Waxa jira dhawr shay oo kala saaraya Laptop -ka Windows -ka iyo ^(Windows)MacBookga^(MacBook) ; Mid ka mid ah kuwan waa Software Update . Cusbooneysiin kasta oo nidaamka qalliinku wuxuu keenaa balastar amni oo muhiim ah iyo sidoo kale astaamo horumarsan. Tani waxay ka caawinaysaa isticmaalaha inuu cusboonaysiiyo khibradiisa aaladaha ay adeegsadaan. Habka cusboonaysiinta macOS waa mid fudud oo toos ah. Dhanka kale, cusboonaysiinta nidaamka qalliinka ee Windows waa waqti badan. In kasta oo soo dejinta macOS-ka cusub ay u muuqato mid fudud, waxay keeni kartaa arrimo inta lagu guda jiro rakibaadda isticmaaleyaasha qaarkood, sida qalad ayaa dhacay rakibidda macOS. Iyada oo la kaashanayo tilmaan-bixiyahan, waxaan hubin karnaa in xal-u-hubin ah si loo hagaajiyo rakibidda macOS khaladaadka.

Sida loo hagaajiyo Rakibaadda MacOS ayaa ku guuldareystay^{(How to Fix macOS Installation failed Error)}

Sababaha ka dambeeya rakibidda macOS ee ku guuldareystay waxay noqon kartaa:

• Adeegayaasha Mashquulka^{(Busy Servers)} ah: Mid ka mid ah sababaha ugu badan ee khaladku dhacay rakibidda macOS waa adeegayaasha Apple oo culayskoodu saaran yahay . Natiijo ahaan, soo dejintaadu waxay noqon kartaa mid guul dareysata, ama waxay qaadan kartaa maalin dhan in la shaqeeyo.
• Booska Kaydinta Hoose^{(Low Storage Space)} : Haddii aad isticmaalaysay MacBookgaaga wakhti aad u badan, markaa fursadaha waa inaad isticmaashay qayb weyn oo kaydin ah. Kaydinta aan ku filnayn ma oggolaan doonto soo dejinta habboon ee macOS cusub.
• Arrimaha Isku-xidhka Internetka^{(Internet Connectivity Issues)} : Haddii ay dhibaato ka jirto Wi-Fi-gaaga, waxaa laga yaabaa in cusboonaysiinta software-ka macOS uu hakad galo ama rakibidda macOS waxaa dhici karta cilad.

Qodobbada Lagu Xasuusto^{(Points to Remember)}

• Haddii Mac-gaagu uu ka weyn yahay shan sano^{(over five years old)} , waxa fiicnaan lahayd inaadan isku dayin cusbooneysiin oo aad ku dhejiso nidaamka hawlgalka Mac ee aad hadda ku socoto qalabkaaga. Cusbooneysiin cusub ayaa suurtagal noqon karta, oo si aan loo baahneyn u culeysin karta nidaamkaaga oo u horseedi karta khaladaad masiibo ah.
• Waxaa intaa dheer, had iyo jeer ku celi xogtaada^{(back up your data)} ka hor inta aadan dooran casriyeynta nidaamka. Maadaama caqabad kasta oo ku jirta habka rakibidda ay si qasab ah u horseedi karto qalad Kernel^{(Kernel error)} ie dib u soo kabashada MacOS si isdaba joog ah maadaama Mac uu ku xayiran yahay labada nooc ee nidaamyada hawlgalka.

How to Fix macOS Installation Failed Error

There are several thіngs that set a Windows laptop and a MacBook apart; one of these being Software Update. Every operating system update brings in important security patches as well as advanced features. This helps the user to upgrade their experience with the devices they use. The macOS update process is easy and straightforward. On the other hand, the operating system update on Windows is quite time-consuming. Even though downloading the new macOS seems simple, it may pose issues during installation for some users, such as an error occurred installing macOS. With the help of this guide, we can ensure a sure-shot solution to fix macOS installation failed error.

How to Fix macOS Installation failed Error

The reasons behind the failed installation of macOS can be:

• Busy Servers: One of the most common reasons for an error occurred installing macOS is overburdened Apple servers. As a result, your download may be unsuccessful, or it may take an entire day to process.
• Low Storage Space: If you have been using your MacBook for a significant amount of time, then the chances are that you have utilized a significant chunk of storage. Insufficient storage won’t allow proper download of the new macOS.
• Internet Connectivity Issues: If there is a problem with your Wi-Fi, the macOS software update may get interrupted or macOS installation failed error may occur.

Points to Remember

• If your Mac is over five years old, it would be best to not attempt an update and stick to the Mac operating system you are currently running on your device. A new update could potentially, and needlessly overburden your system and lead to catastrophic errors.
• Moreover, always back up your data before opting for a system update. Since any hindrance in the installation process may forcibly lead to a Kernel error i.e. reboot of MacOS repeatedly as Mac gets stuck between two versions of operating systems.

