Restarting your Mac can refresh system resources and potentially fix unresponsive applications that may be affecting the Touch Bar’s performance. To perform a simple restart, follow these steps:
Confirm that you want to restart your Mac when prompted.
Before restarting, make sure to save any open documents or work to prevent data loss. This action is particularly effective if an application becomes unresponsive or freezes, impacting the Touch Bar’s functionality.
After the restart, check if the Command + S function has been restored. If the issue persists, you may need to explore further troubleshooting steps or consider resetting the System Management Controller (SMC) as outlined in the next section.
Resetting the System Management Controller (SMC)
If your MacBook Pro continues to experience issues with Command + S not working, resetting the System Management Controller (SMC) may resolve the problem. The SMC is responsible for managing behaviors related to power, battery, and thermal management, among others. Resetting the SMC is a straightforward process but varies slightly depending on the type of chip your MacBook Pro has.

Shut down your Mac.
Wait for at least 30 seconds.
Turn on your Mac.
After resetting the SMC, check if the Command + S functionality has been restored. This process can also fix other power-related issues such as charging irregularities, unexpected shutdowns, or fan noise problems.

To ensure that the Touch Bar on your MacBook Pro is configured correctly, follow these steps:
Click the Apple logo () → System Settings.
Scroll down to the Keyboard option.
Now click Touch Bar Settings under Keyboard navigation.
Make sure the following parameters are enabled for your device. If they are already enabled, try toggling them off and then back on again. Once you have made the changes, click ‘Done’.
After adjusting the Touch Bar settings, it’s crucial to test the functionality. Press and hold the Fn (Function) key to see if F1 to F12 appear on your Touch Bar as expected.
If the Touch Bar still does not respond correctly, consider other troubleshooting methods such as refreshing the Touch Bar or consulting Apple Support.
Adjusting Touch Bar Preferences
To ensure the Touch Bar on your MacBook Pro operates correctly, it’s essential to verify and adjust its settings. Start by accessing the Touch Bar settings in the System Preferences. Here’s a quick guide to help you through the process:
Click the Apple logo () → System Settings.
Scroll down and select the Keyboard option.
Click on Touch Bar Settings under Keyboard navigation.
Once you’re in the Touch Bar settings, you’ll find several options that you can customize to your liking. For instance, you can decide what the Touch Bar displays—App Controls, Expanded Control Strip, or a combination of both. If you’re experiencing issues, try toggling the settings off and then on again, which can often resolve minor glitches.
After making changes, ensure to hit Done to save your preferences. This step is crucial as it confirms the adjustments you’ve made.
Remember, if the Touch Bar is still unresponsive after adjusting the preferences, you may need to explore further troubleshooting steps, such as refreshing the Touch Bar or checking for software updates.
Reboot in Recovery Mode
Initiating Recovery Mode
Entering Recovery Mode on your MacBook Pro is a critical step when troubleshooting Command + S issues. To initiate this process, shut down your Mac completely. Then, press the Power button or Touch ID button and immediately press and hold Command + Option + R or Command + Shift + Option + R until the Apple logo appears. This sequence will boot your Mac into Recovery Mode, presenting you with various utilities to diagnose and fix problems.
Once in Recovery Mode, you can perform several actions to address system issues:
Use Disk Utility to scan, verify, and repair drives
Restore from a Time Machine backup
Reinstall macOS
It’s important to note that if the Recovery Mode doesn’t appear after following these steps, you may need to restart your Mac and attempt the process again. Exiting Recovery Mode is straightforward; simply select “Restart” from the Apple menu or choose your normal boot disk from the Startup Disk option if your Mac keeps booting into Recovery Mode.
Navigating macOS Recovery Options
Once you’ve initiated Recovery Mode on your MacBook Pro, you’ll be presented with several utilities to help troubleshoot and fix issues. Navigating through these options is crucial to resolving the Command + S not working problem.

