i'm stuck and urgently need assistance! I have rMBP 15"(MacBookPro **A1398**(**mid 2015**)), currently running **Big Sur**. The idea is simple, i just want to jump on Sequioa via OCLP(my rMBP is not supported anymore), since for development purpose it requires to have latest version of MacOS. The problem appears here, since i have a bunch of data / apps / settings and etc, which never was saved before and i would like to not lose it before upgrade process. I have an empty SATA3 SSD and SATA3 To USB adapter. Plus additional Backup drive (NTFS) where i store files from my personal Windows machine. What i'm trying to achieve : 1) Create **Image** disk with full clone of my current MacOS BigSur AS IS, which should contain all files / settings / apps and etc. After that i want to copy that **Image** on my NTFS backup drive and possible later i will move it to Cloud(e.g. OneDrive). 2) Create a full bootable clone on external SSD and keep it there temporarely while upgrading via OCLP. If it crashes(i hope its not), then i can erase\wipe my internal ssd and just clone again from external SSD freshly copied version and repeat process(or maybe full wipe and clean install, which I really don't want to do, its completely other story / question) Note #2 seems to be not a huge problem at all, since i could use at least basic Disk Utility for such job. Note #1 its more complicated, since i'm not "advanced" user of MacOS, to be honest i'm not even sure if that scenario possible / applicable, because i have no idea how in fact looks fully bootable **Image** of cloned MacOS system, i guess it should be the same how it works in Windows manner where you get **Image** as one file with format "**.iso**", but for Mac it will be one file as "**.dmg**". Also, i had in mind to use Time Machine, but this is much more complicated and not best solution for my case, since of you can't just copy/paste files from Time Machine, because under the hood it uses symlinks. Any advice appreciated. PS Could be possible through 3rd party apps like **CCC**, but unfortunately i didn't found anything similiar on my request...

I recently purchased Carbon Copy Cloner, and set it up to backup my Mac to an external SSD (Crucial X6, not especially high-performance). This works wonders, and I can finish an incremental backup in ~1 minute. I would also like to backup to a makeshift NAS (a Raspberry Pi 4 running Samba, with a mechanical hard drive connected to it). Unfortunately the performance of this setup is unacceptable: any kind of backup, even if essentially nothing was changed, takes many hours (say ~8 hours). This is so long that I'll often have to pack up the laptop to take it to work before the backup is finished. Clearly the main issue is with small files; on CCC's progress graph I see that the rate of processing files is in the order of a few tens of files per second. Looking at CPU usage in the Raspberry Pi, it is always close to 100% -- which is very odd for processing tens of files per second at a transfer rate of << 1 MB/s. For the initial backup, I mounted this hard drive in a faster PC and got improved performance, but not too much, say 2 or 3 times faster. Using the PC, rather than the Raspberry Pi, as the NAS is not an option, and nevertheless it is still too slow. Networking speed is not the issue: I can easily get upwards of 50 MB/s when copying large files. The Pi is connected by gigabit Ethernet, and the Mac by WiFi 6E, right next to the router -- it can and does achieve faster-than-gigabit transfer speeds in other contexts. It seems like this an issue with Samba. I'm thinking there must be some sort of configuration I can change, either on the server (Raspberry Pi 4) or the client (Mac) to achieve a considerable speedup and reduction in CPU usage. **How can I improve Samba performance through client- or server-side configurations to achieve improved performance**?

