Mac High Sierra Location For Devices

Back in the early days of the Internet, things weren’t quite as stable as they are now so system administrators created a suite of tools to help troubleshoot issues. Many old-timers wistfully remember the “fun” of typing in a ping command at the command line followed by an IP address, then waiting to see whether there was a response.

The next version of Apple’s operating system for the Mac is called macOS High Sierra.While the OS is mostly about software refinements, it also lays the foundation for future innovations in.

Likewise, traceroute was always useful for finding out where in the long chain of bounces between computer, routers and servers that communications between machines was breaking down. Apple put all of these useful tools into a single app called Network Utility, which up until 2014 could be found residing in the Application > Utilities folder. So where is Network Utility hiding these days, and how can it be used to troubleshoot network problems?

Where In The World Is Carmen Sandiego Network Utility?
If Network Utility is no longer in the Utilities folder of the Mac, where is it? Looking at the path to the app, it’s hidden away in:

/System/Library/CoreServices/Applications

There are three much easier ways to find Network Utility and launch it without digging around in hidden folders. The first is to go to the Apple Menu, select About This Mac…, click on “System Report”, and then select Network Utility from the Windows menu. The second is even easier; click the Spotlight search icon (it looks like a magnifying glass) on the right side of the Mac menu bar, then type in “Network Utility” and press the return key. The last way? Just ask Siri — say “Launch Network Utility” and the app is immediately on your screen.

Network Utility and Info

Network Utility’s individual components can also be accessed from the Unix command line in Terminal, but that’s “beyond the scope of this course.” Just suffice it to say that if you really want to know the gory details of a command, you can type in “man name-of-command” (i.e., man netstat) and not only find out how to access that tool in Terminal, but all of the many options available.

Let’s look at each of the useful tools in Network Utility and how they can be used in troubleshooting.

Info
Info (see the image in the previous section) provides a drop-down menu that lists each of the network interfaces that are built into your Mac. For example, my late 2015 iMac shows Ethernet (en0), Wi-Fi (en1), Thunderbolt 1 (en2) and Thunderbolt 13 (en3). Selecting any one of those network interfaces provides a wealth of information, including the hardware address (MAC — Media Access Control address, a unique number assigned to each network interface), the IP address (IPv4), link speed, link status, vendor, and model.

The right side of the Info screen also shows how many data packets have been sent or received by the interface since the last time the Mac was restarted. If a number of errors or collisions are visible, there’s a good possibility that there’s a poor connection that is dropping packets. This often manifests itself as a slow connection to websites, slow downloads, and so on.

Netstat
Netstat is a bit esoteric for most Mac users who aren’t network administrators. It provides a way to examine your Mac’s network routing tables by displaying a summary of packet types sent and received using common network protocols – TCP, UDP, IP, ICMP, IGMP, IPSEC, IP6, ICMP6, IPSEC6, and PFKEY.

Network Utility – Netstat

Ping
Probably the most widely-used and useful tools in Network Utility is ping. It’s used to see whether your Mac can communicate with another device with a known network address — otherwise known as “pinging” that other device. For example, if I’m at my iMac (local network IP address 10.0.1.6) and I want to know if I can reach my AirPort Extreme router (local network IP address 10.0.1.1), I type the address I wish to ping into the field on the Ping pane of Network Utility, then click the Ping button.

Network Utility – Ping

By default, ping sends 10 packets to the other device, measuring the amount of time it takes for each ping to be received back at the iMac. If the response shows a timeout on any or all of the pings coming back, it indicates a bad connection between the Mac and the router, and I can start troubleshooting issues armed with that knowledge.

Lookup
If it weren’t for Domain Name System (DNS) servers, we’d all be typing numeric addresses into our web browsers to get to websites. DNS converts web addresses — like blog.macsales.com — to IP addresses so that our computers can carry on a conversation with a web server. Sometimes you may type in a web address and get a “server not found” error from the web browser. This usually indicates that you mistyped the address (like “blurg.macsales.com”), that there might be issues with the DNS server, or that that the DNS server address (entered in Network preferences) might be incorrect.

Lookup actually encompasses two underlying commands — nslookup and dig. Typing in an alphanumeric name for a website — say “apple.com” and clicking the Lookup button shows IP addresses that are associated with that domain name, while entering an IP address displays domains that are associated with that address. Oddly enough, entering the IP addresses that appear for “apple.com” returns “applecentre.info”, “AirTunes.info”, and “carbondating.com” as three possible domains. The first two addresses take you to the “apple.com” website, while the third goes off into oblivion. My guess? Apple uses these odd domain names as a way to fend off distributed denial of service attacks against the company.

