How to Upgrade macOS
There are two ways to upgrade macOS: directly in Mac App Store, or upgrade using an USB device.
No matter which way you choose, always remember to back up your data before performing an upgrade.
Time Machine Backup
Apple has its own official backup tool: Time Machine. This feature was released in OS X 10.5 Leopard. If you have never backed up, let me tell you how important it is.
Time Machine can connect to your Mac and any external hard drive via USB, FireWire or Thunderbolt port. Back up everything on your Mac directly to your hard drive, in case the Mac cannot upgrade properly.
It also supports Apple’s Time Capsule and backup disks connected over a network as long as the disks support AFPS. As long as the disk is available to your Mac, you can use it for Time Machine backups.
When enabled, Apple’s Time Machine will periodically transfer all files and store data on an inserted external hard drive or on a Time Capsule connected to the network.
You can choose hourly, daily or weekly backup to store your data on the external hard drive. When the external device is full, Time Machine will delete the oldest backup and replace it with the newer version.
Let’s check how to enable Time Machine backup on Mac devices.
1. Choose “System Preferences…” from the Mac menu.
2. Double-click the Time Machine icon.
3. Click “Select Backup Disk…” to select the disk you want to use as a Time Machine backup.
4. Select the “Back Up Automatically” check box so that your Mac will automatically back up data to your chosen disk.
If you want to restore files from Time Machine, make sure your Mac is running. Click “Enter Time Machine”, find the previous file or folder, and then click “Restore.”

1. Direct Upgrade in Mac App Store
Generally, you can upgrade your system directly in the Mac App Store by clicking “Check for Updates” or click the following link to download macOS High Sierra:
If you use a Beta version, you still need to click the link above to download the system, or go to the developer’s website for download information.
If you want to choose “USB clean upgrade”, check the detailed information below.
2. Upgrade using USB device
i. USB Preparation
Before formatting your current operating system, download macOS High Sierra from the Mac App Store first. You will need a copy of macOS High Sierra to perform a clean installation later. If you want to upgrade to this version, it is possible as long as your current operating system version is lower than macOS High Sierra.
Natively, look for “Disk Utility” in your application, select an external USB device with a capacity of 8 GB or larger, format it directly, and remember to choose the format “Mac OS Extended (Journaled)”. If it is a hard disk, it would be better to make a partition beforehand.
If you have already downloaded the macOS High Sierra package, do not click on the installation. Directly open the “terminal” program, which you can find in the application.
When typing the following text in the terminal, check the name of the formatted external USB device. If you do not name it “Untitled”, you need to change the command syntax of the path name: Volumes/Untitled. The names of external USB devices cannot contain spaces and are case sensitive.
sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install macOS High Sierra.app –nointeraction
Press “Enter” on your keyboard to execute the command. You will then be prompted to enter the administrator password. It will start the process after the operation, which can take a long time, depending on the transfer speed of the external USB device. When done, the terminal window will report “Done.”
ii. USB Upgrade Installation
a. Click the Apple icon .
b. Choose “Restart…” from the drop-down menu.
c. Press and hold “Command+R” when you hear a startup ring (or when the screen on your newer Mac device turns black), and hold down the keys until your computer restarts.
d. Open “Disk Utility”, choose your startup disk, and then click “Erase”.
e. Phpstorm 9 0 2 download free. Select “Mac OS Extended (Journaled)” from the list of volume formats and start formatting.

g. When the installation window appears, click “Continue” again.
h. Agree to the software terms and conditions. Choose your hard drive.
i. Click “Install” and wait until the upgrade is done.
How to Keep Your Mac Always Clean
If you have done a complete installation of macOS, you must be enjoying the completely new macOS now. I believe you also want to keep your Mac clean. Let’s say someday your Mac has a lot of junk files and duplicate photos. There are also probably many apps you have never used and don’t need them anymore. I must tell you there is a savior for your Mac! Its name is Cleaner One Pro. It’s really great to have such a system optimizing tool. With its “Junk Files” feature, it not only cleans temporary files including logs, mail caches, iTunes and iOS temporary files, and empties trash for the current user, but also detects remaining files after deleting apps.
It also has a function called “Duplicate Files”, which can find duplicate files on your Mac through fast and accurate scanning techniques covering your entire home folder. Duplicates are selected not only by the file name but also by their contents. Files are shown in detailed previews. It can further help you decide which copy to delete by presenting the “Auto Select” button.
Duplicates can be sorted by file type and listed in their full route for you to track. You can decide which way to clean these files; either by sending them to trash or deleting them permanently.
You probably also need an intelligent app uninstaller. Don’t worry, Cleaner One Pro has this function. It can auto-clean leftovers of deleted apps and manage all the applications installed on your Mac easily. When you remove an app you don’t need anymore, it can get rid of all the associated files of the uninstalled app as well. It will also notify you of new updates to installed apps.
Apple is preparing to issue Mac OS X Lion upgrade in the coming month, July. The update was announced on OCT 2010 and since then developers were allowed to download beta versions. I’ve downloaded Mac OS X Lion 10.7 preview 3 as a DMG file and upgraded my existing Snow Leopard installation with it. While announcing iOS 5 Apple CEO mentioned that they will list Lion to the Mac app store, instead of providing DVD disc for backup. Therefore, to do a new OS X Lion installation, we first need to install the Snow Leopard and then upgrade to Lion from the app store.
Mac OS X Lion 10.7 in action:
Old versions of Snow Leopard will not have Mac app store in the package. Run Apple software update and upgrade OS to 10.6.8 in case if you are installing Leopard from an aged disc. After that you will find the app store icon in the dock. Sign in with your Apple ID and password and find the Lion update (around 3.7GB) from the catalog. You can buy and download OS X Lion 10.7 for $30 if you have a credit card or a PayPal account on file. Then execute the DMG file (It’s Lion.app when you get it from store) and wait for the installer to finish everything.
OS X 10.7 will not change any user settings on Snow Leopard partition when it is upgraded. So full backup is not a must thing*. But if you want to do a fresh Lion installation here is how to do that.
