I did not take part in the beta. I said I should have followed it closely, but didn't realize I had to as I never thought something as foolish as this was coming. And if you think your screenshot shows good memory usage, I'm not sure what to say other than for what 1Password does and is, that is not good memory usage.
Worse even, that memory usage will likely grow indefinitely until you reboot. 1Password stays running, so resource management and low memory features are a necessity. When mentioning Electron and it's huge downfalls, I don't think most people are realizing this factor. If you keep the Mac Slack app running for work all day, like so many of us are stuck with, which is an Electron app, just watch its memory footprint and spawned processes throughout the day.
Sorry but there is not an honest answer to fixing their problems at this point. They went down the highway to hell and seem to be "very happy" with their choice. Well their users aren't. If they are going for just Enterprise customers with this move as some have mentioned, it makes a bit of crap-sense but they will lose a big portion of their Mac base. At least, I sure hope they do as this surely deserves a cancellation. One that I'm making within the week after choosing a replacement.
Sad, 1Password has been with me for decades. One stupid choice like this completely destroys all of that history. Of course there's a ton more to explain to people that don't understand what the Electron part of their new app will do or not do for them, but they'll figure it out on their own given some time. I on the other hand, do know and have now used version 8, which is actually worse than I even thought. Not even talking about the sluggish performance. I'm talking about the UI and features. The UI is clunky and as everyone else that's been with the Mac long enough to know what fits and what doesn't.
This new version absolutely does NOT fit in with macOS's - everything.
Everything is just.....off.
This thread has other posts with all of the details that I'm barely scraping the surface of. All of which are downgrades and problems. Once again, enough of my time spent writing about version 8. I am better off spending the next 20 minutes finding a suitable alternative to switch to. They've probably already written off "personal" users anyway from the sound of things. If enterprise is what they want, then whatever. What a waste.
