Stuck In The Dark Mac OS

This happens because Mac OS VMs have a non-generic property. This property is only for Mac OS VMs. After Restoring the VM, if this property is not found, then, the VM wouldn’t boot up. In this guide, we will look at some of the installation problems that tend to occur with new releases of the Mac operating system. With any luck, you may be able to either correct the issue, allowing you to finish the installation, or prevent the problem from occurring in the first place. After that, you will see another window, Name and operating system, for that you need to type the name of Virtual machine. As I have typed macOS 10.14 Mojave and select the Machine folder. I recommend you to select Drive C for installation. When you are typing Mac automatically the Type for macOS will select and Version Mac OS X (64-Bit). Dark mode was introduced with macOS Mojave (10.14) and released in the fall of 2018. Macs using older versions of macOS or OS X like High Sierra and Sierra are unfortunately not able to use dark mode but can enable a dark menu bar and dock. Enabling or disabling dark mode can be done via the Mac.

When your Mac, like MacBook Pro, is stuck on loading screen, you can press and hold the power button for a few seconds to turn off the Mac. Then, disconnect all peripheral devices from your Mac. This will isolate the problem caused by peripheral devices and leave the Mac alone.

Solution 2: Boot your Mac in Safe Mode

Mac stuck on Apple logo with loading bar could be caused by software conflict or incompatibility. So, to confirm it, you can boot the Mac into Safe Mode.

A safe boot will prevent your Mac from launching unnecessary programs and login items at startup. It also does a basic check of your startup disk and may solve the slow startup issue of your Mac.

To boot your Intel-based Mac into Safe Mode:

1. Force your Mac to shut down.
2. Press and hold the Shift key while tapping the power button to start your computer.
3. Release the Shift key until you see the Apple logo and loading screen.

1. Shut down your Mac and wait for seconds.
2. Press and hold the power button until the startup disks and Options appear on the screen.
3. Press and hold the Shift key, then click Continue in Safe Mode.

If your Mac boots past the loading bar and enter Safe Mode successfully, it's surely the software or firmware conflict. Find out the conflicting program or software, usually the recently installed third-party software, and then uninstall it.

Next, you can simply reboot your Mac and find that the Mac stuck on the loading bar issue is fixed.

Solution 3: Reset NVRAM/PRAM

Mac Os Dark Mode

PRAM or NVRAM is a non-volatile random access memory. It is used to store system settings on Mac, including startup disk selection and recent kernel panic information. So, when Mac won't boot after macOS update but Mac progress bar stuck at 100%, resetting NVRAM/PRAM might help.

To reset NVRAM/PRAM, you can simply restart your Mac and simultaneously press Command + Option+ P + R keys. If you have an M1 Mac, you don't need to reset NVRAM. Because it is automatically run test and reset on startup if needed.

Solution 4: Reset the SMC

SMC (System Management Controller) is used to control a number of Mac core functions, including sudden motion sensor and thermal management. Typically, when Mac freezes on startup or stuck on loading bar, SMC reset helps to resolve such unresponsive issues related to power and hardware.

To reset the SMC on a Mac computer stops loading halfway, follow the way below. Note that there is no SMC on M1 Mac.

1. Shut down your Mac and then unplug a power cord.
3. Wait 15 seconds. Then, plug the power cord in.
5. Wait several seconds and turn on your computer by pressing the power button.

After booting into Mac Recovery mode, choose Disk Utility. Select the startup disk and click First Aid in the Disk Utility window. Next, click Run to check and repair the startup disk.

If First Aid successfully found the errors and repaired them, you can restart your Mac quickly without a slow startup. Disk Utility helps Mac boot up, and your Mac desktop or MacBook won't be frozen on the startup screen this time.

Solution 6: Reformat the startup disk and reinstall macOS

If you can't fix the Mac that stuck on the loading screen with First Aid, the startup disk is critically corrupted. In this case, you need to erase the startup disk in macOS Recovery mode. Disk erasure will reformat the hard drive with a new file system. And then, you can reinstall the macOS.

This usually will fix this issue. However, disk erasure will wipe all your files off the drive. So, if you have important files on this Mac, you should first rescue data from the Mac that stuck on the loading bar. It's necessary especially if you don't have any backup.

5. Click Erase to confirm this operation, and then wait it to complete.

Now, you have an empty but workable Mac hard drive.

After erasing the Mac internal hard drive, you can continue to reinstall a new macOS in macOS Recovery mode. Click the Reinstall macOS utility in macOS Recovery mode and then follow the instructions to reinstall the operating system.

Hopefully, it fixes the Mac that stuck on the progress bar at startup.

Solution 7: Downgrade macOS

It's inevitable that a macOS update is not compatible with your Machine. For example, your Mac stuck on the Apple logo when you proceed or finish the macOS Big Sur update. The updated macOS Big Sur software is not compatible with MacBook Air before 2013.

To make the Mac boot past the progress bar and won't stick on the loading screen anymore, you can revert it to the previous state. In other words, just downgrade the macOS. Downgrading macOS may erase your hard drive, so you also need to back up data on the unbootable Mac first.
