It's supposed to delete all the unnecessary caches, files and logs that pile up in the background. I ran the scan which went quite (~1 min) and it found a bunch of stuff equating to about 15GB! Unfortunetely the demo would only delete 200mb... The major memory eater was actually Spotify with 8GB! I do have some offline playlists, but only about 2-3 GB so that was very interesting to see.

Has anyone had any experience with this app? It could be worth buying the whole app if it deletes those unnecessary files without distubring any programs. Simba, maybe you've tried this one?

 

Just get another HDD

 

I like if it can make my computer more efficient though

But I'm waiting for the SSDs to drop in price. Mmmmm, faster and less energy demanding.

 

I've used it. A lot of the space comes from the deletion of unnecessary language files. I got ~12GB back. How much is the full version?

 

Virtually all of the system log files clean themselves up. If you want to run it manually, pop open a terminal, su to root (sudo su) and run the following:

periodic daily weekly monthly

Do not close the terminal until the shell prompt returns.

 

Get monolingual to dump the languages, and Onyx X for everything else. All free.

 

I think it was $30.

 

Excuse my lack of Terminal skills: what does "su to root" mean? Should I find my way to the folder in question?

 

It stands for substitute user; basically, you're borrowing the root user permissions.

 

su/sudo allows you to "become" root (or any other user) without actually logging in as that user. It's handy if you want to allow a given user to access the permissions of another user, without actually exposing that user's login credentials.

The phrase 'su to root' refers to either using su (become substitute user) or sudo (execute command as substitute user).

To effectively "log in" as root, you would use 'su root' and enter root's password. However, OS X does not allow root logins by default as a security measure, so in order to do this you would have to assign a password to root.

To do stuff as root without having to log in, you would use 'sudo su' and enter the USER password. You then essentially 'become' root in terms of file permissions and access, though you remain logged in as your usual user.

You can also use sudo to run commands as root without actually assuming all of root's permissions. E.g. 'sudo command' will execute a given command as root. Most people with UNIX underpinnings simply use 'sudo su' to become root and thereby be able to run any number of commands without prefacing each with sudo.

Once you're done with sudo (or su), you can simply type 'exit' to return to your user shell.
