Unable to start Dropbox

[RamseyM]

Hello

After restarting my MacBook Pro I find that Dropbox won't start.

This was the error message:

Until now it's been working just fine. Any suggestions would be most welcome.

Thank you

Hi @RamseyM, thanks for bringing this to our attention.

What version of Mac OS are you running on your device?

Have you recently upgraded the OS?

This will help me to assist further!

hello Jay

Thank you for reaching out!

I'm using MacOS 12.1 on an early 2015 13: MacBook Pro.

I seem to remember the machine did a software update some time in the last 10 days, but it had been working well after it.

By the way, I went through the process of launching Dropbox app, and got as far as pressing on 'Fix Permissions' but every time I did that the pop up window telling me Dropbox wasn't working came up and I was then unable to quit the app.

Helpful?

Glad to hear it worked out. Enjoy your week ahead!