Method 1: Check the Log screen

If you are noticing that the installer on your screen is stuck in the download process, chances are that the download is not stuck in reality, it just seems to be so. In this scenario, if you click on the cross icon, the files may download imperfectly. To check if the download is processing properly, follow the given steps:

1. While observing the progress bar, press Command + L keys from the keyboard. This will show you more information about the download in progress.

2. In case, the download is stuck, you would be able to see that no additional files are being downloaded.

Method 2: Ensure Internet Connectivity

Many users have faced this issue because either their Wi-Fi connection was not proper or there was a DNS error. Make sure that your Mac is online before initiating the update.

1. Check if your internet is working properly by opening any website on Safari. If there are issues, restart your router.

2. Refresh Wi-fi on your system by toggling it off and then, on from the Apple Menu.

3. Check router DNS: If there are custom DNS names set up for your Mac, then they have to be checked as well. 

4. Perform an online speed test to check the strength of your connection. Refer given pic for clarity.

Method 3: Clear Storage Space 

As mentioned above, another common issue is low storage space on a disk. Our general usage utilizes a lot of space on the disk. Therefore, when there is lesser space on your computer, the installer may not download properly, or it may trigger an error occurred installing macOS problem.

Note: You need 12 to 35 GB on your computer to install the latest macOS Big Sur.

A quick way to clear up some space is by deleting the unwanted pictures/apps, as instructed below:

1. Open Settings on your device.

2. Click on Storage in General Settings, as shown below.

3. Select the app that you want to delete and click Delete App.

Method 4: Un-enrol from macOS Beta Version

The download of new updates could get blocked if your Mac is currently operating on the Beta version of macOS. Un-enrolling from Beta updates could help fix macOS installation failed error. Here’s how to do so:

1. Click on Apple icon > System Preferences.

2. Here, click on Software Update.

3. Now, click on the Details option located under This Mac is enrolled in the Apple Beta Software Program.

Method 5: Download Installer via App Store/Apple Website

Method 5A: Through App Store

In several cases, people have reported that their macOS installation failed when they downloaded the update from System Preferences. Moreover, users who still use macOS Catalina complained of an error stating: the requested version of macOS couldn’t be found displayed on the screen when they tried to update their macOS through Software Update. Therefore, you can try downloading the software from the App Store to fix macOS installation failed error.

1. Launch the App Store on your Mac.

2. Here, search for the relevant update; For example: macOS Big Sur.

3. Check the Compatibility of the chosen update with your device model.

4. Click on Get, and follow the on-screen instructions.

Method 5B: Through Apple Website

In order to stop receiving this error, one can also try downloading the Mac installer directly from the Apple website. The differences between the two installers are:

• The installer downloaded from the website, downloads a lot of additional files as well as the data required for all Mac models. This ensures that the files which have gotten corrupt are renewed, and the installation takes place seamlessly.
• On the other hand, the installer that gets downloaded through the App Store or through System Preferences downloads only those files that are relevant to your Mac. Hence, the corrupt or outdated files do not get a chance to repair themselves. 

Method 6: Download macOS via MDS

This is an alternative to download macOS update files. MDS or Mac Deploy Stick is an in-built Mac tool. This app can reinstall or uninstall a macOS automatically.

Note: MDS should be downloaded & installed during the macOS installation process.

1. The MDS App is available through web pages of various developers, the preferred one being MDS by TwoCanoes.

2. Click on Free Download and run the installer.

3. Launch the MDS App and select the macOS version you wish to download and install on your Mac.

You should be able to download the said update without facing macOS installation failed error. If not, try the next fix.

• All Content is selected.

5. Restart the Mac and then try the installation.

Method 8: Boot in Safe Mode 

This method is about continuing your installation in the Safe Mode. Fortunately, all the background download and launch agents are blocked in this mode, which tends to promote successful macOS installation. To boot your Mac in the Safe Mode, follow the given steps: 

1. If your computer is switched on, tap on the Apple icon from the top left corner of the screen.

2. Select Restart, as shown.

3. While it restarts, press and hold the Shift key. 

4. Once you see the login screen, you can release the Shift key.

This should fix macOS installation failed error.

Method 9: Reset PRAM Settings

Resetting the PRAM settings is a great alternative to troubleshoot any issues pertaining to the operating system. The PRAM and NVRAM store important settings such as the resolution of your display, brightness, etc. Therefore, resetting the PRAM and NVRAM settings may also help fix avoid an error occurred installing macOS. Here’s how to do so:

1. Turn off the MacBook. 

2. Now, Switch it On by pressing the Power button.

3. Press Command + Option + P + R keys on the keyboard.
