Incredibly Slow Finder

[bobbydaz]

Same issue here. seems to be more noticeable since 10.10.5. If I drag image files across the screen when they go over open finder windows there is a slight delay and the drag is very jittery instead of smooth. I've noticed all apps are very slow to open a file. If i'm in InDesign or even Pages, when I open a file (small or large) there is a spinning ball for a few seconds before it will open. I'm on SSD with plenty of RAM so not sure what has happened.

A restart fixes it for a while but not for long.

Maybe a memory leak? It's not that bad for me. I generally don't have issues opening other apps. Only apps that are a touch slow for me is Lightroom and Photoshop. But I have a huge catalog in LR and Photoshop has to load all the presets. They are a lot faster than they used to be too.

How do you work out if you have a memory leak?

How do you work out if you have a memory leak?

Well you can check your activity monitor when you discover your Finder having issues. It will show you if a particular app or something it taking up a ton of ram which can cause your Finder to act up. I've seen this with certain apps. It might not be Finder causing the problem, it could easily be something else. I've seen the recent Photos app locking up certain things like emptying the trash until I close Photos app.

I'm honestly not sure how to fix a memory leak once you discover one. But once you determine a problem with a certain app, post your findings on here and see if anyone can help. I did have an issue with a different app in the past and I just uninstalled the entire app and reinstalled and it fixed the problem. Fixing parameters has helped me too with issues I've had, although many on here say its a needless task. As much as I've messed with things on my system it does help every now and then, but for the majority of users I can see why it's not needed. I'm not an expert. I've not had many problems really. I consider myself lucky. And any of the few problems I've run into is usually of my own doing. I don't tinker with things as much as I used to, so I generally have a pretty smooth system.

Good luck.

If the memory leak is due to Finder preview (e.g. quicklook), you may give it a try to disable it:
Finder>View>Show View Options: (uncheck "Show icon preview" and "Show preview column")



Then, see if memory leakage is reduced. (it is not a fix to the problem; a workaround only)
