[Interest] QSharedMemory::create returns out of resources errors on a few macOS machines

[Alexander Dyagilev]

Hello,

Some rare uses keeps reporting that our app can't start due to this error.

We use QSharedMemory to keep track of running instances of our app.

It seems this is can be a known issue due to macOS limits. Here an 
article on how to lift them:

However... Did anybody here experience the same issue?

All I can think for now is that it's caused by some buggy software which 
exhausted macOS limits so our app can't function normally.