If your address belongs to remote area, customer will need to pay remote handling cost or we will change to ship by EMS. Usually we declare a lower price on DHL invoice to help with customs clearance. Please remember to leave message if you have any special requirement.Yanwen Express: 5-10 working days.

Network Utility – Lookup

Traceroute
One of the most useful tools in Network Utility is traceroute, which does exactly what the name implies — it traces the route between your Mac and another machine. Let’s see what happens when running traceroute from my iMac to the United States Patent and Trademark Office (uspto.gov).

Network Utility – Traceroute

Things start off on my local network (that 10.0.1.1 is my AirPort Extreme Wi-Fi router), then go through various Comcast systems to the Dallas, Texas area, then off to Washington, DC (wswdc) on the ATT network. Traceroute is fun in terms of just showing what a wild ride packets can take between your Mac and a web server.

Whois
Ever wanted to know what entity is behind a domain name? That’s what whois is all about. While many organizations now purchase privacy for domain name registration information, it’s still possible to find the domain registrar used by a website. This can be quite useful if you’re receiving spam from a particular email address and wish to complain to the domain registrar.

Finger
Think of finger as whois for individuals. Fortunately, it doesn’t work as well as it once did back in the original days of the Internet, when it was helpful for finding out who exactly was hiding behind an email address. Nowadays, a finger of a user name and domain address is likely to time out. That’s a good thing…

Port Scan
The last tab on the Network Utility window is Port Scan, useful for determining the status of various internet protocol ports on a particular machine. While your Mac is assigned a specific IP address, the various services that it uses — email, web browsing, and so on — are each assigned a TCP or UDP port number.

In a very secure world and on a very secure Mac, all ports would be closed — that’s the purpose of a firewall, which acts as a gatekeeper for a particular port and only allows specific traffic to enter through that port. But what you’ll find is that some ports are open — on this scan, I turned off my Mac’s built-in firewall (found in System Preferences > Firewall) and found that a number of ports were open:

Network Utility – Port Scan

To see what a particular port is used for, here’s a complete list. What I found is that some of the ports (445 and 4502) are used for Windows sharing and Silverlight; turning the Mac’s firewall back on did nothing to close those ports, which are apparently required by some of the apps that I use on this machine.

So there you have it! Not only is Network Utility still on your Mac, but it’s still a surprisingly useful tool for troubleshooting network issues.

Apple is preparing for macOS 10.13 High Sierra, the newest version of its Mac operating system, which is supported on the Mac mini, iMac, Mac Pro, MacBook, MacBook Air, and MacBook Pro. There are a few big features coming our way and lots of under-the-hood fixes as well. We have all the info you need about what it is and when it's coming right here.

What's new with macOS High Sierra?

Sept. 12, 2017: macOS High Sierra public launch available Sept. 25

Apple spent the better part of two hours talking about its latest line of iPhone 8 and 8 Plus and the iPhone X at its fall event. This is no surprise considering it's dubbed the iPhone event. Though Apple also mentioned the new Apple Watch, and upcoming features in watchOS 4, not a peep was mentioned about macOS High Sierra. Does this mean Apple is planning a special event just for macOS? Probably not. It just didn't merit any special attention this time around.

The good news is that Apple quietly added a release date for High Sierra on its website. The final version will be available September 25, the same day that the new iPhone and Apple Watch line will be available in stores.

August 23, 2017: Flagship creative apps will need to be updated to work with macOS High Sierra

Apple has published a new support document that details the compatibility of the company's professional apps with macOS High Sierra. Final Cut Pro X, Motion, Compressor, Logic Pro X, and MainStage will all need to be updated to their most recent versions in order to run on High Sierra:

• Final Cut Pro X 10.3.4 or later
• Motion 5.3.2 or later
• Compressor 4.3.2 or later
• Logic Pro X 10.3.1 or later
• MainStage 3.3 or later

Earlier versions of all of these applications are incompatible with the new operating system.

What, why, when, and how to get macOS 10.13 High Sierra

What is macOS 10.13 High Sierra?

macOS High Sierra is Apple's newest version of the desktop operating system. This is its second version under the new nomenclature, macOS. Last year, Apple made the switch from OS X to macOS, much to our surprise (not really).

Why High Sierra?

High Sierra is technically a minor update to macOS Sierra, though the new features are pretty amazing. So the idea is that Apple went higher with its already great Sierra operating system.

