Easy Fixes For Common Safari Problems on Mac

If you own a high performance car that can only drive in the slow lane, you might as well have bought a bicycle. The same rings true if your Mac and high speed internet connection is hobbled by poor performance from Safari. Your experience on the information superhighway is dependent on the reliability of your browser of choice.

If you find that Safari crashes or is slow, we’re going to show you how to eliminate these problems and get back in the fast lane.

Put the va va voom back in your web browsing today!

Fix Safari crashes

How to fix Safari crashing and other common browser problems

Surfing (the net) is great until you fall. When Safari starts crashing, it’s clear that something is broken. Let’s do something about those common Safari crashes.

Clear browser cache to speed up slow Safari

Temporary data or browser cache is designed to make your web experience a faster one but it can, under some circumstances, hamstring your browser speed to a glacial crawl.

Browser cache can become corrupted, and apart from privacy issues (more on that later) it can cause Safari to crash altogether. If you get a Safari crash, it’s important to take note of when and how it crashes. Does Safari crash on launch or does it crash when you visit a specific site?

If you have a problem with one particular site, this is easy to fix. All you need to do is remove the site history of that site from Safari.

  • Go to the Privacy section of Safari’s preferences
  • Click the Details button that appears under the "Remove All Website Data" button
  • Find the site and remove it from the list

If you are experiencing problems on a variety of sites, then you should try to clear all Safari browser cache.

To manually clear Safari cache files:

  1. Navigate to Preferences in Safari
  2. Click the Advanced tab
  3. Enable Show Develop menu
  4. Click on Develop in menu bar
  5. Select Empty caches

How to cleanup Safari cache files manually

If you have any concerns about doing this safely, use CleanMyMac 3 System Junk module - a Mac cleaning utility that will reliably clear your Safari in just three clicks:

  1. Open CleanMyMac
  2. Select System Junk tab
  3. Click Scan and click Clean

Easy peasy lemon squeezy.

Disable search suggestions in Sarafi to improve browsing speed

Search suggestions in Safari can be a great help to speed up the process of finding what we want. But a common crash related to this feature was found to be stopping the search and Safari in its tracks. The Safari search bar crash, as it is known, has been addressed for some in updates.

If you still believe the problem is affecting you, simply disabling Search Suggestions should do the trick:

  • Go to Safari > Preferences
  • Click on the Search tab
  • Under "Search Engine Selection," uncheck the "Include search engine suggestions" box
  • Close Preferences

How to disable Search Suggestions in Safari on Mac

When Safari stops responding - force shutdown and restart

When Safari is operating optimally, you’ll hardly ever have to watch Indiana Jones and the Endlessly Rotating Multicolor Wheel of Doom.

However, when Safari is not responding, sometimes you just need to let it take a moment. It could be that a web page is loading a heavy script or your Mac’s resources are currently focused on another task.

  • Resist the urge to Force Quit Safari
  • Count to 20
  • If there is still no response, see if you can be patient for just one minute longer

Safari Running too Slow? Tips to Speed it Up

How to fix Safari slowness and freezing on your Mac

Is Safari still not responding? Patience won’t solve everything. Without regular maintenance, your browsing experience can gradually slow down. Poor maintenance and bad habits can even push your Mac’s resources to the point where slowness becomes a regular part of your browsing experience. If that sounds familiar, it’s time to fix Safari.

Extremely slow internet browsing? Stop to keep multiply tabs open

One of the easiest fixes is to close Safari tabs that you don’t need to use. That’s just common sense, right? It is, but we all know at least one person who seems to be on a mission to set a world record for having the most tabs and windows open. The trick is not to be that person.

Each window and tab compete for resources on your system, so closing what you don’t need is the easiest way to improve Safari performance.

But what if you want to read a site or page later, but you don’t want to bookmark the site? No problem – just add it to your reading list. This will store content that you would want to read offline later.

  • In Safari and other apps, click the Share menu and choose Add to Reading List. You can also right-click on a link and choose Add Link to Reading List, or hover over the address bar and click the plus "+" icon.

How to add site to reading list

To access your reading list:

  • Navigate to Safari’s sidebar, then click the "reading glasses" icon.

Disable DNS Prefetching

The point of all of this is to make sure that Safari’s performance isn’t bogged down by having too many open tabs. If you are someone who efficiently manages their tabs yet Safari still crashes, lags or freezes, you should disable DNS prefetching.

DNS Prefetching is a feature designed to make surfing the web faster by scanning over embedded web page links and querying your DNS server to resolve each link to its actual IP address. Ironically, a feature that is designed to make your browsing experience faster can actually weigh down performance.

If Safari lands on a web page with hundreds, and sometimes thousands of links to resolve, the process could freeze Safari.

If you suspect this could be the issue, disable DNS prefetching using this method:

  • Open Terminal
  • Enter the command defaults write com.apple.safariWebKitDNSPrefetchingEnabled –boolean false
  • Press enter

How to disable DNS prefetching

If you revisit the site that had been giving Safari problems and the performance is improved, then the solution worked. However, if there is no noticeable performance boost, it would be a good idea to enable DNS Prefetching and rather troubleshoot other areas.

To re-enable DNS Prefetching:

  • Open Terminal
  • Type defaults write com.apple.safariWebKitDNSPrefetchingEnabled
  • Press enter, quit Terminal and restart Safari

What about privacy in Safari?

How to protect your privacy in Safari browser

Data collection on the internet is a scary thing. We’re going to show you how to use Safari privately and securely. From clearing of browser history to the removal of cache and cookies and a whole lot more, follow these easy methods.

