May 25, 2020 Question from Chris B: I’d really like to have a Mac, but since I can’t afford one I’d like to build a computer and install Mac OS on it. I know people build their own Windows PCs from scratch all the time. Can you tell me how to build my own Mac? I have $500 that I can spend on it. Key APIs from the Macintosh Toolbox would be implemented in Mac OS X to run directly on the BSD layers of the operating system instead of in the emulated Macintosh layer. This modified interface, called Carbon, would eliminate approximately 2000 troublesome API calls (of about 8000 total) and replace them with calls compatible with a modern OS. @Donal the filesystem would be Lion's default which is Mac OS Extended (Journaled) – Rodney S. Foley Aug 21 '11 at 19:47 maximum filename leght was in 10.6 255 and maxumem path length was 'unlimited' - wouldn't expect that it got smaller with Lion.
When you create or copy a file to your Mac, it is assigned a path which is the actual location of the file on your Mac. Paths let you easily get to any folder or files on your machine as they represent the full address of the file saved on your machine.
Sometimes you may want to reveal the path of a file on your Mac for various reasons. Maybe you are writing a program that takes the file path as an input. Or maybe you have installed an app on your Mac and it asks you to enter the path of your file.
Regardless of why you want to reveal the path of a file, there are several ways to do so on your machine. MacOS comes built with a number of options to help you view and even copy the full path of any file saved on your machine.
If that’s not easy enough for you, you can even create your own Automator service that copies the path of your selected file in a single click.
Reveal File Paths Using The Info Box
If you have been using a Mac for some time, you may have likely seen the Get Info option that appears when you right-click on a file.
This option opens a box where all the information regarding your file is shown. This information includes the file name, file type, file size, and the most important one – file path.
To see it for yourself, open a Finder window, right-click on any of your files, and select Get Info.
On the following screen, look for the label that says Where and you will see the full path of your selected file on your Mac. It shows what folders and nested-folders your file is located in.
Whileit works great to help you find your file’s path, it does not letyou copy the file path as plain text if that is what you wanted todo. You may want to check out some of the other methods mentionedbelow if you want to copy the path of a file to your clipboard.
Copy File Paths From The Context Menu
The context menu on your Mac is a really powerful tool as it lets you do much more with your files than just letting you rename or delete your files.
One of the useful and hidden options in your context menu lets you directly copy the path of a file to your clipboard.
Since it’s hidden by default, it won’t appear when you right-click on a file on your Mac. However, unhiding the option is pretty easy and all it takes is pressing and holding down the Option key. This will make the option visible in your context menu.
Touse the option, right-click on a file in the Finder, hold down theOption key on your keyboard, and you’ll see the Copy“file-name.ext” as Pathname option. Click on it to copy yourfile’s path.
Itwill have copied the path of your selected file as plain text to yourclipboard.
Use Finder To View File Paths
You might think if Finder is a file management app, then why doesn’t it offer the feature to copy file paths? Unfortunately, the current version of the Finder doesn’t have an already-visible option to copy file paths.
However, that doesn’t mean there really is no way to view your file paths using the Finder. There is indeed a feature – not built for revealing file paths – but helps you view your file paths on your machine.
When the dialog box opens, drag and drop a file onto the input field and it will be filled with your file’s path. You may then copy the path to your clipboard using Command + C.
View File Paths UsingTerminal
Many users may think that the Terminal app on your Mac is only for programmers or for people who love coding. Although that’s true and the app does allow you to execute various commands, it can be used for basic tasks like copying file paths as well.
Theapp does help reveal file paths and it is pretty easy to do it.Fire-up the app on your Mac and drag and drop a file onto its window.The full path of the selected file will appear in your Terminalwindow.
It’salso useful when you are writing a command and you need to type thefull path of a file. Instead of typing, you can drag and drop thefile and it will fill-in the required input for you.
Create An Automator Service To Copy File Paths
Ifyou use a version of macOS that doesn’t offer the option to copyfile paths from the context menu, you can add the option to the menuyourself using an Automator service. An Automator service is auser-defined set of tasks that are performed when the service isinvoked.
History Of Mac Os X
That may sound too programmatic but doing so in practice isn’t that difficult. In fact, all it requires you to do is drag and drop an action from here to there and you have your service ready with Automator.
Launch the Automator app and select Service followed by Choose. It will let you create a custom service on your machine.
Configure the options at the top of the main panel as the following:
Search for the action named Copy to Clipboard in the left panel and drag and drop it onto the main panel.
Your service is ready and it’s time to save it. Click on File at the top and select Save. Enter a name for the service – this is what’s going to appear when you right-click on a file – and hit Save.
You’re now ready to copy file paths using the context menu on your Mac. Find the file you want to copy the path for, right-click on the file, and select Services followed by your service name.
The full file path will be copied to your clipboard in plain text formatting.
Bonus Tip: Assign a Keyboard Shortcut To The Automator Service
If you would like to make it even easier to copy file paths, you can assign a keyboard shortcut to your custom Automator service. So when you press this key combo, the path of the selected file will be automatically copied to your clipboard.
To do it, head to System Preferences > Keyboard > Shortcuts > Services, find your service in the list, and give it your chosen keyboard shortcut.
The shell path for a user in macOS or OSX is a set of locations in the filing system whereby the user has permissions to use certain applications, commands and programs without the need to specify the full path to that command or program in the Terminal. This will work in macOS Mojave, Sierra and all older OSX operating systems; El Capitan, Yosemite, Mavericks and Lion.
So instead of running something like this, with a path to the command:
You can just type the command, regardless of where you are in the filing system:
Your shell path is a bunch of absolute paths of the filing system separated by colons :
You can find out whats in your path by launching Terminal in Applications/Utilities and entering:
And the result should be like this…
So this is stating that you can run Unix style applications or commands located in 5 default locations of a certain path in the filing system:
/usr/bin
/bin
/usr/sbin
/sbin
/usr/local/bin
These directories are not visible by default in the filing system but you can make them visible.
Adding a Temporary Location
You can add extra locations to your path, in the mysql example above it’s location /usr/local/mysql/bin which is not in the default path, you can add it in Terminal like so:
So here I have copied my existing path and added the new location on the end. Test it by running echo $PATH again in the Terminal.
One of the disadvantages of this is that the new location will only be honored for that particular Terminal session, when a new Terminal window is launched it will have the original default path again.
Adding in a Permanent Location
To make the new pathstick permanently you need to create a .bash_profile file in your home directory and set the path there. This file control various Terminal environment preferences including the path.
Move into home directory
Create the .bash_profile file with a command line editor called nano
Add in the above line which declares the new location /usr/local/mysql/bin as well as the original path declared as $PATH.
Save the file in nano by clicking ‘control’ +’o’ and confirming the name of the file is .bash_profile by hitting return. And the ‘control’+’x’ to exit nano

So now when the Terminal is relaunched or a new window made and you check the the path by
You will get the new path at the front followed by the default path locations, all the time Java 6 for mac os x mavericks.
Rearranging the default $PATH
If you needed to rearrange the paths in the default $PATH variable, you can just do that and leave off $PATH.
Apple Mac Os X
So lets say you want /use/local/bin at the beginning to take precedence you can add the default path like so inside .bash_profile
