Speaking of annoying tech problems, LastPass has been thwarting me ever since I received a new MacBook. It was unusable with Safari. LastPass worked fine with Chrome (eats too much battery) and Firefox (leaks too much memory), but no matter how many times I uninstalled and re-installed it, the binary component failed to load.
What is tragic is that the version has not been updated since May 2016, and the problem is a very simple fix, and presumably, a very easy update to the LastPass Installer. Zero help from LastPass tech support, even though we are an Enterprise user. Fortunately, a user figured it out.
The symptoms: In Safari, the LastPass plugin would not display “Copy Password” or “Copy User” and it did not have the icons to do so. Here are some images and fix: http://imgur.com/gallery/40dv9
Once you have it all straightened out, if you go to More Option -> About LastPass, if should show the Binary Component: true (Helper App):
Doesn’t require too much technical skill, but don’t expect help from LastPass.
