When using Mt4 on my mac it uses a lot of CPU usage, 30% constant. And I think this might be because Mt4 download insane amount of data, in 24h it downloaded close to 50GB. Yes! I have disabled "News".
The only thing I can think of that could come anywhere near that amount of data is extensive low time frame chart histories on a lot of different symbols.
