From 3c1326a472ca67ff6159d644589ab5e5bfc1258c Mon Sep 17 00:00:00 2001 From: Mike Karels Date: Tue, 7 May 2024 17:09:06 -0500 Subject: handbook/virtualization: add note on workaround for Parallels A user reported high CPU utilization on a fresh install of 14.0 on Parallels (MacOS, M1/Apple Silicon).
