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.

Most of us do not delve into the bowels of macOS. Third party software will sometimes install all sorts of non-sense files, sometimes including files only needed for the Windows version of the software. A thread from several years ago indicates they may be related to malware where the user suspects it may have come from a DAW plugin.

As for the error message during the OS upgrade, try booting into Safe Mode before running the macOS Monterey installer. If this works, then you have some third party software installed which is interfering with the normal operation of macOS. Typical culprits are anti-virus apps, cleaning/optimizer apps, and third party security software. You can also run the third party app EtreCheck and post the report here so we can examine it for clues.


You can also try creating a bootable macOS 12.x Monterey USB installer & installing macOS from the USB installer. You will need to modify the laptop's security settings to allow booting from external drives by using the Startup Security Utility from Recovery Mode.


These 2018+ Macs can get very weird, so it is hard to say what this error may indicate because the T2 security chip can cause some very odd issues for simple things.

Is your data backed up? Documents, email, and license keys?


You may find it best just to wipe and start over if you have at least two distinct backups.

It could be that some old software you have installed has left some unwanted components behind.


When you uninstall software, if you don't use an uninstaller from the company in question, and only trash the application file, a lot of application support files can remain.


http://www.reggieashworth.com/ has a software called AppDelete that can look at any application dragged over it, and locate all the supporting documents strewn through the system and delete them together. This way, you know what you don't need is taken out.


The images you posted are way to small to read with any clarity to determine which files might be problematic.

Appreciate the prompt response!


My current setup is the result of a refresh install on a new computer after dealing with similar problems on a previous MacBook Pro 16inch 2019 which wouldn't update passed Catalina. All of the software I'm running is deliberately installed for this exact purpose. I have a time machine backup on an external HD and manually backed up all my Logic files to a different external HD so that's not an issue and I haven't needed to uninstall anything on this machine so far. I'm hoping someone has an intimate understanding of the Library directories and/or .winsecurity files on OSX.


Since this was a fresh install I'd like to refrain from doing that all again but I will definitely check out AppDelete as that will be very useful for me regardless, thanks for that!
