Recovery Disk For Mac Os Sierra: Tips and Tricks for a Successful Recovery

The OS X Recovery Disk Assistant lets you create OS X Recovery on an external drive that has all of the same capabilities as the built-in OS X Recovery: reinstall Lion or Mountain Lion, repair the disk using Disk Utility, restore from a Time Machine backup, or browse the web with Safari.

You can also run the Mac operating system directly from an external drive rather than your built-in startup disk, this is handy if you are testing new versions of the Mac OS. The process is different to the one described above though, and we cover it here: Read about How to run macOS on an external hard drive here.

Do you know that mini heart attack you get when your Mac crashes or would not start? It is the worst feeling in the world, especially if you have a lifetime's worth of work stored inside your machine. What should you do in these situations? As you are probably have been advised many times, backing up your data regularly is a great practice. For Mac users, setting up an OS X Recovery Disk would be beneficial when trouble strikes. For example, it is conducive to Mac file recovery while you find data lost.

The OS X Recovery Disk is a native but hidden recovery volume on your Mac hard drive. This feature can be used to start up your machine and perform emergency maintenance services such as repairing a corrupted drive by running Disk Utility, surfing the Internet to assess the problem you might be experiencing, or downloading any necessary updates. You can also use the OS X Recovery Disk to reinstall your operating system and restore lost data from Time Machine backup.

Since OS X Mountain Lion, everything went digital and maintenance-minded. Mac users could no longer depend on physical recovery disks to help them fix any problems on their machines. But what how can you access this hidden partition if something goes wrong with your hard drive? You can always connect your computer online and initiate the OS X Internet Recovery feature, but realistically, you may not always have an internet connection. This method will also not work if you had upgraded an old Mac to run on a newer version of OS X.

It will take some time for the process to complete. When the software prompts you that it is done, click on the "Quit" button. Eject the new recovery disk and keep it in a safe place. You will be able to use the disk when you need it the most. It is also a good idea to update this disk regularly.

If you just want to recover deleted or lost files from Mac hard drive, you can rely on a free data recovery program to help you do that. For example, Recoverit Free Mac Data Recovery. This file recovery freeware for Mac is dedicated to recovering data on Windows or Mac computers. If you want to retrieve data from an external device, like an external disk or memory card, connect it to your computer and the stored data can also be recovered.

Having a built-in recovery solution is excellent, especially when you tend to lose or misplace recovery disks. It would be great to learn how to use it and have a copy of it stored outside the machine so that you will be able to access it when you cannot do it straight from your computer. Fail to do it? Only want to recover data? Recoverit can help you. Download it and recover lost files for free.

An error message may appear showing that the security settings do not allow it to use an external startup disk. If you bump into this message, follow the prompts to restart, then hold down Command+R to open macOS Recovery. Click the Utilities menu and choose Startup Security Utility. Enter the password you use to sign into this Mac. In the Allowed Boot Media section, change the option to Allow booting from external or removable media.

Even if you completely wipe your Mac, and start again from scratch, the Recovery partition should still be there to make it possible to reinstall macOS, restore from your Time Machine backup, and repair or erase your hard disk. We look in detail at what you can do in Recovery mode here.

Starting with macOS 10.13 High Sierra non-Apple apps can no longer access your startup disk directly. Even though Disk Drill always accesses drives and partitions for deleted data recovery in read-only mode only, even that access is removed at the OS level. Not only Disk Drill is impacted.

All system modification apps, UI tuners, many professional backup and disk cloning solutions, heavily integrated system-level management suites are facing the new dilemma. As of today (September 24, 2017) macOS 10.13 High Sierra is only available as a Release Candidate (GM Candidate, as Apple calls it), not even the Golden Master version, as used to be in the past years. Thus, many experts acknowledge: this upgrade might be cumbersome for many users.

If you are in need of data recovery from any storage device other than your startup system drive, nothing changed for you. Disk Drill is ready to serve you out of the box! The same is true if you are running any macOS/Mac OS X version prior to 10.13.

