Crashs liés à l'accès à distance ?

Je déteste parler comme tout le monde. Je pense que quelqu'un a accès à mon ordinateur, probablement la personne qui me l'a offert. Je ne pense pas que ce soit en dessous de lui, ou de quelqu'un d'autre.

Des astuces pour trouver un utilisateur caché via le Terminal.

Je jure que je viens d'allumer l'ordinateur et que l'écran a clignoté plusieurs fois en montrant différents paramètres de partage actifs, mais ensuite, lorsque j'ai accédé aux paramètres du système, il était revenu à la façon dont je l'avais configuré. Ce qui, je l'espère, empêchera quiconque d'y accéder.

Comment puis-je vérifier via le terminal si quelqu'un se trouve sur mon ordinateur. Il n'est qu'en ma présence physique, mais il brûle sa batterie complètement chargée en moins de deux heures.

J'ai eu ce crash et j'ai pensé qu'il pourrait être pertinent pour le scénario actuel possible.
