text: Title: Ulimit low on MacOS, but incorrect way to update it
  Body: ```
  Open file descriptor limit (256) is low. File sync to remote clusters may be slow. Consider increasing the limit using `ulimit -n <number>` or modifying system limits.
  ```
  
  But on MacOS 15 you can not do that anymore
  
  ```
  $ ulimit -n 4096
  $ launchctl limit maxfiles
  
  	maxfiles    256            unlimited
  ```
