Format Ssd For Mac Os High Sierra
Apple introduced a new filesystem in macOS High Sierra, so naturally you may be wondering how Carbon Copy Cloner deals with this and how this new change might affect your backups. You might even be wondering, 'What's a filesystem?', so we'll start with that, and gradually move into more technical details.
At last my MacBook Pro 7.1 mid 2010 is creating a bootable external drive with “Install macOS High Sierra” from the App Store, so that I can upgrade the internal disk to WD Blue 250GB SSD. May 08, 2020 macOS Mojave and Catalina: The installer converts from Mac OS Extended to APFS. MacOS High Sierra: The installer converts from Mac OS Extended to APFS only if the volume is on an SSD or another all-flash storage device. Fusion Drives and traditional hard disk drives (HDDs) aren't converted. Sep 27, 2017 Let the installer complete, when finished you will be informed that the process has completed; Once you have created the USB boot installer drive for macOS High Sierra, you can either launch it immediately to install macOS High Sierra on the current Mac, reboot and startup from the USB installer drive, or eject it and use it on another Mac. When you have the need to format a hard drive under macOS 10.13 High Sierra, it typically requires the use of third-party hard drive format software like Disk Utility.In this article, we will introduce you a few tools you can use for formatting hard drive under macOS 10.13 High Sierra.
Jan 09, 2018 The High Sierra boots up on Samsung SSD a bit sluggishly in the first run. If I restart, the OS, it just freezes at some point. I tried to perform a clean install from the bootable usb, but the installation process was frozen after saying 'one minute left'.
What's a filesystem?
The file system is perhaps the most important piece of software on your Mac. It’s also one of the most transparent, at least when it’s working correctly. Every user and every application uses the file system. The file system keeps track of and organizes all of the files on the hard drive, and also determines which users and applications have access to those files. The file system also keeps track of how many files you have and how much space they consume. Every time you look for a file, open a file, move a file, save a file or delete a file, it's the filesystem that is fulfilling that action.
Why is Apple introducing a new filesystem?
Apple’s legacy file system, HFS+, has worked well for almost 20 years, and Apple has made consistent improvements to it over that time. For example, Apple added support for extended attributes, file system compression, file system journaling, and full-disk encryption. All of these new features were added to keep pace with new operating system features and to make the file system more reliable. But that file system was created initially for Mac OS 8, and was designed for platter-based hard drives. Storage technology has changed a lot over the last 20 years, and modifying HFS+ to keep pace with those changes has proven increasingly difficult. To meet the challenges of new OSes and new storage technology, Apple introduced the Apple File System, or 'APFS' in High Sierra.
When I upgrade my Mac to High Sierra (or later), will my startup disk be converted to APFS?
When you upgrade to macOS High Sierra, systems with all flash storage configurations are converted automatically. Systems with hard disk drives (HDD) and Fusion drives won't be converted to APFS on macOS High Sierra. When you upgrade to Mojave, HDD and Fusion volumes are also converted to APFS. You can't opt-out of the transition to APFS.
Can CCC make a bootable backup of an APFS volume?
Yes. Both CCC 4 and CCC 5 can make bootable backups of APFS-formatted startup disks, however there is a limited amount of support for APFS in CCC 4. CCC 4 can make a bootable backup from an APFS-formatted volume to an HFS+ formatted volume. CCC 5 can make a bootable backup from an APFS-formatted volume to an HFS+ formatted volume or to an APFS-formatted volume. CCC 5 also supports APFS encryption (e.g. CCC 5 can unlock and mount APFS-encrypted volumes during a backup task). Naturally any additional support that we can provide for APFS will be made within CCC 5; new features and functionality will not be added to CCC 4.
Can CCC make a bootable APFS volume? That is, can the destination be an APFS volume?
Yes. When cloning macOS 10.13 or later to an APFS-formatted volume using Carbon Copy Cloner 5, we expect the destination volume to be bootable.
If I first upgrade to High Sierra on an HDD, and then clone to an SSD, will the SSD be converted to APFS?
