Help removing ghost guest login

So I have no Guest user enabled:

However, when I turn on the computer, there's a Guest login on the login screen. I need to get rid of that Guest login as it's not a valid login .. no Guest login is enabled.

I've tried the disable Find my Mac .. that didn't work.

Is it possible to change back prior to the Guest login showing up by using via Time Machine?

The login screen has an actual Guest login. I've enabled the Guest user shown in the picture above and then actually

have 2 Guest users shown at login.

Looking in Finder, I have myself as the admin, then the named users who have rights and a shared folder.

That said, as I've been searching for an answer, even with the Guest profile enabled, Finder doesn't show Guest in this list.

I have no idea what was going on.

The iCloud wasn't selected on either device.

I always turn off the Mac when I'm not using it.

All of this happened this morning:

Did a sync .. iCal was still only syncing from the Mac to the iPhone, not vice versa.

I had previously read an old post about someone power cycling their iPhone and that took care of the problem.

So I did one power cycle and one reset on the iPhone.

Did another sync and then .. the iPhone was syncing to the Mac but not vice versa .. ?!?

So simply randomly trying something, I went to Info and rather than syncing All Calendars, I selected only the Home calendar which is where I had placed a test calendar entry on both devices .. I also unselected the don't sync events older than ____ days which I had at 4000 days (ensuring the last 10 years are sync'd .. just a number I selected years ago).

I tried the sync .. it sync'd both directions. ?!?, but in a good way.

I took it back to all calendars, deleted one device's test entry on the other device, sync'd .. it was gone on both .. tried the other direction .. gone on both. Now everything is working properly.

I realize these are just better versions of a PC and we know PCs have LOTS of glitches, but it still just makes me shake my head sometimes .. to think, we run our lives with these things.

Anyway, if nothing else, your input helps bring up other ideas. So again, thank you for your help. Have a good weekend.

Let me try another idea .. every user login must have 'user.whatever' information buried deep in the hidden workings that allows the login to work. Where is that information kept and what are the file names?

Hi Eric

I hindsight I'm fairly sure this was either directly related to a website that downloaded demo to my computer OR due to my trying to delete the related files. It was supposed to have an uninstall for the demo but didn't .. so I manually deleted what I thought was related and that's when everything started to glitch.

So I tried your Safe Mode idea. The ghost Guest login was still there at startup in Safe Mode. So I restarted the computer, went to look at something in Security and Privacy and saw that my Firewall was turned off and was grayed out when I logged in to turn it back on. So I rebooted the computer, and was able to turn the Firewall on the second time. But at that point I figured there were too many issues so I punted. I restored the computer from the day before everything went squirrelly. It's working properly now. No issues, the firewall is on and there's no ghost Guest login.

I guess the moral of the story is be careful what you delete.

Thank you for your help.

Hi Eric

So my mac was restored and was working properly .. until I went to sync my iPhone to the Mac.

The computer's calendar does sync properly to the iPhone, but the iPhone calendar won't sync to the computer.

I'm NOT using the iCloud .. I use a wired sync to my computer so I have a 100% backup of the phone.

All the calendars on both devices are turned on. When I tested the sync in both directions, I used the Home calendar .. the test from the Mac to the iPhone worked but the same Home calendar test from the iPhone to the Mac didn't work.

Thus far, I've turned the iPhone iCloud off and back on. I've gone to Library/Calendars and deleted the calendar cache files (4 total). I deleted two pending events from Library/Calendars/Pending Events. I clicked iTunes sync to replace the calendar on the iPhone when doing one of my many sync's I've tried. I reset my Trusted computers in the iPhone and sync'd again.

I haven't tried reauthorizing the computer (not sure that would do anything). I haven't tried one I read about that has you go to Terminal and delete the sync history (the directions didn't state what happens when you do that).

There are several posts talking about this exact sync issue, but they aren't current and don't help.

So, what do I need to do to get my iPhone calendar to sync to my Mac calendar?

Again, thank you for your help.
