Hi! I had installed the security update 2020-005, which slowed my Mac to unbelievably low levels so I had to restore using a snapshot. It took my Mac back to just before installing the security update and now it's working fine.
I've noticed that there's a supplemental update, but the security update still shows in the updates list. What should I do? Install both? Neither?
