Applications/memory Options

[Maccabee]

my question is, does instalalling programs or applications actually slow down your computer at all?

And there are some more more conditions. There arent any shortcuts to the program, and the program doesnt make anything boot at startup. It is just a program that opens when you want it to.

Does it use memory? Or only hard drive space?

Edit: O and compare with mac and pc. I didnt take into consideration the fact that a pc has a registry but a mac doesnt. So installing a program on a pc makes the registry larger which may in turn, slow down your computer.

pd: you can turn off that notification if it really annoys you.
