Some of these issues, like the corruption, is probably due to having 3rd party kernel extensions enabled. One of the pop ups shown even shows that explicitly. I had the same issue for a raid controller app. That needs to be updated on the new machine hardware by holding the power button and changing to reduced security to enable the kext loading.

If someone installed apps with kernel extensions, disabling enhanced security on the hardware, then Id argue they should be competent enough to understand the issue, so the article is a bit disingenuous on that front.

Additionally, things like Apple ID for iCloud login require re-logging with 2 factor, again because the hardware has updated.

So there’s probably a cleaner UI model here that could run the user through all of these side cases, but it’s not as simply as copying app permissions (all of the unix level file permissions remain intact already)
