So I have a macbook pro running 10.10.3.
I am still using the default screensaver, which (when the computer was new) said
[MyName]'s Macbook Pro followed by an image of the apple logo.
After a few weeks of owning the computer, the screensaver just changed, seemingly on it's own, to say
[MyName]'s Macbook Pro (2).
Since then, as time has been passing, the number in those parenthesis have been incrementing, and today I am up to
[MyName]'s Macbook Pro (4).
Does anyone know what is causing this?
