I can't enter passwords in Safari 11.1 on macOS 10.13 High Sierra because the last character gets removed I installed a brand new 10.13 a few days ago. I downloaded it from the App Store and I installed all updates. I'm runnning Safari Version 11.1 (13605.1.33.1.4).

Somehow I managed to log into Google, but I can't log into any other website. Safari does the following when entering text into password fields  – on every other webpage except for Google:


the first character is entered
after that, it looks like the last character is removed after keyup
this happens when using the internal or an external keyboard


Normal fields like text, textarea etc. work fine, though.

Here's a gif showing the problem – no Backspace or Shift+Del is pressed. This happens just in Safari  – Chrome and Firefox work fine:





I have the following settings:


autofill: don't store passwords and credit card information
no extensions are installed
Adobe Acrobat plug-in is installed


I tried to change the settings and to disable the Arcobat plug-in, but nothing changed.



It seems that macOS’ autocorrection kicks in. I noticed this behavior in a password-field that could be switched to plaintext: Characters get replaced with emojis. For example:

()

I assumed you checked your accessibility and keyboard preferences. I have had numerous issues with keyboard setting being modified/added during the updates. sticky keys and other settings were modified that I wasn't aware of...I had to start using the manual keyboard viewer until I was able to get it fixed...

.

only other thingi I can think of is trying on an alternate or guest login to see if you have the same problem on a clean user.

I know I am still struggling with my fare share of HSierra simple glitches but I hope you can get this one solved! Good luck!