## Problem APFS is amazing... and infuriating with its lack of tools available. What I'm trying to do is simply an equivalent of btrfs send --no-data -p /snapshots/parent /snapshots/child ## My investigation 1. Most of the google-fu returns usages of tmutil - tmutil is able to listlocalsnapshots / deletelocalsnapshots / localsnapshot (create) - tmutil compare doesn't accept 2 snapshots - tmutil compare EXISTING_SNAPSHOT returns cryptic & undocumented *Must specify a snapshot root when performing a machine comparison.* - tmutil calculatedrift doesn't seem to be related to APFS snapshots - tmutil contains some undocumented options, but nothing related to snapshots - Snapshot created by tmutil have hardcoded com.apple.TimeMachine.YYYY-MM-DD-HHMMSS.local naming format 2. diskutil contains limited snapshots support - diskutil deleteSnapshot works as intended - diskutil listSnapshots list snapshots with sizes and some metadata (unlike tmutil) - No facility for creating snapshots 3. Kernel contains fs_snapshot_* syscalls - The documentation is almost non-existent, but [a single man page is available](https://github.com/apple/darwin-xnu/blob/master/bsd/man/man2/fs_snapshot_create.2) - All usual operations (fs_snapshot_delete / fs_snapshot_list / fs_snapshot_create / fs_snapshot_mount) are supported - GitHub ahl/apfs [hosts a small utility](https://github.com/ahl/apfs/blob/master/snapUtil.c) which demonstrates the syscalls usage - fs_snapshot_list list **only** com.apple.TimeMachine.* snapshots - Any write operations (e.g. fs_snapshot_create) end up with application being killed with fs_snapshot_create: Operation not permitted (probably due to documented in the man reason: "require an additional entitlement") 4. Commercial app, Carbon Copy Cloner, is able to manipulate snapshots - For obvious reasons they don't disclose how they do that ;) ## Help? ;) Is there any method of getting a diff between two snapshots? Any documentation how they can be managed? The only naïve approach which because of speed is not feasible is running rsync between r/o mounted snapshots... but this is just stupid.

Macos Sonoma v14.6.1 Carbon Copy Cloner v7.0.4 My pwSafe vault is stored on iCloud drive which enables access from my ios devices. Sweet. I'm aware iCloud drive is backed-up, but that only gives me access to the most recent backup of the vault. I have CCC configured to backup the pwSafe iCloud folder, but that also only gives me the most recent backup version of the vault. Can I configure CCC to provide historical backup versions of my pwSafe iCloud folder in a similar manner to how it makes volume backup snapshots?

I ran First Aid on an external APFS-formatted HDD using Disk Utility on macOS. During the process, I noticed that the logs mention snapshots with the prefix “com.bombich.ccc”. However, I’ve never installed Carbon Copy Cloner (CCC) on this mac. Some utility of CCC are now integrated in macOS? Here is the original log from the First Aid operation:

I've been encountering difficulties with my bootable external drive on my Apple Silicon M2.I can boot Successfully on M1 mac. I've tried creating the bootable drive using ASR, Carbon Copy Cloner, and SuperDuper, but unfortunately, the system doesn't boot up, displaying an error message indicating that the OS needs to be reinstalled on the selected disk. Here are the steps I've taken so far: Checked compatibility: Ensured macOS version on the external drive is compatible with Apple Silicon. Recreated the bootable drive: Used ASR, Carbon Copy Cloner, and SuperDuper to recreate the bootable external drive. Reset NVRAM/PRAM: Attempted to resolve the issue by resetting NVRAM/PRAM. Checked external drive connection: Ensured proper connection and tried different ports and cables. Checked for errors: Ran Disk Utility from Recovery Mode to check and repair any disk-related issues. Despite these efforts, the problem persists. The external drive is formatted with the APFS file system, and I've verified that the cloning tools are up to date. I would appreciate any insights or suggestions from the community on how to troubleshoot and resolve this issue. Has anyone else experienced a similar problem with bootable external drives on Apple Silicon, and if so, how did you successfully address it? I have tried Monterey, Ventura and Sonama as well. Thank you in advance for your assistance!

I recently got a new Lenovo dedicated gaming laptop and am wondering how to go about cloning, if possible, a Boot Camp Windows 11 partition. I have many files and games from my childhood I cannot find online anymore and installing it on the new PC which comes with two 1 TB SSDs?

I just bought a new Mac Mini M1 running Ventura 13.6 (22G120) and want to setup Carbon Copy Cloner 6 to backup my computer to an external drive. My destination is a folder within said drive (as I have other files and backups on it). Should I select the whole internal drive "Macintosh HD" or just select the user folder: Macintosh HD/Users/myusername? If I select "Macintosh HD", will I be able to just drag and drop all the applications and settings/preferences if my source SSD were to be formatted to factory settings? If not, then I'd rather save some space on my external drive and just backup the personal files from the Users/myusername folder. Thanks.

I’ve just migrated from a MBP 2014 to an MBA M2 and have attempted a backup for the first time, using the same external drive as before. Everything seems to work just fine except that I am wired that "macOS has negotiated an extremely low connection speed to this device". And it does appear slow (expected completion about 13 hours rather than the usual 20 minutes I’ve previously experienced). How do I fix this? If anything things should be faster (using USB-C rather than whatever the 2014 MBP had and a much faster source).

