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

Have you restarted your Mac, if so does the same behaviour exist.

Using apps to clean, optimise, verify and repair your Mac are not necessary, Onyx is fairly benign but CleanMyMac has the reputation of one of the worst offenders often removing important system files and causing numerous problems. It is highly recommended to uninstall this, refer to the developers instructions to uninstall this app fully.

The Mac looks after itself pretty well so throwing apps at it to alleviate any perceived problem can often escalate the issue.

Another thing you could try is to boot up in Safe Mode and see if you can add apps to your Security & Privacy preferences. Use safe mode to isolate issues with your Mac - Apple Support

I would at this point just re install Mojave. And this time don't install any anti-virus apps or anything that cleans, optimises or promises you the world, Macs don't need such things and they sometimes create more problems than they claim to resolve. There are no viruses for Macs, and the OS tends to look after itself pretty well, if you want to keep on top of adware/ malware install Malwarebytes, there is a free version.

FWIW ... I have the same issue. I attempted a fresh reinstall (wiped hard disk, reinstalled Mojave from scratch) and the issue remained. No antivirus software present to blame and no other applications are installed yet.

To verify, I reinstalled High Sierra. The issue doesn't happen in High Sierra.

Finally, I installed Mojave again (with a blank disk again) and the issue returns. This is a Mojave issue.

> 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.

No it's not. I experienced exact issue when I installed ESET - security features disappeared, after I uninstalled ESET security features came back once again. Unfortunately now when I check/uncheck access to any app, my system freezes and I can't click anything until restart, after restart I am able to check/uncheck apps in security but after a while when I try it again system freezes again.

I have upgraded my machine to Mojave...and after upgrading I cannot check/tick any application or add any applications to accessibility-->Privacy.

But Later I noticed that...There is one lock button bottom which is not letting us to make any changes. If we click on that then the screen will be unlocked and we can manage the applications in accessibility

I don't have ESET, so that's not the issue in my case.

After restarting, no change - still had an empty Accessibility app list.

Decided to uninstall Logitech Options. Upon attempting to empty the trash to complete the uninstall, VMware Fusion complained with a popup about needing Accessibility for full functionality (it was one of the apps originally listed in the Accessibility app list).

.

Went ahead and emptied the trash, figuring I was probably going to have to go back to Sierra and reinstall everything anyway, deep quit all my apps, and restarted. Voila, the Accessibility app list was fully restored. Will reinstall Logitech Options now.

Sure hope this isn't going to be a recurring issue. I can't believe how buggy Mojave is. This is just one of many issues I've encountered. Our IT department doesn't let us upgrade from Sierra to Mojave, but my new MacBook came with Mojave installed, so they just left it. Thinking about installing Sierra. Just hate to have to re-install all my apps and VMs, having spent a couple of weeks moving everything over from (hold your noses) an old Windows 7 Pro Dell laptop.

Guess I'll stick with Mojave for now unless the Accessibility issue keeps recurring.

Cheers everyone.

With Apple support on line, we fixed a similar issue using First Aid in Disk Utility in Safe Mode

Never ran into the problem again after upgrading ESET antivirus to v 6.7.400.0

Thanks, reinstalling worked, as stated, it's not just enough to update it.

Maybe it depends on what apps do you add? You can add them one by one and reboot each time to find out which item can affect this.

Also try to enable back System Integrity Protection if you didn't so before.

Just ideas, not sure if it will help.

My list works fine now:

Yes, the new version 6.7.xxx.x resolves the issue. This version was specifically released to address the issue. However, it doesn't resolve (at least it didn't for me) by just updating the software. I had to uninstall and reboot, then download the latest version from ESET directly and re-install. Now everything works fine.

I finally took the MacBook into our IT department. They applied some updates and managed to fix the problem at least for now. My Security & Privacy pane now correctly lists all the apps needing access to the Accessibility functionality. They didn't tell me why they did, but it seems to have involved the /Library/Application/Support/com.apple.TCC/TCC.db file (as it's timestamp changed while in their possession.

So, I made a backup copy of that file to my desktop and plan to replace the one in /Library/Application/Support/com.apple.TCC if I run into this issue again.

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