Recently my sister asked me to reinstall the macOS High Sierra on her iMac because it stopped working correctly. I thought that it would be easy to do but I was mistaken. I successfully installed the macOS Mountain Lion (when using the NetBoot it automatically selects the version of macOS with which the iMac was shipped with). But then I was facing multiple issues trying to update macOS from Mountain Lion to High Sierra via the Mac App Store.
After downloading a copy of macOS High Sierra from the Mac App Store, I started installing the update. The Mac rebooted, and it seemed that everything was going well, but it was not. The progress bar did not move at all, or moved very slowly. I waited a few hours…
I began to figure out what was going on and found out the following. Attempting to download macOS High Sierra from the Mac App Store I found that a small 19 MB version of the 'Install macOS High Sierra.app' file downloads to the 'Applications' folder, rather than the complete 5.2 GB installer file. That's the problem.
The tiny 19 MB incomplete installer requires an internet connection during usage to download the rest of the High Sierra update files. Additionally, it does not allow me to create a macOS High Sierra USB installer drive for use on multiple computers.
Are macs good for music production. I've found a new workaround, and in this tutorial, I'll show you how to download the complete 'Install macOS High Sierra.app' file from Apple server using the 'macOS High Sierra Patcher' app instead of via the Mac App Store.
About the app
In this workaround, we're going to use the macOS High Sierra Patcher app from the dosdude1.com. This app is intended for those with unsupported Macs and Hackintosh users, but any Mac user can use the app to be able to download the complete macOS Mojave installer file from Apple server. For our purposes in this particular walkthrough, we will use the app only to download the complete installer file.
Note! This method relies on a third party app from an unverified third party source. If you are not comfortable with using unvetted and unverified software, do not follow this process.
Let's begin
Downloading the complete 'Install macOS High Sierra.app' file from Apple server using the 'macOS High Sierra Patcher' app is a really easy process. Now, step by step guide.
Go to the official website of the 'macOS High Sierra Patcher' app here and download the app.
Launch the 'macOS High Sierra Patcher' app.
Note! By default, macOS preventing apps from unidentified developers or sources from being launched. So you most likely will get an alert message that says: 'macOS High Sierra Patcher.app can't be opened because it is from an unidentified developer'. To allow just one specific app to run do the following:
- Hold down the
Controlkey and click the app icon. From the contextual menu chooseOpen. - A popup will appear asking you to confirm this action. Click the
Openbutton.
Ignore everything about patching, instead pull down the 'Tools' menu and choose 'Download macOS High Sierra…'.
Confirm that you want to download the 'Install macOS High Sierra.app' file, and then point it to a location to save on the hard drive.
Close the 'macOS High Sierra Patcher' app when the download is complete and locate the 'Install macOS High Sierra.app' file you downloaded.
Conclusion
That's it, you're done. Now you have the complete 'Install macOS High Sierra.app' file downloaded. So simple isn't it?
You can confirm that you have the complete 'Install macOS High Sierra.app' file by getting info on the file. For this simply select the file and click the Spacebar key (or right-click on the file and choose 'Get Info'). The complete installer should be around 5.2 GB rather than the tiny 19 MB incomplete installer that requires additional downloads.
Note! Remember, the 'Install macOS High Sierra.app' file deletes itself automatically after macOS High Sierra has successfully installed. Therefore, you may want to make a backup by having previously copied it to external storage.
Let me know in the comments section if you know another way to download the complete 'Install macOS High Sierra.app' file rather than the tiny incomplete installer.

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.
Mac os notepad. 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.
How To Install High Sierra On Old Imac
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

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
