tokend support is NOT broken Catalina

Upgrade regression

3 weeks ago I wrote the article "tokend support is broken Catalina 10.15.1" because I could no more use the tokend I am working on after the upgrade from Catalina 10.15.0 to Catalina 10.15.1.

Fake news?

Today I upgraded to Catalina 10.15.2 and the problem is still present.
To be sure I installed OpenSC and the tokend from OpenSC works fine on Catalina 10.15.2. Good job OpenSC team.

So the problem is not Catalina but my tokend.
I then noticed a line in the system logs:
kernel Sandbox: securityd(638) deny(1) process-exec* [...]

I have a problem with the tokend sandbox and need to fix it. The problem is on my side :-(


I wrongly accused Apple to have introduced a bug in macOS. I am sorry for that.
Next time I will double check the problem is really not on my side.
