I was using a APFS external USB Disk on a PC using a commercial driver. Suddenly it stopped being accessible.. Now I can´t mount the Volume inside the APFS container anymore, on PC but also not on a Mac! If I try diskutils - please see the log:

123$ diskutil verifyvolume disk4s1
Started file system verification on disk4s1 DISK-XYZ
Verifying file system
Volume is already unmounted

The volume /dev/rdisk4s1 could not be verified completely
File system check exit code is 8

Any idea how to fix it? As there is important stuff on the drive I currently draw an image to be held safely while testing on the drive. Or should I try the other way round? How do you evaluate chances to fix it with fsck? Do you know of any other handy tools? Disk Warrior does not handle APFS unfortunately.. ah- btw - mounting read only does not work unfortunately.

123$ diskutil mount readOnly /dev/disk4s1
Volume on disk4s1 failed to mount; it appears to be an APFS Volume which might be locked
Try "diskutil apfs unlockVolume"

Thanks and best, DHVD

I have a macOS/Windows-bootable Mac Pro. Two internal HDDs form a mirror disk formatted in ReFS. How do I prevent macOS Sequoia from nagging me to initialize/eject/ignore those two HDDs each time I start up the machine under macOS? I understand I can do that by adding the

/etc/fstab

file in the following format:

=F21AD81B-B114-456C-B2A0-BF4452E4842D none auto rw,noauto

However, I cannot find the volume UUIDs of those two **unmounted** HDDs in Sequoia. (Disk Utility only shows the volume UUID of mounted disks.) Here is what

info

gives me on one of those two HDDs: ``` Device Identifier: disk7 Device Node: /dev/disk7 Whole: Yes Part of Whole: disk7 Device / Media Name: ST22000NM001E-3HM103 Volume Name: Not applicable (no file system) Mounted: Not applicable (no file system) File System: None Content (IOContent): GUID_partition_scheme OS Can Be Installed: No Media Type: Generic Protocol: SATA SMART Status: Verified Disk Size: 22.0 TB (22000969973760 Bytes) (exactly 42970644480 512-Byte-Units) Device Block Size: 512 Bytes Media OS Use Only: No Media Read-Only: No Volume Read-Only: Not applicable (no file system) Device Location: Internal Removable Media: Fixed Solid State: No Virtual: No Hardware AES Support: No Device Location: "SATA2"

I have a not-so-old WD external partitioned drive that was being used for Time Machine backups & holding older files on the other partition. During the last Time Machine backup it didn't complete and just kept spinning its wheels. I cancelled the backup. I'm now unable to get it to completely mount - Time Machine side won't mount. Ive tried Disk Drill app with no luck - wouldn't mount either. Is there anything I can try using macOS to make it mount & access data? I also have this from latest disk utility first aid session: I'm pretty sure it's formatted macOS journaled. I'd like to be able to use the drive for other purposes if not too big of risk of failing again if it can be repaired. But without know what the issue is - not sure what to do! Thanks for any help. Here's the format info: Sooo, wanted to re-format before recycling or other experiments. Looks like failure?? And finally , then tried first aid again.

When I mount a remote SMB volume with macOS's file sharing feature like as: osascript -e 'mount volume "smb://USER@MACOS_SERVER/VOLNAME" but it fails with Error -5014. What I tried were: - rebooting the client - restarting smbd with kill/launchctl on the server - on/off "File Sharing" at "Sharing" of Preferences app. Any ideas?

I am currently trying to look up the ip address of a mounted smb share for the purpose of accessing it via rclone. Ive tried many solutions, including the ones specified in [This Thread](https://apple.stackexchange.com/questions/10956/finding-the-remote-ip-address-used-by-a-mounted-smb-share) , but these didnt work as the commands couldnt identify the name:

-c 1 nas-smb.local

yielded

: cannot resolve bread._smb._tcp.local: Unknown host

and

lookup bread._smb._tcp.local

to resolve: filename too long

All i have is the local name bread._smb._tcp.local i know from mounting it via Finder - i tried pinging bread.local with the following result:

36 bytes from xyxyxyxy.t-ipconnect.de (unrelated IP): Destination Net Unreachable
Vr HL TOS  Len   ID Flg  off TTL Pro  cks      Src      Dst

I assumed the Destination 192.168.100.10 the IP im searching but trying to connect to that IP directly or mounting to it yielded no result either. How can I look up these IP addresses for .local on macOS?

I have a USB flash drive and can format the stick, but when I try to mount it, the following error occurs: Screenshot of an error message in German that reads: > 'Mounting of 'Ohne Titel' has failed' The error is in German, it means "Mounting of "Ohne Titel" has failed. (com.apple.DiskManagement.disenter -Error -119930873)" I can't find any solutions online and don't know what to do. There is no data on this stick so I can easily format it.

