Upgrade Imac To High Sierra
MacOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion, Lion Your web browser downloads the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the.pkg installer inside the disk image. It installs an app named Install  Version Name. Upgrade OS to High Sierra? I have upgraded to El Capitan, but would like to know if the model could be upgraded (clean install) to High Sierra or perhaps Sierra? According to the spec's listed for the OS X High Sierra, this model should be able to be upgraded to High Sierra. High Sierra requires a newer Mac by default, but it also requires SSE 4.2, which is not present in 2007 iMacs by default. However, with the right CPU upgrades, High Sierra can be installed. The chipset doesn't see the numbers just right, the 700 MHz is merely a misnomer, nothing.
With macOS High Sierra, Mac users gain powerful new core storage, video and graphics technologies. A new file system ensures more efficient and reliable storage, and support for High-Efficiency Video Coding (HEVC) brings stunning 4K video at lower file sizes. Metal 2 powers virtual reality content creation, faster performance and more. The Core ML developer framework makes it easy to create apps with powerful machine learning that predict, learn and become more intelligent. macOS High Sierra also includes a number of refinements to the apps Mac users enjoy everyday, including Photos and Safari.
You can download and install macOS High Sierra OS for free in 2009 or later. Basically, if your Mac is currently running macOS Sierra system (macOS 10.12), you can smoothly upgrade to macOS High Sierra. The following is the device compatibility information released by Apple: iMac (Late 2009 or newer). Now, a 2009-era iMac isn't going to be able to take advantage of everything High Sierra has to offer. In fact, a late-2009 iMac is literally the oldest possible iMac that can be upgraded. We bumped up the internal RAM to the highest available spec (16 GB). But frankly, my iMac hasn't been able to add features for a while now.
'macOS High Sierra is an important update that makes the Mac more capable and responsive, while laying the foundation for future innovations,' said Craig Federighi, Apple's senior vice president of Software Engineering. 'High Sierra introduces new technologies for VR, high-efficiency video streaming, advances in storage technology and more, while apps such as Photos, Safari, Mail and Notes are refined to give users even more reasons to love their Mac.'

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 upgradeNow 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 upgradeBacking 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.