If you need to scan your startup drive (main system disk or partition) for deleted files on the latest macOS, Disk Drill now offers several simple convenient workarounds that will help you get your lost data back in the safest way. These workarounds require 5 to 15 extra minutes of your time, and basically ensure Disk Drill can access your startup drive safely preventing any further file activity on it that could overwrite precious data you are looking for. So, starting with Disk Drill 3.5 running on macOS 10.13 High Sierra, these are the options available to you before the lost data can be recovered from the startup drive:

Also we wanted to assure you that we are already working on a more integrated solution that might get the recovery process for startup drives back into the normal more simplified course of actions. Until then, we are here to help you out any time, more than we always were.

Same as my situation, but once I've use diskutil apfs decryptVolume to decrypt volume, but after I enter this command, quickly it crashed my macOS 10.13, then I can't boot my mac and also can't read any files anymore, after I boot into Recovery Mode to unlock the volume with my passphrase, all the encrypted files on the volume can be list and not modified, but they can't decrypt by FileVault2 and let me read raw encrypted data, and I use diskutil to check crypto users, that said I'm in decrypting action but paused state of my volume?

I had the same problem on my 15" MacBook Pro early 2011 with a FV2 encrypted homemade fusion drive after it slept during install. To make matters worse it wouldn't even boot into the recovery partion (although it would boot into the password recovery utility). I ended up creating a bootable USB drive so I could get to an OS 10.13 terminal window.

I suspect it is updatePreboot that causes this problem during install. I have a working theory on why it is happening: The OS Installer reboots the system. After restart the CoreStorage volume is unlocked and converted to APFS after which the OS install process begins. When the install is complete, just before the final reboot, updatePreboot is applied to the FV2 boot volume. We have already shown that updatePreboot will fail if the FV2 volume is locked and I'm fairly sure FV2 volumes lock (or have the encryption keys destroyed) at sleep. Following this logic: if the machine sleeps during (or at the end of) the install process but before updatePreboot runs, the Preboot volume will fail to get updated. The machine then reboots: EFI sees the FV2 boot volume so it looks to the (improperly updated) Preboot volume for authorized users. EFI fails to find any admin users since updatePreboot could not read them from Open Directory on the locked boot volume so it displays the generic "disk password" prompt. This is also why neither the recovery key nor an icloud account will unlock the drive.

I then tried "diskutil apfs updatePreboot disk2s1". It failed with -69569 error because it was unable to open Open Directory database from: "/Volumes/Macintosh HD/var/db/dslocal/nodes/Default". The path "/var/db/dslocal/nodes/Default" does it exist. Tried running some "diskutil unmountDisk" commands on disk0, disk1 and disk2 but they all failed. Debating if I should make a symbolic link. May also try recovery USB to boot into it to see if it changes anything. Not sure how unencryptvolume (and long wait) will help here as the issue seems to be a mounting problem.

But creating a bootable USB disk allows you to install or update macOS on multiple systems without having to download the installer on each Mac. This can save quite a bit of time, considering the most recent versions of macOS have an installer size of 12GB.

You can also use the built-in recovery tools that come with the macOS installer to troubleshoot and fix different kinds of issues. These issues include when your Mac refuses to boot or when you need to recover system files that seem to be lost.

Another benefit of using a bootable disk for a macOS installation is that you can perform a clean installation. A clean installation allows you to get rid of junk apps and files that may have accumulated over time. This almost always results in a Mac running faster after a clean install, since macOS has started over with a clean slate.

In the event that you are already running the latest version of macOS, you might not see the option to download the installer in System Preferences. In that case, use the App Store method detailed above. This will force System Preferences to download the installer, which you can then use to create the bootable disk.

You should now see an option to select your USB drive as a startup disk. After selecting it, your system will boot off your USB drive and enter macOS Recovery with the macOS Monterey installer appearing on your screen. If you want to erase your disk first, to do a clean install, quit the installer and run Disk Utility from the Recovery menu. You can format the drive and then go back to the Recovery menu and install macOS Monterey. 2ff7e9595c
