I’ve been keeping an eye on the cpu spikes and I assume it will do this for a day or 2 while it is indexing but should return to a nice idle once all of that is over. Fingers crossed. I really like dark mode. And performance feels about the same as 12.4.1. So far I’m a happy camper. Glad I waited till 13.2. Oh and my mail app seems fine but I don’t use push at all or fetch. I always have been a manual refresher to save battery.