If you're running macOS High Sierra or Mojave, then neither the HDD nor the SSD will be automatically converted to APFS. You can choose, however, to erase the SSD as APFS prior to cloning to it. Both APFS and HFS are valid destination formats when using Carbon Copy Cloner 5 on High Sierra and Mojave. When making a backup of a macOS Catalina system volume, CCC will automatically convert the destination volume from HFS+ to APFS, but only after your explicit approval of the action.
If the OS upgrade converted my startup disk to APFS, what do I need to do to my backup disk? Do I have to erase it as APFS?
You don't need to do anything at all to your backup disk after upgrading to macOS High Sierra or Mojave (and again, on macOS Catalina, CCC will automatically convert the destination to APFS, so you still don't have to do anything to the destination volume). Having an HFS+ backup of an APFS-formatted High Sierra or Mojave startup volume is acceptable; that will function just fine for any future restores, even to an APFS-formatted volume. If your backup disk is an SSD, or if you were planning to erase the destination anyway, we do recommend that you erase it as APFS.
I'm running Mojave — can I erase my HDD destination as APFS? Are there any advantages to using APFS on the destination?
If you were planning to erase your destination volume anyway, we recommend that you format the volume as APFS. While enumeration performance of APFS on a rotational disk is still significantly worse than HFS+ on the same hardware, there are some other advantages to choosing APFS rather than HFS+. For example, an APFS destination can store snapshots from which you can do point-in-time restores. APFS volumes also support sparse files, and you're less likely to run into name comparison problems (e.g. when files on the source APFS volume have Unicode characters like 'é') when backing up to an APFS-formatted volume. You also cannot boot a T2 Mac from an HFS+ encrypted volume, so if you have a T2 Mac and encryption of the backup is required, you must choose APFS.
Can I use CCC to clone an APFS startup disk to another Mac?
The macOS installer applies a firmware upgrade to your Mac when you install the macOS upgrade. This firmware upgrade cannot be made part of the cloning process. Only the macOS Installer can upgrade a Macintosh to support APFS. If you attempt to clone an APFS volume to a Macintosh that has not yet received the firmware upgrade from the macOS Installer, that Macintosh will not be able to boot from the APFS volume. Once your Mac has received the firmware upgrade via the macOS Installer, your Mac can boot from a CCC bootable backup on an APFS volume. Note, however, that every major MacOS upgrade may require a new firmware upgrade to allow use of the newer operating system.
Note that this is also applicable to a Macintosh running in Target Disk Mode. If you upgrade one Mac to High Sierra (or later) via the Installer, you cannot boot a second Mac into Target Disk Mode, attach it to the first, then clone High Sierra (or later) to the Mac in Target Disk Mode. The required firmware upgrade cannot be applied to the Mac that is booted in Target Disk Mode, you must run the macOS Installer on that second Mac. Once the second Mac has received the firmware upgrade via the macOS Installer, you can clone the first Mac to the second Mac booted in Target Disk Mode.
Does CCC support encrypted APFS volumes?
Yes, CCC 5 can clone to and from encrypted APFS volumes (aka FileVault encryption). Note that CCC doesn't play any role in the encryption process – encryption is a function of the volume, not of the tool that's writing a file. If you enable FileVault on your startup disk, then the files on your startup disk will be encrypted. Those files are decrypted on-the-fly by the filesystem when they're opened by an application. Likewise, if you enable FileVault on the destination volume (e.g. via the Security Preference Pane while booted from the backup), then the files on the destination will be encrypted. CCC doesn't have to encrypt those files, they're encrypted on-the-fly by the filesystem as the bits are written to disk.
I heard that APFS has a 'cloning' feature. Is that the same as what CCC is doing?
No, the cloning functionality within APFS is completely unrelated to the cloning that CCC performs.
APFS cloning allows the user to instantly create copies of files on the same volume without consuming extra storage space. When cloning a file, the file system doesn’t create copies of the data, rather it creates a second reference to the file that can be modified independently of the first file. The two files will share storage on the disk for portions of the files that remain identical, but changes to either file will be written to different parts of the disk. APFS file cloning only works when you make copies of a file on the same volume (e.g. duplicate a file or folder in the Finder). CCC is typically copying files between volumes, so APFS cloning isn't applicable for that kind of task.
