Since the CCCrypt takes an IV, does it not use a chaining block cipher method (such as CBC)? This would be consistant with what you see: the first block is identical, but in the second block the Java version applies the original key to encrypt, but the OSX version seems to use something else.
EDIT:
From here I saw an example. Seems like you need to pass the kCCOptionECBMode to CCCrypt:
ccStatus = CCCrypt(encryptOrDecrypt,
kCCAlgorithm3DES,
kCCOptionECBMode, <-- this could help
vkey, //"123456789012345678901234", //key
kCCKeySize3DES,
nil, //"init Vec", //iv,
vplainText, //"Your Name", //plainText,
plainTextBufferSize,
(void *)bufferPtr,
bufferPtrSize,
&movedBytes);
EDIT 2:
I played around with some command line to see which one was right. I thought I could contribute it:
$ echo "Now then and what is this nonsense all about. Do you know?" | openssl enc -aes-128-ecb -K $(echo 1234567890123456 | xxd -p) -iv 0 | xxd
