 Since the FIWARE Device Simulator CLI tool uses the [logops](https://www.npmjs.com/package/logops) package for logging, the logging level can be set using the `LOGOPS_LEVEL` environment variable. On the other hand, the logging format can be set using the `LOGOPS_FORMAT` environment variable.
 
-**NOTE:** There is an [issue](https://github.com/abbr/deasync/issues/55) in the `deasync` Node package which breaks fast-forward simulations which make use of the `attribute-function-interpolator` in MacOS machines. It works fine in Windows and Linux machines. So in case you are using a MacOS machine and need to use this functionality, we recommend creating a Docker image including the FIWARE Device Simulator and running the command from the container.
+**NOTE:** There is an [issue](https://github.com/abbr/deasync/issues/48) in the [`deasync`](https://www.npmjs.com/package/deasync) Node package which seems to break fast-forward simulations which make use of the `attribute-function-interpolator` in combination with entity attribute references (this is, `${{<entityId>}{<attributeName>}}` provoking a segmentation fault error. A workaround to avoid this issue is the use of global state variables updating the value of the attributes which need to be referenced and assigning their value to global state variables which make it possible to access them from any other `attribute-function-interpolator` instance.

                 * It is important to note that global state variables (this is, amongst `attribute-function-interpolator` instances no matter their specification or associated Javascript code) and local state variables (this is, amongst `attribute-function-interpolator` instances with the same specification or associated Javascript code) can be combined following the guidelines detailed above. Notice that local state variables will impose over global state varaiables. This is, if a `attribute-function-interpolator` uses a local state variable with the same name as a global state variable, the local one will preserve and apply.
                 * A valid attribute value using the possibility to maintain local and global state amongst `attribute-function-interpolator` interpolator executions is: `"attribute-function-interpolator(/* state: counter = 1 */ module.exports = { result: ${{Entity:001}{active:001}} + counter + globalVar1, state: { counter: ++counter, globals: { globalVar1: ++globalVar1 } } };)"`, where the result of the evaluation (this is, the value assigned to `module.exports.result`) will be the result of adding to the value of the `active:001` attribute of the `Entity:001` entity an increment equal to the times the interpolator has been run plus the value of the `globalVar1` state variable (which, on the other hand, is incremented globally in 1 before exiting the evaluation of the Javascript code).
