If you installed it through brew, try running the brew list tesseract
In my case, it gave out the following addresses:
MBP-2:/ joantune$ brew list tesseract /usr/local/Cellar/tesseract/3.04.01_1/bin/tesseract /usr/local/Cellar/tesseract/3.04.01_1/include/tesseract/ (27 files) /usr/local/Cellar/tesseract/3.04.01_1/lib/libtesseract.3.dylib /usr/local/Cellar/tesseract/3.04.01_1/lib/pkgconfig/tesseract.pc /usr/local/Cellar/tesseract/3.04.01_1/lib/ (2 other files) /usr/local/Cellar/tesseract/3.04.01_1/share/man/ (11 files) /usr/local/Cellar/tesseract/3.04.01_1/share/tessdata/ (27 files)
The port and others should have similar commands.
You can always connect to the terminal and cd / && sudo find . -iname tesseract cd / && sudo find . -iname tesseract
