Console on Mac

Hey guys, there's mad kids on the one. Today I'm going to be teaching you about an application located on your computer called Console.

You may or may not know what Console is. Basically, what it does is it shows you the logs of your computer. Now my friend thinks that if you clear your console, it might speed up your computer a little bit. Now I'm gonna be explaining to you why.

So first of all, if you need to find your menu, just click on and find your window. Whatever then go up to Go, go to folder, then type /Applications/Utilities. Okay, and we'll have that path in the description of this video. Now you want to locate an application called Console, then you open this up.

So here's your Console, and right here if I say "Show Log List," here's our console messages. You can, um, since I'm not root, I can't select "Move to Trash," but with a bunch of log files, I can just move them to the trash like this one. I can just move to trash and it will save a bit of space on your computer.

And so if you move them to the trash, also Console will have a line from every program. Like here's some ScreenFlow logs, ScreenFlow right here, there's Finder errors, okay? Log in, log, it's a bunch of stuff. Sudo, lots, a bunch of stuff.

Like it says I tried to sudo from my Mac into the one user, and I'm not on the sudo. It even says what console I was, I was on and when I want, what the command was. Right here you can see.

So that's that. There are a bunch of errors in here. Also, system.log is not admin. You don't have permission to read system's log file. Also, if you want to have the permissions, you can just quit Console, open Terminal, and yes, execute a sudo command or just log in as root, however you want.

I'm just gonna type log in and hide my username as root and my password. Okay, so now I'm logged in as root. All you have to do now is type cd /Applications/Utilities/Console.app/Contents/Resources/. Then you type ./ that will open up Console as root.

I say "Show Log List." I do have permissions to read the system log, and I can move it to the trash to save a little space on my desk. The reason that it'll speed up your computer a little bit is if the logs get too big, and your computer keeps on them trying to save and add stuff to that file.

They have to rewrite the whole entire file in order to just get another line on the file. The bigger the log file gets, the slower it gets writing. Eventually, if it's pretty big or it just physically cannot write to the log, because your hard drive is totally used up, it just won't work.

Which is why occasionally, you should just move your log to the trash or get rid of a few lines of it or something like that. I like to do that every once in a while. I'm not gonna move it to trash right now. Here's logs from my library, from loot, etc., and I can just meet logs, whatever.

So this is Console. It's actually a great way if Time Machine craps out on you. It'll put a nice little error number right in here, and you'll be able to find the error number online, and they'll figure out why exactly Time Machine is not backing up.

That has happened to me a few times, and all those times I've gone into Console since, check the error number, etc. If you haven't already, watch your terminal lessons, because if you don't understand this very well, you should watch our terminal lessons.

Also, if you are an administrator, you will be able to read the system log. So Console is all about logging stuff. It may or may not make a computer a little faster clearing your logs, but most of the time it really won't. But it's a great tool, and I suggest it to anyone who wants to easily be able to read all the logs that really matter on your computer.

So that's how to use Console app on your Mac. So please subscribe to Mac isn't one thing, get back.
