Library directory confusion for audio unit Components and suspicious files in Application Support on Big Sur
I'm having some difficulties understanding the correct pathways for both audio unit components and my sample libraries. The default pathway for installing my sample libraries was (/Users/Shared/) so I didn't change it. This shouldn't be an issue, right? I've had no problems thus far.
And next, I'm aware that there are 2 library folders that serve different purposes but I fear that there may have been a mix up or overlap of these directories at some point. One of the Components folder is empty (~/Library/Audio/Plug-Ins/Components/) while the other contains all my plugins (/Library/Audio/Plug-Ins/Components/).
While I'm not having any specific issues with the plugins themselves, I'm noticing some suspicious files with .winsecurity extensions in (/Library/Application Support/ctmp/). I've searched the web and the only familiarity was this thread: ctmp folder? - Apple Community However, Malwarebytes did not detect these or any files as malicious or threats so that thread's results were inconclusive. Also the ctmp folder cannot be found in (~/Library/Application Support/) if that matters.
It's possible that these files could be related to the licensing or security of a plugin/software that I use but that brings me to my final point of contention; My OS is failing to update from 11.7.8 to 11.7.10 (A security update) and from 11.7.8 to Monterey. I'm not interested in going to Ventura or Sonoma and I'd be fine staying at Big Sur but I'd like the security update at least. Thanks in advance, these problems have been baffling me for years.
