APFS Volume on ext. Disk not mountable - space manager is invalid

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 fil...

123$ diskutil verifyvolume disk4s1
Started file system verification on disk4s1 DISK-XYZ
Verifying file system
Volume is already unmounted
Performing fsck_apfs -n -x /dev/rdisk4s1
Checking the container superblock
Checking the space manager
error: (oid 0x400) sm: invalid o_cksum (0x74dfcb428a5691c4)
error: verification/reading of the spaceman object failed: Illegal byte sequence
Space manager is invalid
The volume /dev/rdisk4s1 could not be verified completely
File system check exit code is 8
Restoring the original state found as unmounted
Error: -69845: File system verify or repair failed
Underlying error: 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

Qt on MacOS not finding correct (?) LLDB

macos xcode open-source

I have resurrected a C++ project I was working on a few years ago in Qt (MacOS), and can no longer get debugging to work.

                                  I have resurrected a C++ project I was working on a few years ago in Qt (MacOS), and can no longer get debugging to work. The problem seems to be that it is trying to use the wrong (old?) version of LLDB. The current macOS version is 12.6.8. I'm not sure what the version was when I set it all up.

In Preferences > Kits > Debuggers, it lists as 'Auto-detected' both Applications/Xcode.app/Contents/Developer/usr/bin/lldb, and /usr/bin/lldb. The latter is flagged (popup appears when hovering) as 'Cannot determine debugger type' (and with a red warning marker). The other entry seems fine.

When I look in Projects > Build and Run and hover over Build (for this project) the popup window tells me 'Not recognised engine using /usr/bin/lldb', and when I try to run the code in debug mode I get the message (in Application output) 'Unable to create a debugging engine'.

It seems that Qt is finding two versions of the debugging engine, one of which is presumably OK and the other not, and then tries to use the wrong one. There is no option in the list of debuggers in Preference > Kits to remove the problematic one or to set a default.

How can I figure out these dependencies to get my project to compile?

Apple Notes - quickly open multiple specific notes

macos notes.app

Is there a way (Apple Shortcuts or other) to have a command that will launch the Notes app on macOS **and** open separate windows for multiple of your favorite notes? **Use Case:** I would like to have 3 separate notes open that I'm working on, and have them positioned nicely on the screen.

**Use Case:**  I would like to have 3 separate notes open that I'm working on, and have them positioned nicely on the screen.  At the end of the day I close them all... and then tomorrow press a button to open all 3 notes again and restore them to their positions.  (Restoring window position is *a nice to have*... I'm mostly concerned with being able to open up multiple Notes in separate windows at the touch of a button.)

I don't even really care which language... could be Apple Shortcuts, AppleScript, or even Python. (Maybe one of these jumps out as the path of least resistance?)

How to enable horizontal scroll in browsers on a mouse with separate horizontal scroll (logitech mx)?

osascript "authorized to send Apple events to System Events. (-1743)" when invoked via JumpCloud

macos applescript command-line monterey automation

I have cooked up a JumpCloud Command to automate the configuration of desktop backgrounds. I can get the command to run on a test system (Monterey, 12.4) via Shell if I approve a dialog asking for permission. When I execute via JumpCloud, I get: ``` 59:74: execution error: Not authorized to send App...

59:74: execution error: Not authorized to send Apple events to System Events. (-1743)

The command itself: ``` target_user=$(w | awk '$2 == "console"{print $1}') export target_user sudo -u $target_user osascript Security & Privacy > Privacy > Automation" but there are no apps listed under "Automation." Under "Full Disk Access" there's a check for "jumpcloud-agent" ... perhaps I can extend that somehow?

                                  I have set the Mission Control key in BetterTouchTool to execute an AppleScript and it worked fine before the update from Mojave to Montery which I just did

    do shell script "../bluetoggle.sh"

content of file is

    #!/bin/sh 

    blueutil -p toggle

but can't execute in BetterTouchTool.. it says

Executing file from Terminal works flawless.
    
