I have tried disk repair which gives error 8 so I booted to Single user mode but the command prompt is on the recovery partition dev/disk2s1 not Macintosh HD, how do i change to dev/disk1s1. so i can run fsck -fy

Holding shift on boot only shows recovery drive.

In Terminal cd is used to change directory.

When you’re in the Finder and you want to move to another folder, you find that folder and double-click it. From the command line, you use the cd (or change directory) command instead. So let’s say you’re in your Home folder and want to peek inside the Downloads folder. To do that, you’d type cd Downloads. (Remember to always type a space after any command that has an additional argument, such as the name of a directory in the previous example.) Once you’ve done that, ls will show you the contents of your Downloads folder.

Here are a couple of quick tricks for moving around in your Mac’s file system.

If you type cd and press the Return key—with no directory specified—you’ll go back to your Home folder. (You can also type cd

If you type cd /, you’ll go to the root level of your startup disk.

If you type cd .. (that’s two periods), you’ll go to the directory above the one you’re currently in. So if you’re in your home folder, and type cd . you’ll go to your Mac’s /Users folder.

And if you type cd — (hyphen) you’ll go back to the directory you were in before the last time you issued the cd command.

That should be enough to get you started. Try playing around in Terminal, exploring your folders and files with just those two commands. In future articles, I’ll show you how you can apply the ls and cd commands in more depth, so you can be comfortable flitting around your file system from the command line.

Question: Q: What Causes «The operation couldn’t be completed. Undefined error: 0» Big Sur Defect?

A problem seems to exist with Big Sur Finder that can be discreetly identified when attempting to compress an application. The issue with the compression is not the actual problem but rather a symptom. When an application cannot be compressed and yields the following error:

(«The operation couldn’t be completed. Undefined error: 0»)

If this occurs, then a number of other Finder defect symptoms can be observed related to the given app. This is not a question about how to work around this defect in Big Sur, it is a question of «what causes this» and «can the macOS defect be avoided or fixed».

Some applications on Big Sur do not exhibit this issue, some do. The problem does not seem to be related to apps download from the web or from the App Store as it has occurred to apps that are sourced from both. (FinderMinder, open internet source. Apple Numbers, Pages, Keynote, App Store sourced).

The only way I have found to work around this is to obtain a copy of the app from some source that is not related to a macOS Big Sur storage volume. Unfortunately the problem seems to come back. I am not aware of any fix short of not using Big Sur. This problem occurred in the first release of Big Sur and is still occurring in 11.1. The applications were all present on the hard drive prior to loading Big Sur which suggests that the problem was created at the time of installation or after the launch of the file management system aka Finder.

The symptoms below relate to actions taken from a host MacBook Pro Touch Bar running Big Sur unless otherwise noted. When an application compression fails on the host, the other symptoms can be observed as noted. When an application does not fail to compress, the application then can be copied, moved, drug-dropped as expected and exhibit no errant symptoms.

Symptoms

Key:

Finder compress fails producing «The operation couldn’t be completed. Undefined error: 0»

Then:

1. Drag through Screen Sharing to copy to another machine always fails
2. Drag through Apple Remote Access (ARD) to another machine always fails.
3. Copy app from local HD to Apple File Protocol (AFP) server volume always works
4. Copy app from local HD to Server Message Block (SMB) file server volume fails
   1. Copy text file to same SMB volume works
5. Copy app to AFP volume, then to SMB volume from AFP volume will sometimes partially fails producing a corrupt app at the destination, other times just failing indicating «Items can’t be copied to “Sharing” because you don’t have permission to read them.»
6. Deleting the partially failed copy fails with «The operation can’t be completed because the item “FolderColorizer” is in use.»
7. Drag the copy from AFP server volume through Screen Sharing or ARD to another machine always fails the same way as #2
8. Compressing copy on AFP server sometimes works, sometimes fails the same as «Key»
9. Dragging compressed copy from server volume to anywhere else noted above with any mechanism always works
10. Decompressing the copy using any machine other than the source machinealways fails with «Unable to expand «[appName]» into «[folderName]». (Error 1 — Operation not permitted.)
11. Decompressing the copy on the original (MacBook) will produced a corrupted copy of the app

Homebrew error in OS X. Bad interpreter: Too Many levels of symbolic links. Undefined error: 0

I’ve been searching for an answer to this problem for a few weeks now, and while I’ve seen similar problems, none that I have found have been exactly like the error I’m experiencing. I’ve tried uninstalling and reinstalling Homebrew to no avail. I’m not the most experienced user in the world of bash scripting and the command line in general, so be gentle with me.

I’m running Mac OS X 10.10.1 Yosemite.

Anyway, whenever I try to run a brew command, I get the following error-

I opened the usr/local/bin/brew file and it looks just like a copy of the error I’m seeing —

The other thing is, I’m finding something that doesn’t seem right to me (but I could be wrong) in the /System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby folders.

First off, when clicking on ruby.framework/Versions the contents are an alias for 1.8 (is this supposed to be there if 2.0 is the default installed with os x 10.10? The alias also says it can’t find the original item), a 2.0 folder, and a «Current’ alias that when clicked on says the original item can not be found also. Inside the 2.0 folder, the «Current» alias there also can’t find the original item.

Is any of this off, and could it have anything to do with why I’m getting the Homebrew error? This could be extremely simple and I just have to delete a line from a file, or it could be larger and involve the potential problems I found above. Any help would be greatly appreciated. I have some things I need to install this week, so I’m trying everything I can to figure and solve this. I’ll give you any information you need in order to assist you in helping me.
