hard drive – Macbook Air 2015 wont log in after updating

I’ve just wanter to do some software updates on my 2015 Macbook Air, but that did not go well. during the installation proces I got an error that said “error with installation” this was while it was in the installation manager. The laptop shut down and has not worked since.. When I turn on the computer normaly I get promted tot the normal login screen, when I log in it loads and then I get an black screen with a white stop sign (circle with / in the middle).

I have tried several things:

  1. Boot into safe mode
    When I doe this and log in it goed into the installation manager again and I get the same error as before)

  2. Boot into recovery mode
    When I boot into recovery mode I get to the screen that says “Of wich user do you know the password” and the option of the two users I have to log in. I then try to log in into the main account but it keeps saying the password is wrong (while I type in the correct password). I’ve tried to log into the other user but same problem)

  3. Boot into single user mode to fix the drive
    When I type in /sbin/fsck -y I get the error that there alredy is a drive mounted and therefor it cant perform the repairs on the disc.

I was so clever to not make a back up of my data, so is there an option to acces my data and put it on a external hard drive or to fix the macbook so I can use it again? Would a clean install from usb of maybe catalina or yosemite work without losing my data?

hard drive – Which washers fit the screws in a PC case?

I’m building a case to be extra quiet and would like to add washers to the case and drive screws. As I understand it, washers made of silicone, neoprene, rubber, etc. can assist with vibrations and dampen case noise slightly. There are a few types of screws in a case. To find washers for them my question is: what sized washers go with what sized screws, or what is the name for these washers?

usa – Can I drive on my foreign license in California on an F-1 OPT status?

So, I paid my tuition in Massachussets and I’m currently working on my F-1 OPT in California(my final year). Can I drive here on my foreign license? Do I really qualify as a California resident given I don’t have exact benefits extended to me as that of a resident, I don’t vote or own property here.

I’ve seen rental cars companies not checking for this requirement when we rent cars. I’ve also heard of my friend leasing my car on her foreign license.

javascript – List sub-folders and its ID in the given path in Google Drive with Google App Script

I am trying to create a doc file which contains the list of folders in a given folder path. The Main function is the entry point.

// This function performs the operation of creating the file of the list of folders in the specific folder.
// Usage: Set the ListDocName, the ListDocFullPath, and the SpecificFolder, then just run Main function.
function Main() {
  // Set Doc (output) file name
  var ListDocName = "RootFolderList";
  // Set Doc (output) file path
  var ListDocFullPath = "/";
  // Set specific folder, and this program would list its subfolders to Doc file.
  var SpecificFolder = "/";
  CreateGoogleDocInSpecificFolder(ListDocName, ListDocFullPath);
  var DocFiles = GoogleDocsInSpecificFolder(ListDocName, ListDocFullPath);
    var docFile = DocFiles.next();
    var docID = docFile.getId();
    var doc = DocumentApp.openById(docID);
    var Folders = FoldersInSpecificFolder(SpecificFolder);
      var Folder = Folders.next();
      // Access the body of the document, then add a paragraph.
      doc.getBody().appendParagraph(SpecificFolder + "https://codereview.stackexchange.com/" + Folder.getName() + 't' + Folder.getId());

// FoldersInSpecificFolder function would return a FileIterator
function FoldersInSpecificFolder(FolderFullPath)
  if(FolderFullPath == "https://codereview.stackexchange.com/")
    // Return the FolderIterator in Root.
    return getFolder(FolderFullPath);
    // getFolder return the FolderIterator
    var TargetFolders = getFolder(FolderFullPath);
    while (TargetFolders.hasNext())
      var folder = TargetFolders.next();
      return folder.getFolders();

// GoogleDocsInSpecificFolder function would return a FileIterator
function GoogleDocsInSpecificFolder(docName, FolderFullPath)
  if(FolderFullPath == "https://codereview.stackexchange.com/")
    // Read files in Root, getFilesByName return the FileIterator
    var RootDocs = DriveApp.getRootFolder().getFilesByName(docName);
    return RootDocs;
    // getFolder return the FolderIterator
    var TargetFolders = getFolder(FolderFullPath);   
    while (TargetFolders.hasNext())
      var folder = TargetFolders.next();
      var docFiles = folder.getFilesByName(docName);
      return docFiles;

function CreateGoogleDocInSpecificFolder(docName, FolderFullPath)
  var docID;

