- Answer (1 of 2): Don’t go with some third party website to download the DMG files. Also you don’t need any kind of DVDs as the upgrades are fully free. If you’re talking about Sierra, I will assume here that your Mac is fully compatible for Sierra.
- It is not officially possible to install macOS Sierra or use Xcode 9 (or later) on your iMac. So, for anyone else looking at this, the answer is yes, it is possible to run macOS Sierra on a 2007 iMac. After reading the iFixit post linked in the question, I was able to do a hardware upgrade.

Performing an El Capitan-to-Sierra upgrade is easy. Although it does not come like a push-one-button-and-proceed method, the truth is it’s quite close.
Requirements for Upgrading from El Capitan to Sierra
(which is what macOS Sierra wants to see in order to even boot) Our 7,1 iMacs support 800 FSB, I tried an E8135 from a 2008 iMac but the FSB on it is 1066 and the 7,1 didn't like that lol. I tried a few things but what it comes down to is the 7,1 only wants to see 800. Answer (1 of 2): with macs, you are generally safe with updating to the latest OS yes, some features might not work or run sluggishly like SIRI but if you spend s lit of time online, browsers or pages might not work unless you are running a version closer to 2017.
Before we proceed with our step-by-step guide, allow us to answer an important question that some Mac users have in mind: “Can an old Mac still upgrade to Sierra?”
The answer is, of course, a YES. However, there are a few minimum requirements that need to be met, such as the following:
- 2 GB RAM
- 8 GB Storage Space
- Mac Models: Late 2009 iMac, 2009 MacBook, 2010 MacBook Pro, 2010 MacBook Air, 2010 Mac Mini, 2010 Mac Pro
Once you are certain that your Mac has met the requirements above, make sure you have backed up your Mac. This backup will come in handy in case something comes up in the process of upgrading to High Sierra.
Pro Tip: Scan your Mac for performance issues, junk files, harmful apps, and security threats
that can cause system issues or slow performance.
Upgrading from El Capitan to Sierra
After backing up your Mac’s important files and folders, it’s time to get started. Here’s how to upgrade from El Capitan to Sierra.
1. Download High Sierra from the App Store.
High Sierra is available for download from the App Store. To get it, follow these steps:
- Open the Mac App Store by simply clicking on the App Store icon in the dock.
- Navigate to the Featured tab.
- Find macOS Sierra in the rightmost column and click on it.
- Click Download.
- At this point, the download will start. It may take long, especially if it’s your first time accessing the App Store. Just be patient.
- Once the download is completed, the installer should launch automatically.
2. Start the Upgrade.
With the High Sierra installer ready, it’s time to actually install it. Here’s how:
- The High Sierra installer should now be open on your Mac. If you have accidentally quit it, you can restart it by going to the Applications folder and double-clicking on the installer.
- Click Continue to proceed.
- Press on the Agree button to agree with the software licensing terms and agreements flashed on your screen.
- Click on the Agree button again to verify your action.
- Hit Install.
- A new dialog box will pop up, requiring you to input your administrator password. Provide that information and click Add Helper.
- The High Sierra installer will begin copying the system files to the new target drive. The progress will show in a new window.
- As soon as all the system files are copied, your Mac will automatically reboot. Don’t panic if the restart process takes a while. It only means your Mac is coping with the installation process.
3. Utilize the Setup Assistant to Complete the Installation.
Your Mac should already be finished with the basic installation process. The next thing you should do is run the Setup Assistant to configure some important macOS High Sierra options and settings.
Take note, though, that if your Mac is configured to ask for your login details, a normal login window will show. Provide your login credentials so you can proceed with the following steps:
- The Setup Assistant starts off by asking you for your Apple ID details. If you wish to leave everything as it is, click the Set Up Later option.
- Let the Setup Assistant configure all vital services that need your Apple ID credentials. Simply provide your Apple ID password and hit Continue.
- Click Agree if you agree with the Terms and Conditions flashed on your screen.
- You will be asked to verify your action again. To continue, click Agree again.
- The Setup Assistant should then continue with configuring your iCloud account information. It will also ask you whether you want to set up iCloud Keychain. You can just skip it to avoid confusing yourself.
- Next, there will be options displayed on your screen regarding how you wish to use iCloud for storing images and documents. Choose which of them apply to you by clicking on the boxes next to each one of them:
- Store Files from Documents and Desktop in iCloud Drive – This option will allow you to automatically upload files from your Desktop and Documents folder to your iCloud Drive. Be mindful, though, that Apple only offers a limited amount of storage space for free users. If all this free space is exhausted, you will be asked to purchase additional storage.
- Store Photos and Videos in iCloud Photo Library – This will let you upload videos and images from your Photo Library to iCloud. As with the first option, you have to remember that you only have limited free storage space.
- Hit Continue.
- Wait for the Setup Assistant to finish the setup process.
- You will know when it’s done because you will be taken to your desktop.
We hope you found this guide useful. But before you download macOS Sierra and perform an upgrade, do not forget to clean up your Mac with a reliable Mac repair tool first. This way, you can ensure that nothing comes your way and keeps you from making the most of High Sierra.

