Say hello to macOS 10.13 High Sierra, the new operating system for Mac desktops and notebooks that brings some impressive under-the-hood refinements. If you were expecting some big overhauls, chances are you’ll be disappointed at a first view. But look closer and you’ll discover the fine details that amount to a better user experience and more power for your Mac.
Upgrading to macOS High Sierra is seamlessly simple, taking up little time and almost no effort. And with the upgrade guide we’ve prepared, you’re going to be running the new OS in no time.
Why you should upgrade to macOS High Sierra
The team at Apple went right on target, tweaking those features and apps that promise to be in the spotlight in the near future. With a new and improved AFPS file system, a faster browser (which promises to be the fastest on the market), stellar graphics, better gaming capabilities, and VR support, macOS 10.13 is definitely here to make a stand.
To really give your Mac a boost, upgrading to the new High Sierra is kind of mandatory. Think only about how much space you’ll save with the new operating system that compresses video up to 40% more. macOS High Sierra also comes with an improved Photos app, that now offers professional editing tools that will keep you hooked to find the perfect composition. Of course, the most important upgrade comes from Metal 2, which promises stellar GPU and CPU capabilities while opening the world toward VR and AR.
So, to conclude: upgrade to macOS High Sierra for more space, speed, and power. We should have started with that, right?
How to prepare for the macOS High Sierra upgrade
Now that you’ve decided that you cannot live without the new macOS 10.13 High Sierra, it’s time to thoroughly prepare for the upgrade. Do note that the beta version now available may not contain all the features, so if you want to upgrade for a specific feature, make sure it’s included. Let’s go!
In order to prepare to upgrade to High Sierra you should, of course, verify if your Mac is compatible with the new system. As a general rule, any late 2009 Mac or newer will theoretically be able to run it without any issues.
Next, you should do a thorough Mac cleanup to have it running smoothly even before upgrading. A complete cleaning process includes deleting duplicate documents, photos, and files, while also removing temporary files and cache data that built up in the background. You can do this manually (if you have the patience) or you can turn to an app such as CleanMyMac X to have it do all the dirty work for you.
Having a healthy Mac is key to making the most and enjoying the best of macOS High Sierra. Thus, it’s mandatory to check if your Mac has any issues before performing the upgrade. How?
Open Disk Utility
Select your startup drive
Click on the First Aid tab
If you’re lucky, your Mac won’t have any problems. But if you live in the real world, you’ll have to perform some repairs by using the Repair Disk. Restart and hold Command+R to perform the repairs with Disk Utility.
The final preparation step regards the free space necessary for macOS High Sierra. The official sources from apple.com recommend having 8GB of free space before upgrading to the new system, but we feel more comfortable with reserving about 15GB. What can we say, we like our space. If you don’t have enough space, that means you Mac still needs a bit of cleaning.

How to backup Mac before the upgrade
Backing up your Mac before a major upgrade is a necessity, especially if you’re going for a beta version. You don’t want to risk losing any precious info, so there’s no excuse for skipping this step.
You can easily backup your Mac by turning to Apple’s own software, Time Machine, that saves a copy of everything on your Mac on hourly, daily, monthly, and weekly backups. What’s more, except the automatic backups, you can also customize the process and have your most precious docs and files backed up manually from System Preferences.
In order to use Time Machine, you also need an external storage device. How big? The bigger the better. Choose your favorite from USB, SDD, NAS drive, or Thunderbolt hard drive.
Step by step upgrade to macOS High Sierra
Once you’ve prepared your Mac for the upgrade, it’s time to get the process started. Read on to find a comprehensive guide to a fast and safe upgrade.
Choose a safe and trusted network for the upgrade All major upgrades should be done from a trusted network, adding speed and safety to your download and installation. The best place to perform the upgrade is from the comfort of your home network and you should avoid WIFI connections and especially hotels, restaurants, or public networks.
Log into iCloud This step is pretty straightforward, yet necessary for the upgrade process, as many Mac apps have iCloud integrated parts. So, to have everything run smoothly, log into your account, and proceed.
