MT4/5 on MacOS/iOS - can I run EAs, indicators etc

 

Hi all


As a mac user I'd like to learn what kind of indicators and EAs can I run on the desktop macOS version of MT4/5?
Can I buy any indie or a system from the market and run it on the mac version?

I downloaded iOS version and it is plain dissapointing, looks like something designed 50 years ago without any chance of customization. 

Thanks!
