My Mac has been rock solid with V9 since the start, with no graphics or CPU glitches. However, having just updated to Sierra, I’m having CPU spikes.
I’ve discovered that turning off ASIO guard pretty much resolves the issue, but this was no problem on previous OS.
I was forced to upgrade since I was having issues with Izotope software, and they advised the only solution was to upgrade to Sierra.
Any one else had similar issues?
