Accessing internal Macintosh HD with Boot Camp Windows To Go install on external drive

I’ve installed a bootable Windows 10 (Windows To Go) install on an external SSD with Boot Camp drivers. Accessing the internal drive while running Windows To Go is not recommended by Microsoft, but they specifically mention problems with corruption when the internal drive has Windows 7 or earlier installed and was left hibernating.

I have macOS Big Sur installed on my internal drive, and I find it inconvenient that I can’t access the files on my internal drive and I want to try mounting the drive — has anyone tried this? Does anyone foresee any potential problems with doing this?

macintosh – Convert multi-layer Paint.NET (pdn) files to Krit (kra)

I am moving to a Mac from Windows and thus moving away from Paint.NET.

I have several multi-layer Paint.NET (.pdn) files that I would like to continue using. How can I move these easily to Krita?

I know I could save each layer as a separate image and create a new Krita project and add each layer one by one. I would prefer a single multi-layer export and import or something simple like that.

I have one solution that I have discovered that I will post as an answer, but welcome any better answers!

Delete folder with subfolder and files from SharePoint Online with a Macintosh

If you or your admin knows PowerShell, you can use the SharePoint PNP library to delete the folder:

#if not already installed
#install-module sharepointpnppowershellonline   #requires PS 4.0 or later.

Connect-PnPOnline -Url https://yourServer/sites/yourSite
Remove-PnPFolder -name Test -Folder "/shared documents"  


You may see recommendations to use the SharePoint “Sync” feature. Don’t. This is a real overkill for just deleting a single folder, and opens up some interesting risks to other site data.


You can use Windows Explorer and map the library to a drive letter. You then display the library in Windows Explorer, click the folder and click Delete. (The items will be sent to the recycle bin.)

Windows Explorer can be very finicky and works for some and not others. You may need to logon to the site with Internet Explorer first. Do a web search with your windows version, browser version and error message for help.

Basic steps:

  • Open Windows Explorer
  • Right-click the Network folder/icon
  • Click Map Network Drive
  • Click “Connect to a Web site that you can use to store your documents and pictures”
  • Click “Choose a custom location” and click Next.
  • Enter the URL to your library. (Just the library, not a view: https://yourServer/sites/yourSite/Shared Documents)
  • Click Next and enter a name and then click Finish.
  • Windows Explorer should open with your library displayed.
  • Delete the folder

menu – Is the Macintosh Menubar Preferred?

The Macintosh menu bar is certainly preferable to me, and there are some good arguments for (and against) its use.

The main argument for a persistent menu bar across the top of the screen is that it becomes an infinitely-large target along the top edge, which according to Fitts’ law makes it much faster to target with the mouse. It’s also notable that in Windows (which, as you probably know, still uses per-window menu bars), many core applications are losing their menu bars entirely behind drop-down menus and disclosure arrows (see Internet Explorer, Windows Explorer, etc.), which makes finding things like the Edit menu (for copy and paste) much harder for users who haven’t memorised the keyboard shortcuts than it once was.

The main argument against a persistent menubar is that it makes the interface inherently modal. While I have a specific application focused, I’m in that application’s “mode”, and I am forced to actively change application focus before I can interact with the menus for another application. If I have a word-processing document open and a web page open in a web browser, it’s not always immediately obvious which has focus (which can make choosing things like “Window > Minimize” have unintended consequences). It’s worth noting that even without a persistent menu bar, desktop window managers tend to be somewhat modal since keyboard shortcuts (e.g. for copy and paste) only apply while a given application (or document) window has focus. Since that limitation seems unsurmountable, perhaps making the interface seem more modal is a good thing (and could explain why Windows users tend to run their applications fully maximised much more often than Mac users do).

It may also be that on today’s 20-inch-and-larger displays the distance between the window you’re interacting with and its menus is too great (the original Mac had a 9-inch screen with a resolution of 512×342 pixels). Compare a modern Mac’s resolution (the one I’m typing on is 1920×1200) with the one below from — the distance of the window from the menu bar could never really exceed 100 or so pixels.