For the first time since Apple released OS X 10.8 Mountain Lion in July 2012, Apple has dropped support for a number of older Macs that had supported OS X 10.8 through 10.11 El Capitan. No MacBook and iMac models prior to Late 2009 and no MacBook Air, MacBook Pro, Mac mini, and Mac Pro models prior. OS X El Capitan (10.11) on Unsupported Macs macOS Extractor and MacPostFactor are apps that guide you through patching and installing OS X El Capitan (10.11), Yosemite (10.10), Mavericks (10.9), or Mountain Lion (10.8) on your older Mac. Whilst it does lessen security somewhat, it is not the end of the world, and OS versions prior to El Capitan do not include it anyway. Related tutorial: How to disable System Integrity Protection 7) Once everything is ready, launch the macOS Sierra Patcher application. Question: I read somewhere that it is possible to install the latest version of OSX 10.10 Yosemite on my Mac, even though the official installer refuses to install. Can you give me any directions? Answer: Installing newer versions of OSX on slightly older Macs that do not meet the official system requirements. I am currently researching installing OS X 10.13 High Sierra on unsupported Macs. I did the Sierra upgrade on a couple of MacPros 4,1 and it has worked excellently, after I did a firmware update patch to get it to read as a MacPro 5,1, so I am very optimistic on doing it again.
For the first time since Apple released OS X 10.8 Mountain Lion in July 2012, Apple has dropped support for a number of older Macs that had supported OS X 10.8 through 10.11 El Capitan. No MacBook and iMac models prior to Late 2009 and no MacBook Air, MacBook Pro, Mac mini, and Mac Pro models prior to 2010 are officially supported by macOS Sierra, although workarounds have been developed for most unsupported 2008 and 2009 Macs.
Mac OS X is no longer being called OS X, and Apple is not promoting Sierra with a version number either (however, it is internally identified as OS X 10.12). Now it’s simply macOS Sierra – in keeping with iOS, tvOS, and watchOS.
macOS Sierra was released on Sept. 20, 2016 and officially requires a supported Mac with at least 2 GB of system memory and 8.8 GB of available storage space. (We recommend at least 4 GB of RAM.)
Officially Supported Macs
All Late 2009 and later MacBook and iMac models are supported in macOS Sierra, as are all 2010 and newer MacBook Air, MacBook Pro, Mac mini, and Mac Pro computers.
Hacking macOS Sierra for Unsupported Macs
Hardware requirements for macOS Sierre include a CPU with SSE4.1, so it cannot be run on any Mac with a CPU prior to the Penryn Core 2 Duo. In theory, it should be possible to get Sierra running on any Penryn or later Mac. It may be possible to swap out the Merom CPU in some Macs for a Penryn, which would then allow Sierra to run.
Sierra can run with 4 GB of system memory, but as with all recent versions of OS X, more memory will allow it to run even better.
Colin Mistr has published a macOS Sierra Patch Tool, which currently allows you to install and run macOS Sierra on the following officially unsupported hardware:
- Early 2008 iMac or later
- Mid 2009 MacBook (white) or later
- Late 2008 MacBook Air or later
- Early 2008 MacBook Pro or later
- Late 2009 Mac mini or later
- Early 2008 Mac Pro or later
Note: If you have the Early 2009 Mac Pro and have installed the firmware update patch so it identifies itself as MacPro5,1, you can run the standard installer. You do not need the patch tool.
You will need a USB drive 8 GB or larger and Mistr’s patch tool, which is linked on his page. WiFi does not function on these unsupported systems if they have the Broadcom BCM4321 WiFi module:
- Late 2008 and Mid 2009 MacBook Air
- Early 2008 and Mid 2008 MacBook Pro
Siri comes to the Mac with macOS Sierra.
macOS Sierra can automatically sync all files on your Desktop and in your Documents folder with other Macs running Sierra. You can also access these files in your iPhone or iPad using iCloud Drive.
The new Universal Clipboard lets you copy on one device and paste on another – whether it’s a Mac with Sierra or an iPhone or iPad with iOS 10.
Tabs are almost everywhere in Sierra, and they work much as they do in your browser. Third party apps will also be able to use tabs.
Apple Pay is now part of macOS, not just iOS.
If you have an Apple Watch, Auto Unlock will authenticate you and log you in automatically when you approach your Mac.