When can I get my hands on it?

macOS 10.13 High Sierra is available as a beta for developers and as a public beta right now. If you're not a developer, and don't want to risk testing the public beta, you'll be able to download it for free this fall.

If you plan on downloading the developer or public beta, be smart about it: If you only have a single Mac, make sure you create a partition to run beta software, or install on a secondary Mac you don't rely on for everyday use.

The final version, the public version that is no longer in beta, will be available September 25 as a free update in the Mac App Store.

How do I upgrade to macOS 10.13 High Sierra?

Apple makes it really easy to upgrade to new versions of its operating system across all devices. If you're unsure how to get the latest software upgrade, we have you covered with a comprehensive guide.

My Mac is old, can I upgrade to macOS High Sierra?

The latest Mac operating system will run on the following devices:

• iMac (Late 2009 & later)
• MacBook Air (2010 or newer)
• MacBook (Late 2009 or newer)
• Mac mini (2010 or newer)
• MacBook Pro (2010 or newer)
• Mac Pro (2010 or newer)

Will there be any features that won't work on my older Mac that is listed as compatible with macOS High Sierra?

Similar to El Capitan and Sierra, if your Mac was built prior to 2012, you won't be able to take advantage of the Metal Graphics framework and many of the Continuity features, but the rest of macOS High Sierra should be just fine.

How much is this new software going to cost me?

Nothing! Apple stopped charging for software upgrades quite a few years back. macOS High Sierra is a free update for all iMac, Mac mini, and Mac laptop computers that are compatible.

OK, so what are the new features coming to macOS High Sierra?

The short answer is HEVC support, APFS support, better graphics, VR support, and some fantastic app improvements. The long answer is below. Read on for details.

What the heck is HEVC?

HEVC stands for High Efficiency Video Coding. It's also known as H.265. It's a new standard for video compression that is about 40% better than the current H.264 standard. It compresses 4K video much faster and more efficiently and improves video bit-stream. It also uses less bandwidth so you can stream higher quality video in places where your internet speeds are lower. Video file sizes are much smaller, and so take up less storage space on your Mac.

Basically, HEVC is way better than H.264 for video compression and you're going to love how fast you can stream 4K movies without any lag.

Why is Apple File System such a big deal?

Every computer uses some form of file system. Imagine your Mac has a filing cabinet that a little guy goes to every time you open a file or search for something. Let's call him 'Apple.'

Apple's current file system, Hierarchical File System Plus (HFS+), works great, but he came up with his organization system more than 30 years ago. Even though he updated it about 20 years ago, he didn't actually clear everything out and start fresh. He just made some changes so he could file stuff faster and find stuff easier.

Fast-forward to today, where Apple has designed a new way to organize and keep track of everything in your Mac. He got a new filing cabinet, better locks, and even added filing cabinets for your iPhone, iPad, and Apple Watch. He also got those file folders that can be adjusted wider so he can fit more files in each one, and changed the paper weight of current files so they are thinner and more of them can fit into a folder.

What this means for you is that you'll be able to access and load your files much faster, encryption will be much stronger, duplicating files will happen in a blink of an eye (even large video files), and you'll have protection from crashes thanks to metadata copying.

Basically, it's going to make your Mac feel brand new again, and if your Mac already is brand new, it's going to make it feel like you just installed a turbo engine.

So, better graphics?

That's correct. Apple has suped up the Metal graphics processor by adding machine learning, external GPU support, and virtual reality.

Metal 2 focuses on GPU support over CPU, so things will load and process faster — up to 10 times faster, according to Apple. This is great news for game developers and might (hope, hope) open the door for more PC games to make their way to Mac in the future.

macOS High Sierra will support external GPUs, too. So even your baseline MacBook will be able to support heavy graphics programs in the future.

Wait .. Did you say VR support?

Oh, yeah. The Metal 2 framework will make it possible for developers to create virtual reality games and macOS High Sierra will make playing virtual reality games on Mac a reality.

The iMac with 5K Retina display and the iMac Pro will natively support VR. Plus, thanks to macOS High Sierra, you'll be able to add an external GPU seamlessly and play VR games. Valve has even decided to add SteamVR to the Mac.

What about the apps? Did Apple update any apps?

It sure did. Apple added some nice improvements to Photos, Safari, and Mail. There are also some pretty sweet additions to Notes, FaceTime, Siri, and iCloud. Read on to find out more.

Photos

Photos has a few redesign features, a couple of great new filters, some cool editing tools, and looping Live Photos.

• Expanded sidebar - The sidebar is now always on to make searching for your photos a lot easier. The photo Import view shows all of your past imports in chronological order, similar to your standard Photos collection.