Here’s a great blog entry by StackExchange’s own Jeff Atwood about the relative pros and cons of the Mac menu bar that touches on a few of my points and adds a few more.

macos – I deleted Macintosh HD – Data and now the computer won’t boot even in Recovery Mode

Okay all, I think I messed up really big time.

Was so excited and delighted today to see my brand spanking new MacBook Air arrive (running Catalina). Everything was wokring great; I started Migration Assistant to get it migrating over from my old computer and, after a little while for the preliminaries, it said it was going to be 6.5 hours. So I thought let’s not do this right now, so I can still use the old computer, and cancelled it.

That was my first mistake.

It wouldn’t let me go back to the original state of Migration Assistant; the users were already on the new computer. Okay, fine, I have to go into Utilities to find Migration Assistant on the new computer. But then when Migration Assistant did start up again, it would keep freezing in the early stages, stalled and not progressing – never even got to the part where it estimated time remaining. It did this in multiple ways, whether I was connected through WiFi or Ethernet, direct from the old Mac or through my Time Capsule.

So I figured I wanted to start clean. And this appears to be where I made the REALLY big mistake. I thought “well, I’ll just wipe the data so I can start clean, right?” I tried to followed instructions for a factory reset: went into Recovery Mode (cmd-R), entered Disk Utility, deleted the Macintosh HD-Data partition. I thought that what I was supposed to do next was delete the Macintosh HD partition too. But it wouldn’t let me do that because it was in use. I also tried to reinstall the US, and it wouldn’t let me do that either (also because it was in use). Okay, I thought, I’ll just restart and see what happens.

And now my brand new $1800 computer is completely bricked.

The Apple logo appears, followed briefly by the start of the progress bar – and then I hear this whooshing sound, like ocean surf or a heavy breath, and it turns back off again… and then the Apple logo appears again and the same thing happened. Over and over on an endless cycle, just Apple and whoosh. I can sometimes get it to turn off by holding the power button, but turning it back on just gives me the endless cycle and whooshing again; I can’t get into Recovery mode. In the old days I would have tried sticking a paper clip in or some other option for a hard reboot, but there’s nowhere to do that.

Help! How can I get back to a brand-new computer with the old data smoothly migrated?

macos – I set my startup disk to Macintosh HD. But after opening it, the name becomes “/”

Using the System Preference -> Startup Disk I set my startup disk to Macintosh HD. When I open it the name at the top of its window is “/”. When I open the startup disk using Applescript it opens Macintosh HD, but the name of it becomes “/”. Is this normal behavior? My actual applescript code is this.

  tell application "Finder" to open startup disk    
  tell application "Finder" to get the index of Finder window "Macintosh HD"

But the 2nd line produces the error message

error “Finder got an error: Can’t get Finder window “Macintosh HD”.” number -1728 from Finder
window “Macintosh HD”

if I replace 2nd line with:

tell application "Finder" to get the index of Finder window "/"

It gives me the expected answer of 1.

The image below shows the window Macintosh HD. Notice the name at the top of the window and the name at the bottom of the window. Can someone tell me if this is normal or do i have a problem?

Clonezilla Macintosh

Is it possible to boot clonezilla from a USB stick to clone a HDD to a SDD (Mac 7,1)

The goal is to upgrade the HDD to a SDD.

hard drive – Backup fails because duplicate disks ‘Macintosh HD’?? How do I fix this?

I was having some issues (that I also didn’t understand, something about backup drive has changed name), that started happening with backups failing, so I decided to just reformat the external backup drive since I’m at a place where that is low risk. And now backups fail saying Two of the disks to be backed up have the same name saying I have two disks named Macintosh HD. This was working until a few weeks ago, and this a completely ordinary 13″ 2019 MBP.

Duplicate disks Macintosh HD

AFAICT I do not have two volumes named ‘Macintosh HD’ – here is disk utility,

microphone – Can I use a Shure Beta 58 vocal mic with my PowerBook MacIntosh laptop?

I have an older Shure Beta 58 mic purchased in 1996 that I would like to use as an external microphone in lieu of th built in mic on my PowerBook laptop. What interface do I need? I would like to use it for conferencing software like Zoom. I am also supposed to make an audio recording of some songs to send to a virtual choir project.
