Q: Can't launch  Apple Remote Desktop anymore

Hi All,

 

All the sudden, I can't launch ARD 3.8 (380A95) in El Capitan 11.11.4 anymore.

Every time I try to launch it on one of my Mac, I get a warning telling me that it failed to start "due to an unexpected error" (The Remote Desktop software may not be installed correctly or the computer may require a restart).

It affects all user accounts (so it's not a corrupted user pref) and reinstalling the entire system through the full installer doesn't help.

I can use the Screen Sharing app though…

After reading an old thread with similar problem (Remote desktop administrator software failed to start) I tried deleting all preferences and support files following the instructions on the Apple kb page but it didn't help.

 

I also checked the Console, and it reports:

3/22/16 10:02:46.888 AM Remote Desktop[5905]: OpenConnectionToAgent - unable to connect 2

3/22/16 10:16:36.035 AM ARDAgent[6057]: libcoreservices: _dirhelper: 400: mkdir: path=/var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/C/ modes[2]=0700: Permission denied

3/22/16 10:16:36.035 AM ARDAgent[6057]: confstr on _CS_DARWIN_USER_CACHE_DIR returned an error.

 

Which could indicate a problem with sandboxing, but again, I see warning similar to this one with different apps on different computers without any consequences (I suspect sandboxing makes the logging fairly chatty nowadays). I checked the cache folder it was referring to and didn't notice anything out of place or missing (comparing to another computer where ARD is working).

 

If anyone has a suggestion… I'd be forever grateful

A:

DISCLAIMER: my affected Mac is a crash test machine, I don't care to lose data on it

 

Finally I solved it by trashing the folder "/var/folders/zz/" indicated in console (as described by Cortig).

To delete (empty the trash) the content, you must first deactivate the System Integrity Protection.

 

Good luck,

CU

    Eventually we should only have emptied the /var/folders/zz folder and not removed or renamed. I did the same as you.

     

    Interesting to know that even a Apple's Time Machine didn't work here either.

     

    There is another thread that deals with the same issue because a CCC restore doesn't help here either: https://discussions.apple.com/message/30473108#30473108

    I was getting the same error in Console

    3/22/16 10:16:36.035 AM ARDAgent[6057]: libcoreservices: _dirhelper: 400: mkdir: path=/var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/C/ modes[2]=0700: Permission denied

    But I decided to go a more conservative route. I noticed that on my other machines that directory had different permissions. I logged enabled root and logged in as root in terminal. Then I set the permissions on that directory to match those on the machine ARD is working on.

    chmod 751 /var/folders/zz/zyxvpxvq6csfxvn_n0000000000000

    So far that is working for me.

    Aren't those folders SIP protected ?

    For me the issue happened after a disk crash and a restore from Time Machine.

    I'm sure TM is bug free and I am doing smth stupid. Yea right.

    But in the end I chose to go with a clean ElCap image.

    The folders are SIP-protected indeed, but you can do everything and anything from the recovery partition, using the Terminal there.

    (now you can do a lot of damage from there too :-> )

    Running 10.10.5 and recently started getting the Remote Desktop error as others here have experienced.

    Screen Shot 2016-03-22 at 10.10.04 AM.png

    Tried reinstalling Remote Desktop 3.8 from App store.... did not fix error

     

    Tried removing /var/folders/zz as suggested... did not fix error

     

    Tried reinstalling ARD Agent (Download Apple Remote Desktop 3.8.5.1 Client)... did not fix error

     

    What did work for me:

    Delete Remote Desktop application

    Delete System/Library/CoreServices/RemoteManagement/

    -then

    Reinstall Remote Desktop 3.8 from App Store

    Reinstall Remote Desktop Client 3.8.5.1

     

    Although I lost all of the saved logins to all 84 machines, ARD successfully launched and asked to reset the Admin Password.

     

    Working as expected now.
