High Sierra very slow Finder update I have recently formatted my MacBook Pro and installed High Sierra (v10.13.6). Ever since, although I do not have many apps installed, finder changes are shown very lately.. 

For example: I take screenshots With keyboard shortcuts, they appear on desktop after some MINUTES..
Or: I delete 100-150 files, they are still shown on finder window for some time, some of them without thumbnails.. 

Does somebody have the same problem?

Finder relaunch fixes everything. But I have to relaunch Finder after every change..

Here is a screenshot of finder after I deleted some files. See the last column where "the kind of file" is shown. The removed files are still shown, but without any kind:
There seems to be a problem with Finder's external sync (described in the thread on MacRumors).

This slowness was linked to 3rd party file sync applications (Google Drive, Syncovery, SugarSync, etc). There is no simple solution so far.

There is also a related Apple Communities' thread.
