Hey pwnstar,
I have the same issue with HS on my Mac, I’ve created this Thread a day ago.
I did not try Battleground since the patch 19.0.0, but I can say that playing multiple Ranked/Duel games in a row make my fans running high speed.
I have to close mostly all other application to play HS.
But from what I’ve seen, the Journal is the worse issue, as it trigger the CPU usage with no reason.
May I suggest you to install either Fanny or MenuMeters on your Mac, and set it to display the CPU temperature?
This will give you a good idea when you reach the high CPU temperatures.
Fanny can also provide you the targeted Fan speed.
My advises:
- Reduce all other Apps on your Mac
- Avoid to play long games (this may include Battleground)
- Keep an eye on the CPU temperature and FAN speed.
- When it’s too high, just take a break on the menu for couple of minutes, to let your CPUs cool down.
- And the most important, NEVER open the Journal before to play, CPU will get so high, that you will have to wait before to play.
I hope you will be able to play some games, and that Blizzard team will fix the Issue ASAP.
