Just took my computer home from work this evening, as I do often. Never had any issues with opening up Lightroom but this is the message I received:

Lightroom cannot start because it cannot create files in the temporary file location “/var/folders/fy/10cdg0nj7_370vvhpt6cwk5h0000gn/T”.

Lightroom needs to be able create temporary files in order to operate correctly.

Won't open. Any insight anyone? Can't seem to find the question answered in any of the forums. Not very techy so I'm hoping there's a simple solution for this. Please advise. Thank you!

Are you using Lightroom or Lightroom Classic? Do you have plenty of space on your hard drive? Any chance your permissions changed? Maybe you logged in with a different user credentials. Did you update your system recently? What operating system do you have?

Provide as much information as you can. That will help us help you.

The second question. Too much on the hard drive. Deleted old photos, restarted it, and boom. All good. Thank you for the fast response.

Having the same problem:

Lightroom cannot start because it cannot create files in the temporary file location

C:\Users\[username]\AppData\Local\Temp

"[username]" being the name of my Windows user.

I have plenty of hard drive space.

I checked the folder and parents and made sure there were read/write permissions.

I am using Windows 10 64 bit.

I am logged in as an Admin.

Attempting to use "Lightroom the cloud-based photo service".

Check Preferences in CC, but I don't have an option to change or specify which folders Lightroom uses to create files - this is by default, immediately after installing.

I also ensured that I selected "run as an administraotr" when launching CC.

I would post as a new question, but I cannot find a link to let me do so.

I tried this link and it just takes me back to this thread. I am having the same issue. Windows 10 64 bit. Logged in as admin plenty of room on the hard drive. Even created a folder in the TEMP folder called Lightroom. Uninstalled and reinstalled and got same message. So here I am trying to do edits and I can't do anything until this is resolved. Thanks for any help!
