Issues with spacebar preview may arise from conflicts with various software on your MacBook. For example, when you press the spacebar, an issue arises where a blue box appears around the selected item, but instead of opening for preview, it doesn't respond as expected.
Even worse, if you double-click the selection to preview, there is a delay, and a program opens to view your selection rather than providing a preview. In this post, we'll look at six ways to fix the Spacebar Preview not working on Mac error. Keep reading!

The QuickLookUIService is the underlying process for Quick Look, visible in the Activity Monitor. Quitting the QuickLookUIService can be beneficial in resolving issues with Quick Look not functioning correctly on macOS versions like Big Sur, Monterey, Ventura, Sonoma, and others.
To accomplish this:
Step 1. Open "Activity Monitor" from the "Applications > Utilities" folder.
Step 2. Search for "quicklookuiservice", and click the close icon to terminate the service.

If you encounter the issue of MacBook Quick Look not working, especially when attempting to use the spacebar for file preview, it might be due to the file not being stored locally on your Mac.
Quick Look can only preview files that have been previously opened on your Mac. In the case of using cloud services like iCloud, it's essential to download files by clicking on the download icon before utilizing Quick Look for a preview.
For users employing cloud backup services such as Dropbox, which features a "Smart Sync" option to keep files online, ensuring instant downloads upon clicking to open, there's a solution.
By adjusting the Smart Sync setting to "Local" or "Available offline," users can easily download files for convenient previewing.
This can be done by:
Step 1. Access "Finder" and locate the "Dropbox" folder.
Step 2. After that, right-click on the desired folder or file and select "Make available offline".
At times, the spacebar preview feature operates seamlessly within Finder but may not respond when attempting to view files in a specific application.
This issue often stems from the application's settings, where the spacebar might be assigned to alternative actions.
To verify this, you can open the app in question and inspect the keyboard shortcuts, typically listed under options like "Open Viewer" or "Manage Viewer" in the top-left menu bar.
For example, the Quick Look functionality on Mac may not work as expected in Mojave when previewing files in the Photos app.
This is because Apple modified the preview shortcut from the spacebar to the Return key in this particular update.
However, it's worth noting that Apple recognized this adjustment as a mistake and rectified it in subsequent updates, restoring the ability to use the spacebar for file previews in the Photos app on Monterey.
In conclusion, resolving the issue of Spacebar Preview not working on your Mac involves a variety of troubleshooting methods.
From checking Open Viewer Settings to rebooting in Safe Mode, these steps are designed to address different potential causes of the problem.
If you're still facing issues after trying these solutions, considering professional assistance or exploring relevant user communities can provide valuable insights.
Always ensure you have backups before making significant changes to your system. By following these comprehensive steps, you can enhance the functionality of Spacebar Preview on your Mac and enjoy seamless file previews.
