After updating Mojave to 10.14.4 two days ago I've got some weird bugs with working with files. Finder doesn't see pictures created by Photoshop. Webpack-dev-server doesn't see changes in files. What happened? How to roll back to version 10.14.3?
The first thing I try when this kind of thing happens is to re-boot into Safe mode, then re-boot normally.
I find these aberrations don't last, especially after performing the above. Sometimes you can re-install the update to cure it.
