Being the default browser shipped with every Mac, you are very likely using Safari as your main way of accessing the Web. Therefore, if something goes wrong where Safari either loads and runs slowly, crashes on startup, or is otherwise not functioning correctly, then you might find yourself in a bit of a frustrating situation. If you need to reset aspects of Safari in order to regain functionality, then even though the options for doing so are somewhat scattered, you can still use them to regain use of your browser.
Remove site history
Safari has its built-in tools for clearing temporary data that may be causing problems. To do this, go to the Safari menu and choose the option to Clear History and Website Data. If the problem you are experiencing only happened in the last hour or the past day, then you can try choosing the option here for encompassing that timeframe, otherwise you can remove all history data in this menu.

- Go to the Privacy section of Safari’s preferences.
- Click the Details button that appears under the “Remove All Website Data” button.
- Search for your site, and then remove only it from the list.
Clear Safari’s Web caches
Apple has somewhat hidden the options for clearing Safari’s caches (temporary local storage for a number of different settings and configurations), but they are still available:
- Go to the Advanced section of Safari’s preferences
- Click the Show Develop menu in menu bar option
- Select Empty Caches from this menu
Disable Extensions

Extensions give additional functions to Safari, but may also cause some problems if they contain bugs. Therefore, try going to the Extensions section of Safari’s preferences and sliding the setting to “Off.” Alternatively, you can try disabling plugins on an individual basis (each should have a checkbox for enabling/disabling), but first turning them off globally and then testing Safari will help indicate whether these are contributing to the problem. Also be sure you use the Updates button in these preferences to check for and install any new versions of your extensions.
Disable and manage plugins
Plugins handle specific internet content that sites may try to display for you, but also may cause problems when loading these sites. Therefore, as with Safari Extensions, you can try disabling them to see if this clears problems you are experiencing:
- Go to the Safari’s Security preferences
- Uncheck the Allow Plug-Ins checkbox
- Reload your Web pages, or optionally quit and re-launch Safari
In addition to disabling them in this way, you can manage plug-ins on a per-site basis by clicking the Website Settings button and then adjusting which sites are allowed, denied, or must ask for loading a specific plug-in.
Manual approaches
The above approaches should be most of what you need to clear and reset problems in Safari; however, if not then you can take more surgical approaches to clearing out Safari’s configuration data and getting the browser up and running again. Keep in mind that this approach will fully reset Safari and clear out your history, local bookmarks, and other settings, so be sure you make a backup of your system before doing this. Then quit Safari, and perform the following steps:
Remove Safari’s configuration folder:
- Open the Go menu in the OS X Finder
- Hold the Option key and choose the Library option that appears
- Move the “Safari” folder in here to your desktop
Remove Safari’s window state:
- Open the Library > Saved Application State folder
- Locate the “com.apple.Safari.savedState” folder
- Move this folder to the trash
Remove Safari’s application caches:
- Open the Library > Caches folder
- Locate all folders that begin with “com.apple.Safari”
- Move these folders to the trash.
Remove Safari Cookies configurations:
Mac Library Internet Plug Ins
- Open the Library > Cookies folder
- Remove the file called “com.apple.Safari.SafeBrowsing.binarycookies”
Remove Safari’s preferences:
- Open the Library > Preferences folder
- Remove any file that begins with “com.apple.Safari”
Remove user plug-ins:
- Go to the Library > Internet Plug-Ins folder
- Move all items from this folder to your Desktop (or elsewhere)
Remove global plug-ins:
- Go to the Macintosh HD > Library > Internet plug-ins folder
- Move all items out of this folder except the following plug-ins:
These ones may also be removed for testing your situation, but should be replaced. In addition, if removing plugins does not show any difference in your browser’s behavior, then replace them. However, you can also replace them by downloading the latest versions from their developers’ Web sites.

It looks like this issue is related to Safari 12's discontinued support for NPAPI plug-ins. Safari 12 release notes says:
Mac Hd Library Internet Plug Ins Adobepdfviewer Plugin
Likewise, MS Silverlight plug-in is not working anymore and according to my understanding it plays some role in using Sharepoint sites on Safari.
This issue is really critical to me as I can't anymore edit documents in SharePoint sites at my work! I'm also bit doubtful that Microsoft would release any fix to this shortly...

Couple of questions:Mac Hd Library Internet Plug Ins Silverlight Plugin
- Does anyone have any more insight about this issue?
- The Sharepoint plug-in was working fine in the previous version of Safari (11.1.2). Is there any way to downgrade Safari back to previous version? Unfortunately I don't have Time Machine or any other backups of the operating system.
- Any other ideas how to solve or circumvent this issue?
Any comments would be highly appreciated!
