10.12.5: Now the Finder is quitting

Two things are now happening on an iMac since I installed 10.12.5:

1. The Finder is often quitting.

2. The color wheel is spinning more

Booting into recovery mode and running Disk Utility hasn’t helped.

Back up your Mac if you have not done so already. To learn how to do that please read https://www.apple.com/support/backup/. To learn how to use Time Machine read Use Time Machine to back up or restore your Mac. The reason for creating a backup is that the symptoms you describe could be indicative of an impending hard disk drive failure, so securing your data is a primary concern.

Then, shut down your Mac and restart it in "Safe Mode". To learn how to do that please read Use safe mode to isolate issues with your Mac - Apple Support. Compare how your Mac works in Safe Mode to how it has been, and describe your observations in a reply to this Discussion.

Then, restart normally. If the same problem returns, please read the section If an issue doesn't happen in safe mode for Apple's recommended actions.

Finally, you can temporarily create a new User Account, and log in to that account to determine if the problem also exists when logged in to that Account. To learn how to do that read How to test an issue in another user account on your Mac. When you are finished troubleshooting, you can remove the temporary User Account by following these instructions: macOS Sierra: Delete a user or group. Before removing it, confirm you don't need any of the files you might have created in that Account.

Let me know what you determine.

I am having the same issue after updating my OS. rebooted in Safe Mode.  still getting message saying "finder quit unexpectedly". can't open anything. 

Might be a corrupt .plist.

Do a backup, preferably 2 backups on 2 separate drives.

Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J.  When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder.  Select Library. Then go to Preferences/com.apple.finder.plist.  Move the .plist to your desktop.

Re-launch Finder by restarting the computer and test. If it works okay, delete the plist from the desktop.

If the same, return the .plist to where you got it  from, overwriting the newer one.

Thanks to leonie for some information contained in this.
