Question about downloading programs...

I just got a brand new macbook and want to keep it running as smoothly as I can. I want download a game which is about 10gb's big. If I download this game, use it for a bit, and then delete it after a month or so, will my computer still run as fast as it did before I downloaded the game? Or will there still be a little lag or something left over even if it's off my harddrive.

Who knows? Is it a legal download?
No reason for it to affect things really.

yeah it's legal haha. just someone recently told me that even when you delete a program or something off your hard drive, it'll never be as fast as it was before you downloaded it. so i dunno if i should be holding back on downloading things that take up a lot of space, like games and movies.

If u want to get rid of the game then use App Cleaner or similar app and it will pick up associated files for trashing. see here Download AppCleaner for Mac - Uninstall your apps more easily. MacUpdate Mac Software Downloads

alright that should be good, thanks for the replies!

Most programs don't leave enough stuff behind to worry about. There may be a preference file or two left behind in the /Library/preferences folder. There are programs such as AppZapper that try to remove all traces of a program.

I download a lot of stuff to try etc. and haven't really noticed a problem.
