Why Doesnt My Macbook Air Show The New Update To Download For Mojave

Update: It's also worth noting that the upcoming watchOS 5 will be the first version of Apple's Watch operating system that won't work on the first-generation Series 0 model. And yes, that's true.

  • Two years ago I did an udate on my macbook and the computer stopped working. It would not boot and I took it to a computer store who told me that it might be a problem with the motherboard. I then got a new macbook pro which worked perfectly until yesterday. I did an upgrade, unfortunately I did not look what it was, just proceed to install it.
  • If you don’t have Mojave supported Mac, you can download the Mojave Installer App using patcher tool. Open the macOS Mojave patcher tool. If it doesn’t open and says it is from an unidentified developer, right click on the tool’s icon and click on “Open” from sub-menu and then enter your Mac’s Admin name and password.
  • Why won't macOS Catalina install on my Mac? Posted by: Jailbreak - How To, Mac OS, MacOS, macOS Catalina Contrary to Apple's promises to ensure the most stable operation of macOS Catalina on all compatible devices, regardless of generation, only a day after the release of the update on the Web, there were a lot of complaints about the.

Summary: This page helps you login to your MacBook Pro, MacBook Air, iMac, Mac mini. It fixes 'Mac stuck on the login screen' issue after (or before) entering the right password.

Admittedly, Mac computers are powerful and reliable. But macOS is not immune to errors and corruption. Many users have reported the same problem: Mac stuck on a login screen.

Chances are that Mac won't let you log in with right password. Or you can't enter the password at all because the Mac freezes at login screen and the mouse won't move. Most of the time a force reboot might fix the problem, but it might be worse if the Mac computer won't boot after the latest macOS update.

In this post, you can unfrozen the iMac or MacBook from the login screen by:

  • Disabling Login items at startup
  • Booting into Safe and Verbose Mode
  • Resetting NVRAM/PRAM
  • Troubleshooting Mac in macOS Recovery mode
  • Reinstalling macOS

Two situations your Mac gets stuck on login screen

Before you go further, you should know there are two kinds of Mac OS X signin problems. It depends on if you have enabled FileVault to encrypt your startup drive.

1. Mac won't load past login screen after entering password

It happens to users who encrypt the system drive. You'll be asked for a password before you see the progress bar. In this case, the password is usually accepted, but Mac is stuck on the loading bar. The loading bar may stop somewhere between 50% and 75%, or even 100%.

You can't login to your Mac in this situation because of a Kernel program incompatibility, file system corruption, or some core data lost.

2. Mac won't accept password or you can't enter password in sign in screen

Another case is that the startup is not encrypted by FileVault or APFS feature. Assuming that you use a MacBook Pro, you'll see the loading bar first. But the MacBook Pro's login screen may not appear or gets stuck. MacBook Pro won't accept password but freezes with a spinning wheel or you are unable to type in password.

This MacBook login problem is usually caused by software conflicts, frozen software, or configuration errors.

What to do when Mac stuck on login screen?

Anyhow, these methods would help Mac boot past frozen login screen.

Solution 1: Bypass Login items at startup

In some cases, it's software that stops you from getting to your Mac. Then, you can try these steps to sign in your iMac or MacBook.

  1. Start your MacBook normally.
  2. On the sign in page, enter the admin account and password if you can, but DON'T click on Log in immediately (in case of a login loop).
  3. Press and hold the Shift key to stop frozen apps launching. And then, you can click on the Login button.

Solution 2: Boot your Mac in Safe Mode

Booting Mac into Safe Mode will only launch necessary programs. It's efficient to isolate incompatible software and repair some errors when Mac login window not responding.

To boot into Safe Mode:

  1. Press and hold the Shift key while tapping the power button to restart your Mac.
  2. Release the Shift key till you see the Apple logo and loading bar.
  3. If your Mac loads successfully in Safe Mode, try to uncheck login items in Users & Groups.

Sometimes Apple computer won't let you login to Safe Mode because FileVault is enabled. You could decrypt your startup drive temporarily by booting Password Reset Assistant. This makes Safe Mode be able to check and repair errors before the login window appears.

If you succeed in turning off FileVault, you can restart your Mac normally. Then you can see if it brings up the login window. But if the progress bar is stuck underneath the Apple icon, you can try Safe Mode again after turning off the FileVault.