My 2013 27" on Catalina 10.15 is running out of disk space. The internal 3TB HDD is broken and I have kept it working by splitting the fusion drive and running it off the still functioning but very small internal128GB SSD. In order to download a new OS and create an installer, I decided to use Carbon Copy Cloner to clone the install onto a new 480GB SATA SSD, connected via a USB to SATA adapter. The CCC process went smoothly and it created a clone in about 25 minutes. When I try to boot from from the clone, the SSD is recognised at the boot picker stage (holding down the ALT/OPT key on boot) and it begins to boot but when the progress bar has gone about 3/4 of the way across the iMac just shuts down. I have used CCC for years and always found it super reliable. Has anyone got any tips on how to troubleshoot this one?

I have a new Macbook Pro 2017 (No touch bar) that will not boot from an external USB-C SSD drive. I cloned a 2012 Macbook air using Carbon Copy Cloner onto the drive and I have confirmed that the drive will boot from the MB Air. The Air has the newest version of Sierra. (10.12.5) I have a 2016 Macbook Pro w/Touch bar and it will also boot to that machine. I have tried to bless the drive in recovery mode (That did not work) I would like to clone the Air -> new MB Pro 2017 For a long term solution, I would like to be able to make bootable backups of the new machine. **EDIT:** *I was able to clone the new OS on the new Macbook 2017 and it will boot to that.*

My MacBook Pro (running 10.11.6) has a swollen battery, so I shut it down promptly and am sending it in for service. I have an up-to-date backup (a bootable backup) made with CarbonCopyCloner. The servicing of the Mac will take a while (maybe a week or so). In the meantime, a lot of my passwords are unknown to me. They're mostly auto-generated fully random passwords, saved in either Keychain Access or in Firefox's password-saving feature (or sometimes both). Obviously I know my login password and the passwords to unlock my keychains (though I often just use the default login keychain), but I don't know most of the other passwords. Since I do have email access through other devices, I *could* reset various passwords. But that would be a lot of hassle, and then when I get my Mac back I would have to update the keychains and Firefox. I have other computers available running Linux (Ubuntu) and Windows (both 7 and 10) to which I can connect my CarbonCopyCloner backup. I also have an older MacBook Pro from 2010 that I almost never turn on; I think it's running Mac OS Lion (10.7) but it might be Maverick (10.9?). I'd rather not use that one if I don't have to. **How can I get my passwords out of the keychain(s) and Firefox data from within my backup?** (For completeness, I actually do still have my laptop with the swollen battery since they're sending me a box in a couple days to use for shipping it. But I'd *really* rather not turn it on given the swollen battery and potential for damage, plus I'm curious about this question for its own sake.)

I want to migrate all data from my existing 2015 MBP that runs on Big Sur to the latest 2021 MBP with M1 Pro chip. I want to be able to transfer all files and all settings to the new MBP and this includes the hidden .ssh folders, /etc/hosts files, to name a few. I have read about Migration Assistant being able to do this over Wifi but quite unsure if all the data & apps will get transferred or not OR if it cause issues because the OS versions will be different. Can I use CarbonCopyCloner and "clone" my old OS + data on the new M1 MBP which runs on a new version of MacOS? Which OS would be present after cloning? Would the new OS cause issues especially since I am on an Intel MBP. I will have only a weekend to complete this process before I have to ship my old MBP so looking for best practices from people who have completed this process before. Basically want an exact copy of what I currently have in my 2015 MBP to avoid any troubles with office work.

I just updated from Yosemite to El Capitan. I have two backups, one being done with Time Machine and one with Carbon Copy Cloner. Both sparsebundles are stored on a NAS (Synology DS213). After the update everything still works as before. I can do backups and verifying them shows them as being there and functional. However, navigating to the Backup folder on the NAS using Finder shows the sparsebundles as folders, not as sparsebundles. So instead of: Backup.sparsebundle I now have: C33YRS~D Trying to open them launches Terminal. I restarted the MAC and also the NAS, the sparsebundles are still displayed as folders. What happened? Does anybody have the same issue? Can I just rename these files back to their original name or is there something else I am missing?

i was hoping to ask if there a simple way to put a Catalina user folder on a external volume and be able to clone/BU using Time machine or CarbonCopy Cloner etc I read some comments about using the terminal or a symlink app but the answers/Info where mixed.. Any advise appreciated

