With Messages in iCloud, your entire message history stays up to date across your devices. If you need to free up space in your iCloud storage, you can delete individual messages from all of your devices or turn off the Messages in iCloud feature.
What happens when you delete messages or turn off the Messages in iCloud feature
With Messages in iCloud, when you delete a message, attachment, or conversation on one device, it deletes from all of your devices. This can help free up some space in your iCloud storage, while keeping the rest of your conversations up to date across your devices. Once you delete a message, you can't get it back.
If you don't need to keep your conversations up to date across your devices, you can turn off the Messages in iCloud feature. If you turn off Messages in iCloud on an iPhone or iPad, your message history is included in a separate iCloud backup.
To delete an individual message or attachment, follow these steps:
In a message conversation, touch and hold the message bubble or attachment that you want to delete.
Tap More.
Tap Trash , then tap Delete Message. If you want to delete all messages in the thread tap Delete All, in the upper-left corner. Then tap Delete Conversation.

Learn more about your iCloud storage limit
When you go over your iCloud storage limit, your messages and attachments don't upload to iCloud, and your devices won't back up or download to iCloud. You can still access your most recent messages, but they won't be stored in iCloud and deleted messages will not update on all of your devices. To keep using Messages in iCloud, upgrade your storage or free up space by deleting files that you don't need.
value - The number or reference to a number whose double factorial will be calculated and returned.
Notes
The double factorial is similar to the factorial, except instead of multiplying by each integer value less than or equal to the provided value, it decrements by 2. Thus the double factorial of 8 is 384 and the double factorial of 7 is 105.
If a number or reference to a number with a decimal part is provided to FACTDOUBLE, the decimal part will be silently truncated before calculation.

While you're wearing Apple Watch, your Mac can sense when you're nearby and automatically log you in. You can also use Apple Watch to approve other requests for your administrator password.
Auto Unlock works when you're wearing your unlocked watch and are very close to your Mac. If necessary, move your watch a little closer.
How to automatically log in
This feature gives you instant access to your Mac when you're wearing your Apple Watch. Just wake up your Mac and you're ready to go—without typing a password.
The first time you log in after you turn on, restart, or log out of your Mac, you must log in by entering your password manually. After that, Apple Watch logs in for you.
How to approve other password requests
You can also use your Apple Watch to approve other requests to enter your administrator password. This works anywhere you need to type your Mac password, such as when viewing passwords in Safari preferences, unlocking a locked note, approving an app installation, or unlocking settings in System Preferences.
For example, when you click the lock to make a change in System Preferences, your Mac prompts you to approve with Apple Watch:
To automatically enter your password without having to type it, just double-click the side button on your Apple Watch:
Make sure that your devices are set up as follows:
Your Mac has Wi-Fi and Bluetooth turned on.
Your Mac and Apple Watch are signed in to iCloud with the same Apple ID, and your Apple ID is using two-factor authentication.
Your Apple Watch is using a passcode.
Choose Apple menu > System Preferences, then click Security & Privacy. Select "Use your Apple Watch to unlock apps and your Mac" or "Allow your Apple Watch to unlock your Mac."
If you're not sure whether your Mac supports Auto Unlock, press and hold the Option key while choosing Apple menu > System Information. Select Wi-Fi in the sidebar, then look for "Auto Unlock: Supported" on the right:

If you're having difficulty getting Auto Unlock to work, try these solutions:
In Security & Privacy preferences, deselect "Use your Apple Watch to unlock apps and your Mac," then restart your Mac and turn this setting back on.
If Mail on your Mac keeps asking for your password
Mail might say that it can't connect to your email account, and repeatedly ask you to enter the password for it.
If your Mac is connected to the Internet but suddenly starts asking for your password, you should generally try again later, and if necessary work with your email provider to resolve. If you're using Apple's iCloud Mail, learn how to resolve issues with iCloud Mail.
Why is Mail asking for your password?
Mail asks for your password when it is connecting to your email provider, but can't connect to your email account because your email provider isn't accepting your email password.
Your email provider may reject your password for several reasons, including:
You're not using your current email password. If you updated the password on another device, make sure that you're using the same password on your Mac.
Your email provider needs you to update or reset your password for security reasons. For example, if you're using Google's two-step verification, your Gmail account in Mail requires the appropriate app-specific password.
Your email provider deactivated or suspended your account. Contact your email provider for help.
Check your password in Internet Accounts preferences
Depending on the type of email account you're using, you might be able to correct the password as follows:
Choose Apple menu > System Preferences, then click Internet Accounts.
Select your mail account in the sidebar.
If you see a password field for your account, delete the password and type the correct password.
Close System Preferences, then open Mail and try using your account again.
If Mail still asks for your password, the password is probably incorrect. Your email provider can help you verify your email settings and make sure that you're using the correct password.
Test using webmail
Many email providers offer webmail, which is a way to use email with a web browser such as Safari, instead of with an email app such as Mail. For example, if you're using an iCloud Mail account, you can use iCloud.com to send and receive email.
Because the password that you use with Mail is usually the same password that you use with webmail, try signing in to webmail with that password. If it doesn't work there either, your password is probably incorrect. Your email provider can help you verify your email settings and make sure that you're using the correct password for the Mail app.
If you forgot or want to change the email password for a different email service, contact the email provider or request a password reset from their website.