The important take-away is that APFS file cloning can save you space on your startup disk, but CCC cloning can save your data if your source disk fails. They serve completely different purposes; APFS file cloning is not at all related to making backups.
Why doesn't the disk usage on my backup disk match the disk usage on the source disk?
CCC's global exclusions as well as the SafetyNet feature have traditionally led to legitimate differences in disk usage in the past. The aforementioned APFS file cloning feature, however, adds a new dimension to this concern. While APFS file cloning saves space on your source volume, those space savings can't be consistently applied when copying your files to another volume (because Apple doesn't offer a way for us to determine that one file is a clone of another). Making matters worse, Finder does not accurately represent the true disk usage of your files. Finder doesn't take into consideration whether one file is a clone of another (again, because Apple doesn't provide a way to make that assessment), so it sums up the total size of each file and folder, presenting a total value that is possibly astronomically higher than the capacity of the disk.
If you convert your Mac's disk to APFS, understand that the disk usage on your source and destination may never add up, and therefore may not be a reliable measure for comparing the source and destination.

- Prepping your Mac for Sale
It is that time again. Time to decide whether to keep or replace your Mac laptop or desktop computer. If you are reading this article, chances are you've already come to the decision to replace your Mac with the newes model (or maybe you just got a new Mac as a present!), and you're thinking about selling your old one.
The first thing you should do before hitting the streets to sell your old Mac is clear it of any and all personal data. You don't want to accidentally sell your computer to a stranger when you are still logged into iCloud.
The next step is to reinstall the Mac's operating system so that the new owner can get started without having to figure out how to start up in recovering mode. Believe me, that can be a pain.
If you're going through the process of erasing your old Mac and reinstalling the operating system, we've got some common troubleshooting tips to help you out. Don't forget to follow the additional steps if you're selling a MacBook with Touch ID.
Format Ssd For Mac Os High Sierra 10 13 6
Clean the Mac of your personal data before erasing it
If you're about to sell your old Mac, the one thing you don't want to do is to give away the data you've been storing on it all these years. It's a security and privacy thing for you, but it's also important for the buyer. If you leave behind anything that needs to be logged into with a password, that buyer is going to have to track you down and get your password in order to change ownership. A completely fresh-from-scratch Mac is the best way to do this.
Step 1: Back up your Mac
If you already have your new Mac on hand, you can transfer all of your data from your old Mac or use an older Time Machine backup. If you don't have your new Mac yet, well .. then you probably shouldn't be selling your old one yet. But, if you really don't think you'll need your old computer before getting your new one, just make sure to back up your data so that nothing happens to it before you get what you need onto your new Mac.
Step 2: Sign out of everything
The software you have on your Mac is licensed to you, which means it doesn't get transferred to the new owner of your computer (except the operating system). In order to avoid complications with the new owner attempting to download and install software that is licensed by you, make sure to sign out of everything your personal information is connected to.

- Click on Sign Out.
- Click Remove data from this Mac when prompted.
Step 3: Unpair your Bluetooth devices
If you're keeping your Bluetooth devices, you don't want to leave them paired to a Mac that you're getting rid of. It isn't really that important of a step, but if you sell your old Mac to, say, a roommate or someone living in the same house as you, you may experience accidentally connecting back to it.
- Click on the Apple icon in the upper-left corner of your Mac's screen.
- Click System Preferences from the drop-down menu.
- Click on Bluetooth.
- Hover over the device you want to unpair.
- Click on the X next to the device.
Note: If you're unpairing a keyboard, trackpad, or mouse on a desktop Mac, be sure to have a wired one plugged in or you won't be able to type or use a curser and you'll have to repair it all again.
Step 4: Erase your hard drive
Once your data is backed up and you've signed out of everything that might connect your old Mac to your personal information, you can erase everything on it by reformatting the hard drive.
- Restart your Mac.
- While the startup disc is waking up, hold down the Command+R keys simultaneously. Your Mac will boot into macOS Recover.
