Brand new MBP M1 Pro 16" very slow
I recently sold my 2019 MBP 15” and purchased the 2021 MBP M1 Pro 16”. It runs Monterey (12.5.1) 16 GB RAM, 1 TB SSD. The new machine is very sluggish. It takes 5-10 seconds to start any app - including native Apple apps. Some non-Apple but very widely used apps take a minute to start up. Even simply changing active windows on the desktop takes 5-10 seconds! This machine is awful. My older machine was WAY faster and more responsive.
SSD has 376 GB free of 995 GB capacity
I’ve run Clean My Mac X multiple times to clear caches, free up RAM, etc with no change.
I’ve turned on reduce transparency and reduce motion in System Preferences.
Activity monitor shows three processes other than the kernel_task using lots of CPU, although total CPU load reported (and graphed) is about 8% system, 12% user, and 80% idle.
mdsync 50-75% CPU
fileproviderd 40%
kernel_task 16-22%
backupd 6-35%
I’m seriously considering sending the machine back, demanding a refund, and purchasing another 2019 MBP w/o M1 or M1 Pro
