In this lesson, we're going to talk about various system utilities that are found all throughout Mako's
that are important applications for makk system administrators to be familiar with.
So the first utility I'm going to show you is the classic about this Mac, about this Mac has been around
since the very early days of Mac OS and it's found right underneath the Apple menu.
And we bring this up, it shows us a number of different things, the model Mac, that you have, as
well as memory graphics, processor and so forth, your serial number is listed here as well, gives
you information on your displays, hard drive storage.
Support things like your help and the access to the user manual for your particular model and then also
service, and I thought I thought this was really neat.
If you click on this and it allow, it's going to go ahead and open up Apple's website for checking
your coverage so you can enter your serial number in here.
Put on our code here.
And continue, basically what it does is it checks to see if your machine is still covered under apple
care or any other kind of support.
So you can see mine's actually expired, but it does provide me with that information.
So if it turns out that, let's say it wasn't expired and I wanted to set up a repair, let's say a
warranty repair.
I also have a link here to go right to the Apple Store website nearest me and schedule that repair.
I'll close out of this.
We'll go back to the overview.
The other thing that's interesting in here that I want to point out is the system report.
So this used to be called system profiler and the older versions of Mac OS, but this gives you a lot
more information on the specific hardware and software on your machines.
So, for example, if you're used to Windows device manager, for example, this hardware section is
very similar to that.
You can click on things, let's say like memory, and I can see what my ram slots are, what speed they
are, what model DDR three sixteen hundred for example here and what slots they're in.
Same thing here with almost anything I've got.
My Bluetooth controller provides me all the information on Bluetooth and the hardware that I have inside
so you can take a look at this and it really gives you a lot more in-depth information on your particular
Mac hardware.
There's information here on the network side of things as well.
And then, of course, software.
So you click on applications, for example.
It's going to pull my machine and try to find out every single application that's installed on my Mac.
Very similar to probably Windows Add remove program section so I can cruise through here and see all
the various applications and what versions they are drivers and all those other things.
We'll go ahead and close out of that and close all of this.
The next thing I want to show you is how to force quit a misbehaving application.
Let's say, for example, that I've got the preview app and for whatever reason, it started giving
me the spinning beach ball or is just otherwise unresponsive.
And I need to get it to quit so that I can keep working in other applications.
So if you're used to Windows, you're probably familiar with control of delete to bring up the task
manager and kill the application or process that is hung on your machine.
In Mac OS, it's something very similar.
You can either choose the Apple menu and choose for Squit from here or you can use the keyboard shortcut,
which is command option escape.
And when you choose that, you either that from the Apple menu or use the keyboard command, you'll
see a list of all of the various applications that are running.
And I had mentioned that preview was not behaving very well.
So I'm going to select Prevue and I'm going to hit force quit.
It's going to prompt me.
It's going to tell me I'm going to lose anything that's fine and I'm going to hit force quit.
And now the application has closed and I'm free to relaunch it or continue to work in one of my other
applications.
Beyond being able to force quit an application, it's also sometimes helpful to see what other processes
are running on your back.
And so we do that with the activity monitor and I'll show you how to find that person up to the goal
menu and choose utilities.
Or you can also browse by going to applications, utilities and activity monitors.
The first one here on the left.
Go ahead and double click on that activity.
Monitor shows all the properties running on my map.
You can see all of these listed here.
You can click on them, your activity monitor itself.
You can get information on particular process, like on a creative cloud here, for example, and hit
the little eye.
And it shows me memory size, shows me other statistics, shows me open files and ports that Creative
Cloud is using.
So this gives me a lot of information on each individual process that's on my machine CPU usage and
those kinds of things.
So close all of that at any time.
And it's probably not recommended unless you really know what you're doing.
But you can select a process and you can hit the X right here and that will force quit that process
as well.
So that's activity monitor across the top, you've got other options, you can take a look at network
utilization by application sent bytes and things like that.
This disk IO, how much energy and application is using and how much ram the application process is
using.
So a lot of information here to diagnose if something's misbehaving on your on your Mac and either killing
your battery or causing problems with this GYO or other kinds of problems with performance.
All right, next up, we're going to talk a little bit about mapping a network drive, you may have
come across the time where you're going to need to map a network drive, maybe a file share from a server
or from another computer.
And you do that by using the go menu.
So you click on go and you go down to the bottom here, connect a server or you can hit Command K.
