Oct 02, 2017 After you have made the High Sierra bootable installer, you can proceed with the next step of formatting the hard drive. 3: Format & Erase the Mac Hard Drive. With the MacOS High Sierra boot drive connected to the Mac, reboot the computer and hold down the OPTION / ALT key until you see the Startup Manager screen. At the boot drive selection. On a Mac, you can add password to lock your folders to protect the personal files and privacy. The built-in disk utility of macOS sierra system makes it easy to set protection password for a folder. The built-in disk utility of macOS sierra system makes it easy to set protection password for a folder. Oct 12, 2016 The method we are going to outline here will reinstall macOS system software versioned as High Sierra or Sierra without formatting or erasing the Mac, instead only macOS Sierra 10.12 system software will be reinstalled (or macOS High Sierra 10.13, whichever is applicable). The obvious advantage to this approach is that it aims to preserve user.
It’s almost become a tradition; one that we wish we didn’t have to put up with. It seems with each new version of the Mac operating system, there are some features that just don’t seem to work the way they used to. The tradition lives on with macOS High Sierra, so we’re gathering a list of what High Sierra broke and how to fix it (when you can).
Drive Encryption Can Change Formatting Encrypting an entire drive to add a level of security has been an easy task in the Mac OS ever since FileVault 2 was released as part of OS X Lion. Full disk encryption has been a boon for Mac users who worry about their personal data being easily accessible on their Macs or external drives. This is especially true for portable Mac users, who need to worry about their Macs being lost or stolen.
Jun 12, 2019 2.5 Make Mac OS Virtual Machine Boot From Virtual Hard Disk And Continue Install. Shut down the mac os virtual machine by click the virtual machine’s close button, and select Power off the machine radio button, then click OK.; Right click the mac os virtual machine, then click Settings menu item in the popup menu list.; Click Storage — MoJave.iso (or high-sierra.iso ) — Optical Drive. Jul 08, 2012 So, to reset that partition (and fix that locked issue) click on the hard drive (the line with manufacturer's info), then click the Partition tab. Click the drop down to change partition type to 1 Partition, give it a name, if you like, and click the Apply button.
macOS High Sierra continues to support full disk encryption, but Mike Bombich, who created Carbon Copy Cloner, has verified a bug in High Sierra that will cause an external drive to have its format changed from HFS+ to APFS when the drive is encrypted in High Sierra.
Enabling encryption on a drive should not alter the underlying drive format. If the drive was HFS+ (Hierarchical File System) before you chose to encrypt it, it should remain an HFS+ drive afterwards. The same is true for APFS (Apple File System) formatted drives; choosing the encryption option shouldn’t change the APFS format of the drive.

(Encrypting an external drive can lead to the drive being converted to an APFS volume.)
Under certain conditions, encrypting a drive will modify the format to APFS without the user being aware of the changes.
The specific conditions are:
Must be an external drive
Must not have a Mac operating system installed on the drive
If these two conditions are met, and you select the option to encrypt the drive, by right-clicking the drive icon and selecting Encrypt from the popup menu, the drive will be converted to APFS format and then encrypted.
Even though the drive has been converted to APFS and encrypted, it will continue to work just fine with your Mac running macOS High Sierra. The problem comes about should you ever connect the drive to a Mac running an earlier version of the Mac operating system, or if you boot your Mac to an earlier version of the OS. In either case, the external drive won’t be recognizable by the older operating system.
Our recommendation is not to encrypt your external drive, unless converting to APFS is acceptable to you, and you have no plans to use the drive with earlier versions of the Mac operating system.
Being Logged Out Randomly If you find yourself occasionally being logged out of your Mac after you upgraded to macOS High Sierra, you can stop worrying; your Mac isn’t possessed. Instead, the upgrade process may have enabled two security options that you may not have been using before.
(If you’re being logged out from time to time, it may be because the Log out option, shown above, has been set during the installation of macOS High Sierra.)
To correct the phantom logouts, launch System Preferences, either by clicking on its Dock icon, or by selecting System Preferences from the Apple menu.
In the System Preferences window, select the Security & Privacy preference pane.
