Apple’s proprietary chat platform iMessage is available on all of its devices and platforms, even the Apple watch! Apple makes this really secure, useful free service available to everyone who uses its various devices, which also supports regular text messages.
It is not uncommon for iMessage to fail, especially on the Mac. Some of the issues are minor, such as images not loading properly after iMessage idles too long on a sleeping Mac, while other issues are more serious, such as Imessage refusing to operate on the desktop.
It is not a bad idea to examine the problem before assuming the worst. Can you confirm that iMessage isn’t working with everyone or is it just not working when you message one contact?
To find out if it works for anyone, send a few messages to a few different people you know who use iMessage.
If you have trouble sending a message to a single contact with iMessage, the problem probably lies with them. Meanwhile, if iMessage is not working with any of your contacts, and you know they use iMessage, the problem is probably with your device. Using this guide, you can troubleshoot iMessage problems on Macs and fix them.
