Slow Finder/File Picker after MacOS update
So I recently updated MacOS (the one that added the new Photos app) and afterwards my Finder was terribly slow to open folders. Also when I used the file picker, in Chrome for example, it took forever to go from one folder to another.
Fortunately I found a fix on the blog of #HASHBANG Productions. The problem is most likely a damaged database of CloudKit. If you remove it, it will be redownloaded and everything works again.
Just use this command in the terminal:
rm ~/Library/Caches/CloudKit/CloudKitMetadata*
Here is the full blog post. There are also comments under the post that found that the problems had to do with linked cache folders that are on a different hard drive.