From the Security & Privacy preference pane, click the Lock icon and enter your administrator credentials. Once the padlock is unlocked, click on the Advanced button.
Either remove the checkmark from “Log out after xx minutes of inactivity” or set the time frame to a longer period to meet your needs. Click the OK button when done.
The second security issue that may be causing the problem is also located in the Security & Privacy preference pane. Select the General tab.
The item: “Require password xx minutes after sleep or screen saver begins” may also be checked. You can remove the checkmark, or modify the amount of time that needs to pass before the screen saver kicks in to better fit your needs. My own preference is to leave this security feature in place, and just adjust the time as needed.
While you’re at it, you may want to jump over to the Desktop & Screen Saver preference pane to adjust the time for when the screen saver starts up.
(Be sure to check the General tab of the Security & Privacy preferences for password requirements to wake from sleep. These may have also been changed during the install.)
Select the Screen Saver tab, then use the Start after: dropdown menu to select how much inactive time needs to elapse before the screen saver starts
High Sierra Battery Life is Poor Another issue that seems to be common is portable Mac battery life being adversely affected after an upgrade to High Sierra. So far, it seems that macOS High Sierra isn’t the culprit; instead, there are a few apps that may need to be updated to make better use of the battery.
Macos High Sierra Disk Locked
Launch Activity Monitor, located at /Applications/ Utilities.
In the Activity Monitor window, select the Energy tab.
(Activity Monitor’s Energy tab can help you find apps gulping down the power from your battery.)
In the resulting display, look for apps that are marked as preventing sleep, or are listed as having a high energy impact. Contact the app developer to see if there are updates available for the app to make it perform better with macOS High Sierra.
Unable to Wake From Sleep I’m not sure what it is about sleep, but the Mac seems to always have issues with sleep after a system upgrade. There have been reports of Macs not being able to wake from sleep after upgrading to High Sierra.
Unrelated, but with the same solution, is a flickering of the display, especially when the Safari browser is open.
High Sierra Os
You can fix both issues by resetting the NVRAM and then resetting the SMC.
You can find detailed instructions on how to perform these resets in the article:
How to Reset NVRAM, PRAM, SMC on your Mac.
Office 2011 Crashes If you’re using Office 2011 for the Mac with macOS High Sierra, you’re not having any issues, you’re having occasional crashes, or Office simply refuses to launch at all.
That about covers most of the possibilities. The problem is Microsoft decided not to support Office 11 under macOS High Sierra, meaning they haven’t tested the apps nor are they going to offer any updates to correct any issues. Essentially, Office 2011 is on its own. If it works for you, wonderful, but if you have any issues, it may be time to consider a replacement.
Of course, software apps do get old, and Office 11 has been around for a long time, in software years. If you have a specific need for Microsoft Office, the Office 2016 for Mac version works fine and is fully supported under macOS High Sierra.
If you just need a Word or Excel work-alike that you can use to share files with others, there are a few options available. If you have a suggestion that you know works with High Sierra, please leave a note in the Comments, below.
Mail Stops Notifying You of New Mail
Have you noticed that Mail is no longer alerting you of new incoming messages via the Notifications center? If you’re used to seeing a banner pop up in the top right corner of your Mac’s display with a brief description of a new piece of mail whenever new mail arrives, you may have noticed the banners stopped once you installed High Sierra.
This bug doesn’t seem to affect everyone, but it happens often enough that Apple should be able to fix the issue in a subsequent update of High Sierra.
But you don’t need to wait for Apple; you can fix the issue yourself by opening System Preferences and selecting Notifications.
Highlight Mail in the Notifications window sidebar, and then select None as the Mail alert style. Wait a moment, then set the notifications style back to Banners or Alerts, whichever you prefer.
Close the Notifications preference pane.
(The Notifications center may need its mail handling alert style reset to work properly after installing High Sierra.)
Launch Mail if it isn’t already running. Mail notifications should now work correctly.
Adobe Photoshop and Illustrator Issues Adobe Photoshop has a minor issue with High Sierra that prevents the Photoshop window from expanding to full screen whenever the Dock is shown.
