"Solutions to Fix an iMac That Won't Power On"

Are you searching for possible reasons why your iMac won't turn on? The approaches we'll outline depend on the degree of unresponsiveness of your iMac. Those iMacs that have no power at all can often be resolved quite easily, whereas those that show slight responsiveness with fan spinning noises might present more complex issues potentially involving the logic board.

When your iMac won't boot past the Apple logo and remains stuck on the loading screen, you can try the following solutions to resolve the issue without compromising the security of your data.

Method 1: Restart Your iMac

The most straightforward method to restart an iMac involves selecting a few options from the panels available on almost every iMac screen. To reboot your iMac, follow these steps: 1. Click on the Apple logo in the top left corner of the screen. 2. From the drop-down menu, choose "Restart" option. 3. A confirmation prompt may appear, asking if you want to restart now. Click "Restart" again to confirm. 4. Your iMac will begin the shutdown process and then automatically turn back on. If your iMac doesn't respond to the above method, you can try using the physical power button: 1. Press and hold the power button located on the back of the iMac (usually on the lower right side) for about 5-10 seconds. 2. The iMac should shut down. After a few moments, press the power button again to turn it back on. Remember that force restarting might lead to data loss or other issues, so only use this method if the standard restart process fails.

Step 1. Click on the Apple menu located in the top left corner of your iMac screen. Then, select the "Restart" option.

Step 1. Press and hold the power button on your iMac to turn it off completely.

Step 2. Restart your iMac by holding down the "Shift" key.

Step 3. Once you see the loading bar, let go of the Shift key.

Method 3: Force Quit Unresponsive Apps on iMac

Forcing your iMac to close unresponsive applications might resolve the issue of your iMac not turning on. You can forcefully quit Mac applications using keyboard shortcuts, and the steps involved are as follows: 1. Press and hold the Command (⌘) + Option (⌥) + Escape keys simultaneously on your keyboard. 2. A "Force Quit Applications" window will appear, listing all the currently running apps. 3. Select the unresponsive application that you want to force quit from the list. 4. Click the "Force Quit" button, or simply press the Enter key. 5. The selected application should now close, and your system might恢复正常. If this doesn't solve the problem, there could be other underlying issues, such as hardware problems or a software malfunction. In such cases, it's recommended to seek further assistance or contact Apple support.

Step 1. Press and hold the "Command + Option + Esc" keys simultaneously on your iMac keyboard. This will promptly bring up the "Force Quit Applications" window.

Method 4: Free Up iMac's Disk Space

Emptying the Trash on an iMac is the most effective way to free up its disk space. Many users begin and conclude their hard drive cleanup process by deleting items in the Trash. On an iMac, even after you right-click and drag a file to the Trash, it still needs to be manually emptied to fully remove it.

Without software or settings that automatically empty your trash, its contents would accumulate over time and take up a considerable amount of space. Fortunately, reclaiming disk space is now a straightforward process requiring just a few clicks. Here's how to do it: 1. Locate the Trash icon on your Dock. It usually appears as a small wastebasket. 2. Click on the Trash icon to open it, revealing the files and folders that have been deleted but not yet permanently removed. 3. If you want to remove specific items, select them by clicking on them individually or using the Shift key for multiple selections. Alternatively, press "Command + A" to select all items. 4. Once you've made your selection, click on the "Empty Trash" button in the top-right corner of the window. Alternatively, you can right-click (or Control-click) within the Trash window and choose "Empty Trash" from the context menu. 5. A confirmation prompt may appear, asking you to confirm your action. Click "Empty Trash" again to proceed. If any files are in use by other applications, you might need to force quit those apps or restart your Mac to fully empty the Trash. 6. After confirming, the selected items will be permanently erased, freeing up the occupied space on your hard drive. Remember that once you empty the Trash, the files are gone, and there's no way to recover them unless you have a backup. So, always double-check before emptying the Trash to avoid losing important data.

Step 1. You need to right-click on the Trash icon on your iMac.

Step 2. Click on the "Empty Trash" option.

Step 1. Shut down your iMac by pressing and holding the power button for a few seconds.

Step 2. Restart your device, and quickly press the Command + R keys simultaneously. Release them once you see the Apple logo on the screen.

Final Thoughts

To delve deeper into why your iMac won't turn on or won't proceed past the Apple logo, let's explore how the iMac typically boots up. When your iMac is restarting or rebooting, it goes through a process of verifying various hardware connections. Following this, it checks the functionality of key components like the Central Processing Unit (CPU), Graphics Processing Unit (GPU), Random Access Memory (RAM), and the hard disk.

The iMac proceeds to install the startup hard drive and its system partition once these specifications are verified. During this process, you might observe the Apple logo and a loading bar on the iMac's screen as the startup hard drive is being identified.

The Mac boots up when the macOS successfully controls all software and hardware elements. The iMac will only progress past the Apple logo if the system can access the required macOS data or if the macOS is managing certain applications. Consequently, the iMac's unresponsiveness is due to file system corruption and software incompatibility.

If your iMac's files get deleted, it would be advisable to download a professional data recovery software like Data Recovery Wizard for Mac.