Solution 3: Reset NVRAM / PRAM

NVRAM, as well as PRAM, is a small amount of memory that your Mac uses to store certain settings and access them quickly. Thus, whenever your Mac won't boot, you can try to reset the NVRAM / PRAM.

Now, restart your Mac and simultaneously press Command + Option + P + R keys for about 20 seconds until your Mac restart automatically.

Solution 4: Boot your Mac into macOS Recovery mode

Mac could freeze on the login screen in a normal boot. But if you can boot into macOS Recovery Mode, you could troubleshoot this issue more easily. Recovery mode, sometimes called sigle-user mode, is a lite built-in macOS utility to check and repair some system issues.

To boot into macOS Recovery Mode:

  1. Press and hold the power button until the Mac turns off.
  2. Restart the Mac and immediately press and hold the Command and R keys.
  3. Release those keys when you see the loading bar.

If you successfully boot into macOS Recovery Mode, you'll see a macOS Utilities screen. (In some old system, it's called Mac OS X Utilities.) Then, you can do several things to fix the Mac stuck on login screen issue.

1. Repair the startup drive in Disk Utility

Probably, the Mac won't past the Apple logo or login screen because of file system or disk errors. Fortunately, you can check for and repair errors with the built-in tool First Aid.

2. Reset password

Mac could be stuck on the login screen after you forget the Mac's password. If you've entered the wrong password too many times, the system could be locked. Then the Mac won't accept the password even it's the right one.

In this case, you may want to reset your Mac's login password by:

  1. 1. Entering your Apple ID
  2. 2. Providing recovery key if you have created on before.

You can also do this via Terminal.

  1. 1. In macOS Recovery mode, open the Terminal by clicking Utilities > Terminal in the top menu bar.
  2. 2. At the Terminal prompt, type resetpassword, and then hit Enter.
  3. 3. Follow its onscreen wizard to reset the password.

With the password hint, you can change the password of a non-encrypted account. Then you can restart your Mac and log in to your Mac again.

3. Check and fix user preference settings

Sometimes, the .plist files related to user preferences could be changed. Then, your login information would not be accepted.

In this case, you can use the mv command in Terminal to rename the preference folder. And you can troubleshoot and nuke the problematic .plist file easily.

The other times you can't log in to the Mac just because the access to the user directory was changed. You can run chmod to change the access permission.

4. Reset launch services database

If the Mac gets stuck on the login screen and won't accept the password, you can remove the .csstore file ( a launch services database) in Terminal and fix the problem.

  1. 1. Open Terminal in macOS Recovery mode.
  2. 2. At the Terminal prompt, type find /private/var/folders grep com.apple.LaunchServices grep csstore, and then hit Enter.
  3. 3. Remove every .csstore file you can find by rm command.

Hopefully, you can log in to your Mac after a rebooting.

5. Reinstall macOS in macOS Recovery mode

If you are not one of the situations above but see a folder with question mark on the Mac, you can simply reinstall the macOS to reset your Mac.

This will be helpful especially if you need to downgrade from a recent macOS Big Sur update to macOS Catalina.

How to prevent data loss when you can't log into the Mac?

Probably, you have tried out all the solutions above, but the Mac keeps getting stuck on login screen. Then, you might want to erase your disk to reinstall macOS.

Before heading to erase the Mac hard drive, please make sure you have backed up your data. If you don't have backups, you can use Mac data recovery software like iBoysoft Data Recovery for Mac. It would be helpful to recover lost data from the unbootable Mac.

To recover data from unbootable Mac, you need to run iBoysoft Data Recovery in macOS recovery mode.

Summary: This post is about how to fix when Mac won't boot after macOS update. If macOS Big Sur or macOS Catalina update makes your Mac not booting up, you'll know why and how to fix it quickly and easily.

Apple releases macOS and software updates periodically for better user experience. However, it backfires when your Mac won't boot after macOS update. Especially for some Mac newbies, Mac not turning on would drive them crazy.

Hence, this post will walk you through this problem. Then, you'll know what to do when Mac gets stuck on the Apple logo.

All right. Let's begin with why your Mac is not booting up after the macOS update.

Why is the Mac not turning on after macOS update?

