What I am going to tell you in this article, you may never have to do, sometimes and depending on what faults you may have on your Mac, the Apple technicians you contact through their customer service phone will tell you they request.
It's about knowing where we need to go and what we need to do in order to send Apple a system or Spotlight diagnostic. This situation can occur if your system begins to have an anomalous behavior and perhaps, even formatting the equipment you still have this malfunction.
Apple thinks of everything and has prepared a place in the system, more specifically within the Activity Monitor, where we can subject our system or the Spotlight system to an inspection. This diagnosis generates files that will later be sent to Apple so that designated workers can try to find the fault.
If the thing still does not prosper, it is time to continue with the next step, which is to take it to an Apple Store or an official technical service so that the specific diagnostic tools created by Apple itself can be passed to the team.
In order to run the diagnostics I'm talking about, you must enter Lauchpad> Others> Activity Monitor and at the top of the window that appears you could see a button with a gear. When we click on that gear you will see the two diagnostic possibilities.
We have to bear in mind that as a lot of data is going to be sent to Apple, they are healed in health and they show you a window that we have to accept where you inform yourself as a privacy contract of what we are going to send. When we accept the process begins, which takes its time, and ends up generating the file that we have to send.
