Short and frequent game freeze

I have an iMac 27’ late 2013 with the latest Mojave OSX. I upgraded RAM from 8 GB to 16 GB because I noticed that Hots keep almost 6 GB. The frequent freeze that slowed game and the long time occurred to close and open the game became shorter but still find short and frequent game freeze in mass heroes fight.

I hoped that the voice that improved compatibility in HOTS patch with latest mac osx could also solve the problem.

I am the only one? Is there any chance to solve it? Is there any plan to support Metal just like SC2 and have a full graphic support?

Thank you all in advantage for you answers :slight_smile:
