Are you unable to log in to your MetaTrader 4 or MetaTrader 5 platforms on your Mac?
The most likely reason for this is the latest update for Mac - Catalina OS. Catalina’s 64-bit OS is incompatible with MetaTrader 4 and MetaTrader 5 programs which require Wine 32-bit to run. Currently, there is no Wine version available for MT4 and MT5 in macOS Catalina.
If you have already updated your mac, we advise you to revert your OS back to the previous version to enable you to run MT4 and MT5.
