Fix slow opening of your folders in OS X Yosemite 10.10.3

Since OS X Yosemite saw the light a few months ago, many users have been experiencing performance problems with their computers while others saw their Wi-Fi connection not working properly. The launch of version 10.10.3 It was the definitive solution to these problems, but as always, some are fixed and others appear.

Now we know that there is already a large group of users who seem to have been affected by another strange bug, this refers to the opening of folders being incredibly slow, that is, in many cases we will have to wait quite a few seconds before we can access your content. The same happens when activating any auxiliary Open or Save menu, something that makes the use of the system unsatisfactory, let's see how to fix it.

Unlike other bugs, this one is not particularly CPU intensive it just makes the system becomes unusually slow when loading previews of folders slowing down their opening. The daemon to blame for this failure is cloudd, which is associated with a set of metadata that may have been corrupted belonging to CloudKit.

At this point it is recommended to save a backup with TimeMachine as a precaution since we will delete system files. From the Finder we will press CMD + Shift + G to open a path box «Go to the folder» and we will introduce this path:

~ / Library / Caches / CloudKit /

Here we will see three files: CloudKitMetadata, CloudKitMetadata-SHM, CloudKitMetadata-wal. We will select them and leave them in the recycle bin.

Now the next step is to go to Applications> Utilities to start the activity monitor, locate the cloudd process and force restart it. We can also do it through the terminal by entering:

rm ~ / Library / Caches / CloudKit / CloudKitMetadata *; killall cloudd

With this we should have fixed the slowness error trusting that it is an isolated error and that other errors do not arise that give us more headaches.