• Better organization - You can filter photos by different criteria. There is a selection counter that will let you drag and drop multiple images into an album or import them to your desktop.

• Better editing tools - You'll be able to adjust the contrast and color options for your photos just a little bit better with Curves for fine-tuning and Selective Color for saturation. Oh, and there are more photo filters now.

• More Memories categories- You'll get more automatically generated Memories based on different criteria. For example, you'll get beautiful slideshows from your first anniversary, or scroll through pics of your pets.

• Live Photos Extreme - Live Photos have been super charged with editable Loops, Bounce, Long Exposure (my favorite), trim, and mute. You can even select a key photo for each Live Photo, which will be the single non-moving image people will see before they touch the photo to watch it move.

• Better third-party app support- Third-party apps are better integrated with Photos in macOS High Sierra. You can select a photo, open it in a third-party app, and make your edits. Those changes will automatically be saved in Photos. You won't have to re-save new edits. App extension support has also gotten bigger with more apps.

• Bigger faces - The People album has larger thumbnail images for faces and group pictures better. If you're signed into iCloud Photo Library, your People changes will update across all of your connected devices.

Safari

Safari's biggest update is with Intelligent Tracking Prevention. It uses machine learning to find cookie trackers and stop them from following you from one website to another. So, you won't be as likely to see an add on one website for a product you just looked at on another website.

Safari in macOS High Sierra also implements an autoplay auto-block tool. Basically, if you visit a website that has an add or video that is set up to automatically blast you with noise, it won't play automatically on Safari. Blocked!

Speaking of blocked, Safari in macOS High Sierra lets you personalize what your browsing experience looks like with each website you visit. You can enable Reader View, content blockers, page zoom, and auto-play blocking. It's in the same section that used to house Reader View.

Oh, and Safari is even faster than ever before. Zoom, zoom!

Mail

When you search in Mail in macOS High Sierra, the most relevant results will appear as 'Top Hits' so you can find what you're looking for faster.

You can also use split-view when composing mail. Productivity increased!

Siri improvements

Apple gave Siri a boost in macOS High Sierra with a more expressive voice. It has better tone and talks more realistic. Personally, I like it when Siri tells a joke in a super robotic voice. I think it's funnier.

Siri is also able to learn about your music interests by connecting to Apple Music. You can ask to 'play something to help me relax' or 'make me a party playlist' and it will play songs based on your previous Apple Music activity. In macOS High Sierra, Siri also knows a lot more about the music you're listening to.

Sharing in iCloud

When you save a file in iCloud Drive, you can share it with others, just like you do in the Notes app. Using the Share tool, you can send people an invitation to edit and everyone that's using the supported app can collaborate in real time.

Apple has also added iCloud Family Sharing, which means you can invite family members to share your iCloud storage instead of everyone having their own account. iCloud Family storage plans include 200GB or 2TB of storage, so you can load up all of your photos, videos, and more.

Search for flight info with Spotlight

When you enter your flight number into Spotlight, it will search your system for all the information you need to get there on time, including arrival and departure times, terminals, gates, delays, and airport maps.

In macOS High Sierra, Spotlight also supports constellation information, celebrity facts, and lots of Wikipedia results for those really elusive bits of knowledge.

Notes

If you use a particular not a lot, you'll be able to pin it to the top of your list so it doesn't get lost in the mix every time you update another note. Keep it at the top and it'll stay there, right were you left it.

Notes also gets tables in macOS High Sierra. It's sort of like a mini spreadsheet for keeping track of things like expenses, party invitees, and wedding plans.

FaceTime Live Photos

Have you every had a moment when you're FaceTiming with your family when someone does something so cute or so funny that you wish you could have captured it? Well, now you can. In macOS High Sierra, you'll be able to take Live Photos of the FaceTime window, and this is on the Mac, which will automatically save to the Photos app. And, before you think about taking a Live Photo without your dad knowing, you'll both get a notification when one is taken.

Messages in iCloud

That's right. Your chats, those ones you don't want to delete because they hold a special place in your heart, will no longer disappear if you download a fresh copy of an operating system. All of your Messages will be stored (encrypted on both ends) in iCloud. So, when you start using a new device, your chats with mom from a year ago will still be there.

The bottom line

Though macOS High Sierra doesn't seem like much on the surface, the under-the-hood improvements are huge. With advanced file systems, better graphics and video compression, and support for VR, your Mac is really finding its stride.

If you have any questions or comments, please put them in the comments and we'll try to answer them as best we can, as we learn more about macOS High Sierra.