Executing another script (do shell script "../karaprof.sh") in BetterTouchTool with following content to switch profile in Karabiner also works perfectly

    #!/bin/sh

    pro0="e"
    pro1="g"
    
    cli='/Library/Application Support/org.pqrs/Karabiner-Elements/bin/karabiner_cli'
    
    name=$("$cli" --show-current-profile-name)
    if [ "$name" = $pro0 ]; then
    "$cli" --select-profile $pro1
    else
    "$cli" --select-profile $pro0
    fi

So my guess is I need to set permission for BetterTouchTool to execute scripts in Terminal, but how? I can't figure

External display color changes when MacBook lid is closed

How to force EDID override on Intel Mac running Sequoia

                                  Working with a 2020 MacBook Pro 4TB on Sequoia 15.6.

In the past I have edited EDID override plist files to get custom resolutions and HiDPI on external QHD displays.

I have also used BetterDummy/BetterDisplay to achieve this, but that app no longer works with Intel Macs (according to the developer, at least not for getting HiDPI resolutions).

In the past (not sure which macOS version it changed on) you could edit display overrides in /System/Library/Displays/Contents/Resources/Overrides.

It is no longer possible to do this, even with SIP disabled as /System is now read only.

A workaround was to place a custom override in the folder: 
/Library/Displays/Contents/Resources/Overrides

However, it seems that overrides in this location are no longer read by macOS.

I am trying to get HiDPI (at 1980 x 1080 or 1600 x 900) on DELL P2418D and BENQ PD2500Q QHD displays. Both have worked in this was the past, with modified EDID and/or BetterDummy/BetterDisplay.

  Is there any way of forcing EDID override on Intel Macs running Sequoia now?

On older Macs, we were able to run Windows on Boot Camp, which was an alternative to a VM.

Interestingly, if we install Windows on Boot Camp we can, from macOS Parallels, run that Windows as a VM.

Now to the question: we generally say a VM will be a little bit slower than Windows running directly on hardware.

What about a VM from the Boot Camp partition vs. a VM on a macOS partition? Which one is supposed to be faster?

                                  As well as many of the other features talked about during macOS Mojave's release like dark mode and the addition of new apps like Home, another key feature of macOS Mojave seems to be it's heightened focus on both privacy and security. 

As quoted under the "Camera and Microphone Now Require Your Permission" section of this  article: 

> Apple also announced that other categories of data, such as your Messages history and Mail database, will be protected in a similar manner to macOS Mojave's new camera and microphone permissions.

I understand that after the update, when an app requests to use your camera or microphone, you will receive an alert like the one below:

However, I am more intrigued by the following:

> ...other categories of data, such as your Messages history and Mail database, will be protected in a similar manner...

I have been unable to find much information about this online and I do not currently have the pre-release version of macOS Mojave installed and am therefore unable to test this new feature but I am curious to know what exactly this feature will mean. 

Has Apple publicly documented how this will work?

What are some possible causes in a sudden uptick of these errors?

                                  I have been using Google Drive for desktop on my M1 MacBook Pro for a long time, but recently my folders on my google drive stopped syncing suddenly (Some folders are on my windows laptop and drive just basically mirrors them to my mac). On my other devices drive is running completely fine. There is no problem of storage shortage on my account too.

At first, I signed out and signed in but that did not work. So I completely uninstalled and reinstalled it, but in vain. I was seeking help from google high tier support team but nothing really worked for my Mac. 

I have attached what pops out after the sign in. I have searched on the internet for a long time but to my surprise I did not found a single person with my kind of problem. The troubleshooting I tried are mentioned below:

1. Signing out and in
2. Uninstall and reinstall 
3. Using mac on a different network
4. Signing in with a different google account
5. Deleting the DriveFS folder and restarting the computer
6. Reset user preferences on drive
7. Google drive proxy setting change from Auto-Detect to Direct Connection

Any help would be appreciated. Thanks!!

                                  I bought a used Mac Mini from another country on Ebay. 

When I plugged it in the macOS installer listed my country (Portugal) and China as the topmost countries. How does it know this? And why China in addition to Portugal?

Some more details:

- The Mac mini didn't have any internet connectivity at that point, wired or wireless
- I live in an isolated place so only my wifi networks were visible (internet and from a solar inverter) 
- I had plugged a cheap usb keyboard (in my local PT layout)
- This happened twice as I had to return the first Mac mini due to it being the wrong model
- Poking my Sequoia installation I can only find a wifi BSSID database in /System/Library/Frameworks/CoreLocation.framework/Versions/A/Support/factory.db which  does not contain any information about my local wifi networks.
- I had my iPhone close to me while setting this up, but tethering was not being used
