I think 'Adobe Acrobta Reader' or 'Adobe Acrobat Pro' is the best solution.
You can install Adobe Acrobat Rader via brew in mac os

    brew install adobe-acrobat-reader

Then you can open and edit pdf with input forms by adobe-acrobat-reader.If you open a exist pdf with input forms by adobe-acrobat-reader,you will see 'fixing  forms filed'message.
