I just got an answer from MetaQuotes how to solve the problem. The MT4 needs to have the 1080 build and these are the steps to make this on a Mac. There are few steps to update:
You should open demo account on MetaQuotes-Demo server and log in. Accounts -> Open an Account -> click "add new broker ..." -> enter MetaQuotes-Demo -> click "Scan" -> select MetaQuotes-Demo -> click "Next".
Restart the terminal.
Wait until "LiveUpdate finished" record would appear in Journal tab.
Restart the terminal once again.
Check terminal's build.
