Mavericks files / directories in finder slow showing up

This definitely has fixed or at least spend up the Finder. Adjusting the Scrollbar behavior as mentioned by azamino

STILL having the problem after the SnaggleTooth fix and upgrading MacBook Air 2013 to 10.9.5. Can take minutes for a directory of 150 files to appear! Or to copy files, though that slowdown seems less frequent. The only fix that seems to work is force quitting the Finder, in order to get to my files :/

On a side note, I just tried downloading the latest xCode which failed after 99%, so perhaps it's something wrong with the machine.

+1 here - iMac 21.5", i5, 8 GB RAM bought in March 2011, since I installed Maverick (actually I am running 10.9.5, coming from 10.7.x through 10.8.x) everything slowed down to death and I too had the impression that some files were deleted, so SLOW it is to read them, not to talk about external devices (CD, usb pens etc) - also when attaching files to email or other programs everything is very very slow and takes a whole lot to complete.

Apple, maybe this is not a critical update, yet something that many many user endure with great dissatisfaction... I'm sure this is NOT so hard to fix.. please!

Zapping the PRAM (option-cmd-P-R) seems to have cleared it up for me.

Ok so yosemite seems to have sorted this out... and then some. Loving the integration with the iphone - calls coming to the computer and texting from chat. Nice upgrade!

I have been battling this bug since 10.9.x (several versions). I am on 10.10.1 on a iMac (27-inch, Mid 2011) with 8 gig of RAM.

I have tried most of the "fixes" mentioned in the threads and I STILL have the problem.

Am about to try the PRAM "fix" next.

Zapping the PRAM made NO difference. I have to wait 18 seconds for any new window to open from a disk object. This is long enough for the Force quite window to briefly show "Finder (not responding)" just before the window actually opens.

How does it behave in Safe Mode.

Exactly the same behavior in safe mode.

Also persists after deleting OS and upgrading to Yosemite!

I had these same sort of issues and tried everything. Turns out it is a known issue and Apple has a replacement program for the bad video card in many iMac models. The bad card causes grey screens, black screens, sleep issue, hard drive slowness, system spins, kernel panics, and more! Wow, all fixed at no charge at my local Apple Store!

I did the re-indexing, and it definitely speeded up the populating of the Finder screen. THX!

Just came here to say Snaggletooth_DE's fix saved my life. >sigh of relief<

I have been having the same problem described on this post. I tried the workaround suggested by Snaggletooth_DE on this thread with little improvement (if any). However, recently my problem seems to have gone away, and I want to share why I think that is.

I develop a software package single-handedly, so I had never taken the time to worry about source code control. Instead, I was branching my source trees into different versions after each major number upgrade. Each parallel branch had literally thousands of files, all in the same sub-directories with the same names. By the time I moved to Mavericks, I had four parallel branches. I think this is what was blowing the mind of the Mavericks Finder.

Recently, I had occasion to move my source files into a git repository. To do it, I committed all the branches in stages into the repository, archived them (in zip files) and deleted the branches. Now I just have one branch with my files in it. And suddenly I am seeing no more Finder issues.

EDIT: I should add that I only saw the spinning ball issue when I was navigating inside the parallel branches. In other folders I never saw it.

I had to go back to Mavericks after I was having major issues with Yosemite (March 2015). And then the Mavericks update happened . . . and no response with my finder, no files showing. Went through the posts on this thread. Your suggestion for turning off Bluetooth was the key for me. I didn't even realize it was on (I'm still tweaking things as you always do when redoing the system). Thank you, thank you, thank you!
