Just got a new Mac Air - it's my first apple computer after mostly leveraging windows laptops from work.

I set up Lastpass by downloading Lastpass for Safari extension in the App Store, and followed instructions so it allowed autofill in setting.

However, instead of autofilling username and password on a site, a dialogue box opens up on the top left that prompts me to start typing.

Not sure what it wants me to type, but even typing the username I know I use for the site I am trying to get autofill to work on doesn't trigger autofill. I had entered my username and password manually the first time, but the next time I went to the site it wasn't autopopulating. I tried closing down the browser and restarted it, closed down my mac and restarted, even trashed the extension and redownloaded it again. None of this caused the autofill feature to just work.

It looks like I am signed into Lastpass correctly - the redbox with dots appears both in the username/password fields, as well as in the toolbar. It simply isn't autopopulating and nothing I do with this weird dialogue box prompting me to "start typing" gets me to the experience of having my vault simply autopopulating the info.

Anyone come across this and can suggest a fix?

Super frustrating, making me wonder why I switched to Mac in the first place - I thought the OS and interfaces was "just supposed to work"!

In Safari I can login to LastPass and it works fine. Then a little while later it goes grey and says "Login" but when I click on that it opens the LastPass app and it's logged in already. I cannot fill passwords or get logged into the extension . It works fine in Chrome on the same Mac but Chrome uses a lot more battery so I want to stay with Safari.
