In today’s digital landscape, effective communication tools are essential for seamless collaboration. Slack, one of the leading platforms for team communication, offers various features, including screen sharing, which allows users to share their screen during meetings or discussions. However, it can sometimes be frustrating when Slack screen sharing is not working on Mac. In this article, we will explore the common reasons behind this issue and provide you with comprehensive solutions to ensure a smooth screen sharing experience.
Understanding Slack Screen Sharing on Mac
Before diving into the troubleshooting steps, it’s important to grasp how screen sharing works on Slack for Mac. Screen sharing enables users to share their desktop, application windows, or documents in real-time, enhancing collaboration and communication. Whether you’re working on a presentation, showcasing a project, or troubleshooting technical issues, screen sharing is a powerful tool.
However, various factors can disrupt this functionality, leading to challenges in collaboration. Understanding these factors will help users address the situation effectively.
Common Causes of Slack Screen Sharing Not Working on Mac
When you encounter issues with screen sharing on Slack, it’s vital to consider the following common causes:
1. Permissions Issues
One of the most frequent reasons for screen sharing failures on Mac is related to permissions settings. macOS requires applications to ask for user permission before accessing the screen or specific applications. If these permissions are not granted to Slack, it will prevent screen sharing from functioning correctly.
2. Software Glitches
Sometimes, software glitches and bugs can impede the normal operation of applications. If you haven’t updated your Slack app or Mac operating system in a while, there could be compatibility issues or errors causing the screen sharing feature to malfunction.
3. Inadequate Internet Connection
A stable internet connection is crucial for effective screen sharing. If your connection is slow or unstable, it may lead to disruptions during screen sharing sessions.
4. Outdated Slack Version
Using an outdated version of Slack can lead to various issues, including screen sharing problems. Regular updates offer critical bug fixes, performance enhancements, and new features.
Essential Troubleshooting Steps
Now that we have an understanding of the causes, let’s delve into the actionable steps to troubleshoot screen sharing issues on Slack for Mac.
Step 1: Check Permissions Settings
To enable Slack to share your screen, you must ensure that it has the necessary permissions. Here’s how to check and update permission settings on your Mac:
Accessing System Preferences

Step 4: Check Your Internet Connection
A reliable internet connection is vital for successful screen sharing. Follow these tips to check your connection:
- Run a speed test to evaluate your internet speed.
- If your connection is unstable, try reconnecting to your network or switching to a different one (if available).
Using a wired connection can also improve stability over Wi-Fi in some cases.
Step 5: Reinstall Slack
If the above steps do not resolve your issue, consider reinstalling the Slack application:

1. Reset Slack preferences
Corrupted preference files can sometimes cause issues. To reset Slack preferences:

- Locate the preferences files (typically named as
preferences.json). - Move these files to a separate location (e.g., your Desktop) for backup.
- Reopen Slack, and it will create new preference files.
2. Check Third-Party Security Software
Some security applications can interfere with screen sharing features. Temporarily disable any active firewalls, antivirus software, or VPNs and test the screen sharing function again in Slack. If it works, consider adjusting the settings of the security software to allow Slack to function correctly.

What are the common issues faced during Slack screen sharing on Mac?
The most common issues encountered during Slack screen sharing on Mac include a blank screen, lagging video, and audio problems. Users may experience a situation where the screen appears blank to the viewers, often due to incorrect screen sharing permissions or settings. Lagging may be attributed to a weak internet connection or high CPU usage, which can diminish the fluidity of the screen shared.
Another frequent issue is audio not being transmitted during screen sharing. This typically occurs when the user hasn’t selected the option to share system audio, or there may be underlying problems with the audio settings on the Mac itself. If you are consistently facing such issues, it’s essential to check both your Slack settings and your Mac’s system preferences to ensure everything is correctly configured.
How can I resolve the blank screen issue when sharing my screen on Slack?
If you encounter a blank screen while sharing via Slack, the first step is to ensure that you have given Slack permission to access your screen. Navigate to your Mac’s System Preferences, then go to Security & Privacy and select the Privacy tab. There, you’ll find “Screen Recording.” Make sure that Slack is checked, which allows the application to share your screen with others.
If Slack is already checked and you’re still facing the issue, try restarting Slack or your Mac. Sometimes, a simple reboot can help refresh the application and rectify any temporary glitches. Additionally, ensure that any other screen sharing applications are completely closed, as they can sometimes interfere with Slack’s functioning.
What steps should I take if my screen sharing is lagging?
To address lagging during screen sharing on Slack, start by checking your internet connection. A stable and strong internet connection is crucial for smooth screen sharing. If your Wi-Fi signal is weak, consider moving closer to the router or using a wired connection for improved stability. Additionally, you can close unnecessary applications and tabs that may be consuming bandwidth or processing power on your computer.
If the issue persists after optimizing your connection and closing background applications, consider lowering the resolution of the content you are sharing. Streaming at a high resolution can strain both your internet connection and your Mac’s processing capabilities. By adjusting these parameters, you should see an improvement in the performance of your screen share.
Can I share audio while screen sharing on Slack? How?
Yes, you can share audio while screen sharing on Slack, but this option must be selected during the setup process. When you initiate screen sharing, you will see a checkbox for “Share computer sound.” To ensure that audio is transmitted along with your visuals, make sure to tick this option before starting the screen share. This is particularly important when sharing videos or presentations that have audio components.
If you forget to select this option or if it appears grayed out, it may indicate that certain permissions are not set. In this instance, revisit your Mac’s privacy settings to grant Slack the necessary audio sharing permissions. Once properly configured, you will be able to share audio seamlessly along with your screen content.
Why is my Slack screen sharing unexpectedly stopping?
Unexpected stoppages during screen sharing in Slack could be due to several factors, including network instability or excessive system resource usage. A fluctuating internet connection can lead to disconnections, causing the screen sharing session to stop abruptly. Therefore, you should monitor your internet performance and switch to a more stable connection if possible.
Another possible reason for this issue may be due to conflicts with other applications running simultaneously on your Mac. If you have too many applications open, particularly those that also utilize system resources or screen sharing capabilities, it may cause Slack to become unresponsive. Closing unnecessary applications or restarting your Mac can help alleviate this problem and allow for a more stable screen sharing experience.
How do I check and adjust Slack permissions on my Mac?
To check and adjust Slack permissions on your Mac, you will need to access the System Preferences menu. Click on the Apple icon in the upper left corner of your screen, then select System Preferences. From there, navigate to the Security & Privacy section. Click on the Privacy tab, which will show you a list of permissions granted to various applications.
In the Privacy section, click on “Screen Recording” and ensure that the checkbox next to Slack is selected. If it is not checked, click the lock in the bottom left corner, enter your password to make changes, and then enable the checkbox for Slack. This adjustment will ensure that Slack has the necessary permissions to share your screen effectively. Don’t forget to relaunch Slack after making any changes to permissions.
