I just did a clean install and put in new hard drives on all my Macs, now running El Capitan.
I can't remember how to install these curves. There is no folder for the 9890 printer with K7 and I tried the 9800 folder and it doesn't work. Tried making my own folder and putting that in the Profiles folder and installing but no curves are being located.
I had no trouble installing QTR and it shows up fine, just no curves.