Update to the latest version of your current OS To avoid any problems in the upgrade process, having the latest updated version for your current OS is mandatory. Why? Because your OS is going to be as stable as possible, with all the initial issues fixed and all bugs eliminated. Make sure you’re running the latest updated version by checking the Updates folder in the App store. It’s also important to have all 3rd party apps updated to their latest version as well. Check the apps purchased through the App Store by using the same method as above. For the other apps you’ve externally brought in you’ll need to perform a manual update.
Download macOS High Sierra Right now, macOS High Sierra is already available for all users. You can download it in the standard fashion on the Mac App Store. Here's the direct link.
Upgrade to macOS High Sierra Open the installer from Applications (if it doesn’t open automatically) and hit continue. The on-screen instructions are going to make it really easy for you, so follow them religiously and you won’t be able to do any wrong. That’s it!
Next, make sure to set up for automatic updates from your System Preferences and the App Store, in order to always have your Mac performing at its best.
So there you have it! We hope you enjoy the upgraded features and your Mac’s new regained speed and, hopefully, extra space.

Technical problems are frustrating, and troubleshooting issue is time-consuming. When your MacBook Pro keeps shutting down on Startup, you can't just ignore the problem. You're dead in the water. You need a solution immediately. So, instead of throwing the computer out the window, let's take a look at what could go wrong. Then, we'll go over tips for fixing your computer and making sure it never happens again.
Part 1. Why MacBook Pro Keeps Restarting
You're wondering: 'Why does my MacBook Pro keep restarting?' The answer is that when you install new software solutions on your MacBook Pro, it can lead to 'kernel panic' (or KP) which leads to unexpected restarts. A kernel panic is really not as scary as it sounds. When your computer's OS encounters an internal fatal error on bootup, and it can't safely recover or continue, it will display an error message informing you that it needs to reboot.
There can be many reasons why your MacBook keeps rebooting.
The most common issue is conflicting applications.
Another issue could be incompatible hardware or peripheral devices.
It could be an issue of not enough RAM or hard drive space.
The plugins or drivers could be out-of-date.
When your MacBook keeps restarting, this is what happens:
The system detected a problem and it gives an error message that it must restart to fix the issue.
If the system is truly stuck in the reboot cycle, the system will shut down.
In general, a message will pop up on your Mac screen showing you 'Your Computer restarted because of a problem.'
Part 2. How to Fix 'Mac Keeps Restarting'
So, by now, you have an idea of why your MacBook keeps restarting, but how do you fix it? Take a systematic approach to troubleshoot, starting with the hardware. As you test the potential suspects, you can cross it off your list and move on to the next possibility.
HARDWARE CONFLICT
The kernel panic can be caused by hardware conflicts. So, if you've recently installed new RAM, a hard drive, a printer, or other devices, the addition(s) may be contributing to the problem
Solution: Check the devices and hardware that you've hooked up to your MacBook Pro.
1. Turn off your MacBook Pro.
2. Disconnect all devices including printers (excluding the display, mouse, and keyboard).
3. Restart your MacBook.
4. Use your MacBook for the period of time that would typically have resulted in a restart.
>> If your MacBook restarts, check the status of your internal RAM and any other hardware.
>> If your MacBook does not restart, turn off your system and reconnect one device at a time per restart to troubleshoot your hardware issue.
SOFTWARE CONFLICT
Problems can pop up when you install new software on your MacBook Pro. There could be a compatibility issue, or it could be that the lack of space on your hard drive is contributing to the problem, and making it appear that your issue is software related.
Solution: Check the software that you've installed on your MacBook Pro.
1. Hold down the Shift-button and boot into Safe mode.
2. Backup your user files to an external hard drive.
3. Update the software on your MacBook Pro.
If the problem persists and is not resolved with the reinstall of your software, it may be a recurring issue with corrupt software. It's not uncommon to be required to reinstall your software, so it's important to make sure you're regularly backing up your system.
Solution: Discover corrupt software.
1. Update the corrupt software application.
2. Reboot your computer.
3. If you aren't able to reinstall or update the software application..
>> Uninstall or delete the application.
>> Use an app-installer tool to completely remove all trace of the corrupted app.
4. Reinstall the application.
If the 'Kernel Panic' error is associated with random software applications, the problem probably has nothing to do with the applications themselves, but more to do with drivers or other conflicts.
Solution: Fix disk permissions.
