Stop Apple's Safari web browser from crashing on your Mac, iPhone and iPad with our guide to fixing common Safari problems and avoiding issues with web pages. Does Safari keep crashing on your Mac, iPhone and iPad? Is Safari running so slowly on your Mac that you can't use it properly? Is Safari just closing on your iPad without warning? In this feature we're going to look at what to do when Apple's Safari web browser isn't working properly.
There are a few reasons why Safari might be crashing:
There might be something going on in the background of the website you are visiting one you have opening another tab. You might be running an older version of the software with an issue that has since been fixed.
A webpage might be using a plug-in, an extension or other software that has a problem. The first thing to check is how many tabs you have open in Safari. Including any sites you might have 'Pinned' in Safari on your Mac. If you are anything like us, you open new tabs in Safari (Command on the Mac, or + on iOS) without closing the one you have stopped using (after all you might need to return to it). Should content of one of these tabs continue to run in the background, then it might be causing an issue.
Each tab or Safari window takes up a little space in memory. Have too many tabs open and Safari starts fighting for resources with other apps, and it ends up running far more slowly than it should. This is more likely to be a problem on the Mac than the iPad or iPhone, but it's still worth following the advice below on an iOS device.
How to close multiple tabs in Safari on the Mac:
Hold down the Option/Alt key and click on File. Choose: Close Other Tab (if you don't press Option/Alt you will only see Close This Tab. Every page other than the one you are looking at will be closed. Close multiple Safari windows on the Mac. If you tend to open many windows while you are using Safari.
- Click on File
- Close All Windows
How to close multiple tabs in Safari on iPad/iPhone:
Multiple tabs open on your iPhone or iPad? While this shouldn't cause issues in the same way it might on the Mac, because the tabs you aren't using will be suspended (they can still be active on a Mac, playing video for example), you may still benefit from closing them all down (least of all because it gets very difficult to find the tab you opened yesterday if you still have tabs open from this time.
To close all your Tabs by tap and hold on the tab icon in the bottom right. A sheet will open with the options: Close All [Number] Tabs, Close This Tab, New Private Tab, and New Tab.
- Tap on Close All [Number] Tabs.
- Check what's responsible
- You could also look to Activity Monitor to see if a particular site is being singled out for taking up a lot of resources.
- Open Activity Monitor.
- Click on Memory.
- Sort by Memory to see what is using up the most of your RAM.
- You can select that site in Activity Monitor and then click on the X to close that process.
- The benefit of this method is that you can close the page that is causing the problem and keep other pages open.
Apple regularly updates Safari to address security concerns, so it may be that you are experiencing problems that have been corrected by an update (or problems caused by a software update). You could start by checking what version of Safari you are running.
- In the Safari menu on your Mac, click on Safari.
- Click About Safari.
- A box will pop up that states the version of Safari you are running.
However, your Mac should update Safari automatically whenever Apple releases an update to Safari, because Safari comes as part of macOS. So your version of Safari should be up-to-date as long as you’re MacOS.
Clear website data and cache:
When you visit a web page in Safari it stores a copy of it in a cache. This copy enables it to load the web page faster next time you visit.
How to clear Safari cache on a Mac
- You can start by getting rid of all your website data, including your web browsing history. Click Safari in the menu at the top of the screen.
- Choose Clear History. In older versions of Safari this listed and Website Data as well, but in new versions Website Data is automatically cleared as well (unless you press Option/Alt in which case you see the option to keep Website history).
- This will actually clear data on all your devices that are logged on to the same iCloud account, so you’re Mac, iPad and iPhone can be done at the same time. Choose from the last hour, today, today and yesterday, and all history.
- Make your choice (we recommend All History) and click on Clear History.
