How can I download and install an EA using MT4 on MacOS?

 
Hi guys. How can I download an EA using MT4 on MacOS? It asks to open it directly in MT4. Is it possible to download it first and then install the EA manually, instead of opening it directly in MT4? I used PlayOnMac to install MT4 on Mac. I found the program path in Finder, but when trying to download an EA from mql5 website, it asks to open MT4, that cannot not found on my Mac.
