Question: Q: tccd process using over 1Gb RAM
I am recently having problems with getting out of free memory. I inspected processes in Activity Monitor and found that a tccd process is using over 1Gb (once almost 1.5Gb) RAM.
- What is the process responsible for?
- Is it normal to use such high amount of memory?
- How can I fix that?
MacBook Pro (13-inch, Mid 2012), OS X Mountain Lion (10.8.2), 4Gb RAM

When you googled ‘tccd process Mac’ what did you get?

Well, nothing useful.

Back up all data.
Triple-click the line below to select it:
Right-click or control -click the highlighted line and select
from the contextual menu. A Finder window should open with a file selected. Move the selected file to the Desktop, leaving the window open. Log out, log back in, and test. If there’s no change, put the file you moved back where it was, overwriting the one that may have been created in its place. Then log out again. Otherwise, delete the file you moved.

I had a similar problem in which tccd was consuming a lot of CPU and memory. The underlying problem turned out to be related to broken rules in Hazel. I documented it here:

I had the same problem. The tccd process took more and more of the memory.
The culprit however was a launchagent I had created. This launchagent watched a folder and was always kept alive.
The launchagents task was to run a shell script and was being called all the time.
I have no more tccd problem since I have changed this launchagent.
So if you have this problem, I advise to have a critical look at the launchagents or launchdaemons (
/Library/LaunchAgents/, /Library/LaunchAgents/ or /Library/LaunchDaemons/).

Just drag that icon to the Trash. It’s in the wrong place.
There are no viruses that affect macOS.

Tried doing it. It doesnt delete. Just purchased my mac 2 days ago. May I know what is this?
Aug 29, 2020 6:12 PM
The folder is located in library/applicationsupport

Well, you originally wrote that it was in the Applications folder. Leave it alone.
Stop thinking about viruses. There are none. Just. Stop.
Aug 29, 2020 8:15 PM
Some articles on web says it»s malware. Should I worry? Bought my mac 3 days ago. ,
Aug 30, 2020 12:52 AM
If you purchased the MacBook Air recently, there is no possible way that it has a virus, especially in the Applications folder. Even after owning a MacBook for years (saying this from personal experience) it is almost impossible to get a virus on a Mac. Just leave the file alone as doing something to it could damage your computer.
I hope this helps!

If you want proof that TCC is _part of_ the system, here’s a video _by_ Apple that talks about it, from 2016:
TCC stands for «Transparency, Consent, and Control», and you can see Ivan Krstic, the guy who heads Security Engineering and Architecture at Apple, talking about it in this video at Apple’s World Wide Developer Conference (WWDC) in 2016.
There have been exploits that attacked TCC, since it is one of the system components that «controls» what things an app can do, but you don’t want to remove or break the actual system component.

Try to remove it with the free version of Malwarebytes.
Aug 31, 2020 1:25 PM
I already tried scanning it using Malwarebytes. Nothing was found. Other ways to remove it?

Can you manually drag it to the trash?
Aug 31, 2020 3:52 PM
No. Nothing happened when I drag it. Also tried deleting it in safe mode. It does not delete also.
Aug 31, 2020 4:03 PM
You can try the free version of Avast and run a full scan of your drive (can take an hour or so)
I know a lot of people don’t like Avast but it’s good at finding hidden-away malware and remove it. You could always remove it after it’s done it’s job. Personally I leave it installed on my Mac; just my choice.

There should be no /Library/Applications folder.
/Library/Application Support/com.apple.TCC is normal. Leave it alone.
Do not do anything, install anything, or use anything in a misguided effort to delete it.
Sep 1, 2020 10:54 AM
/Library/Application Support/com.apple.TCC is normal. Leave it alone.
Are you sure? com.apple.TCC is reported all over the place as being malware / unwanted.

Went to nearest power mac. Staff told me it is part of new os. Also saw the folder in their display unit.

Not just Google!
..but if Apple say it’s OK, I’m happy to trust them 🙂

Havent experience any pop ups, redirections etc. Also looked the launcher agents and daemons folder and did not see any malicious files.

It is not new. It has been part of macOS for a very long time.

