Hi Valentina,
I’m sorry to hear this. The cause of the problem probably that you are using Mac OS Ventura.
There are several issues with it.
For example, as it is reported in this thread:
Toolbar issue on MacOS Ventura - snap / Problem Reports - STEP Forum (esa.int)
Unfortunately, we can’t fix this in the short term. This can only be addressed with the next release in summer. Till then you can either rollback to the previous Mac Os version or us SNAP in a virtual machine.