Restore From Time Machine Backup: If you have a backup, you can restore your Mac to a previous state.
Reinstall macOS: Download and reinstall the factory version of macOS, which can help with software-related issues.
Get Help Online: Access Safari to look for solutions or contact support.
To exit Recovery Mode, simply select ‘Restart’ from the Apple menu. If your Mac keeps booting into Recovery Mode, use the ‘Startup Disk’ option to choose the normal boot disk and restart.
Remember, if you’re using a Mac with Apple silicon, you may need to select a user and enter their administrator password after clicking the gears icon (Options) and hitting Continue. Follow the on-screen instructions carefully.
Reboot in Safe Mode

Entering Safe Mode
Booting your MacBook Pro into Safe Mode can be a crucial step in diagnosing and resolving issues. Safe Mode performs a check of your startup disk and attempts to repair directory issues, which can often resolve problems related to system stability and performance.
For Intel-based Macs, the process involves:
Shutting down your Mac and waiting for 10 seconds.
Restarting your Mac and pressing the Shift key until the login window appears.
For Macs with Apple silicon, you should:
Shut down your Mac and wait for 10 seconds.
Press and hold the power button until the startup options window is displayed.
Select your startup disk, press the Shift key, and click ‘Continue in Safe Mode’.
Once in Safe Mode, you may notice reduced functionality, but this environment allows you to run essential tasks without the interference of certain software conflicts.
Remember, if System Settings works in Safe Mode but not in normal mode, it’s likely that a peripheral or software is causing the issue. Disconnect non-essential devices and try restarting normally.
Diagnosing Issues in Safe Mode
Once you’ve entered Safe Mode on your MacBook Pro, it’s time to diagnose the issues that might be causing the Command + S shortcut to malfunction. First, check if System Settings operates correctly in Safe Mode. If it does, attempt a normal restart and access System Settings again. Should the problem persist, consider the peripherals connected to your Mac. Disconnect all except for the keyboard and mouse, and restart.
In some cases, unused applications, extensions, or login items could be the culprits. Uninstall any that you no longer need. This can help free up RAM and potentially resolve the issue. Remember, Safe Mode limits your Mac to essential functions, which can aid in identifying problematic software.
If after these steps the Command + S shortcut is still not working, it may be necessary to assess the security settings. Sometimes, issues with these settings can prevent certain functions from operating correctly.
Use Touch Bar in Safe Mode
Testing Touch Bar Functionality
After rebooting your MacBook Pro in Safe Mode, it’s crucial to test the Touch Bar’s responsiveness. This will help you determine if the issue is related to software conflicts or if it persists even without third-party applications running in the background.
Begin by opening native apps like Finder or Messages to check if the Touch Bar responds to different commands.
Next, try adjusting system settings using the Touch Bar, such as volume or brightness, to ensure it’s fully functional.
If the Touch Bar operates correctly in Safe Mode, it suggests that software conflicts may be the root cause of the problem. In this case, you can proceed to identify and resolve these conflicts upon a normal system restart. Remember to back up any important files before attempting this fix and proceed with caution.
Identifying Software Conflicts
When the Command + S function fails to work on your MacBook Pro, software conflicts could be the culprit. To identify these conflicts, follow a systematic approach:
Exit Safe Mode and perform a normal restart of your Mac.
Navigate to the installed applications menu and scrutinize each third-party software.

