Yosemite (10.10) Finder Freezes in Column View

Solution 1:

I was able to resolve my own issue, after finding Quicklook crashing finder in Mavericks:

Rename/remove the com.apple.quicklook.ui.helper folder in ~/Library/Containers. Logout/in or reboot, and the problem is resolved for me.

Solution 2:

What worked for me was deleting the folder com.apple.quicklook.ui.helper in ~/Library/Containers/, restarting my computer, running disk utilities, "Verify Disk Permissions", then "Repair Disk Permissions".

Solution 3:

The folder ~/Library/Containers doesn't seem to exist on my Yosemite installation, but it does on Mavericks.

This is what I did to make it work:

• Run Disk Utility
• Choose the partition where OS X is installed
• Click Verify Disk, if it fails run Repair Disk
• Wait
• Click Verify Disk Permissions
• Wait
• Click +Repair Disk Permissions_
• Reboot

It worked for me on five MacBook Pros running OS X 10.10.3.
