How to fix Mac file sharing issues on Big Sur
There are a couple of workarounds available to Mac users on the Big Sur software.
1. Delete unnecessary data
Having too much data on your MacBook can slow it down. Between downloads, apps, and other programs, your Mac can get clogged up before you know it. Many apps come with junk files that you mightn’t notice, and this extra can remain behind after you delete the app. All of this could affect the file sharing process on a Mac. Ensure you delete any files you don’t need and free up some much-needed space.
2. Allow guest users to connect to shared folders
Ensure that guest users are able to access shared files on your Mac by going to System Preferences > Users & Groups > Guest User. Click on the padlock icon in the bottom-left corner and enter your credentials. Finally, check the box next to Allow guest users to connect to shared folders.

Shared folder not showing up
If you’ve enabled file sharing on your Mac, but the folder isn’t visible in Finder, follow the steps below to make it appear.
- Open Finder, then click on Finder in the menu at the top of the screen, followed by Preferences
- Click the Sidebar tab
- Check that Bonjour computers and Connected servers are selected. If not, check both boxes.
File sharing permissions not working
Most likely, the reason you wouldn’t be able to access shared files on Mac is that the user didn’t grant you access to those files.
That user is responsible for setting permissions for shared files, like Read Only, Write Only, or Read & Write. But those permissions don’t automatically apply to all new files you add to that folder.
Follow the steps below to fix error file sharing permissions issues on Mac.
- Open System Preferences
- Double-click on the Sharing folder
- Ensure the File Sharing box is checked (this means file sharing is enabled). Then, click on that option and select a shared folder and user on the right of the window
- Now click on the arrows next to the relevant user and set the permissions.
File sharing password not working
Make sure you check with the user if the password for a shared folder is still the same—maybe they changed it and forgot to let you know.
