How can I remove the driver “BRESINKx86Monitoring” installed by old versions?

A device driver with this name could optionally be installed for “extended x86 sensor support” when you have been using old versions of Hardware Monitor on Intel-based Macs running an operating system between Mac OS X 10.4.6 and OS X 10.9.5.

When you upgraded such a system to OS X 10.10 or later, the driver was automatically deactivated. Although it has no negative effect on your system, you might like to remove the outdated driver files. This has always been possible with the menu item Monitor > Remove driver for extended x86 sensor support.

As of version 5.0, this menu item is no longer present. However, you can still remove the driver as follows:

  1. Ensure you are logged in as user with administrative rights.
  2. Use the Finder to open the folder Library at the topmost level of your system volume, and inside it, the folder StartupItems. If the driver is still installed, you will see the folder BRESINKx86Monitoring at this location.
  3. Drag the folder BRESINKx86Monitoring to the Trash. macOS may ask for your administrator password.
