how to remove CUDA driver from mac 10.14?

Un-Install fundamental principles:

• anything installed with drag-and-drop to the /Applications folder can be un-installed by Drag-and-drop to the Trash. After a restart, the Trash can be emptied.

• anything installed with a complex installer program requires the manufacturer's un-installer program. sometimes this is included as an "option" in the Installer package, but the software-maker's web site should specify how to un-install (if they don't, they get swamped with users clamoring for Un-install Instructions)

• anything claiming to be an 'uninstaller helper' is just JUNK. (worse than web site click-bait)

the un-installer for CUDA toolkit etc is a complex un-installer included with the original software download. this manual describes where it places its files, if you want to hunt them down individually instead.

check section 3.3 for Un-Install

Note that unless CUDA actual gets CALLED, it will not be loaded, so you CAN just ignore it is too much trouble to remove.

Consider downloading and running this little "discovery" utility, Etrecheck. it changes NOTHING.

it contains little tests for speeds of devices, CPU utilization, memory usage, energy usage and a digest of recent problems, in one easy to use package. it does not even need to be Installed.

if you follow the directions faithfully, its report (pre-laundered of all personally-identifiable information) can be "Shared" to the system ClipBoard, then Pasted into an Additional text window in a reply on the forums.
