Software Update Catalina

| Posted on by



Update from Catalina or Mojave. Follow the onscreen instructions to finish installing the software update, which should take around half an hour to an hour depending on the spec of your Mac. The update introduced a system-wide dark mode and several new apps lifted from iOS, such as Apple News. It was the first version to require a GPU that supports Metal. Mojave also changed the system software update mechanism from the App Store (where it had been since OS X Mountain Lion) to a new panel in System Preferences. App updates remain. OnyX is a multifunction utility that you can use to verify the structure of the system files, to run miscellaneous maintenance and cleaning tasks, to configure parameters in the Finder, Dock, Safari, and some Apple applications, to delete caches, to remove certain problematic folders and files, to rebuild various databases and indexes, and more.

You can update your iPhone, iPad, or iPod touch to the latest version of iOS or iPadOS wirelessly.* If you can't see the update on your device, you can update manually using your computer.

Before you update

Make a backup of your device using iCloud or your computer.

Update your device wirelessly

If a message says that an update is available, tap Install Now. You can also follow these steps:

  1. Plug your device into power and connect to the Internet with Wi-Fi.
  2. Go to Settings > General, then tap Software Update.
  3. Tap Download and Install. If a message asks to temporarily remove apps because the software needs more space for the update, tap Continue or Cancel. Later, iOS or iPadOS will reinstall apps that it removed. If you tap Cancel, learn what to do next.
  4. To update now, tap Install. Or you can tap Later and choose Install Tonight or Remind Me Later. If you tap Install Tonight, just plug your device into power before you go to sleep. Your device will update automatically overnight.
  5. If asked, enter your passcode. If you don't know your passcode, learn what to do.

If you see an error or need more space when updating wirelessly

If you see an error message while trying to update your device wirelessly, learn what to do. If you need more space for a wireless update, you can update using your computer or delete content manually from your device. Whether you use your computer or update wirelessly, you'll have the same amount of free space on your device after you update.

Some software updates aren't available wirelessly. VPN or proxy connections might prevent your device from contacting the update servers.