Is it possible to clone a Mac directly to another Mac with Carbon Copy Cloner? I just need an answer for macOS 10.13.6. Both machines have exactly the same hardware and OS, except that one of them is running with CPU Intel i7, the other with i9, and one has 512GB disk capacity and the other 256GB. Everything else, including the model A1990, and all other specs are the same. I am thinking of this so I can bypass the hassle of cloning to an external harddrive first and then restore to the 2nd Mac. I just need both Macbooks to be synced, so that if one is down for repair, there's practically no downtime. If CCCloner does not offer this, is there any other way to do this? P.S.: I am intending to always restrict my disk space usage to less than 256GB so I do not face problem of no disk space on the Mac that has lower disk capacity. P.S. No 2: I intend to do this syncing between machines on a regular basis (say once a day). Some have mentioned Migration Assistant. Is Migration Assistant suitable for such a frequent task?

We're using an Intel Mac mini running Catalina as a build machine, running a lot of specific and custom software. We want to update that build machine to Big Sur in order to build apps for the latest iOS, unfortunately we're out of disk space on that machine (128GB model). Management took the opportunity to upgrade and bought a Mac mini M1 to replace it, expecting to clone or restore a Time Machine on the new machine. We have a huge technical debt on this, the person building it has left and is no longer in contact with our company, so rebuilding manually on the new mac is not a realistic option without spending a lot of resources on it. Is there any way to clone the filesystem on the new machine and have it work "out of the box"? A direct clone is not going to work since only Big Sur and up is supported on M1 (if I remember correctly,) but maybe cloning on a bigger external drive, updating macOS, creating another clone of that and restoring it on the new machine? Has that any chance to work?

Im running two macs on my home office setup; a 2010 Macbook Pro and a 2011 Mac Mini. Both have been upgraded in the past with Crucial SSDs and for each I used the Carbon Copy software to clone the drives before installation. I noticed the other night I couldn't Airdrop between my two machines. I figured this must have something to do with the clone and was wondering if there was a workaround to fix this issue? Ive also noticed issues in the past with apps like iMessage not updating on both machines, only one or the other. For the time being Dropbox does the trick, but having Airdrop operational between the two would be ideal. Any advice or feedback would be greatly appreciated. Thanks in advance!

**Background** According to the Carbon Copy Cloner documentation [CCC4 cannot clone the Recovery HD from an APFS source to an HFS+ target](https://bombich.com/kb/ccc4/cloning-apples-recovery-hd-partition) : > Note: CCC v4 requires an HFS+ formatted source for creating Recovery HD volumes on HFS+ formatted destination volumes. If your source volume is formatted APFS, CCC v4 will not be able to create (or update) a recovery volume on the destination. CCC v5 adds support for APFS recovery volumes. According to other CCC documentation, [spinning platter target disks should be formatted as HFS+](https://bombich.com/kb/ccc5/preparing-your-backup-disk-backup-os-x#high_sierra) : > Starting in macOS High Sierra, both APFS and Mac OS Extended (Journaled) are acceptable formats for a backup of macOS 10.13. Mirroring Apple's recommendations, we recommend that you choose APFS if your destination device is a Flash storage-based device (e.g. an SSD) and will be used to back up 10.13 or higher. Choose Mac OS Extended (Journaled) if your destination device is a spinning-platter-based device (i.e. a hard disk drive, or HDD), or if you are backing up an operating system older than 10.13. Anyone who's upgraded to High Sierra with an SSD internal disk knows that your startup disk was automatically updated from HFS+ to AFPS as part of that upgrade. A Recovery HD on an external clone might not seem like that big of a deal: you could use a bootable USB thumb drive, or maybe Internet Recovery, if needed. However, *FileVault requires a Recovery HD in order to encrypt the volume*, according to Apple's support documentation: > Without a Recovery System, FileVault won't encrypt your startup drive. https://support.apple.com/en-us/HT204837 > You don't need a recovery system to install and use macOS, but without it you can't use FileVault, set up a firmware password, or use Disk Utility to repair the disk. https://support.apple.com/en-us/HT201316 **The Question** Given all of this, *how can I create a bootable, encrypted clone of my APFS High Sierra source drive using Carbon Copy Cloner 4 (CCC4) and using external HFS+ disks?*

I've used Carbon Copy Cloner to copy one external SSD, which is currently about to die, to another one. I also have an online backup of the external drive, but I want to confirm that my cloned copy is exactly the same as the old one. I can compare individual files using md5sum. Is there a tool I can use to compare every single file on two drives?
