Mac OS X installation services are sometimes required by users when a lot of unnecessary settings have accumulated or software that is no longer needed or even malicious. Viruses are now being written not only for Windows. When the operating system is used for a long time, it starts to work slowly.

Sometimes there are unsuccessful updates and a failure occurs as a result of the computer cannot boot.
