Hallo,

Ik ben nieuw op het forum en heb volgende vraag.

Sinds kort (= na de laatste update Yosemite) merk ik om de paar minuten een draaiend tandwieltje in de taakbalk (zie screenshot hieronder).

Als ik snel genoeg ben om erop te klikken zie ik de naam 'helper' en een kruisje om het te sluiten. Na het afsluiten start het echter na een tijdje vanzelf weer op.

Vraag :
- wat is dit ?
- kan het kwaad ?

Groetjes,

Kirre

Dat tandwieltje in de taskbar zie ik niet bij mij.
Misschien heb je "iets handigs" geinstalleerd?

Je zou hier een EtreCheck overzicht kunnen plaatsen om te zien wat er aan de hand is.