    // Create a new Google Doc in Root
    var docRoot = DocumentApp.create(docName);

    return docRootID;
    // Create a new Google Doc in Root
    var docRoot = DocumentApp.create(docName);

    // Get new Google Doc file ID (Use in copy)
    var docRootFile = DriveApp.getFileById(docRootID);
    var TargetFolders = getFolder(FolderFullPath);   
    while (TargetFolders.hasNext())
      var folder = TargetFolders.next();
      // Copy Google Doc to correct file path
      var docFile = docRootFile.makeCopy(docName, folder);
      docID = docFile.getId();
    // Delete Google Doc in Root
    return docID;

// getFolder function would return the FolderIterator which is locate at Path.
function getFolder(Path)
  var SubFolder;
  var arr = Path.split("/");
  for (var i = 1; i < arr.length; i = i + 1)
    var FolderName = arr(i);
    if(i == 1)
      SubFolder = DriveApp.getRootFolder().searchFolders("title contains '"+FolderName+"'");
      if (SubFolder.hasNext())
        var folderTemp = SubFolder.next();
        SubFolder = folderTemp.searchFolders("title contains '"+FolderName+"'");
  return SubFolder;

disk utility – How to use internal HDD as a file sharing drive if I boot from external SSD on mac mini?

I’m running Mojave 10.14.6 on mac mini late 2014.

It has internal hdd drive. I bought an external ssd to speed things up and run everything from it, and use internal hdd as a data storagetime machine

I installed OS on ssd and am running the mac from it, but I can’t seem to erase the internal hdd drive. When trying to partition it in Disk utility I’m getting an error

The volume “osx” on disk1s1 couldn’t be unmounted because it is in use by process 82 (securityd)

After this error happened, disk utility shows that hdd has two partitions, 500gb each (that’s how I set it up on ‘partitioning’ step), but I can see only the partition that was there before, no new partition that I added. Might sound confusing – please see the screenshots here.

Now, I’m very sure that I run OS from external SSD, so I don’t understand why any process would use internal hdd and what should I do from now on.

So the question is, how do I use internal hdd as a data storage drive, and erase the OS from it?

Can a publicly shared file stored in my Google Drive be deleted by someone having “Anyone with the link” editor rights?

Short answer. No.
None of the editors having “Anyone with the link” editor rights can delete the file.
The only person who can delete this file is the owner of the file.

You can see that when changing the sharing permissions of a file to Anyone with the link can Edit, the option of changing the settings is greyed out with the message Settings are disabled for public links

enter image description here

Furthermore, when within the file Edit menu , the option of moving the file is greyed out as well.

enter image description here

One can only use the Add a shortcut to Drive.
Even if one later decides to delete this created shortcut from the drive, the original file remains intact.

You can safely, publicly share, any file stored in your Google Drive using “Anyone with the link” editor rights.
Your publicly shared file will never be deleted by anyone else but you.

Important Note
Please do NOT confuse the above with editors added under Share with people and groups.
They CAN delete the file and even deprive you of your rights as the owner.

hard drive – Can I Get Firmware For My New HDD?

I have another question. I have yet ANOTHER issue with my iMac. When the late 2009 iMac came out, replaced the internal hdd would make the fans go at full blast. I removed my Seagate ST3500418AS (because it died) and replaced it with a Toshiba DT01ACA050. There were no visible temp. sensors when my dad and I replaced it. The machine was quiet and functional, until it started to run at full blast. The Toshiba HDD previously had Linux Mint, so I thought it was a compatibility issue- that is, until I install macOS X. The hard drive fan is running at full blast! I know I can control the speed with software, but I want to make it so the fans are always quiet (I dualboot macOS and Linux). They (Apple) started programming the drives with temperature sensor firmware. I would like to know how I might be able to get firmware to fix my Mac. I have another drive shipping in later this week, so I will try that, but it will probably be the same issue. How can I fix this? Thanks!
