macOS Mojave - System Preference, Security & Privacy, Accessibility - Not Working/Empty

Read the replies below. None is helpful. It shouldn't be this hard just to change the wallpaper. What happened to the systems preference window in Mojave? Just gone and no satisfactory explanations. Another case of an "upgrade" making life harder and more annoying.

I had the same problem as OP, and re-installing Mojave did not help. Before re-install...the problem spiraled (maybe this original problem, maybe a separate problem with the OS) where every time I restarted, things got a bit worse.

Long story short this fixed it for me! I was able to add Dropbox and Spectacle back to the list.

Also before Mojave re-install -

At one point below my login screen, I had a line that said "AHP_REQ_TO_ENABLE".

After a few restarts: bluetooth became permanently disabled, only one display worked at a time, and I could type but could not see what I was typing in Outlook or Word. None of these things was easy to google at first so I list them for another in the future. In retrospect, many of these seem to do with preference panel preferences being corrupted somehow.

Removing TCC.db also worked for me, thanks!

Some details:

After the deletion the problem persisted until I restarted the computer.

I have ESET Endpoint antivirus and previously granted it with some "control computer" permissions, maybe it's related, maybe not.

I have just deleted mac cleaner and antivirus system

and moved com.apple.systempreferences.plist to the desktop

located in ~/Library/Preferences/com.apple.systempreferences.plist

and everything going smooth

This worked for me, but only temporarily. After deleting the file and rebooting I am then able to add items to the security lists. However, as soon as I reboot again the issue returns and I have to delete the file again and reboot again.

Any other ideas on how to permanently fix this?

Enabling one app at a time also does not work. Every reboot caused the issue to return including if I enabled system protection.

I was able to resolve it though (not in a way I wanted though). Thinking that my A/V might be causing an issue I uninstalled ESET Cyber Security Pro. Even with system protection on, and without re-creating the TCC.db file, as soon as I rebooted after uninstalling ESET everything is working again.

I already tried excluding the /Library/Application Support/com.apple.TCC/*.* directory from ESET scanning and real-time protection, but that did not resolve the issue. Only uninstalling ESET fixed it. Apparently, there must be something in ESET that is causing this issue with Mojave. I have opened a ticket with ESET, but for now I suppose I just can't use an A/V product.

ESET product is something we have in common so most likely it causes the problem.

After I removed TCC.db (and rebooted, perhaps), ESET Endpoint antivirus requested again some kind of control over System Preferences which I temporarily rejected and since then the problem with Accessibility list didn't emerge.

I suggest you to mention a link with your ticket to ESET, this may help others.

Hello, I have exactly same issue, uninstalling ESET caused that now when I add something to Accessibility the list of allowed apps won't disappear BUT now every time when I add some app and restart my MAC after that I add something else to Accessibility the MAC freezes, like I can move cursor but I can't click on anything. It drives me crazy and nothing listed above didn't help.

> Accessibility the MAC freezes, like I can move cursor but I can't click on anything.

Exactly the same problem I had. But I didn't uninstall the ESET and removing TCC.db with temporary disabled integrity protection did help in my case.

How did you delete this? I've tried with sudo and from finder and it won't let me as it's a critical system file

Yes and no. I installed Garmin Express and it stopped working. The security features disappeared. It may be that that created the problem to start with when I updated the apps. I uninstalled the app and the security features came back after a system reboot. I tried with another app and it kept the features without problem.

Is this problem specific to Garmin Express, I'm not sure.

Do you have any 3rd party security software/virus scanner installed?
