Hello everyone, I'm having a little issue with mounting my external hard drive lately. I've tried quite a few methods in hope of getting it to work again, but so far, no luck. I hope someone can help me solve this issue, or those who have the same problem may also share your insights. My external hard drive was working fine about a week ago. But one day, I ejected the hard drive and the icon disappeared, so I thought it was safe to unplug it. When I did, it said the hard drive was not properly removed. It still works fine when I use it the next day, but the same thing happened. It said the drive was not properly removed after I ejected the drive, waited for the icon to disappear, and then unplugged the drive. After that, it never works again, and the attached images are the info I got when I tried to mount or run first aid on this drive. Please help & thank you in advance! Computer: 27" iMac - MacOS Monterey External Hard Drive: WD_Black 4TB. APFS encrypted

On MacOS, I understand NSFileSystemFileNumber is an inode number. And inode can be reused by filesystem after original file is deleted. Suppose one file is never deleted, will its NSFileSystemFileNumber change? For example, reboot? OS upgrade?

chdir (2) with relative paths that involve firmlink black magic behave awkwardly. Consider the following sample code: #include <assert.h> #include <string.h> #include <stdio.h> #include <unistd.h> int main(int argc, const char * argv[]) { chdir("/System/Volumes/Data/usr/libexec"); assert(strcmp(getwd(NULL), "/System/Volumes/Data/usr/libexec") == 0); chdir("cups"); assert(strcmp(getwd(NULL), "/System/Volumes/Data/usr/libexec/cups") == 0); return 0; } The problem is that the second chdir will jump to "/usr/libexec/cups". I have reported this issue via the feedback assistant (FB11432545) but it got closed as "Works as currently designed" without much explanation. Especially if you take into account that FTS (3) and tools like ls (1) and find (1) are broken: $ find /System/Volumes/Data/usr/share | grep '^/System/Volumes/Data/usr/share/' | wc -l 179 $ find /System/Volumes/Data/usr | grep /System/Volumes/Data/usr/share/ | wc -l 14956

Hi, I've installed Monterey Beta 1 .... and then did an OTA update to MR B2. After the update to MR B2 ... I've started to get this "Volume Hash Mismatch" in my notification center ... I've tried to reboot into Recovery, and do a "First Aid" an all volumes in my MacBook Air's ssd ... But this message still re-appears. Any idea why this happens? or a fix? cheers, Daniel.

This is a question I have concerning features on IOS that don’t exist as far as I am aware but I think should. What were the software developers thinking when they said yes let's not have separate volume controls. When I am on the phone for example and I want to watch a video or listen to a voice message I can't hear it because the call overrides the media, I know this is not just me everyone has to deal with the missing feature of separate volumes it would be so nice to access the control centre click volume and have 4 options 1 for media another for notifications a third for calls and a 4th for alarms every other phone manufacture has this feature including android. Another annoying feature that apple lacks is the fact the torch cannot be used if the camera is in action on FaceTime or camera - again this can be included by a simple software update I’m sure it is a case of a few l more lines of code? And a simple feature all other phones have. Not many people seem to care about this but I know many would think wow that's so much better if it was bought out or maybe it’s because they don’t know any different. Small things make a big difference to user experience. I wonder if there is already a plan to bring these features IOS. it would be very useful don’tyou agree Tanks for reading -George

Greetings to you! For now; hope you are all healthy !? To my question: 1) Who knows this message (hard disk utility first aid) - Warning: MT mapping is not completely referenced? Now had no (or only the usual Catalina) problems, but occasionally run first aid over it. This message comes at "Container disc2" at the end of the check. The same when checking from "Fusion Drive". The same message comes. With Macintosh HD 1 + 2 data - does this message not appear? Couldn't find much about it on the net, tried some suggestions https://discussions.apple.com/thread/251159425 but didn't do anything. Ne reinstall. I still did before I don't know what that means - I have backups with TM anyway. That with the reinstall. was a recommendation to fix the problem - whatever the consequences could be ....? 2) Did someone check that with "first aid"? 3) If so. Does this message come from Erste H. only for "Container disc2" and "Fusion Drive"? I found that after Catalina installation. Clean installation didn't help either? I was unfortunately not able to load a ScreenShot ??

Hey guys, I have the problem that my 2013 MacBook crashes frequently since upgrading to Big Sur. This means that all of a sudden the screen freezes, the fans turn up and all of a sudden the MacBook is off. In Catalina, through research I found out that it's because of the Thunderbolt driver (AppleThunderboltNHI.Kext etc.), which I had always renamed in Catalina using recovery mode (... .kext.BAK). This solved the problem. But now since Big Sur I can't rename the Kext files anymore because I'm only in read-only mode. So I wanted to ask here if there is a possibility to rename the files again? Otherwise the MacBook still runs really well!

I'm trying to use solution below to fix a monitor display issue, but I'm unable to edit the system files on Monterey. Does anyone know if there is another way to either resolve the monitor issue or gain Read/Write access to the System folder? Download the ruby script: https://gist.github.com/adaugherity/7435890 Run the script with "ruby" followed by the script location/name Move the folder created by step two into Displays/Contents/Resources/Overrides/ Reboot Source: https://forums.macrumors.com/threads/big-sur-force-rgb-mode-for-displays.2268099/

Hi everyone, I hope you can help me with this issue. I attached USB SSD drive with encrypted APFS, from iMac (MacOS 10.15.7) to the new Mac Studio (M1 Ultra, MacOS 12.5). After asking for the password, the directories were not read. When I get the SSD back to the iMac, it is no longer recognizable. I tried disk utility, first aid: Tried to mount: Also, tried fsck_APFS on the three : Is there any hope that I can recover the data on this disk? Thank you all for your help! Best, Yasser