Why won't Mac update successfully? It's fair enough to say, most of the time, Mac won't turn on after macOS update because of software incompatibility and bugs.

As we all know, technology inspires new programs and hardware to be released constantly. So, your Mac needs to update to work with most software and hardware. Sometimes, it's an overall macOS update. And sometimes, it's a tiny patch like this.

In detail, a macOS update could involve those activities.

  1. Upgrade certain necessary drivers. Sometimes, it simply installs patches to fix bugs. But sometimes, it will replace the whole driver structure to better use hard drives, keyboard, mouse, microphone, camera, etc.
  2. Upgrade the Kernel programs. Such updates will improve the security, accessibility, and management of core data.
  3. Redesign or update certain built-in applications. Utilities like Disk Utility, Safari, and Mail come along with the operating system. So, it could be updated for a better user experience.
  4. Other updates like operating system structure, file system, user interface, etc.

These updates are usually for a better user experience. Or they are for better supporting most of the latest hardware and software. However, as it is pointed out, the updated macOS can only work 'most' of them.

For example, Nvidia GTX 750 Ti can't work with Mac OS X earlier than Yosemite. After such a software update, Mac is not worknig, or the Mac or MacBook gets stuck on a loading bar after update. Once the third-party software and hardware on your Mac won't work with the latest macOS, your Mac won't turn on.

Common boot problems after macOS update

macOS is an improved range of Mac operating systems after Mac OS X. Up to now, there are three macOS systems available: macOS High Sierra, macOS Mojave, and macOS Catalina. Nevertheless, updating to each of them could cause problems.

1. Mac won't turn on after macOS Big Sur update

The newest major release of Mac operating system is macOS 11 Big Sur, which now is in beta version. Up to now, known boot issues of macOS Big Sur Beta include the following, or more.

  • If you updated to macOS Big Sur 11.0 but not the newest vesion that has fixed existing bugs.
  • You choose a wrong startup disk after installing macOS Big Sur 11.

2. Mac won't boot after macOS Catalina update

Then it comes to macOS Catalina. Even though it should be better than the previous two, (In some aspects, it is.) Catalina update problems like Mac won't boot after macOS update still occur.

Except for APFS conversion, the macOS Catalina update will automatically divide your hard drive into two volumes. One is the read-only Macintosh HD system volume, and the other is Macintosh HD - Data for saving your files. But if there is not enough free space for an update, your Mac will get stuck on a update loop.Whta's worse, you might see the Mac folder with question mark at startup because macOS Catalina update is not found.

What's more, the 'Full Disk Access' permission might be a lion in the way for some unauthorized applications. For instance, you have a program that requires certain Kernel extensions. But after updating to macOS Catalina, this program can't access the Kernel resource anymore. It doesn't have permission. As a result, your Mac will be frozen at the loading bar because this program keeps asking for resource permission.

3. Mac won't restart after macOS Mojave update

macOS 10.14 Mojave is coming after 10.13 High Sierra. Thus, the same boot problems on macOS High Sierra could also happen to macOS Mojave. As you might know, Apple introduced the System Integrity Protection (SIP) feature since OS X EI Capitan. It was originally introduced to keep system security. But once this feature was disabled previously before you update to macOS Mojave, it could cause boot problems.

For example, the Google software update on September 23, 2019, was shipped with a bug. This flaw damages the macOS file system on computers where System Integrity Protection is disabled. Many video professionals reported that their Mac crashed due to this.

So, just think about it, even Google can't avoid such software conflict, how about other third-party software? That's one of the reasons why many users who disabled SIP previously get Mac crashed after installing macOS Mojave.

4. Mac won't boot after macOS High Sierra update

One of the major updates in macOS High Sierra is the introduction of the Apple File System (APFS). As a part of the upgrade process, the macOS High Sierra installer will automatically convert the SSD to the APFS file system.

Even though Apple claims that the conversion process is supposed to be risk-free, many Mac users still meet problems. And disk corruption during the update is one of them. In this case, it's sure that the Mac won't restart after update. Mac will stop loading after update for such corruption.