- Select Disk Utility.
Click on Continue.

- Click on View.
- Click on Show all Devices.
- Find your Startup disk (it should be named 'Machintosh HD' unless you renamed it) in the sidebar.
- Select the data disk under the startup disk.
- Click Edit.
- Click Delete APFS Volume from the menu bar or click the Remove button in the disk utility bar.
- Confirm by clicking Delete when prompted.
Repeat this process for all data disks under your startup disk. Do not use Delete Volume Group. Once you've deleted all of your data drives, you'll move on to erasing your startup disk.
- Select your Startup Disk (it should be named 'Machintosh HD' unless you renamed it) in the sidebar.
- Click the Erase button at the top of the Disk Utility window.
- If your Mac is using HFS+, select Mac OS Extended (Journaled) from the format list. If your Mac is using APFS, select APFS from the format list. See Troubleshooting for more information on which format to select.
- If Scheme is available, select GUID Partition Map.
Click Erase.

- Restart your Mac.
- While the startup disc is waking up, hold down the Command+R keys simultaneously. You're Mac will boot into macOS Recover.
- Click on Reinstall macOS (or Reinstall OS X where applicable) to reinstall the operating system that came with your Mac.
- Click on Continue.
- Select your hard drive ('Machintosh HD), when asked to select your disk.
Click on Install to install the latest operating system that was on your Mac. Your Mac will restart after the installation is complete.
- Make sure you don't close the lid on a MacBook or put your Mac to sleep during this reinstallation period, even if it takes a while. If the computer goes to sleep, it will stop the installation process from continuing and you'll have to start over. Your screen will go blank, show the restart Apple logo, and show a progress bar several different times.
- Hold down Command and Q after the installation is complete. Do not follow the setup instructions. Leave that part for the new owner.

Troubleshooting erasing your hard drive or reinstalling macOS
I've gotten a lot of very specific questions about issues some readers have with erasing or reinstalling macOS (usually reinstalling). Sometimes, the easiest way to fix issues with reinstalling macOS is to start by holding Shift+Option+Command+R which will put your Mac into an alternate version of Recovery Mode that allows you to install the original macOS that came with your Mac. From here, you can either keep that operating system and let the new owner update to their preferred macOS, or go through the macOS update process.
If, during the macOS reinstallation process, the installer doesn't see your disk or says you can't install the operating system on the disk, you may need to try erasing your hard drive again. Restart your Mac and hold down Command+R to bring up Recovery mode and repeat Step 4.
Since macOS changed to APFS, some readers have struggled with which format option to choose when erasing their disk. Here are some other possible troubleshooting issues from Apple's support document that may help you.
Are you formatting the disk that came built into your Mac?
If the built-in disk came APFS-formatted, don't change it to Mac OS Extended.
Are you about to install macOS High Sierra or later on the disk?
If you need to erase your disk before installing High Sierra or later for the first time on that disk, choose Mac OS Extended (Journaled). During installation, the macOS installer decides whether to automatically convert to APFS—without erasing your files:
- macOS Mojave and Catalina: The installer converts from Mac OS Extended to APFS.
- macOS High Sierra: The installer converts from Mac OS Extended to APFS only if the volume is on an SSD or another all-flash storage device. Fusion Drives and traditional hard disk drives (HDDs) aren't converted.
Are you preparing a Time Machine backup disk or bootable installer?
Choose Mac OS Extended (Journaled) for any disk that you plan to use with Time Machine or as a bootable installer.
Will you be using the disk with another Mac?
If the other Mac isn't using High Sierra or later, choose Mac OS Extended (Journaled). Earlier versions of macOS don't mount APFS-formatted volumes.
To learn which format is currently in use, use any of these methods:
- Select the volume in the Disk Utility sidebar, then check the information on the right. For more detail, choose File > Get Info from the Disk Utility menu bar.
- Open System Information and select Storage in the sidebar. The File System column on the right shows the format of each volume.
- Select the volume in the Finder, then choose File > Get Info from the menu bar. The Get Info window shows the Format of that volume.
