"Dropbox needs to change permissions" message on startup
Lately, every time I start my Mac (OS 10.14.6) I get a message that reads (in full):
"Dropbox needs to change permissions for the Folder: /Users/[name]/Dropbox
Enter your password to allow this"...
Hi Rachel R.2,
Can you try following commands in terminal:
sudo chflags -R noschg "/Users/$USER/Dropbox" sudo chflags -R nouchg "/Users/$USER/Dropbox" sudo chown -R "$USER" "/Users/$USER/Dropbox" chmod -R u+rw "/Users/$USER/Dropbox"
Will be asked for your password (sudo).
Hope this helps. :wink:
Thanks again for all your help.
You haven't posted results of both commands, but only the second command's result! Actual state (file's basic attributes) could be seen from the first command's result. So can you post the result of:
ls -ld "/Users/drmarkcart/Dropbox/My Mac (Mark-Carters-Macbook-Retina-3.local)/Desktop/Incompatible Software/qmasterd"
Result is:
-r-xr-xr-x 1 drmarkcart staff 294992 29 Oct 2008 /Users/drmarkcart/Dropbox/My Mac (Mark-Carters-Macbook-Retina-3.local)/Desktop/Incompatible Software/qmasterd
Could be useful to be known also the containing folder' attributes, i.e. result of:
ls -ld "/Users/drmarkcart/Dropbox/My Mac (Mark-Carters-Macbook-Retina-3.local)/Desktop/Incompatible Software"
Result is:
drwxrwxr-x@ 3 drmarkcart staff 96 26 Mar 2019 /Users/drmarkcart/Dropbox/My Mac (Mark-Carters-Macbook-Retina-3.local)/Desktop/Incompatible Software
...
I have tried to delete the qmasterd file that resides in the Incompatible Software folder on my desktop. It can't be deleted via putting it in the trash (file in use error).
Some info could comes up with mentioned commands' results above. If the "file in use error" is getting up, check whether you have opened the file in some way (either with handling program or loaded indirectly somehow).
I don't know what qmasterd does so am not sure what program might be using it. I assume it was relocated in the Incompatible Software folder during a system upgrade at some point?

What you mean "Fix" here? 🧐 Is it the turning off of backup... and everything back when you turned it on, or something else? I can't figure out of your description, is the problem gets back while you have turned off the backup feature or after that (i.e. is everything stable in that time or not). Can you clarify (repeat the "exercise", if needed)?
Sorry if I was not clear. The problem does not occur when I turn the backup off. That is, when backup is turned off, I don't have to type my password twice on startup or restart. Turning it back on means the problem returns.
I thought removing OneDrive had fixed the problem with backup turned back on but this was not the case. I am still getting two requests for my password on each reboot.

Dropbox application asks for your password causa don't have access to "qmasterd" file and tries fix this itself (that's why permissions are needed). The file is accessible for read and execution only (-r-xr-xr-x), but not for write (something the application expects for all files in Dropbox folder).
You mentioned the initial 2 commands (at the very beginning) got process without errors. But there are still some special attributes set to the containing folder ( drwxrwxr-x@ ). 🤔 Can you confirm that both commands pass successfully, without errors? I'm suspicious because seems the immutable flag is still on the folder (the folder is locked), which is something really strange after successful commands completion (their purpose is to clear such flag - to unlocks the folder). See what can be seen in the Finder's Info window for this folder. Try unlock it in some other way. Let see what are those flags exactly. Post the result of following little bit modified command:
ls -ld@ "/Users/drmarkcart/Dropbox/My Mac (Mark-Carters-Macbook-Retina-3.local)/Desktop/Incompatible Software"
Everything else seems normal.
Try also following:
sudo chmod -RN /Users/drmarkcart/Dropbox

🙂 That's great! Whatever the reason is, it's related to localized subfolder, not to entire Dropbox folder content. 😉
PS: One thing you can try as a workaround, if there is nothing you want to sync in "Incompatible Software" folder, is move this folder outside your Desktop. Put it on some place outside of any sync scope.

That worked - I am no longer receiving requests for my password on startup or reboot. Thanks for your persistence.
I also did a search on problems deleting qmasterd:
It looks like it can only be deleted when the system is not running so I will try deleting it from the recovery drive.

Hi mcarter,
Yes, 😉 Now you will not be asked for you password continuously!

Seems, the folder isn't SIP protected. We haven't checked this protection for the file. Could be assumed it is. Such a protection is active only on system device/partition/volume. If you can move the folder on other (non system) place. you could do whatever you want (including deletion of containing files). Other way, if you can't move folder out of your system partition, could be turning the SIP protection off temporary. And of course, if you boot up from a recovery drive, the place where 'qmasterd' is in will not be on system place in that time (in the same time system place is different and/or SIP is turn off). Do whatever is most convenient for you. 😉
Good luck.
Thanks again for your help (and persistence).
