What to Do When Mac Finder is Slow or Not Responding?

Mac Finder not working issue

So, are you experiencing this weird issue with Finder on your Mac? It’s super slow to open folders, sometimes not responding, even worse, it keeps crashing randomly.

This kind of Mac Finder problem is frustrating. And lots of fellow Mac users have reported this issue after updating Mac to latest macOS.

Fortunately, it is generally an easy fix as long as you pinpoint the culprit. However, the process may not be as easy as it sounds. Sometimes it’s much time-consuming identifying the cause rather than resolving it.

In this article, we are going to show you a few common reasons and fixes to help you tackle the Finder problem.

Note: to make it easier for you, we break down the solutions into two situations (see below).

Situation 1: Finder Is Slow But Still Usable

This scenario applies to those of you who can use Finder to open folders or access files, but the process becomes much slower than usual. Here are the common causes and solutions.

1. Your Mac Is Running Out Of Storage

In general, it’s a good practice to make sure your Mac disk has at least 20% free space available to use. Otherwise, your Mac may suffer performance issues. To check storage usage, click on Apple logo on the top left of your screen, and select About This Mac, then click Storage tab. Here you get a quick overview of the storage via the colorful bar.

How to fix it: if your Mac doesn’t have enough storage, the easiest way to free up more disk space is by using CleanMyMac — an app that helps we Mac users quickly detect and remove system junk and unnecessary files.

We also recommend using CCleaner to locate those large old files and delete those you don’t need. You can also use this app to find duplicate files if you are used to storing multiple copies of backups and photos on your Mac.

Bottom line? Clean your Mac as much as you can to reclaim more free disk space, as this helps improve the overall performance of your Mac. Plus, the Finder slow issue can disappear too.

2. Spotlight Is Indexing

This usually happens when your Mac has updated to a newer macOS (e.g. 10.13 High Sierra). Other times when you just finished transferring a large number of files from an external drive to your Mac. In this case, the Spotlight often needs to index all new files for you to search. However, the process usually takes quite a while to complete. During the Spotlight indexing process, your Mac is likely to run slowly, heat up, and the Finder app will lag as well.

How to know if Spotlight is indexing files? Just click the search icon on the top right corner, type any file name, and see if there is an “indexing…” status message showing up.

If you don’t want to wait, you can either turn off Spotlight or exclude some items from indexing. Learn how to do that with the step-by-step instructions MacObserver introduced.

3. Problematic Finder Preference Files

In some cases, the preferences files associated with the Finder app could corrupt or break — causing Mac Finder to misbehave. To fix that, the best way is to delete Finder Preferences.

How to do that? Follow these steps…

Step 1: Search “~/Library/Preferences/” in the Spotlight bar, and click the “TOP HIT” result to open the Preferences folder.

Step 2: In the new window, locate this file “com.apple.finder.plist”, right-click and select “Move to Trash.”

Step 3: Now close the folder and restart your Mac.

Note: It’s harmless to delete a .plist file because, after reboot, your Mac will regenerate the Finder preference file itself.

Situation 2: Finder Is Completely Unresponsive

This scenario is best for when the Finder app on your Mac is not responding or becomes inaccessible. You’ll have to operate via Terminal command to delete the preference file to fix it.

Here’s a step-by-step guide:

1. Open the Terminal app. You can either do a quick Spotlight search or find the app under Applications > Utilities and open it.

2. Delete the primary Finder preferences file. At the Terminal prompt, type the following command exactly as written and press Return key on your Mac.

rm ~/Library/Preferences/com.apple.finder.plist

3. Now restart your Mac for the change to take effect.

In general, we don’t recommend you do so on your own if you are not comfortable using the command line. It’s best to have a geek friend assist you during the process because any misoperation could cause unexpected issues.

Final Words

The Finder not responding issue can be very annoying as we are used to relying on the app to access files and folders. But the problem does happen now and then, particularly when you just upgraded your Mac to a newer macOS version.

By the way, if you are new to Mac, learning about the Finder will help you better organize and manage your Mac files. Check out this Apple support article for more information.

We hope you find the above troubleshooting guide helpful and hopefully you have fixed the problem. If you have any questions regarding the issue, leave a comment and let us know.

Also my office 365 apps are very slow in opening and in many cases I get a message that it is not functioning and to force quit. Are there any corrections to be able to access my folders in finder. I have most of my information saved in dropbox that I access through finder. Help please! Very frustrating!

  5. i keep getting the respond
    rm: /Users/og/Library/Preferences/com.apple.finder.plis: No such file or directory

    in my terminal prompt

  6. I had tried many things, it was super slow driving me nuts on High Sierra. Your delete preferences file in the library really worked. The Dr. Cleaner is no longer available, just FYI, I didn’t feel like spending $35 for Clean My Mac. Thanks!

  7. My finder is unresponsive . Tried to delete the plist file using terminal and it say “No such files found” and my desktop icons are not there either . Also it is constantly loading (the rainbow circle that rotates) .

  8. This works. I’ve had a new MacBookPro for 6 months, (now its 2019) and native apps like Keynote and Preview kept freezing. I found hundreds of old plists dating back to 2011. I deleted all from 2011 through 2016. Restarted. Seems much more stable and faster!
