Messages are not syncing between my mac and iphone

Messages are not syncing between my mac and iphone after ios 11 and high sierra updates. Mac is only showing old messages before the update. Other handoff features are working properly. Any suggestions?

iPhone 7, iOS 11.2.1

Hello and welcome to Apple Support Communities, denimallel.
If I understand your post correctly, since updating you iPhone messages are not syncing with your Mac even though other Continuity features are working normally. Being able to use messages from all your devices certainly makes keeping in touch easier. I'm happy to help.
Go ahead and set up your iPhone and Mac for messaging again using these steps:

If you have an iPhone, the text messages that you send and receive on your iPhone can appear on your Mac, iPad, and iPod touch as well. You can then continue the conversation from whichever device is closest to you.

Set up SMS and MMS messaging

Use this feature with any Mac, iPhone, iPad, or iPod touch that meets the Continuity system requirements. Make sure that your devices are set up as follows:

  • Each device is signed in to iCloud with the same Apple ID.
  • On iPhone, go to Settings > Messages > Send & Receive. Make sure that the Apple ID at the top of the screen is the same Apple ID that you're using for iMessage on your other devices. Add a check to your phone number and email address, so that you can be reached by iMessage at both. Do the same on your iPad or iPod touch.
  • On iPhone, go to Settings > Messages > Text Message Forwarding, then choose which devices to allow to send and receive text messages from this iPhone. If you're using two-factor authentication for your Apple ID, a verification code appears on each of your other devices: enter that code on your iPhone.
  • On Mac, open Messages, then choose Messages > Preferences. Click Accounts, then select your iMessage account. Make sure that the Apple ID shown here is the same Apple ID that you're using on your other devices. Add a check to your phone number and email address.

Use SMS and MMS messaging

To use this feature, just start conversations as normal in the Messages app on any of your devices. You can also start a conversation by clicking a phone number in Safari, Contacts, Calendar, or other apps that detect phone numbers. All of your incoming and outgoing messages appear on all of your devices.
