Copy Here, Paste There

A: The Universal Clipboard tool allows people to copy text, images and videos on one Apple device and then paste the content into an app on another Apple device. The feature arrived in 2016 with iOS 10 and macOS Sierra, but you need to meet a few other conditions to use it. (Some apps, like Notes, can sync content between iOS and macOS automatically with iCloud.)

You need to be logged into the same iCloud account with the same Apple ID on all of the hardware in the mix. You can check the accounts in the iCloud system preference on the Mac and in the iOS settings on the iPhone; if you have multiple Apple IDs — like an old one used for iTunes Store purchases and another you created to set up a new iPad — you may be logged in under two different accounts.

Universal Clipboard is part of Apple’s Continuity technology, and it generally requires at least iOS 10 on an iPhone 5, and macOS Sierra on Mac computers released in 2012 or later. Both the iOS gadgets and the Mac must have Wi-Fi and Bluetooth enabled, as well as the Handoff feature that allows one Apple device to pick up, using certain apps, where another let off.

To enable Handoff on the iPhone, tap open the Settings icon on the home screen, select General and then Handoff, and tap the button next to Handoff. On the Mac, open the System Preferences icon from the desktop dock, click the General icon and click the box next to “Allow Handoff between this Mac and your iCloud devices.”

When the iPhone and Mac are set up properly, try copying text or an image on one device and pasting it into an app on the other.

— KILLING MESSENGER

A: Facebook Messenger, the company’s chat program, was spun out of the Facebook mobile app in 2011, before the social network removed the chat function from the main app in 2014.

As with other third-party apps, you can remove it from your phone with a few taps. If you use Messenger on a phone running a recent version of Android, open the Settings icon and select Apps & Notifications. Find the Messenger icon; if you do not see it, tap See All Apps (or App Info) first. Tap the Uninstall option.

You can also delete an app from the Android home screen by pressing its icon and then dragging it to the Uninstall symbol that appears at the top of the screen.

You can also remove Android apps by opening the Google Play store icon on your phone, tapping the three-lined menu icon in the top-left corner and selecting My Apps & Games. On the next screen, tap the Installed tab, find the Messenger icon and tap the Open button. When the app’s page is open, tap the Uninstall button.

To delete Messenger on an iPhone, go to the home screen, find the app’s icon and press your finger on it until the tile begins to wiggle.

Once the wiggling starts, a small X appears in the icon’s top-left corner. Tap the X, and when the alert box pops up, confirm you wish to delete the app.

Even if you remove the mobile Messenger app (and do not delete your Facebook account), your Facebook friends can still send you messages when you are logged into the desktop version of the site. A stand-alone web version is also available at Messenger.com. If you prefer not to use the chat function, tell your friends to reach you by other means.
