The installer can’t create the new filder “/var/folders/kt/

Launch the Terminal application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.

Drag or copy — do not type — the following line into the Terminal window, then press return:

ls -Odel $TMPDIR

Post any lines of output that appear below what you entered — the text, please, not a screenshot.

Back up all data, then enter the following command in the same way as before:

sudo chown -R $UID $TMPDIR..

You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you don’t have a login password, you’ll need to set one before you can run the command.

I don't know.

Thank you very much Linc! I have been trying to find a solution to my problem as well and your solution soved it!

This helped me too on my Mac Pro (2006) Thanks Linc Davis!!!

Hi Linc,

I've been getting this error message Lightroom cannot start because it cannot create files in the temporary file location “/var/folders/lK/lKbPbq2OF0aPCbMnDc erE TI/-Tmp-”

I've also been getting others errors about cannot create or modify temporary files when trying to install other programs. Also some of my documents on my computer will not open and crash.

Any help would be helpful.

I've tried doing this as read not sure if it helps:

ls -Odel $TMPD

This is what I had in response:

drwxr-xr-x 36 root admin - 1224 Dec 9 00:29 /var/folders/lK/lKbPbq2OF0aPCbMnDc+erE+++TI/-Tmp-/

This just worked for me too when I got the same message installing software on my older macbook. Thank you so much!
