password field automatically filling with little dots, and other problems ever since installing El Capitan

Since I posted on the 16th Dec and received the response from JimmyCMPIT and followed his advice the fault has recurred on one further occasion when coming out of sleep mode. Believing it to be a keyboard issue I picked it up (in rather angry mode!!) turned it over and gave it a couple of firm but gentle taps on my desk! This stopped the ghostly inputting of password letters and I was able to clear the field and input password correctly.

Given the latest posts on this subject, it would seem to me now that my most recent experience must have been just coincidence and my 'desk tapping technique' really played no part! So far, however, there has been no recurrence of the fault.

This is an interesting but infuriating fault, and I am looking forward to a definitive answer to the problem on these pages.

Tend to agree the keyboard tapping is a red herring. My Mac now does it every time it goes to sleep and I am also seeing an increasing number of disconnects between the Mac and he keyboard and mouse which tends to make me think there is an issue with either the Bluetooth software or hardware. As well as the password field, if I leave the Mac so it does not require a password after going into sleep mode then all typing after waking from sleep either is spurious characters or more normally seriously delaywe (character on screen appears 5 -10 seconds after key press per letter)

Am currently trying to see if not allowing the Mac ever to go into sleep mode prevents the problem as I am getting fed up having to reboot it every time it wakes

Deeply frustrating and making the Mac almost unusable

I Also have this problem. it started with Mavericks and still exists with El Capitan. Only happens on my iMac and not on the MacBook Pro.

Hi everyone.

I have the same problem with my Bluetooth keyboard and tried hard to solve it. I have a late 2013 iMac running El Capitan, but the problem was there with the previous version of the system.

I have had my keyboard replaced by an Apple Store and this didn't solve the problem. So nothing to do with a faulty nor dirty keyboard. Of course, the batteries were replaced by fresh ones. An old wired keyboard, as well as an old first generation Bluetooth keyboard have been used without any problem. I also have a mouse and a trackpad connected through Bluetooth, without problem.

I have opened a case with Apple service which I contacted on the phone 4 or 5 times, and been told ultimately to bring the iMac back to the Apple Store. I was instructed to do a fresh reinstall of the system, which I did when back home. To no avail. Got back for a third time at the Apple Store where the tech said I'd probably be better wait for an update in the OS that would correct the situation.

Out of nowhere, I thought the problem could be from waking up the iMac using the keyboard, so for months now I always use the mouse to wake it up. And this seems to have cleared the problem. I have noticed that if I tap the spacebar to wake up the IMac, this will almost always provoke the syndrome of spurious characters sent to the Bluetooth buffer.

But then, there are instances where the problem rises up, even though I think (not 100% sure) I've waken the system using the mouse. I still have the case number at Apple, so I will give them another call and see if there are any new info in their database concerning this annoying problem. Keep you informed if anything interesting shows up.

I too have had this Apple Wireless Keyboard/ Bluetooth/ Wake from sleep issue on my late 2014 27" 5K Retina iMac. This issue also affects entering items in the Safari search field. The one thing that always works for me is to turn the keyboard OFF then back ON again to regain keyboard control. It only works until the next wake from sleep however. I agree that using the Apple Magic Mouse or Magic Trackpad to wake iMac from sleep, seems to avoid the problem. The issue almost always seems to happen when using the Apple Wireless Keyboard to wake from sleep. I am running OS X 10.11.4 Beta 5 (15E56a) currently, but this issue began for me with the first version of OS X 10.11 and still persists. I have reported this to the Apple Beta Software Program/ Feedback Assistant probably twenty times since the first version of OS X 10.11. They seem to be aware of it, as they contacted me through Feedback Assistant a couple of days ago.

This issue only affects my 2014 iMac. I have a mid 2011 27" iMac that has not been affected by this issue. They have different Bluetooth Firmware versions. Hopefully this will get resolved at some point.

If you start looking through the forums, you will find quite a few people have this problem. They title it differently so it can be a little hard to find. We are definitely not alone in this issue.

I am having the same problem

I have had this problem for awhile. I find that if I remember to turn off safari and then hit sleep or shut down it does not happen. It feels like someone is trying to get into my computer and is trying all kinds of things during the night. I know this sounds paranoid, but why does it only happen to me if I forget to turn off safari. I had signed up with a Geeks company back in October of 2014. I keep thinking it might be them.

I always start up if on sleep by using my remote mouse and that does not make any difference. Safari left on is what makes the difference for me.

Do others have this problem with safari is on at night?

The problem is the Mac is filling in the password field on the login screen (like it is typing by itself), not autofill in safari. This is not relating to the problem being discussed.
