Clone bootable hard drive mac os

You can then boot a loaner machine from this bootable clone and work from it as if working from your original machine see the related documentation below for common questions related to running another Mac from your backup. If you want to update your cloned volume in the future, simply run the same task or schedule it so it runs automatically and CCC will update the backup volume with only the items that have changed since your last backup.

Another scenario in which it would be desirable to do a full-volume clone is when you have purchased a new Mac and you would like to move everything from your old Mac to your new Mac. When you get a new computer from Apple, though, it has a specific version of macOS installed on it, and further, a hardware-specific "build".

Your new Macintosh cannot boot from the older version and build of macOS that is installed on your older Mac, so simply cloning your old Mac onto your new Mac won't work.

Due to this limitation, we recommend that you use the Setup Assistant application runs on your Mac's very first boot or the Migration Assistant application to migrate content from your old Mac to a new Macintosh. You can migrate directly from a CCC backup of your old Mac. Once you have migrated your user accounts and applications using Setup Assistant or Migration Assistant, you can continue to use Carbon Copy Cloner to back up your Mac to the same backup volume that you were using for the old Mac.

This is particularly important if that folder has a lot of data in it and you're migrating to a disk that is smaller than the backup volume. If you would like to retain the SafetyNet folder on the backup volume, don't empty the Trash. After Migration Assistant has completed, then you can move the SafetyNet folder back to the root of the backup volume. Apple Kbase HT What's a "computer-specific OS X release"?

Disk Utility's Restore Function Lets you Create a Bootable Clone

Go watch a movie. Formatting a drive or partition erases all data. If the scrubbing of the drive fails, try again and if it fails, the drive is bad and needs to be exchanged. All new drives have bad sectors, this scrubbing will remove most of them and make for a much more reliable backup. Highly recommended for all hard drives if it hasn't been done before, SSD's no need. Once the scrubbing is finished check under Partition that Option: GUID and Format: OS X Extended Journaled or make it that. Quit Disk Utility.

Scrubbing is only for hard drives and not needed if it was done once before as the bad bits were previously mapped off. However if shock to the drive occurred or the 0x erase wasn't good enough, or there is unwanted data, then of course repeat scrubbing again. I've found 0x for defeating software recovery techniques, 3x seems to be adequate for mapping off the bad bits.

Physically destroying the drive for the utmost sensitive files. SSD's cannot be securely erased, however it might be possible to overwrite one's preious deleted files with new data with a method I've outlined here.

Secure erase data on a Solid State Drive? Later you will use it to update your clone once your on the new internal drive. Use CCC to clone your present internal drive to the external. Do not use the same name as the internal drive on the external, or change it before you boot from the clone using the Finder.

You don't need to mess with CCC preferences for the first clone as it has to to everything. Later when updating the clone it will save the changes between updates and take up much more drive space. If you want to maintain a pure clone, then set that in CCC preferences before doing a update, this is what I advise as it maintains space for later less you need to install additional software or move files for data recovery etc.

Once the clone is finished, use Disk Utility to repair permissions on both drives. Ignore Disk Utility warnings that repeat, those are just changes Apple made. If you have a internal drive switch or install at this time, now is the time to do this.

TimeMachine doesn't have boot to use ability only boot to restore, which mandates your internal drive be immediately fixed and that's not always very convenient for many. To reverse clone, follow the same procedure as above. It's advised to maintain several time dated clones each on separate hardware, this way one can revert to a earlier OS X version or use older versions of software and to protect against accidents and other unseen acts.

How To Transfer Your Mac's Data to a New Hard Drive SSD

Provides maximum software and hardware protection. Do NOT reverse clone onto a new or different model of Mac as there are hardware driver differences so OS X is ever so slightly different. But in some cases it's possible, not going there. Instead to be sure, use Migration Assistant in the Utilities folder and target the clone drive as the source of User Accounts and programs you want to transfer to the other Mac.

See and perform the 12 OnyX cache cleaning routine here, it's optional but if your reverse cloning it's best to also rebuild the cache files so they are free of corruption and maximize the full performance benefit of the reverse clone proceedure. Remember Check MacTracker.

TRIM is wear leveling software so that data is written to the least used areas of a SSD because they have limited write capability. Thus SSD's don't have scrubbing ability to securely delete data off of them. Software and forensic equipment is widely available to read all data on a SSD, included deleted data. SSD's are on many portable tech electronic devices and becoming widespread on computers now.