Recently, df started listing over a hundred time machine backup snapshots.  I can get the previous output with df | grep -v backup but I'm wondering why the change and whether there's a better way to restore the previous behavior. Details: Until a week or two ago, df has never listed a Time machine snapshot on any Apple laptop I have owned.  This of course includes most of the nine years APFS has been in use. Starting more than a week ago, it was listing more than a hundred of them.  This behavior persisted after a reboot on 4 July.  But after a reboot on 7 July, sometimes there are none and sometimes there are two. Until the unwanted behavior started, using Finder or find or ls or cd did not cause it to happen.  Nor did it start when using the Time Machine GUI to browse or restore.  Nor did it start when an hourly backup started or ended. As can be seen in an answer and in comments, others have a significantly different experience—which is also disconcerting.

Before you tell me all the security implications I am well aware and this is for convenience testing. I have a server running smbd on Debian 11 and it is configured correctly such that I can mount and use shares normally. However, I would like to share the server /root such that I can read and write files from my Mac which has the tools I like to use. As root on my Mac using the following command: mount_smbfs -f 666 -d 777 //root:xxxx@10.1.1.1/root /Volumes/root/ I can mount the root folder on the server and see and modify files as root on the Mac. But the volume root is not visible from the Finder with hidden items turned on. The files are accessible from the terminal and emacs but I would like to be able to use for example SQLPro to examine some databases on the server but the volume is not accessible or visible from the Open dialog.

I have an OWC Mercury 6G SSD disk on an external drive case. Suddently, I can't anymore mount it nor on MacOS Sequoia nor on Ventura. The disk turns on and... nothing... it is not even listed on Disk Utility It's not a cable problem (I switched 3 different usb-c cables) nor a disk case problem (I tried with two) I can add that when I switched the drive case, Sequoia asked me if it should use the device and I said "yes"... but nothing happens Is the disk broken? Would it be even possible to recover the data inside??

My MacBook Pro froze and I have the spinning wheel. At that time I had my 2TB external drive mounted of which I have never had problems during multiple uses. I had to hold down power and just restart so I could get back on. Now, since then, my MacBook Pro no longer recognizes my external drive. Nothing comes up at all. I tried unplugging everything, restarting the laptop, trying different outlets, and trying every USB port. Nothing. My drive just keeps blinking white-colored light when plugged in. Now, I'm pretty sure nothing was updated in terms of software. It is a WD 2TB Drive.

MacBook Pro 2015, 256GB SSD disk I have created a second partition on my disk to try Linux. Everything was fine, but at some point, macOS disappeared from the boot menu. After some googling and trying some things, I thought it was a problem with the boot manager. I installed rEFInd but it didn't help. So I tried torecover everything using recovery mode. But there was no option to reinstall macOS on the first partition. I could only erase it. I also couldn't mount it to macOS Recovery. I installed OS X 10.10 Yosemite (base for my MacBook) on the second partition and updated it to macOS 10.14 Mojave (to be able to mount that first APFS partition). But I still can't mount it:

daniils-MacBook-Pro:Volumes daniilkk_yose$ sudo mount -t apfs /dev/disk0s2 plz/
mount_apfs: mount: Inappropriate file type or format

Also, diskutil outputs many F's instead of type and name:

Disk Utility doesn't show this partition at all: Is there a way to mount it and get my data back?

Have MacA and MacB running TM and backing up to the same Time Capsule. TC has the internal drive and two attached USB drives - same problem occurs on all of them. Both Macs are latest version - 10.15.7, and TC is the terminal version 7.9.1 MacB will frequently show a "Failed to eject diskX" message in the log. Then cannot mount that sparsebundle on MacA. This will continue even after complete power down and restart of everything - MacA, MacB, the TC, and the external drives - so some setting must be persisted to one of the drives, but what and where? If MacB is offline for a couple of days (wife's computer and not heavily used), and MacA has gone through a couple of daily power cycles, then suddenly all of the bundles can be mounted. When MacB is turned on again, and generates some new backups, then the same problem recurs. Have reported to Apple feedback with full discussion and logs but so far crickets. Will sometimes (rarely) have the same problem with a sparsebundle for a MacA backup also not being mountable on MacA - this usually clears after one reboot. Note that the remount issue occurs when trying to use Finder, or from the command line with hdiutil or open (using DiskImageMounter internally) - usually get a "Resource temporarily unavailable" message. Time Machine itself never seems to have any problem re-mounting these bundles for the next backup. Suspect some XATTR setting, but various experiments have all failed. Any suggestions? Thanks

I have a directory on my Mac shared via NFS. Here is the exports entry: /Volumes/Data01/Projects -alldirs –mapall=dpatterson –network 172.24.0.0 –mask 255.255.0.0 I am unable to mount it on the Proxmox host. This is what I get when I attempt to mount it:

