Because I, before I decided to purchase this product, precious little information was found on whether the Converter with Apple's firmware (in my case: OS X Yosemite) is compatible, I want to write for those who a few lines, possessing an Apple product and want to digitize old audio cassettes. Caveat: It all works perfectly - if you know how! ;-) The package includes in addition to the tape deck, a USB cable, a user manual and a CD-ROM with software. Love Apple users, for the conversion you need only the cassette deck and the USB cable with which you connect the converter to the computer. Has proven to be Mac compatible - in my case - the supplied user as the software on the CD-Rom, which serves only the instruction for Windows PCs. Thankfully, Apple has its own devices with the software "GarageBand" feature. Because with this work converting outstanding. One has to proceed only as follows: 1) Open the program ;-) 2) Select the USB interface as a data transmission Choose Create 3) New project 4) Not to be irritated that the software thinks just play a guitar or another instrument that should be taken now - ie, to ignore the list of instruments and just take the first available instrument that is proposed. 5) Press PLAY on the cassette deck 6) Recording Press the program - the rest is done by GarageBand alone ... :-) When the recording is completed, there is also the possibility of providing the captured for iTunes. For this you simply choose "deploy" and follow the instructions - and you can already his beloved MCs in as I find very satisfactory quality on the iPod or wherever hear. Finally, a tip for transferring the data: if you put the little knob on the continuous symbol on cassette deck under the huge play button, you need not rotate the cartridge when side A is played - a very pleasant gimmick. Whether the quality of the digitized data under Windows with Audacity is so bad as some reviewers write here, I can not judge. Me personally, the really good quality that delivers GarageBand, very surprised. I can not judge whether or not the quality of music MCs when digitizing is so bad, how many times described, I also - have digitized only audio cassettes - as I said. All in all, I can recommend the LogiLink Digital Converter in conjunction with Apple products highly enough.
