handed me a USB key that was formatted as HFS.
Then I remembered, from way, way, back that I had a TransMac license key purchased for just this occasion. If you are ever in this situation, I recommend purchasing from TransMac by AcuteSystems. There are probably many software providers for this, but I was just saved thanks to a Trail License available here.
