I use a slow cellular connection and noticed some apple service (I could never figure out which one, even after installing an outgoing firewall) was aggressively uploading some large blob every time the mac woke from sleep, which made the whole connection useless for up to half an hour.

At some point, apple must've fixed this "bug", but the experience -- and apple's increasingly obtrusive software -- convinced me to switch to linux.

My Macbook used to grind CPU for 10-20 minutes after every power on. That happened with literally fresh install and it does it every time. I don't know why does it do that. May be some indexing? This lack of transparency was one of the reasons for me switching to Linux too. I don't want my OS to do anything at all in background, that I didn't explicitly configured to. I want to be in full control of my software. Linux is far from perfect, but much better.

Huh, which process was doing this grinding on your MacBook?

In my experience this is usually Spotlight indexing files/checking previous indexes etc. If you have any backup software running that will do it too.

Generally it's mds_stores, but sometimes there are other ones which I don't remember atm. But mds_stores is the biggest offender.

Lack of transparency is almost a feature for these systems, and definitely something that serves the vendor, not the user. My daily driver is a Linux for the same reason - there is just so much less bullshit going on, and if I want to find something out, I can.