That opens up here, you have the ability to type in a path if you have other servers or devices on
your network that are broadcasting shares, you can also choose to browse.
The default for Mako's 10 in recent years has been SMB or Zomba sharing.
So it's fully compatible with Windows.
So in this case, I've got a retro PI share off of a Linux Raspberry Pi that that I have listed in here
that I can map to.
You can also save those servers by hitting plus down here.
I'll add it to your favorite server list.
You can also delete that from there and you can also clear all your recent servers, if you like, basically
just enter in.
The path to your share.
Now, one thing I will point out, if you're used to windows, they threw a little bit of a curveball
at you in Mako's.
It's actually forward slash for each one of these as you enter in your server that my domain dot com,
for example, and, you know, share, let's say, you know, that's my my share out there that I need
to map.
You notice here I've got forward slashes and windows.
You'll be more familiar with seeing something that starts with the backslash.
So one of the things I'll trip you up, if you're working in a multiplatform environment, someone may
send you a share.
And the path is actually in that that window style with a backlash is you just need to go through and
convert those backslash to the forward slashes.
You should have no problem connecting to the server.
Once you hit Connect, it will prompt you for the username and password.
And if everything is set up correctly from a permissions perspective on the server, you'll be able
to map the drive right to your desktop and it'll show up as another volume on your computer.
Next, I want to talk a little bit more about disk.
Utilities will go to go utilities and disk utility.
So we worked on disk utility in the Recovery Tools demo, and I want to take a few minutes to talk about
a few of the additional features that you can use disk utility with outside of recovery.
So this is the more streamlined interface for disk utility in Mac OS Mahaba.
And I want to show you a little trick here.
You go up to view you have options here, but by default it shows only volumes.
So you're only going to see Macintosh hard drive any external drive.
I plug in the USB stick here called Untitled.
It's a sixty four gig stick.
I'm going to go ahead and choose show all devices.
The reason for that is to show you that these there's actually discs here and then you can see this
is a formatted so you can see the container and then the volume inside the container.
And I think that's part of why they probably streamline this a bit.
And then here, this is really nice for the external drives because you can see what volumes you have.
You may have more than one volume on an external disk, and it's helpful if you need to interact with
the disk, lets say, to delete a partition that you can see the entire disk.
So I'm going to show you something here real quick.
First, I'll go in a partition so we can partition this drive any any way we want by default.
Here, it's fully formatted for Mac OS extended.
You can click on this and see we've got apps and we talked a little bit about apps before, but apps
and HFS Plus or Mac was extended and their variants here are required for installing Mac OS.
If you're going to install OS 10 on any kind of volume that has to be formatted for one of these, then
we have the MSDOS or Fat File system, which is the legacy file format for PCs, and we also have the
Tzfat or otherwise known as Fat Thirty two for creating a volume that can be read and written to on
Windows.
We can actually partition this out into a couple of different groups.
So I'm going to go ahead and do that.
I'm actually going to split this device in half.
So I end up with two thirty gig partitions by hitting the plus here.
I'm going to name the Mac side Mac OS and I'm going to name the Windows side.
Windows, and I'm going to change this to expat and I'm going to hit reply and it's going to go ahead
and partition the drive out for me.
And it's done.
So what I I can see here is I've got the drive here and I've got the two formats here for my two partitions,
OS and Windows now with X that I can actually read and write both from Windows and Mac OS.
So I'm going to use those Windows Drive actually just as a file drive.
In fact, I could probably rename it to data or something more descriptive than Windows, but I've also
got my Mac OS one here, which is where I'm actually going to install Mac OS on this.
That way I have a bootable Mac recovery drive and then I've also can use the same drive on windows because
I support two different environments and I may want to have a drive that I can on both machines and
save the save files, read files and things like that on either operating system.
So the reason why I pointed out that in view you want to show all devices, if I show only volumes and
I want to partition this drive into one drive and get rid of these partitions, if you go into partition
here, you'll see can't really modify this.
I'm stuck here and on the Mac OS one, I can partition.
I can subdivide the Mac OS side again if I want to, but I can't actually restore this disk to one size
one one four sixty four gig volume without going to show all devices clicking on that drive and hitting
a race here.
And then I can go ahead and erase it and reformat it.
One other thing, when you're interacting with disks instead of volumes is you also have an option to
choose your formatting scheme.
So Apple Partition Map is from the old non Intel Macs.
This was PowerPC.