# mount -vvvv macpro-2019.dpc:/Volumes/Data01/Projects /mnt/Projects
mount.nfs: timeout set for Fri Jun  6 13:50:24 2025
mount.nfs: trying text-based options 'vers=4.2,addr=172.24.112.10,clientaddr=172.24.252.201'
mount.nfs: mount(2): Input/output error
mount.nfs: mount system call failed

The /Volumes/Data01/Projects directory is owned by dpatterson. I've enabled full disk access for nfsd on the Mac. The Proxmox server is definitely within the 172.24.0.0/16 network Running MacOS Sequoia 15.3 Running Proxmox 8.4.1 TIA

I have a problem with Jettison , that tries to remount a samba drive, that is protected by a password. It uses the following command line: /sbin/mount_smbfs //[user]@[server]/work /Volumes/work Of course it fails since the password is not present (nor the -N switch) I am aware that it should contain a password, but I do not want the app to know it. So my question is: Is there a way to request the password like this (I am aware this is not correct): /sbin/mount_smbfs //[user]: %keychain->[identified keychain]%@/work /Volumes/work

I'm trying to let Google Drive client to sync files inside mounted dmg. I've added the folder (mounted dmg) to Google Drive client for backup. Everything works fine: upload of new files from my machine, deletion of files on my machine are propagated to online Google Drive and deletion of files from web are propagated to my machine. But when I create a new file from Google Drive Web inside the folder, Google Drive Desktop client can't create file inside the mounted dmg: it always return 'not enough disk space' .. my free space is more than 200Gbyte and the issue happen with 2 files of 100KB each. The dmg file was created for read and write, I can create files inside dmg on my machine but it seems Google Drive can't ... Has anyone experienced same problem ? Thank You

I recently bought a 4 TB naked (no enclosure) external hard drive that I mount via a Newer Tech dock (the ones where you insert the naked drive like bread in a toaster) and is connected to my MacBook pro via FireWire 800. About a month later I wanted to use the drive and it would not mount. Disk Utility reports that it is "Not Mounted". When I connect the drive I get this: > The disk you inserted was not readable by this computer. So I tried terminal commands like: diskutil list which yelds this: I also tried: mount force /dev/disk3 and got: mount: You must specify a filesystem type with -t. and then: mount force -t Apple_HFS /dev/disk3 which outputs: usage: mount [-dfruvw] [-o options] [-t external_type] special node mount [-adfruvw] [-t external_type] mount [-dfruvw] special | node I also tried: diskutil repairVolume /dev/disk3 which gives back: Error starting file system repair for disk3: Unrecognized file system (-69846) and finally: sudo gpt -r show /dev/disk3 which returns: I am at a loss, can anyone give me some advice on how to mount this drive?

I have two folders on a remote server, and I mount them locally on my Mac using MacFUSE and SSHFS, as described here or here : sshfs -o allow_other,defer_permissions myuser@remote.server:/path/to/folder1 /Users/me/folder1 sshfs -o allow_other,defer_permissions myuser@remote.server:/path/to/folder2 /Users/me/folder2 The two mount commands work nicely, and I can access the folders. However, each time I shut down my Mac, the folders get unmounted, and I need to mount them again when I log in. This gets old very quickly. How can I have OSX mount the remote folders automatically each time I log in?

I am new to osx but am very experienced with Linux and Windows. I need to mount a subdirectory of a shared drive so the user can access it without being confused by seeing higher levels in the smb path. I've read around and it appears that Lion only mounts the root of a smb share. I hope this is incorrect so am asking for some tips. Ideally I would mount smb://path/to/the/directory and this would appear for the user to access. The stuff above the directory would not appear. Thanks.

I've set up my time machine to include an external SSD in its backup. Initially it worked, then suddenly started failing within 30 seconds during the 'preparing backup' stage.

My SSD is used for Logic Pro sessions and other files and I regularly work from the sessions that live there. Sometimes I move large amounts of files to that drive to clean out my hard drive. The first time this issue started it lasted 3 weeks before resolving itself (no idea why). In summary - please help me: - further investigate the issue - resolve this issue - setup an alternate way to automatically backup my external SSD (maybe the way I'm doing it is not recommended?) Things I've tried: - first aid-ing the time machine drive and the SSD: no issues - manually deleting in progress and interrupted backup files - toggling the spotlight index privacy to exclude my SSD - waiting awhile while drives are connected (only thing that has worked in the past) - restarting while drives connected - talking to my computer

My Question is seemingly simple. I need to mount an SSH/SFTP volume and make it visible in finder to be able to use it as if it were a local volume (think SMB share). I have tried everything I could find (MacFUSE + sshfs (whatever version), Macfusion (couldn't install),...). Is there anyway to do this seemingly simple thing? It feels like I'm missing something here. Also, I'm not looking for an SFTP client for download/upload. My personal machine is an Ubuntu box, and that's easily doable on that.
