Jan 07, 2020 I use Mac Mail for emails, synced with an Exchange account. Ever since the Catalina upgrade, when I move an email from the inbox to other folders, or when I try to delete them, the Mail app gets stuck in 'moving messages' and so I would see the movement or deletion of the message locally, but it will not make the change in the server and the change will not sync to my other devices. Nov 13, 2020 Go to Mac App Store and open updates. If your Mac install stuck on Apple logo, gray/white/black screen when you were installing an App, you can go to Mac App Store to find this app and open the updates to survive from the macOS installation stuck situation. Download & install the combo update.
The below is taken from https://www.maketecheasier.com/fix-frozen-mac-when-updating-macos.
- Restart your Mac. Whenever you encounter the boot problem, you can try rebooting Mac.
- Nov 01, 2018 Hold down the power button for 10-15 seconds to fully shutdown your Mac. Disconnect all external devices such as USB drives, printers, docks, etc. If you're not using a Macbook, you can keep your keyboard and mouse plugged in. Now power on your Mac and if it starts successfully then it is one of your peripheral devices.
1. Install the Update in Safe Mode
If it's clear that your Mac update isn't going anywhere, then hold down the power button to turn off your Mac. Once you've done this, boot your Mac into Safe Mode. There are several ways to do this, but the simplest is by holding the Shift key as it's booting.
The Apple logo should appear on your screen with a loading bar, and after that you should boot into Safe Mode. From here, run the macOS update as you normally would to install the update – hopefully without a hitch.
2. Check the Apple Systems Status Page
A very quick and easy thing to do that could save you a lot of hassle with stuck updates (or other malfunctioning Apple services) is to go to the official Systems Status page. Here you'll see the status of just about every Apple service you can think of. Look over at the status of 'macOS Software Update' to see whether the update servers are working as they should. If the bubble is green, then they're fine and the issue lies elsewhere. If it's red or yellow, then you're just going to have to sit out the problem until servers are back to normal.
Speaking of sitting it out…
3. Sit it Out
As painful as it sounds, you may just want to let the Mac sit for a couple of hours and see if it is indeed frozen. Sometimes, the update could be stuck in a lull but not completely frozen. Some update processes will take much longer than others, resulting in a seemingly stuck progress bar.
We can verify that the system is still updating by pressing Command + L to bring up the estimated install time. If this doesn't appear, still let the update sit for a while.
Some users have reported their update taking upwards of ten hours. Grab a coffee, do some other work, run some errands, do whatever you need to do to burn some time and let your Mac do its thing. Big system updates (sometimes) take a whole lot of time!
4. Refresh the Update
If you are positive that the install is indeed frozen, you will want to take the following steps, and the following steps consecutively after this step, until the issue is resolved.
Let's try to give the install a little kick by refreshing it.
- Hold down the power button and wait for about 30 seconds.
- When the Mac is completely off, press and hold the power button again. Now, the update should resume.
- Press Command + L again to see if macOS is still installing.
If there is no avail, continue onto the next solution below.
5. Reset Your NVRAM
NVRAM, as Apple describes it, is 'a small amount of your computer's memory that stores certain settings in a location that macOS can access quickly.' It also happens to hold kernel panic information, which is what we're tapping into and especially trying to reset here.
- Press and hold the power button on your Mac to completely shut it off. Hard discs and fans need to stop spinning, and the screen needs to go dark.
- Power on your Mac.
- Immediately after you hear the startup sound, press and hold the Command + Option + P + R keys.
- Keep holding them down until you hear the start up sound again.
- Release the keys, and the NVRAM will have reset. The update should resume.
You have encountered a severe problem. That is your Mac stuck on the loading screen for a long time, usually after a recent macOS like macOS Big Sur update or macOS reinstallation.
You may regard such a long boot process as a slow startup of your Mac and wait for hours. But the sluggish progress bar still remains on the screen without any change.
In fact, your Mac won't turn on at all and froze on startup. All the documents, photos, videos, etc. on Mac are in danger of loss. Rescuing data from your Mac is a primary task before fixing the issue - Mac stuck on the loading screen with Apple logo on startup.

Solution 1: Restart your Mac
Whenever you encounter the boot problem, you can try rebooting Mac. This way is easy and sometimes works.
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.
After a few minutes, press the power button to restart the Mac again.
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.
To boot your Apple M1 Mac like M1 iMac into Safe Mode:
- 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
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
Mac Os Download
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. Reset SMC when MacBook Air and MacBook Pro stuck on loading screen
- 1. Force shut down the Mac that is frozen on loading screen.
- 2. Press Shift + Control + Option on your keyboard and press the power button at the same time.
- 3. Hold these keys for 10 seconds and then release the keys.
- 4. Press the power button again to turn on your Mac.
2. Reset SMC when Mac Mini, Mac Pro and iMac stuck on loading screen
- 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.
Solution 5: Repair startup disk in macOS Recovery mode
Sometimes, the Mac stuck on the progress bar because the startup disk is corrupted. Fortunately, you can use First Aid, a built-in disk repair tool on your Mac, to fix the errors on the startup disk that cause the Mac stuck on the Apple logo with a loading bar.
Firstly, boot your Mac into macOS Recovery mode:
- Press and hold the Command + R keys when rebooting your Mac.
- Release the keys until you see a spinning globe or Apple logo on screen.
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.
After data recovery, you can proceed with reformatting the Mac hard drive.
1. Reformat the corrupted startup drive
- 1. Restart your Mac into macOS Recovery mode.
- 2. Select Disk Utility from the macOS Utilities menu and click Continue.
- 3. Select the Mac hard drive (often named Macintosh HD or Apple SSD) from the left sidebar.
- 4. After clicking Erase on the top, you need to name it as Macintosh HD, and then give it a scheme and format.
- 5. Click Erase to confirm this operation, and then wait it to complete.
Now, you have an empty but workable Mac hard drive.
2. Reinstall macOS in macOS Recovery mode
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
Mac Os Versions
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.

Why is my Mac stuck on loading screen?
Curious about the reasons why your Mac not loading? Go on reading to get the answers.
Normally, Mac would show the Apple logo at startup once it finds your local startup disk. Then, based on if you have encrypted the startup disk, a loading bar appears after or before you log into the Mac.
The Mac progress bar indicates that the system is checking and loading macOS from the startup disk. It involves macOS structure, corn components, file system, etc.
However, if something is not going well, like the corruption of the startup disk file system, your Mac will stick on startup.