You needed to have a drive that was formatted for Apple partition map if you were going to install and
boot off of Mac OS on a power PC based machine.
And then reboot record is for Windows so good as the newer OS 10 variants, we're going to keep that
as the default.
And then finally, if I go to do an install and I'll just launch.
The install Mac os Maharey.
I want to go through the install of the operating system on one of these drives.
I'll go step through this.
I can hit Schwall disks and you'll see here I've got my Mac OS one which I can install on.
And then if I try to install on the Windows one, it'll show that it's not formatted properly.
So we'll just put out of that.
Next utility we're going to look at is the terminal, and you can find that under utilities as well.
The terminal.
And terminal is basically brings up your Unix command prompt and allows you to work with, you know,
the Unix underpinnings of Mac OS 10.
We're going to be using the terminal a lot later in this course.
Sometimes it can be a little bit scary for those of you who maybe came up in a graphical user interface
environment.
But don't don't let the terminal scare you.
It's not that bad.
You will learn a lot of really cool things to do with it.
And I think you'll find that it's a very powerful tool, especially when you need to manage multiple
Macs remotely from one machine.
Well, we're talking about the terminal.
I also want to show a couple of other directories that you should be familiar with.
We're going to go to the go menu.
We're going to say connect to Folbre, and we're going to try a couple of different ones here.
So first, I'm going to do a bin.
And that's some of the Unix executables listed in here, so you can probably recognize some of these
here if you have any Unix background.
And the other one I'm going to do is go to.
Private.
Flash private, then again, these are all hidden folders that are abstracted away, similar to the
way the library folder was.
The user group.
But you can see here's where you've got things like your variable folder.
And in here you've got your 10 folder, for example.
So you can kind of cruise through these and see what kinds of things are in here.
Some of these you're going to have access to by default.
But this gives you an idea.
For example, what's the temp directory for Mac OS?
Well, it's actually at a private bar tab, Tempy.
And so you can empty this out or the machine basically cleans this up on a regular basis when it restarts
to.
But if you're looking for something in particular that maybe got copied to the temp folder, that's
how you would go about finding it.
Another thing I want to mention while we're talking about hidden directories is a place where there's
some additional applications that are kind of hiding out that you may need to get to from time to time.
And we'll just go to go computer so I can show you the full path.
It's under Macintosh Hard Drive System Library.
Or services applications.
Now, these are some of these like, for example, about this Mac we've already covered and you can
access these other places.
Archives Utility actually creates a zip file from any folder.
You can create a folder on the desktop through files and do it right.
Click on it and choose archive.
It'll automatically create a new zip file.
So it invokes this application when that happens.
So you may recognize this on the dock from time to time.
That's where it's launching out of as this area DVD player, maybe an application that time forgot.
I don't have a DVD drive in my Mac, but I still have a DVD player application here rather than it's
basically been demoted from the applications folder on any Mac that doesn't have one built in.
But perhaps I have an external one that I want to use or I want to rip a file and play it in the DVD
player application off the hard drive.
You'd be good to know where that's at.
And that network utility is extremely useful and so is wireless diagnostics.
This gives you the option to basically will go through and create a diagnostic report based on the wireless
network that I'm at and connected to, as well as other wireless networks around me.
That's really good.
If you're having problems getting a good wireless signal where you have a lot of interference, you
can start here to kind of diagnose without interference, maybe coming from.
And then I mentioned network utility.
I'm actually going to launch this a different way.
The best way to get to network utility if instead of remembering that path is to just go up here to
type in the spotlight or type in network utility and they'll automatically launch it.
So network utility is really handy because you can do these things from the command line with the config
commands and other Unix commands.
But this is also just as easy and probably faster in many cases.
So you have information here on your network interfaces and you can see our Ener1 sorry, you know,
in one into four different ports here to which being Thunderbolt, I don't have an onboard Ethernet
card, but if I did, that would be listed here as well.
I've got information on my network that I've got the ability to do ping right here so I can ping Apple
dot com, for example, and it'll start pinging.
So I can go and I can send only 10 things or I can do an unlimited number of pings.
Look up, I give you an honest look, look up here so that we do not come here for fun and there we
go by trace roots here as well.
So this is very, very similar to what you would expect from a command line, let's say, if you're
used to going into a Windows command line, typing in IP config and any number of commands after that,
you have those all right here in the network utility.
So it's often overlooked because it's just not easily found.
But a quick search using the spotlight will bring that right up for you.
