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 your MacOS is…
To check to see if there is an update to macOS you need to follow these steps:
If you are running Mojave:
- Open System Preferences.
- Click on Software Update.
- Your Mac will check for updates before comfirming if your Mac is, or isn’t, up to date. If you need to run an update do so as this may fix any issues you are experiencing.
If you are running High Sierra or older:
- Click on the Apple logo in the right corner of your Mac screen.
- Choose Software Update.
It’s the same on an iOS device. The update to Safari will come as part of the operating system update.
To check if iOS needs to be updated:
- Tap on Settings.
- Software Update.
Note that sometimes it’s a software update that causes the issues you are experiencing.
For example, back in January 2016, many iOS and Mac users found that their Safari browser would crash every time they tried to tap the URL bar or open a new tab. The Safari app would close, forcing them to launch it again, only for the issue to reoccur.
The problem was reportedly caused by Apple’s Safari Suggestions, the feature that offers up automatically completed URLs as you type in the URL bar.
By the end of January 2016 Apple had apparently fixed the problem with an update, but it seems that for a few months that year Safari continued to be plagued by the issue on and off.
