MacBook Air is unable to pair with my Apple devices after macOS Sequoia 15.6.1 update

After the Sequoia 15.6.1 update my MacBook Air has been unable to pair with my other Apple devices (watch, iPhone). I get the message "PAIRING UNSUCCESSFUL. ....MacBook Air is not supported." Is this a common issue? How can I restore Out of the blue my MacBook Air is unable to pair with my watch and iPhone.

You don’t Pair an iWatch to a computer


You must Pair the iWatch to an iPhone 


Set up and pair your Apple Watch with iPhone


You don’t Pair an iPhone to the computer like one may do for a Bluetooth Keyboard or Mouse


You can use Handoff 


Hand off tasks between your iPhone and your other devices


You can also use Continuity 


Use Continuity to work across Apple devices

I am a novice when it comes to the "Computer World". Since the MacBook Air 15.6.1 update and the 18.6.2 update to my model 12 iPhone, the MacBook Air and iPhone, Calendars are not sharing events added on either as used to be the norm. My (uneducated) guess is that the said updates have impacted in the interface I am so used to.

Am I on the right track, is there something I can do to fix the annoying problem that has cropped up in the last couple of days?

Predicated on, both devices are signed into the same Apple ID ( formerly Account )


Both devices are also signed in the Apple iCloud Account 


The Calendar Apps , in iCloud, is turned ON on Both Devices 


Apps using iCloud


Further, Keep your calendars up to date and share them with iCloud


Events added to Calendar on one device should Sync across to the Other deviceand visa versa 


Now, if the devices are using some Third Party Cloud Based service ?


All bets are off and it would be better for the User ( you ) to investigate this issue with them 


In my setup, this has been working across 3 Apple Computers each with Sequoia 15.6.1, 1 iPhone 15 Pro with iOS 18.3.2 and an iWatch Series 9 with iOS 11.6.1
