Is there any way of typing a text message on a proper keyboard (like I'm now doing on my Mac) and then EASILY transferrring it to my phone so I can send it via text? (No, email isn't really an option).
My elderly Mac mini is running High Sierra and has it, haven't tried it on there as it's used as a media server under the TV. In applications simply called Messages.
Fitzer. Same Mac here (2014 Mac mini). Found Messages, seems to be linked to Facetime (not used). It didn't want to register a new number for some reason! But the principle seems sound, so, like with Tora's Chrome thingy, I'll persevere and see where I get.
