I believe your system has "old" awk. It can't understand "f in a" construction. Why don't you just try change awk to nawk ("new" awk)?

Where is an output examples. I can guess than from your input files you want to get this one line:

Why only 3 blank fields on non-matching lines (and four additional on matching ones)?
And do you need to keep the order of lines in mac_trans.txt or it doesn't matter?
