10.13.6 was the latest High Sierra update, so I thought you had something that depended on it and did not think to ask about upgrading to 10.14.6. Anyway, what's important is your problem is solved. OnyX is a multifunction utility that you can use to verify the structure of the system files, to run miscellaneous maintenance and cleaning tasks, to configure parameters in the Finder, Dock, Safari, and some Apple applications, to delete caches, to remove certain problematic folders and files, to rebuild various databases and indexes, and more.
1) If you can get to the TC drive (I think that it should be visible in Disk Utility) try repairing Permissions. I’ve heard that many times about Macs – they usually work well, but if they start acting squirrrely, repairing permissions is a good first step. 2) Try a utility like Onyx. Onyx is from France and is free. 2-in x 2-out USB Interface. Boutique-quality Onyx™ mic preamp with class-leading fidelity and dynamic range. +48v Phantom Power for use with studio condenser mics. 1/4” TRS input with Hi-Z switch for connecting guitar, bass, and more. High-resolution 2 in x 2 out 24-Bit/192kHz recording.

OnyX mac is an all-in-one system maintenance tool and optimizer. It is a very simple and light application that comes with a variety of maintenance tools that can be run to make sure that you are enjoying your system at its fullest.
The first scans that OnyX will make automatically when you run the application for the first time are a S.M.A.R.T status check of your hard drives and the analysis of your startup discs. If the application detects any problems, it will prompt you to carry out a reparation task.
Not everything that OnyX can do deals with hard drives, though. In the main window, there are five categories. The first one is hard drive analysis and restoration, but the following ones allow you to repair the permissions of your system (a common problem with Macs), clear your browser settings, cache, passwords, etc., delete application, user and system caches, and more.
An array of more advanced features is also available. Those allow you to hide or show volumes, repair discs, run custom scripts, among others. OnyX comes with extensive help and it even includes a glossary with the information about many tasks.
Although Macs are known for their stability and lack of errors, it can never hurt to have an application like this.
