I see a "Couldn't start Dropbox" error on my macOS 15.7.1.

Application Affected

Dropbox Desktop App Max
Device

M1 MAX MacBookPro
Operating System/Browser (if using the web)

macOS 15.7.1
Dropbox App Version (if using the app)

235.4.5905

Question or Issue

Dropbox will not let me open.

Ive tried uninstalling, re-installing advanced etc etc but nothing is working.

I recently opted out of file provider and went back to legacy for a few reasons and it worked.

maybe it updated in the background today but i havent for the life of me been able to get it to work.

Hey @Benjamin Gordon welcome back,

Because you've installed Dropbox multiple times and switched between legacy and file provider, can we start by confirming that you only have one version installed currently?

On macOS, open Applications and ensure you don’t have multiple Dropbox versions ( legacy + File Provider) that might conflict.

hi. i only have one version installed (235.4.5905).

Hey @Benjamin Gordon! I hope you don’t mind me asking, but can you zoom in the error log a little bit more and send me one more clear screenshot of it?

I’d like to go through it again and check if there’s something more we can try.