Adobe has created a Photoshop plug-in file that can rectify the problem. You’ll find instructions on how to download and install the plug-in at the Adobe Help website.
Adobe Illustrator is experiencing some issues with High Sierra; specifically, the licensing system seems to be broken when the startup drive uses the APFS file system. The result is Illustrator may not launch, or there will be an error message about license problems.
Adobe recommends not upgrading to High Sierra, or not converting to the APFS file system at this time.
There’s an additional issue with Illustrator on macOS High Sierra that results in the wrong color settings being applied; specifically, Emulate Adobe Illustrator 6 becomes the default color setting and is applied to any document you open or new document you create.
The workaround is to manually change the color settings before working with any document.
Select Edit, Color Settings, and then choose the desired settings for the document.
Click OK.
Open the document you wish to work on.
You’ll need to repeat these steps each time you launch Illustrator, or before you open a document that uses a different color space.
Other High Sierra Problems and Fixes macOS High Sierra is still relatively new, and I suspect there will be quite a few additional issues that will crop up. If you encounter any problems with using High Sierra, please feel free to share with our readers by leaving a comment.

Reinstall from macOS Recovery
macOS Recovery makes it easy to reinstall the Mac operating system, even if you need to erase your startup disk first. All you need is a connection to the Internet. If a wireless network is available, you can choose it from the Wi-Fi menu , which is also available in macOS Recovery.
1. Start up from macOS Recovery
To start up from macOS Recovery, turn on your Mac and immediately press and hold one of the following sets of keys on your keyboard. Release the keys when you see an Apple logo, spinning globe, or other startup screen.
Command (⌘)-R
Reinstall the latest macOS that was installed on your Mac (recommended).
Option-⌘-R
Upgrade to the latest macOS that is compatible with your Mac.
Shift-Option-⌘-R
Reinstall the macOS that came with your Mac, or the closest version still available.
You might be prompted to enter a password, such as a firmware password or the password of a user who is an administrator of this Mac. Enter the requested password to continue.
When you see the utilities window, you have started up from macOS Recovery.
2. Decide whether to erase (format) your disk
You probably don't need to erase, unless you're selling, trading in, or giving away your Mac, or you have an issue that requires you to erase. If you need to erase before installing macOS, select Disk Utility from the Utilities window, then click Continue. Learn more about when and how to erase.
3. Install macOS
When you're ready to reinstall macOS, choose Reinstall macOS from the Utilities window. Then click Continue and follow the onscreen instructions. You will be asked to choose a disk on which to install.
If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
If the installer is for a different version of macOS than you expected, learn about macOS Recovery exceptions.
If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.
Download Mac Os High Sierra
Please allow installation to complete without putting your Mac to sleep or closing its lid. During installation, your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.
If your Mac restarts to a setup assistant, but you're selling, trading in, or giving away your Mac, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.
macOS Recovery exceptions
The version of macOS offered by macOS Recovery might vary in some cases:
If macOS Sierra 10.12.4 or later has never been installed on this Mac, Option-Command-R installs the macOS that came with your Mac, or the closest version still available. And Shift-Option-Command-R isn't available.
If you erased your entire disk instead of just the startup volume on that disk, macOS Recovery might offer only the macOS that came with your Mac, or the closest version still available. You can upgrade to a later version afterward.
If your Mac has the Apple T2 Security Chip and you never installed a macOS update, Option-Command-R installs the latest macOS that was installed on your Mac.
If you just had your Mac logic board replaced during a repair, macOS Recovery might offer only the latest macOS that is compatible with your Mac.
Mac Os High Sierra Drive Locked Mode
If you can't get macOS Recovery to offer the installer you want, you might be able to use one of the other ways to install macOS.
Other ways to install macOS
Mac Os High Sierra Features
You can also install macOS from the App Store or Software Update preferences. If you can't install macOS Catalina, you might be able to install an earlier macOS, such as macOS Mojave, High Sierra, Sierra, El Capitan, or Yosemite.
Or create a bootable installer disk, then use that disk to install macOS on your Mac or another Mac.
