• What Are Correct Permission For Mac Os Sierra Hard Drive 2017

Every file and folder on a Mac OS X hard drive has a set of permissions —settings that determine which user(s) have access to each item, and exactly what that access is. For example, permissions. Jan 15, 2019 If you’ve noticed that your Mac isn't performing at its silky smooth best, disk permissions may be to blame. In this article, we’ll give you the lowdown on what permissions are and show you how to go about fixing the ones that have gone rogue with the help of Disk Utility and CleanMyMac. Apr 06, 2020 According to Apple, manual disk permission repair isn’t necessary anymore. MacOS Catalina, Mojave, High Sierra, and Sierra (and Mac OS X El Capitan) repair file permissions automatically during software updates. Improved file integrity starting with El Capitan and expanded in macOS Sierra, apparently makes manual disk permissions obsolete. Sep 06, 2019 Choose a new name for your Mac’s hard drive. Change the format to Mac OS Extended (Journaled). When the process is complete, press command+Q to close Disk Utility. Make sure to select the parent hard disk in the sidebar. Install macOS using Internet Recovery Mode. USB Stick / External Hard Drive: If you are planning to use a USB for downloading the bootable version of the installer, make sure that it is 8GB in size or larger than that. In the case of Sierra, 12GB is recommended as the minimum requirement.

The macOS Sierra is a wonderful operating system - and easily the best for all Apple computers and laptops. If you have a Mac, then you probably cannot wait to get your hands on the Sierra - provided your system supports it. However, even if your Mac does support Sierra, there may be a few reasons as to why you may not be able to install it on your hard disk.

For starters, it takes around 8GB of storage space. While that is the minimum recommended by Apple, you will probably need a bit more to make use of it. In addition to that, if you are using an older Mac, then you will still face a few issues while running Sierra. You also have to backup the entire system before installing macOS Sierra, which is a must-do step in any update. For those who have a lot of data on their Macs, this can be a very lengthy procedure.

However, there is a solution to all of that. You can simply go ahead and install the macOS Sierra on an external hard drive, and then boot your Mac from that!

The Prerequisites

There is no doubt about the fact that you will save a lot of trouble and hassle if you install the macOS Sierra on an external drive. It will even let you use the same hard drive with multiple Macs, without updating to Sierra on each of those. However, to begin with this, you will need an external hard drive. Since Apple only requires you to have a little over 8 GB of free space, any hard drive, even one with 128 GB, will do just fine. For better performance, it is recommended that it be an SSD.

You will also have to download macOS Sierra from the Mac App Store. To do that, just open the App Store on your Mac, and search for macOS Sierra. You can also download macOS Sierra by directly clicking on the link from your Mac. If your Mac is compatible, then the download option will appear. Click on it, and the download will begin.

The download size is around 5GB, and the total time may vary depending on your internet connection as well as Apple’s servers.

Once you have a hard drive, you can go ahead and follow the simple steps to install and use macOS Sierra from your external drive.

Part 1. Installing macOS Sierra on the external drive

1. Preparing the hard drive for the installation

Before you install macOS Sierra on the hard drive, you will need to clean the external device. Ensure that there is no important data on your hard drive. Then plug it into your Mac, go to Finder and select Applications.

From Applications, go to Utilities and from there, find and double click on Disk Utility. In the Disk Utility tab, select the external hard drive that is connected to the Mac, and then click on Erase at the top.

Now rename it to something like sierra that you will remember, choose 'Mac OS Extended (Journaled)' in the format and then click on Erase. Once the process completes, click on Done, and you are ready to begin installation.

2. Creating the bootable drive

Once your hard drive is formatted, you will need to turn it into a bootable drive. Before you begin this, you will require the Administrator access on your Mac.

Step 1 Go to Finder to open the window, and from the left side, select Applications.

Step 2 From the applications Window, find and click Utilities, and from there, go to Terminal.

Step 3 Now, remember the name that you set for formatting your external drive (i.e. sierra). In case you named it something other than sierra, then make the appropriate changes in the following text. Once you are in the terminal, enter the following text, ensuring to use your drive’s name wherever Volumes/sierra is written.

sudo /Applications/Install macOS Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/sierra --applicationpath /Applications/Install macOS Sierra.app –nointeraction

Step 4 When you tap enter, you will be asked the password for the administrator account. As you type the password, no text will be there in the terminal window. Depending on the drive, this process could take a while. Once the window reports ‘Done’, you can close the drive.

