Do you have a problem with your Mac not booting up? This is a problem with many older Mac models. The reason behind why a Mac won’t boot or start up is often hard to figure out because there is no information coming up on display, why a Mac won’t boot.
However, there are some tips you can try to make sure your Mac still starts up. You can read these 8 tips in this article.
These are tips that everyone can apply regardless of computer knowledge.
Mac does not startup
Connecting your Mac to a power supply
Is your Mac connected to the power supply? Sometimes a Mac needs more power than it has available to boot up. Therefore, connecting the Mac computer to power may cause the Mac to boot up.
Although it seems obvious, it is something that many people overlook. A steady power supply is sometimes all that is needed to get your Mac to start up. If the Mac still won’t boot up, let the battery charge for a few minutes and then try to restart it.
Swap Power Cables
If your Mac runs out of power, the problem may not be with the battery but with the power cable. Try a spare cable if you have one lying around. If your cable uses the optional length extender, remove that part and plug in the Mac.
The goal is to reduce the number of possible short circuits or breaks in the power cord.
You should also remove any peripherals such as printers or USB connectors when you boot the Mac. Sometimes peripherals can cause an error that causes macOS to fail to boot or the Mac to not boot at all.
If your Mac has power but won’t boot (or won’t go beyond the Apple logo), try power cycling. To do this, disconnect the power cable and hold down the power button for at least ten seconds. If your Mac is an iMac, unplug it for at least ten seconds.
This process clears any remaining memory in the RAM and allows you to perform a boot. After ten seconds, restart the Mac computer by pressing the power button. A power cycle is one of the most straightforward troubleshooting steps.
You can also try safe mode in macOS by pressing the power button and holding down the SHIFT key until the Apple logo appears and the login screen is displayed. Then, log in to your Mac, and you should see the text Safe Boot in the upper right corner.
Turn on the built-in diagnostics program if your Mac still won’t boot after these initial steps. Next, press the power button and then hold down the D key. Hold down these keys until a screen asks you to select your language.
The diagnostics program will then run a check on your Mac. You will also see the diagnostic program’s serial number and version installed.
After the minutes have passed, you will see a solution or a reference code. You can use this referral code to find more information about the problem or report the issue to Apple Support workers.
All Macs have a built-in recovery partition that provides access to utilities to fix a wide variety of problems. In addition, this partition can boot independently of the rest of the machine.
Even if malware or something else has caused most of the hard drive to be unusable, recovery mode can help.
Press the power button, hold down Command + R. Wait until the Apple logo appears on the screen, and release the keys. The machine will continue to boot until a “Recovery” menu appears.
This menu allows you to restore from a Time Machine backup, reinstall macOS, seek online help, or use the Disk Utility.
The first step should be to use the Disk Utility to scan your hard drive. Next, right-click on the disk and choose Run First Aid. This will automatically check for possible problems and fix anything it finds.
If this doesn’t work, you can also try Internet Recovery Mode. You can access it by holding down the Option + Command + R keys immediately after pressing the power button.
If all else fails, you can use this menu to restore your Mac to a previous version from a Time Machine backup.
Reset the SMC
The SMC, or System Management Controller, controls many of the functions of your Mac, including its ability to wake up when you open it. Resetting the SMC is a tool that can fix several different problems. There are several ways to do this, depending on the Mac you have.
If you have a desktop Mac such as an iMac, unplug it and wait 15 seconds. Then, plug it back in, wait another five seconds, and reboot your Mac. This simple process will reset the SMC.
If you have a Macbook Pro, you will need to press several keys at once. First, hold down the right Shift key, then the left Option (Alt) key, and then the left Control key for about seven seconds. Then, while holding down these keys, hold down the power button for the same amount of time.
After you have done this, release the keys and restart the computer.
For other Macbooks, hold down the left Shift, Control, and Option keys and the power button for about ten seconds. After you release the keys, restart your Mac.
If nothing helps, you can reinstall macOS using the recovery options described earlier. The second option in the recovery options is to reinstall macOS. This, of course, only works if you already get to the recovery options.
However, if your data is corrupt, you may lose access to it anyway. The best option is to perform routine backups via Time Machine to ensure that your data is protected no matter what.
If it no longer works, contact Apple Support and ask Apple Support for an expert to help you further with the problem.
