I'm having some work done on my Mac mini next week, probably a HHD change. As part of my trouble-shooting process last weekend, I attempted to create a new user. Could not do it! I assumed it was simply part of my HHD/S.M.A.R.T. problem.
However, the recent TidBITS (1533) reports that the Security Update (and/or the Safari update) is causing problems when trying to create a new user. Here is a link to a report and an investigation by Randy Singer (a long time Mac expert):
Safari 14.0 + Mojave 2020-005 Security Update Causing Major Problems! This appears to be in the process of being corrected:
UPDATE #7 – 9/30 1:30PM – Apple just pulled both problematic updates!
Pulled from the update catalog
1. Safari 14.0 – Released 9/16 – 001-50026
2. Mojave 2020-005 Security Update – Released 9/24 – 001-50026
Added to the update catalog
1. Safari 13.1.2 – Released Today – 061-98246
This is Apple’s acknowledgment of the issue.
Anyone who has not installed the updates will now be safe. This also means that we should be getting an official fix!!!
Stay tuned!
