so i just started all this custom DLC biz today and for the most part have everything working properly on my mac. almost all of the songs are working fine but a handful of them (most arctic monkeys songs i tried, 2 coheed and cambria tracks, and a couple others).

 

i did the exact same thing with these songs as everything else so I'm not sure why they're not showing up, they are definitely m.psarc files. 

 

surely someone else has had this issue? thanks in advance for any help.

I also use Mac, and sometimes the conversion could fail, or the original file simply not work. In those cases I try to convert again via Windows, and if that fails there is not much to do. I guess you could try to repackage the files again, but you'd need Windows for that, as the Mac version of the toolkit can't handle the packaging.

 

I haven't felt that as a very common problem though.