For essential applications, ensure they are updated to their latest versions.
Running a comprehensive malware scan is also crucial, as viruses or malicious software can disrupt hardware performance.
Remember, keeping your macOS updated is vital for maintaining system stability and resolving potential software conflicts.
Reboot in Single User Mode
Accessing Single User Mode
Single User Mode on a MacBook Pro is a special boot option that gives you access to a Unix shell for advanced troubleshooting. To access Single User Mode, follow these steps:
Release the keys when you see the Apple logo or a spinning globe.
Once in Single User Mode, you will be presented with a command-line interface where you can run various diagnostic and repair commands. It’s a powerful tool for experienced users to resolve complex issues.
Remember, Single User Mode is primarily for those with a good understanding of macOS and Unix commands. If you’re not comfortable using the command line, it’s best to seek professional help or explore other troubleshooting methods.
Performing System Diagnostics
When faced with persistent issues on your MacBook Pro, such as the Command + S shortcut not working, performing system diagnostics is a crucial step. Apple Diagnostics is a built-in tool that can help identify hardware-related problems. Before initiating the diagnostics, ensure that all external devices are disconnected, except for essentials like the keyboard, mouse, display, and Ethernet connection. Also, make sure your system is updated to the latest version and then shut down your Mac.
To start Apple Diagnostics, turn on your Mac and immediately press and hold the D key until you see a screen asking you to choose your language. After selecting your language, the diagnostic will begin automatically.
If Apple Diagnostics finds issues, it will display an error message along with follow-up steps. Pay close attention to these instructions as they may involve contacting Apple Support or visiting an Apple Store. Remember, this tool is particularly useful for detecting problems that are not immediately apparent through regular troubleshooting methods.
Use Apple Diagnostics to Test Your Mac
Running Apple Diagnostics
To troubleshoot hardware issues on your MacBook Pro, Apple Diagnostics is a reliable tool. Before initiating the diagnostics, ensure that all external devices are disconnected, except for essentials like keyboard, mouse, display, and Ethernet connection. Here’s how to run the diagnostics:
Release the key when the diagnostic interface appears.
If Apple Diagnostics identifies any problems, it will display an error message with corresponding reference codes. These codes are crucial for understanding the nature of the issue.
It is essential to address any error codes by consulting Apple’s official support or an authorized service provider.
Should Apple Diagnostics fail to resolve the issue, consider reaching out to Apple Support or visiting an authorized service center for further assistance.
Interpreting Diagnostic Results
After running Apple Diagnostics, interpreting the results is crucial for identifying the next steps to fix your MacBook Pro. Error codes will guide you on the specific issues your Mac might be facing. It’s important to cross-reference these codes with the official Apple support documentation for detailed explanations and recommended solutions.

Refresh the Touch Bar
Force Quitting Problematic Apps
When the Command + S shortcut fails to work on your MacBook Pro, it could be due to an application that has become unresponsive or is interfering with system processes. Force quitting these problematic apps may restore functionality to your Touch Bar, including the Command + S operation.
To force quit an application:
Select the application you suspect is causing the issue.
Click ‘Force Quit’ to terminate the app.
Remember, force quitting an app may result in the loss of unsaved data within that app. Proceed with caution and save your work frequently.
If you’re unsure which app might be the culprit, consider closing apps one by one, starting with those that are not essential for your current tasks. If the issue persists after all apps have been closed, further troubleshooting may be necessary.
Clearing Touch Bar Cache
Clearing the cache can often resolve persistent issues with the Touch Bar. To do this, follow these steps:
Open the Finder app and select ‘Go’ from the menu bar, then ‘Go to Folder’.
Enter ~/Library/Preferences/ and find the file named apple.touchbar.agent.plist. Move this file to the Trash.
Navigate to ~/Library/Caches/ using the same method. Here, delete all files within the cache folder, but do not delete the folder itself as this could cause further issues.
After clearing the cache, it’s a good idea to perform a restart of your MacBook Pro to ensure that the changes take effect and the system refreshes its cache.
Remember, handling system files can be risky; ensure you know what you’re deleting. If unsure, consider seeking professional assistance or contacting Apple Support.
Conclusion: Reviving Your MacBook Pro’s Command + S Functionality
In summary, addressing the issue of Command + S not working on your MacBook Pro involves a series of troubleshooting steps that can restore its functionality. From checking modifier key assignments and force quitting apps to restarting your Mac and refreshing the Touch Bar, each method plays a crucial role in resolving potential glitches. If these initial steps fail, more advanced solutions such as resetting the SMC, booting in Safe Mode, and using Apple Diagnostics can be employed. Remember to back up your data before attempting any fixes and proceed with caution.