Yeah. TCC stands for «Transparency, Consent, and Control», and you can see Ivan Krstic, the guy who heads Security Engineering and Architecture at Apple, talking about it in this video at Apple’s World Wide Developer Conference (WWDC) in 2016.
So, it’s been around for at least that long, and is part of the system. There have been exploits that attacked TCC, since it is one of the system components that «controls» what things an app can do, but you don’t want to remove or break the actual system component.

Question: Q: The folder “com.apple.TCC” can’t be opened because you don’t have permission to see its contents.
I’ve noticed a folder with a ‘no access’ sign on it’s bottom right corner — com.apple.TCC — and when i try to open it it says «The folder “com.apple.TCC” can’t be opened because you don’t have permission to see its contents.»
Does anyone know what this is and why i can’t access it? No-one else uses this macbook but me.
Also, as of this afternoon , I can’t two finger scroll on any web browser?

Hi there StevenChell,
I had this folder too. same location as yours.
I simply Right Clicked on the folder.
—> saw that I didn’t have permission
—>unlocked the padlock(Using my Administrative rights’ pw)
—>Clicked the ‘+’ sign @ the bottom
—>Added myself to the list and gave myself read only permissions.
Then I could view it. Not sure if Linc’s method (Wow — a piece of art that post!🙂) is necessary if all you want to do is know what the file is used for and what’s inside of the folder.
Like Topher says — it’s a System Folder — nice to know what it does though, so thanks Topher for that 🙂

Back up all data .
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you’ve set special values for those attributes on any of your files, they will be reverted . In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn’t cause the problem. If none of this is meaningful to you, you don’t need to worry about it.
I’ve tested these instructions only with the Safari web browser. If you use another browser, they may not work as described.
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer , then reboot. You can demote the problem account back to standard status when this step has been completed.

In what folder are you encountering this directory?
This folder is created and managed by the privacy framework which manages which programs can access details like your contacts, location, and other similar personal information. It usually resides in the Macintosh HD > Library > Application Support directory, and was likely moved from this directory to wherever you are encountering it; however, what may have moved it may be a mystery.
The folder should be recreated by the «tccd» process as you use the system’s various privacy access services, so if it was moved from its original location then a new one should be there, which should be the functional one for the «tccd» process.
As for the scrolling, try going to the Accessibility system preferences, then to the Mouse & Trackpad section, and click the Trackpad Options. button. In here ensure the «Scrolling» box is checked (toggle it off and on, for good measure), and perhaps adjust the scrolling speed as well. This should spur the system to re-write the settings that govern these behaviors for the trackpad, and hopefully kick it back working again (if not immediately, then try rebooting to see if this helps).

Thanks a lot. So long as it;s nothing to worry about I’ll just leave it as it for now. then.

Scrolling still isn;t working, that was the first thing i tried. Strange for it just to ‘turn off’
Dec 14, 2013 5:06 AM
It is something to worry about. Some of your files have wrong permissions.
Dec 14, 2013 6:49 AM
Does it work in other user accounts (create one in the Users & Groups system preferences pane, and then log into it to test)?
Dec 14, 2013 9:11 AM
No, it’s blocked on a guest account too. Scrolling seems to be working fine now. One problem solved.
Dec 15, 2013 12:40 PM
Access to the com.apple.TCC folder will likely continue to be blocked. This is a system folder that was somehow moved or created in a location that you frequently access. It would be odd for this folder to be located in your account somewhere (ie, in your Desktop or Documents folder), but may have been moved there by a third-party utility or program you might have used. Where specifically are you seeing this «com.apple.TCC» folder on your computer? It would help to know the parent folder tree that it resides in (e.g., Macintosh HD > Users > «username» > Desktop, if you see it on your desktop).
Overall this is likely not a major problem at all, and one that can be ignored unless it continues to crop up, either with this same folder or similarly with others. The folder simply has permissions settings that restrict access to the hidden system accounts that created it. Being separate from your user account, these will have access but yours does not, hence the no-entry symbol and inability to open it.
This could have happened in one of two ways: Either the folder was created in the location you have found it, or it was copied or moved there from a hidden system location (which may be done by a third-party maintenance tool, for example) but done so with permissions settings preserved. Either way, unless you are finding it in the Macintosh HD > Library > Application Support folder, then it is not being used by relevant system services that usually create this folder, so you can move it to the trash (you will need to authenticate to do this), and then delete it. The system services that use this folder will have already created a new one in the appropriate location.
