[FIXED] The Mac File Sharing Not Working

With a file-sharing setup, you can transfer items or folders with other devices on your network. You can even allow other users to access your entire Mac or only certain. In 2017, Apple’s cursory fix to an unprecedented security flaw opened a new can of worms in some macOS High Sierra. The update trigged a bug that disrupts file sharing.

Broken file sharing may also appear if you update to macOS Mojave. Sometimes, malware infiltration, corrupted or omitted system files, incompatible system settings, and digital dirt in your system could be the culprits. So how to fix the issue of Mac file sharing not working. Find it in this post.

Part 1. Apple’s Instruction to Fix Broken File Sharing

"Mac File Sharing permissions not working; Mac file sharing connection failed; Mac SMB not showing files; unable to access shared folder on Mac". If you have encountered one of these problems, try to fix them with the solutions below:

Solution #1 Fix File Sharing with Terminal on High Sierra

A security flaw detected in High Sierra exacerbated vulnerability as anyone could get administrator access on Mac even without a password and username. Apple swung into action immediately to resolve it but inadvertently broke file sharing. Some users discovered that file sharing hits a snag. Apple circulated a step-by-step guide for a quick fix.

1. Launch the Terminal app from the Utilities folder via Applications.
2. Enter sudo /usr/libexec/configureLocalKDCand hold down Return.
3. Type your administrator password and hit Return.
4. Shut down the Terminal app.

At this juncture, file sharing should work again without any problems.

Solution #2 Delete Unnecessary Files

Part 2. How to Deal with Mac File Sharing Not Working

Method 1. Adjust File Sharing Configurations

Once you’ve set up file sharing via System Preferences and Public folder, you transfer items automatically. Alternatively, utilize file sharing options to determine the protocol and other possibilities for each item. If you cannot share files on Mojave, check settings. By enabling File Sharing, you fix the issue.

• From the Apple menu, choose System Preferences > Sharing.
• Next, tap on the Add (+) in the foot of the window to share a specific item. Highlight the folders you want to relocate, then click Add.
• Hold down the Control button, click on the name of the item and choose Advanced Options followed by your preferences. Click on OK.
• You can rope in a few selected users. Choose the item you want to transfer in the Shared Folders list of options, then click the Add(+) and cherry-pick the targeted users. Add users from a network, Mac users, or contacts.
• In addition to identifying users who should access your items, you may also need to restrict the scope of accessibility.

Method 2. Using iCloud

You can utilize other methods to share files from your Mac with other devices. Apple suggests iCloud Drive carves out a straightforward pathway to share files. iCloud Drive auto-saves files in Documents and Desktop directories to the cloud. Apple premised its decision on the presumption that most people save files here.

Follow the steps below to enable iCloud Drive Desktop and Documents access:

1. Launch the Apple menu > System Preferences, then hit iCloud.
2. In the menu, highlight iCloud Drive and select Options.
3. Scroll to the Documents icon and click it.
4. Next, sift through to the new Desktop & Documents Folder listing, and then enable it by ticking the box.
5. There you’ve it. iCloud will now store files to the cloud. Give it enough time if you have mass files or corpus content to move.