The problem of faulty disk permissions is yet another way that your software applications can go wrong and produce the 'Kernel' error. The process of fixing permission errors is one of the most frequent troubleshooting tasks that are recommended beyond just when your iMac keeps restarting. (The diagnosis is often incorrect, but it is a safe thing to try.)
For OSX Yosemite or older..
1. Press Command + R to restart your MacBook Pro.
2. Open Disk Utility.
3. Select 'First Aid,' then 'Repair Disk Permission.'
For macOS Sierra or OSX El Capitan ..
1. Open CleanMyMac X.
2. Select advanced Maintenance module.
3. Repair the disk permissions.
Fix the disk space issue..
We recommend maintaining a 20% margin for storage space, but that's just a safe estimate. Before you get started, consider which application and files you need to keep on your computer. Buy minecraft for macbook air. If they are old, if they are duplicated elsewhere, or if they are remnants of previous projects, delete (or back-up and remove) the files from your MacBook Pro.
If you don't have enough free space via virtual or physical memory, your system will lag. You'll see poor performance. You may also see the Kernel Panic issue.
To check to see if a lack of hard drive space is the issue, select the Apple menu.
>> Select 'About This Mac'
>> Select the 'Storage' tab.
To resolve the disk space issue, install a larger hard drive.
To resolve low capacity hard drive space issues, without installing a new hard drive, delete files or programs to free up space.
Run a CleanMyMac app to free up additional hard drive disk space.
Solution: Launch Disk Utility
You can fix corrupted files with your Disk Utility, which allows you to perform some tasks related to your storage and hard disks.
1. Select the Apple menu.
2. Select Restart
3. Hold down Command + R as your MacBook Pro is restarting.
4. Select Disk Utility.
5. Select First Aid.
Solution: Disable Startup Items
When you have too many startup items set to launch at startup, your MacBook Pro's processor can be overloaded and overloaded, which can lead to a Kernel Panic error and an auto restarts. Disable startup items to see if that's the reason for your error issues.
1. Select the Apple menu.
2. Select System Preferences.
3. Select Users & Groups.
4. Select your username from the menu.
5. Select the Login Items tab
6. Select a startup item to disable and then select '–'.
7. Restart your MacBook Pro.
Continue this process until all the startup items are disabled. You may be surprised by how many items are being loaded at startup. You can add back one startup at a time and reboot between each addition, so you can determine which item is causing a problem. You can use the CleanMyMac app for maintenance that may resolve your issues more quickly.
Solution: Reinstall a clean MacBook Pro operating system.
When other fixes do not resolve the reboot issue, you need to reinstall a clean install of the operating system on your MacBook Pro.
1. Restart your Macbook Pro.
2. Hold down Command + R as your MacBook Pro is restarting.
3. Select 'Reinstall macOS' or 'Reinstall OS X' to initiate a clean install of the OS that came with your MacBook Pro.
Solution: Recover Lost Files
Recoverit Data Recovery is the best file recovery software for your MacBook Pro.
You can quickly and easily recover files you've lost by reinstalling the MacOS.
Recoverit supports the recovery of photos, videos, documents, archives, and more than 1,000 other types of files.
You can also scan your hard drive and preview the files you want to save before you initiate the recovery process.
Recoverit allows you to recover the Desktop folder, as well as other content.
Step 1. Launch Recoverit
Install Recoverit, and open the application. If you've already installed the application, select the 'Recoverit' icon from the MacBook Pro desktop. It can take a few seconds to launch the program.
Select the source location, where you've lost your files.
Initiate the scan to search for the lost files.
Recoverit displays a list of all the files that you can recover. Review the files to determine which ones you need to recover. Select the 'Recover' button.
2. Recover Files
To recover files, repeat the main three steps.
Select the source location.
Initiate the scan to search for the lost files.
Preview and recover.
You should be able to get a listing fairly quickly. If you don't see the file(s) you need to recover, you can still try one more method of recovery.
Select 'All-around Recovery' to run a more in-depth scan and see if you can recover your files. The results are usually better with the deeper scan.
Part 3. How to Prevent 'Mac Keeps Rebooting' Issues
It's always preferred to resolve the reboot issue before you have the complaint: 'My Mac keeps restarting.'
