Apple's mission to make the Mac safer is slowly destroying it

Pro

0. The one that's really annoying is the unblockable recurring popup Login Items notifications added by MDM.

1. The Systems Settings app is a disaster trying to merge the touch interface of iPad with the less direct interface of macOS. Selective PrefPane management is gone and you must weed through cognitive overload of dozens of options like it's Windows. The Settings app doesn't allow resizing, and instead is narrow and tiny.

2. Too many things are done for stylistic fashions rather than for functional improvements. Changing the look with every release is prioritized over fixing long-standing bugs or keeping longstanding useful features like network locations (which effectively doesn't work anymore because it drops connections).

Con

3. There's no way to oversimplify control and choice. If you remove that choice, then you end up with assumptions, violations, and willful ignorance. Security that isn't theater requires ratcheting up the posture to make undesirable behaviors more expensive while causing the least interference to legitimate uses. There is no free panacea.
