Disabling the preview pane in macOS Mojave

Alternatively, you can use the keyboard shortcut "Command + Shift + P" to achieve the same result. This method will ensure that the preview pane remains hidden, even when relaunching the Finder or restarting your Mac.
If you are encountering performance issues due to the Finder generating large icon thumbnails and previews for images and video files, you can also try disabling the icon previews. To do this:
- Open the folder for which you want to turn off column previews.

- Uncheck the "Show preview column" option to disable the preview pane.
- Optionally, check the box for "Always open in column view" to ensure that the settings remain in place.
Note that this method must be applied on a per-folder basis, as there is currently no universal setting to disable the preview pane for all column windows.

Finder generating sluggish performance
If your Finder is generating sluggish performance, there could be several reasons for this, and there are several fixes you can try. Firstly, it is worth noting that Finder can slow down when it is generating previews of large image and video files. A simple solution to this problem is to turn off the image and video preview generation of the Finder, both for icon thumbnails and for the Preview panel that appears in the Column view. This can be done by opening the folder you want to turn column previews off for, then pulling down the "View" menu and selecting "View Options". From here, you can uncheck "Show preview column" to disable the preview pane. This will disable the generation of previews, which can slow down Finder.
Another potential cause of sluggish performance in Finder could be due to low storage space, a corrupted Disk Utility, or a cluttered desktop. To address low storage, you can try freeing up space on your Mac and then reopening Finder to see if it runs faster. If you suspect the issue is due to a corrupted Disk Utility, you can try running First Aid from Disk Utility to fix this. Additionally, you can try to reduce clutter on your desktop by removing unnecessary items.
Third-party applications such as cloud storage or antivirus programs with enabled file synchronization can also cause Finder to slow down. Disabling file synchronization for these third-party applications may help speed up Finder.
If none of these solutions work, you can try force-quitting Finder and restarting your Mac. Additionally, you can try resetting the Finder .plist file, as a corrupted Finder .plist file can cause slow performance. To do this, enter ~/Library/Preferences/com.apple.finder.plist into the search box, select the Finder .plist file, and move it to the Trash. Then, restart your Mac. Alternatively, you can use Terminal to delete the file.
Finally, if all else fails, you can try contacting Apple Support for further assistance.

Finder preview pane reappearing after restart
If you are a Mac user, you may have noticed that the Finder preview pane can slow down your system, especially when you are browsing through folders containing large image and video files. While the preview pane can be useful, it can become frustrating when it reappears after each restart. This issue has been observed by many Mac users, especially after updating to macOS Mojave.
There are several ways to address this issue and prevent the Finder preview pane from reappearing after each restart. One simple method is to hide the preview pane by dragging it to the right edge of the window. However, this is only a temporary solution, as the preview pane tends to reappear upon relaunching Finder or opening a new window.
For a more permanent solution, follow these steps:
- Open Finder in List view.
- Click on "View" in the menu bar.
- Select "Hide Preview Pane" from the menu. Alternatively, you can use the keyboard shortcut "Command + Shift + P" to achieve the same result.
By following these steps, the preview pane will remain hidden even after restarting your Mac. This method has been proven effective for macOS Mojave users.
Additionally, you can explore other options to optimise your system's performance when dealing with large files. For instance, boosting system RAM and upgrading to an SSD drive can significantly enhance the performance of background tasks. Furthermore, if you utilise the Finder Column view, you can disable the Preview panel column for each folder by unchecking "Show preview column" in the "View Options".