Part 2. Using macOS Sierra with the Bootable Hard Drive

Once the above step completes, your external hard drive will be ready to run macOS sierra on any compatible Mac. First, you have to turn off the Mac on which you want to run Sierra from the bootable drive. Then, before switching it on, connect the drive through the Mac’s USB Port.

Then turn on your Mac, and as soon as you hear the startup sound, press the Option key and keep it pressed. Within a few seconds, you will get a screen that asks you to select the appropriate hard drive for booting from. In this screen, select the one on which you have installed macOS Sierra, and you will soon have your Mac running Sierra!

Thus, as you follow these simple steps, you will have configured the macOS Sierra to run from an external hard drive. You do not have to worry about how much free space there is in your Mac, or anything else of the sort. Through this approach, you can run macOS Sierra on any compatible Mac without having to separately download and install it on either one. In addition to that, since there are no backups of the mac’s hard disk required, the process will involve comparatively less hassle.

Any changes or files that you make can be stored on your Mac as well, so you do not have to worry about where your data is. This can be a great way to have the same OS on your personal as well as work Macs. Thus, now, you do not have to bother about freeing up your Mac’s drives or separately downloading it for every PC in the house- just configure it once on an external hard drive, and everything else is taken care of!

One of the old Mac OS X utilities, Disk Utility, has received a makeover in macOS Sierra. The updated app now presents a streamlined appearance while retaining all of its former functionality, and it’s still useful for verifying or repairing disks. This can be useful if you’re running into odd issues with a Mac, so we’ll take a look at the process of verifying and repairing disks with macOS Sierra’s Disk Utility.

Some of the issues you might encounter that indicate a disk that might need repair:

• Multiple apps quit unexpectedly
• A file is corrupted
• An external device doesn’t work properly
• Your Mac refuses to start up

Verifying Disks
Verifying a disk subjects it to a series of checks, all of which are done through a process called “Live Verification”. This means that Disk Utility can check the status of a disk, its catalog file, multi-linked files, catalog hierarchy and more the Mac needing to be started up with another disk drive. It does this by “freezing” the volume, so while you’re running the verification tests you may find that your Mac becomes slow or unresponsive.

To verify a disk, simply launch Disk Utility (found in Applications > Utilities), click on the drive volume you wish to check, then click on the First Aid button in the Disk Utility toolbar. Disk Utility responds by stating what it’s about to do:

Click the blue Run button to begin the process of verifying the disk. Disk Utility informs you of what’s about to happen, specifically noting that apps will become unresponsive during the tests.

Click the blue Continue button, and Disk Utility begins to perform its battery of tests on the hard drive. The process usually runs quickly, taking only a few minutes to verify a large (2 TB) boot drive. You’ll get a notification that the First Aid process is complete (see image below), with either a green check mark indicating that everything appears to be OK or a red X indicating that there are some issues that need to be repaired. To repair a disk, it’s necessary to boot from another drive, then run Disk Utility again. We’ll cover that in the next section of this post.

Note that the Live Verification process only works on volumes that have been formatted as “Mac OS Extended (Journaled)”. If you run First Aid on a volume that is not journaled, Disk Utility responds with an error message saying “ERROR: could not freeze volume (Operation not supported). In addition, you may not be able to interrupt the Live Verification through First Aid, so it’s best to let it continue to run until completed. Finally, an alert message that says “Incorrect size for file temp” is no cause for alarm.

Repairing a Disk
If First Aid and the Live Verification process indicate that repairs are required on a volume, it’s time to boot from another disk drive and then run Disk Utility again. Fortunately for Mac users, there’s a built-in “boot disk” in the guise of the Recovery Partition.

Mac Os Sierra Download

To boot from the Recovery Partition, restart your Mac and hold down the Option key. When the Mac restarts, you are greeted by icons for all of the available drives. In the example below, there’s a Sierra drive, a Windows drive (Boot Camp), and a drive designated “Recovery-10.12”. macOS Sierra is also known as macOS 10.12, so this is the Recovery Partition for our Sierra boot drive.

Use your mouse, trackpad, or keyboard arrow keys to highlight the “Recovery-10.12” drive, then press Return. Once the system has booted, four macOS Utilities are listed, one of which is Disk Utility (see image below). Click Disk Utility to select it, then click the Continue button. The familiar Disk Utility window appears. Click on the drive requiring repairs, then click First Aid again. As before, Disk Utility will take the volume through the Live Verification process. When it finds errors on that volume, it can now repair them since you’ve booted from another disk.
