Hi all,

The newest versions don't install correctly on my iMac (Intel).
I can't recall what went wrong with 8.2.8 but with 8.2.9 it showed the incorrect permissions error launching the app after the installation.
Another observation: The BOINC Manager app became an Alias.
Maybe, it results from having moved the BOINC data to a separate SDD.
Reverting to 8.2.5 fixes the issue.
If you need more details, I'll happily reinstall 8.2.9 and send logs or try tricks to solve the problem.

Kind regards,
Felix

Try the new 8.2.10 alpha release and let us knowif it works.

For any insight, check my BOINC Development Blog.

For what it's worth, 8.2.9's running perfectly happily in macOS 13.7.8 on my own Intel iMac, as did 8.2.8 before it.

Sorry for not responding. I was busy with work and then had a bike accident.

I installed 8.2.11 just now with the same result.
"Der Besitzstatus oder die Berechtigungen von BOINC sind nicht korrekt. Bitte installieren Sie BOINC neu.
(Fehlercode -1071)"

I'm rolling back to 8.2.5.

Do you think uninstalling and re-installing may fix the issue?

I am not sure if uninstalling removes everything on a Mac. (It doesn't always on Windows) If trying the uninstalling route, it is worth making sure all configuration files are removed before reinstalling unless someone with actual Mac experience tells me I don't know my fundament from my funny bone.

It was kind of helpful to uninstall BOINC because the error message probably points to the solution.

"Sie sind momentan nicht befugt BOINC zu verwalten.

Um BOINC mit dem aktuellen Nutzer auszuführen müssen Sie:
- BOINC neu installieren und die Frage bezüglich
"non-administrative users" mit "Ja" beantworten
oder
- Ihren Administrator kontaktieren damit Sie in die
Benutzergruppe 'boinc_master' aufgenommen werden."

I tried the second option but now I have permission problems with the data directory.
First with projects. I granted myself rw permissions but ran into the second error below, having to re-install BOINC.

"Der Besitzstatus oder die Berechtigungen von BOINC sind nicht korrekt. Bitte installieren Sie BOINC neu.
(Fehlercode -1200 bei /Volumes/Obelix/BOINC Data/slots)"

Editing permissions so my user has read and write permissions leads to:
"Der Besitzstatus oder die Berechtigungen von BOINC sind nicht korrekt. Bitte installieren Sie BOINC neu.
(Fehlercode -1071)"

I'll investigate that further on Sunday evening or Monday morning.
Should my user be member of the group boinc_projects?
Side note I have a permanent spinning wheel instead of the name for a user or a group in the permissions section of the informations for boinc directories.
