Macintosh Issue

@cogitoxin:

LC works perfectly in Windows 10 64bit. I can only guess that your Macintosh does not support submitting 'calibredb' via a spawned operating system subprocess using the particular Python parameters that LC uses.

Essentially, the above is what your attached left error-dialog message says. Your right error-dialog message says that since there "was a left message", you must create the custom column(s) manually.

Obviously you must first delete any custom columns that might have been created by LC, if any. Exit from Calibre, then Restart Calibre. Then, add whatever custom columns you have selected in the LC Configuration dialog. They must be simple "text" custom columns, and the #names must be identical to the #names you specified in the LC Configuration dialog. Exit from Calibre, then Restart Calibre.

Next, test your work by manually adding, changing and deleting DDC/LCC values using Calibre's 'Edit Metadata' function for custom columns.

Finally, bear in mind that just because you have an ISBN does not mean that it is a 'good' ISBN from the perspective of deriving DDC/LCC codes. You can manually derive (or attempt to derive) problem ISBNs using http://classify.oclc.org/classify2/a.../classify.html .



Good luck.