Apple's OS X El Capitan in October got off to the fastest-ever one-month start for a Mac operating system.
Upgrade Imac 2007 To High Sierra
El Capitan, also tagged by Apple as OS X 10.11, was released on the last day of September: 31 days later it had been installed on another 25% of all Macs, bumping its total to 27%, according to U.S. analytics firm Net Applications.
The October increase was the largest one-month user share gain by an edition of OS X in the six years that Computerworld has recorded Net Applications' data, beating Mavericks and Yosemite, the two previous upgrades Apple handed out free of charge.
Net Applications estimates operating system shares by tallying unique visitors to its clients' websites. In the absence of definitive data from Apple, user share is one of the few proxies for real-world OS X adoption.
When the release dates of each edition were taken into account, however, El Capitan's average daily adoption rate only edged Yosemite's and turned out to be lower than Mavericks'. Those forerunners launched in the second half of October in 2014 and 2013, respectively, and so spread their biggest gains over a longer stretch than El Capitan: 41 days for Mavericks and 47 days for Yosemite.
Not surprisingly, the majority of those who migrated to El Capitan came from its immediate predecessor, Yosemite. Last month, Yosemite shed more than a third of its user share as its users upgraded.

But other, even older versions of OS X also lost user share last month. Each of those tracked by Computerworld -- from 2007's Leopard on -- fell at rates larger than their average decline over the previous 12 months. Mavericks, for instance, fell to 14% of all editions of OS X, a two-point slide that was double its earlier average.
Mac Os El Capitan Patcher Tool For Unsupported Macs
Approximately 90% of all Macs were eligible to upgrade to El Capitan when the operating system launched on Sept. 30. El Capitan will run on the same Macs that have run Yosemite, Mavericks, 2012's Mountain Lion and 2011's Lion.
On the flip side, a sizable number of Macs continued to run outdated editions of OS X last month. By Net Applications' data, about 16%, representing one in six Macs, was powered by a version that Apple no longer supports with security updates. Apple distributed the final security update for the three-year-old Mountain Lion in August. It continues to patch Mavericks and Yosemite, however.

The one-in-six who run unsupported operating systems seems to be the natural order. Not only has that same percentage of OS X users been on the retired list in earlier years -- even as new editions rolled out annually -- but in the Windows world, a double-digit fraction still run Windows XP, which left support more than a year and a half ago.

The free El Capitan upgrade can be obtained from Apple's Mac App Store, and supports iMacs as old as mid-2007, MacBook Pro notebooks from late 2007 on, and MacBook Air laptops from late 2008 going forward.
