Solution: PiHole and high Mac CPU Usage, failed sleep on mDNSResponder

[CallMeCurious]

You may wish to review this thread as other Apple Users have been discussing issues along this vein, though I don't recall any concerns around CPU usage.

iOS 18.2 Mail push issue workaround: Is it better privacy-wise to whitelist mask.icloud.com and mask-h2.icloud.com or to put BLOCK_ICLOUD_PR=false in pihole-FTL.conf?

I’ve updated my Apple devices to 18.2.1, and removed the BLOCK_ICLOUD_PR=false setting, and restarted Pi-hole DNS. The Apple mail app appears to be functioning fine again for me.
