Hi,

I got the following error every time when I try to run BOINC the second time, when ATLAS LHC@Home running. (Which uses VirtualBox.)

BOINC ownership or permissions are not set properly; please reinstall BOINC.
(Error code -1202 at /Library/Application Support/BOINC Data/projects/virtualbox)

Reinstall solves the issue, but I would prefer to able just lunch it. :)

I'm on Mac, BOINC version 8.0.2.
I tried to give permission on the mentioned folder to all, but it didn't solved the issue.

Thanks for your help!

I received the same error.
Mac OS Sonoma 14.4, apple M1.
Boinc 8.02

BOINCE ownership or permissions are not set properly; please reinstall BOINC.
(Error code -1202 as /Library/Application Support/BOINC Data/projects/virtualbox)

Re-install does work until my computer is restarted. Must repeat the re-install every time I restart my computer.

Never used a Mac so might be talking rubbish.

Two ideas. One add your user to boinc group. (This has been used to solve some problems inthe past on LInux and MacOS is a unix based system. I also wondeed about adding the user boinc to the VB group? Maybe if it doesn't help this will give some ideas to work on.

See here for instructions to add a user to a group.

To me this illustrates a problem with Macs in that the user is not encouraged to lift up the bonnet to see what is going on. Fine for the 9x% of users where everything just works. An issue for that small percentage who run something unusual enough that it does require tinkering.

Thank you. I hacked around that folder and

sudo chown boinc_master:boinc_project virtualbox

solved the issue.

Hmm... I celebrated too early. Worked for some restart, but now stopped working again, don't know why.
Tried also Dave's suggestion about adding my user to the group, but it doesn't solved either.

Close but no cookie eh? Hopefully, there are enough clues there to enable someone who actually knows about Macs to sort this out.

Edit: Is it possible to run with administrator privileges? Not a good practice in general but if BOINC is all you are using the machine for probably OK. Even if you don't want it for long term, it may give more information for someone who knows the OS.

I'm seeing the same problem as the OP. I tried to run the sudo command but got this error:
chown: virtualbox: No such file or directory

Same error.
After reinstalling, everything fine, but at reboot, the error reappears.
Some reboots may go smoothly, but seems random.
Tried 8.0.4 to no avail

Have you installed virtual box? You need to have done so to run VB tasks.

\pretty sure this error is down to VB set up and not down to BOINC version. Have you tried adding BOINC to the VB users group? Again, I am working a bit blind here guessing that it might be similar to issues with Linux as MacOS is Unix based.
