Is there any way to stop getting emails about this?

I posted the same error message to the most recent post " Dropbox won't start after macOS Monterey update"

DropboxInstaller.dmg doesn't even work on Monterey, it won't launch.

I've tried BatchMod, CodeSigner, DeQuarantine, and the usual sudo Terminal commands on it and still nothing, it won't launch even right clicking etc.

There's a real issue of Dropbox (not) running under Monterey environment.

[andreabonato]

Do you try this?

"This is a step by step sequences....!
1) by Activity Monitor (you find it in Launchpad-Others-Activity Monitor) search and select all Dropbox items (especially Dropbox Finder Extension) and stop by the :cross_mark_button: or X bottom on the top of the app;
2) by Force Quit (in the System Menu Screenshot 2021-10-29 at 09.50.19.png) refresh or relaunch Finder;
3) in System Preference-Security and Privacy-Full Disk Access (after clicking lock to make change in the bottom left corner), enable Dropbox.App.
4) I think is better to restart computer after that."

Bye.

1. Since the installer won't start, your method doesn't solve the issue on my end

2. Even after managing to install Dropbox through another installer, I've tried this many times, even (-) and then (+) Dropbox again, and restart of course, but this is not having any impact nor solving the issue on my end: Dropbox won't start again after each restart of the computer

yes, on the emails you get there's a Click here to unsubscribe link on the email footer, as with any mailing system 🙂

Hi everyone, with the macOS Monterey update (macOS 12.0 and above), some stricter permissions have been enforced by Apple which have probably led to the issue you are experiencing.
 

The following steps should help to resolve this behavior:

1. Click on the Apple icon in the top left hand corner of your screen
2. Select "System Preferences..."
3. Then "Security & Privacy"
4. Select the Privacy tab
5. Select "Full Disk Access"
6. Under Dropbox, ensure that all the folders are checked. (To make changes, you will need to click on the lock icon, and enter your macOS password)
7. Repeat these steps under 'Files and Folders' and 'Accessibility'
8. Once you've completed this, please attempt to restart the Dropbox desktop app

If need be, a reboot of the Mac itself would also help.

Please, @Jay and @Megan, read our posts. The solution you keep proposing does not work!

[shinbeth]

@Jay please stop repeating like a bot, we told you it's NOT working.

And btw even the Dropbox installer is not opening under Monterey, please re-read above I'm tired of repeating ourselves.