Except for hard drive corruption, hardware or software incompatibility is another major reason. As your computer needs to work with so much hardware and software, the in-between conflict is inevitable. Those incompatibilities could slow your Mac down. They could make your Mac not responsive. Or, the Mac won't let you log in with right password. Also, the Mac could freeze on a black or Mac white screen of death.

What to do if Mac can't turn on after macOS update?

Having discussed why Mac won't boot after macOS update, you may find that it's tricky to hit the point. But don't worry, here are some inspirations so that you can troubleshoot this issue step by step:

  • 1. Check if the Mac hard drive is corrupted
  • 2. Check if any program is not compatible with your macOS
  • 3. Check for a hardware incompatibility

Step 1: Check and repair the Mac hard drive in macOS Recovery mode

If your Mac refuses to boot after the update, you should check the Mac hard drive. Chances are that your MacBook ran out of power and the APFS reformatting process was interrupted. Or the hard drive is corrupted for bad sectors.

In this case, you can try to repair the hard drive with Disk Utility under Recovery Mode. Disk Utility helps Mac boot up in some ways sicne it's the built-in free disk repair tool on your Mac.

If no disk error was found by Disk Utility, then the hard drive should not be responsible for this issue. To find out why you can't turn on your Mac after macOS update, you can try Safe Mode.

Step 2: Boot your Mac into Safe Mode

You may be wondering 'why should I do this in Safe Mode?' The reason is that Safe Mode will only launch some basic necessary programs at startup. It’s easier to isolate incompatibility software that makes your Mac unbootable.

Make sense, right? Then let's dive into details on how to do this.

  • 1. Press and hold the power button until the Mac forcibly shuts down.
  • 2. To start the Mac up in Safe Mode, restart this Mac with Shift key pressed and held.
  • 3. Release the key when you see the progress bar.

If you boot into Safe Mode successfully, you'll see Safe Boot at the right top. At least, it indicates that the macOS update is not failed. Then, it should be third-party software incompatibility.

But to figure out exactly which program makes your Mac unbootable, you need to reboot into Verbose Mode. Verbose mode allows you to see what's happening when macOS is starting up.

You can hold Command + V at startup. Then you'll see a live report when your Mac is booting up. Once you find out the culprit, you can simply uninstall the software in Safe Mode

But if you fail to boot into Safe Mode, it means it's a macOS update failure. The system data is damaged or broken. You need to reinsall the macOS in macOS Recovery mode. You can simply boot into macOS Recovery Mode and choose Reinstall macOS. If you don't want to update macOS anymore, you can try your luck with using APFS snapshot to recover your system.

The point is that macOS reinstallation will risk your data on the Mac. Thus, you should first check your backups. Or you can recover data from unbootable Mac first.

Learn how to get your important files off the startup disk when your Mac won't boot.

Tips: You can prevent APFS conversion with start to install this time if you want to avoid unnecessary problems. But you are not advised to unless you are a Mac command geek.

Step 3: Ask Apple repair store for help

The toughest thing is that your hard drive is fine. And there is no software incompatibility noticed in Verbose Mode. In this case, you should check the hardware inside your Mac.

The reason is that macOS updates are always for better supporting the latest software and hardware. So, the hardware or drivers on your Mac may be too outdated to work with the newer OS.

In this case, you can ask help from the Apple repair store and reset the Mac. If it's the Mac machine itself is too old, you should replace it with a newer Mac model. Or you simply don't allow automatically update the macOS.

How to avoid macOS update failure?

Every time there is a new macOS update available, you'll receive a notification. It asks 'Do you want to restart to install these updates now or try tonight?'. However, it's not safe to update directly because your Mac could get stuck on update or even lose important files. In case the Mac won’t boot after macOS Big Sur or Catalina update, you surely can do some preparations in advance.

  • Read several reviews from tech enthusiasts to learn problems when a new macOS beta is released.
  • Make sure your Mac model and its hardware work with the updated macOS.
  • Read macOS update instructions carefully when you are up to update your system.
  • Back up your files, photos, documents, etc.
  • Make sure there is enough free disk space for macOS update.
  • Make sure your Mac is connected to power to avoid the black screen of death during macOS update.

So, you'd better do these preparations before you update to any operating system. But if your Mac can't boot up already, you should calm down and follow this guide to fix this issue. If you have any more any feasible solution to enrich this article, kindly drop us a hint at [email protected]