Remove cookies and autofill forms

Cookies by themselves are not actively intrusive on your privacy; however, they store data in ways that can be used for user profiling and website tracking among other things. While cookies make the browsing experience faster, and the web experience more dynamic, some users may have privacy concerns.

Similarly, autofill forms can be quite scary. When you’re typing in a field or form on your browser and Safari reveals suggestions that you really wish it didn’t know, it’s time to clear away the autofill data.

To manually remove cookies in Safari browser:

  • Navigate to Safari > Preferences > Privacy > Manage Website Data
  • Now you can remove cookies for specific sites or simply Remove All

Remove cookies manually in Safari browser

To manually clean up autofill entries in Safari browser:

  • Navigate to Safari > Preferences > Autofill
  • Deselect each option and restart your browser

Cleanup autofill forms in Safari manually

To clean away all of your Safari tracks, from cookies to browsing history and even autofill, you can turn to CleanMyMac 3. Once launched, simply click on the Privacy tab and select Safari. Now you can easily choose what browsing data to delete from your system, all from one convenient window.

Keeping your privacy intact is as easy as that.

Private Browsing in Safari

If you’d like to stay off the grid, Jason Bourne, Safari’s Private Browsing option is what you should be using.

When you use a Private Browsing window:

  • Each tab in the window is isolated, so websites you view in one tab can’t track what you do in other tabs.
  • Safari doesn’t remember the web pages you visit or your AutoFill information.
  • Your recent searches aren’t included in the results list when you use the Smart Search field.
  • Safari doesn’t remember changes to your cookies or other website data.
  • Plug-ins that support Private Browsing stop storing cookies and other tracking information.

To use Private Browsing with Safari simply choose File > New Private Window. To make Safari open private browsing by default go to Safari > Preferences, click General, click the "Safari opens with" pop-up menu, then choose "A new private window."

Bored of Bing? Change your Safari's default search engine

Did you know there are other search engines besides Bing and Google? With Safari you have four choices for your default search engine - Google, Yahoo, Bing, and DuckDuckGo.

If you’re interested in privacy, we recommend using DuckDuckGo, which doesn’t track or store your personal information.

Whether you want greater search privacy or just to try something new, change your default search engine by following these easy steps:

  • Go to Safari > Preferences > Search
  • Select your search engine of choice

How to manage extensions and plugins in Safari

Cleanup extensions and plugins

Browser add-ons don’t always add up to good experiences. We’ll show you how to shed them to speed up Safari and eliminate a common cause of Safari issues.

Remove Safari Extensions (Add-Ons) and Plugins

If Safari is still giving you 99 problems (but efficiency ain’t one), misbehaving extensions (also called add-ons) and plugins can cause Safari to be slow, or crash altogether. Safari extensions are developed to enhance your browsing experience, but they can sometimes have the opposite effect. In a worst case scenario, they can even contain nasty malware.

To get a sense of the problem, trying launching Safari in safe mode (launch while holding shift). This will load Safari without any extensions and plugins. Does your experience improve? Then you’ve probably get a troublesome extension.

To remove Safari extensions manually:

  • Choose Safari > Preferences in the top menu
  • Open Extensions tab
  • Remove the extensions you don’t want

Manage extensions and plugins

Note - The best practice is to turn them all off and then turn each one on, one at a time, to see if you can identify the culprit.

For a clearer view and more control over your Safari extensions, install and launch CleanMyMac 3 and follow these steps:

  • Click on the Extensions tab
  • Click on the Internet Plugins tab or the Safari Extensions tab
  • Easily toggle items on and off or remove them for good

Manage Safari extensions and plugins in few clicks

Disable or uninstall Flash or other browser plugin

Flash is a browser plugin, but because it is often the cause of problems, we decided that it deserves its own section. Flash is pretty but high maintenance and it chows your browser and system resources. That’s why Flash is almost consigned to the dustbin of tech.

Is Safari not responding? Did Safari crash? Flash is the first suspect that you should remove.

To remove Flash manually:

  • Download the uninstaller from Adobe.
  • Choose your OS
  • Launch the uninstaller from your Downloads folder on your Mac
  • When the uninstaller runs, click Uninstall
  • Enter your admin password and close your browser

To remove Flash in few seconds:

  • Launch CleanMyMac 3
  • Click on Extensions
  • Click on Preference Panes
  • Select "Flash Player" and click Remove

Remove Flash from Safari

How to customize Safari

Other safari problems - try to use custom Safari preferences

Hopefully Safari is now working as it should. But you don’t have to stop there. With some hints and tips you can get even more out of your browser by using Safari preferences to customize the experience.

How to see/hide the entire URL in Safari’s address bar

By default, Safari doesn’t reveal full URLs. If you want to see it all, it’s easy to setup Safari to do just that:

  • Go to Safari > Preferences > Advanced
  • Toggle "Show full website address"

What to do when Safari push notifications aren’t working

When you get a notification of something you wanted to know, it feels great. When you get a notification that you didn’t want to know, it feels annoying. To mute some of the more annoying sites simply turn them off in Safari > Preferences > Notifications.

Add Safari as default browser

A Safari to remember

With these fixes to common Safari problems on Mac, your Safari experience should be drastically improved. When Safari is performing at its best, it makes for a great browser experience. We hope you feel empowered enough to know that next time Safari has an issue, you can solve it yourself. Or use a helpful app like CleanMyMac to save the day.

If all else fails, you could always just use CleanMyMac’s Uninstaller to reset Safari and start from scratch.

Not so much "saving the day" as "starting a new day."
