This wikiHow teaches you how to update your Safari browser and remove the "This version of Safari is no longer supported" message. If you're using a Mac computer with OS X 10.5 (Leopard) or earlier, you'll need to first purchase a copy of OS X 10.6 (Snow Leopard) and install it on your computer before you can update Safari.
Step
Method 1 of 2: Updating Safari on OS X 10.5 or Older
Step 1. Make sure your Mac computer can run OS X 10.6
You cannot update Safari on OS X 10.5 (Leopard) or earlier so you will need to upgrade your operating system to (at least) OS X 10.6. This means that the computer must also have at least 1 GB of RAM. You can check these requirements by clicking the Apple icon in the upper-left corner of the screen, selecting “ About This Mac ”, and look at the number next to the " Memory " segment.
Step 2. Purchase a copy of Mac OS X 10.6 (Snow Leopard)
You can purchase a hard copy from the Apple Store (https://www.apple.com/shop/product/MC573Z/A/mac-os-x-106-snow-leopard), or use the search keyword " Mac OS X Snow Leopard" on Amazon.
Snow Leopard was the first version of OS X to run Apple's signature App Store. This application is required to update the device to a newer operating system, such as Yosemite or MacOS. You can also use the App Store to update Safari
Step 3. Install OS X 10.6 on the Mac computer
To install it, insert the Snow Leopard CD into the computer's CD slot/drive (on the left side of the computer cover) and follow the on-screen instructions.
You will need to restart the computer during the installation process
Step 4. Click the Apple menu icon
It's an apple icon in the upper-left corner of the screen.
Step 5. Click Software Update
After a while, you should see a window displayed with several update options.
Step 6. Make sure the "Safari" box is checked
You can also choose to update to a newer version of OS X (eg Yosemite) in this window, although the process will take some time.
Step 7. Click Install [quantity] Items
It's in the lower-right corner of the "Update" window. After that, each option marked by a check mark will be installed.
Step 8. Wait for the update to finish installing
You may need to restart the computer in this process. Once done, the Safari for Mac version running is updated to OS X 10.6. You will also no longer see error messages when trying to access pages or software in Safari.
Method 2 of 2: Updating Safari on OS X 10.6 or Later
Step 1. Open the App Store app on the computer
This app is marked by a blue icon with a white “A” on it. This icon is usually displayed in the computer's Dock.
If you don't see the App Store icon, click the magnifying glass icon in the upper-right corner of the screen and type "App Store" into the search field, then click the "App Store" option in the search results
Step 2. Click the Updates tab
This tab is at the far right of the selection bar at the top of the App Store window.
Step 3. Click the Update button which is next to the "Safari" option
After that, Safari will be updated to the latest supported version of the operating system.
Step 4. Make sure automatic updates are enabled
You can make sure that your computer is always running the latest version of Safari by checking that the automatic update feature is turned on:
- Click the Apple menu and select “ System Preferences ”.
- Click the option " App Store ” in the “System Preferences” menu.
- Check the box " Automatically check for updates ".
- Check the boxes to enable automatic system and application updates.
