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

https://appletoolbox.com/2016/07/fix-corrupt-user-accounts-macos/#Reset_Home_Folder_Permissions

I read a bunch of threads and ended up at Reset Home Folder Permissions. I got to step 6 which seems to take a good 10+ mins to run, give or take. After that stopped and before I went to the next step of issuing a command in terminal, I opened the Accessibility pane one more time for good measure and it was WORKING!

I did not do step 7. I hit unlock, and everything was there for me to turn off or on. Since the 2 apps in question didn't work before, I just locked the pane without changing anything since they were already checked. Both apps (Magnet.app and Automator.app) worked without a hitch.

Whew! Let me know @spscmt if that works for you.

On Mojave you might want also try "tccutil reset", for details see "man tccutil"

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 am having this issue on 2 Macs, both on 10.14.3, where the problem started. I just looked at my second mac tonight for the first time after trying to restart "Magnet" app. I got the popup saying Accessibility needed to changed for the app. I went to the Pref pane and could see, like on my first mac, the screen was blank with no entries. Trying to add it did nothing, just like first mac.

So then I'm here on the thread reading this and that and wondering if I'm going to have to get on with Apple support, etc, and see one comment about granting broad permissions to the folder the db file lives in. I went there and saw that it had a red dashed circle, meaning I couldn't change it. I did a quick command-i to get info. Nothing surprising.

But then I went back to the Accessibility entry, which had been blank. Now, all entries were back. Literally the only thing I did on this second mac was 1) visit the folder and try and click into it (red dash circle, 0 bytes in folder) and then 2) try and get info on the folder (command-i), and then the folder was repopulated but greyed out and locked as expected. All the expected apps were in there.

I unlocked Accessibility, granted access to Magnet.app, closed it, and the app works and all looks well.

I will restart this machine, and try the exact same thing on the first mac and see if there is some magical effect of simply trying to click or view the folder:

/Users/<username>/Library/Application Support/com.apple.TCC

If someone else browsing this that still has the problem, can you try my steps 1 and 2?

I've been dealing with this problem too. Nothing seemed to work, commands, removing antivirus, going into safe mode, nothing.

Then I wanted to do a clean install of Mojave, but did a quick recovery install by command-r instead. And as a miracle there they where, the apps in accessibility. My Wacom worked, Teamviewer works!

The only solution I've found is to disable Eset. Looking for an alternative now.

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 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.

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.

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.

ESET acknowledged and fixed this problem with version 6.7.600.0

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.
