I used this code on an app:
chmod 600 /Applications/Freedom.app ; chown 'whoami':staff /Applications/Freedom.app
Does anyone know how to undo this?

so i go and log into my root account on my mac. i did look up what the 600 means, but does that help me with what previously was the permissions? or can i just set it to chmod 777(which means everyone has all permissions)as far as i know? – TheBelgianWaffl _ Gaming Nov 16 '17 at 02:44

To undo the chmod use :
sudo chown -R alexandertollman:alexandertollman /Applications/Freedom.app
To set back to permission level 755 use :
sudo chmod -R 755 /Applications/Freedom.app
The whoami only prints the username associated with the current effective user ID.

Why did you make it recursive? You changed the permissions on a single file, so -R, is unnecessary – Ramhound Nov 16 '17 at 02:49

can someone explain what -R does? the only thing i know about it is when i looked up changing 'chown', it used -R for changing a group of files, the single file one did not have the -R in it. – TheBelgianWaffl _ Gaming Nov 16 '17 at 02:53

I already told you what -R does, and it isn’t what you said it was: https://superuser.com/questions/260925/how-can-i-make-chown-work-recursively – Ramhound Nov 16 '17 at 02:53

3[-R and —reference](https://i.stack.imgur.com/HF4GS.jpg) is two entirely different things. [You shouldn’t take my word for it though, so read the manual, on the command and take your own word for it.](https://linux.die.net/man/1/chmod) [Unix.com](https://www.unix.com/man-page/Linux/1/chmod/) would agree with me also. – Ramhound Nov 16 '17 at 03:04
