That will probably be lack of 64 bit on 5C - Apple pushing 64 bit or dual 64/32 bit apps. Ironic since the Roon developers were so against 64 bit - I gather preferring the smaller footprint of 32 bit - would be interested what got released in the end now they appear to have been freed from the limitations of supporting legacy Sooloos kit.
