I'm not an expert but I just successfully edited sections in a CDLC for the 1st time in my life so I'm feeling confident. you may have to convert your CDLCs to the Mac version since the majority of the CDLCs are uploaded as PC versions; so you might want to use this: https://www.rscustom.net/ (v2.6.0.0 worked perfectly fine for me, have not yet checked the newer ones) you can also use any other shop DLC instead of "Cherub Rock" with this just in case I'm preaching to the converted here: sry, just trying to help ¯\_(ツ)_/¯
