In the Overview tab, look at the Mac model year below the OS version number. If the year is the same or above the previous compatibility list, then you should be able to install macOS Catalina formally. If not, read on. Make your old Mac support macOS Catalina. Older Mac owners don't have to worry. It's not the end of the world. The full operating system is a free download for anyone who has purchased Mac OS X Snow Leopard, Lion, or Mountain Lion or has a Mac preloaded with OS X Mavericks, Yosemite, El Capitan, or macOS Sierra. Download the Application from the Mac App Store using your Apple ID on any Mac or functional computer running OS X 10.7.5 or later.

MacOS Sierra :
Apple's latest desktop operating system is macOS Sierra, All MacBook and iMac models prior to Late 2009 and all MacBook Air, MacBook Pro, Mac mini, and Mac Pro models prior to 2010 are not officially supported by macOS Sierra, but there is a way to install the new software on older, unsupported devices.
Supporting devices
- Early-2008 (or newer) Mac Pro, iMac, or MacBook Pro
- Late-2009 (or newer) MacBook Air or unibody MacBook
- Early-2009 (or newer) Mac Mini or white MacBook
List of requirements:
- The installation file macOS Sierra Developer Preview.
- USB flash drive of at least 8GB.
- Tool macOS Sierra Patcher, available here.
How to install macOS on unsupported models :
Step 1: Connect the flash drive to the computer , open Disk utility and format the USB flash drive with format as Mac OS Extended.
Note : If you are formatting a whole disk or USB Also make sure you use GUID partition table.
Step 2: Run the utility 'macOS Sierra Patcher' and in the program window, specify the copy you previously downloaded the installation file 'macOS Sierra Developer Preview Installer'.
The program should confirm the successful validation of the image with the message 'Successfully verified as 'Install 10.12 Developer Preview'.

Step 4: After run your Mac from a flash drive with macOS Sierra. To do this, after you restart the computer hold the Alt keyboard button.
Step 5: After running the installer, open Disk utility.
Step 6: Select the disk or partition you put the new OS and delete all the data on it, making sure the format is OS X Extended (journaled). If you format the entire disk, choose GUID.
Step 7: Continue with the normal installation of macOS Sierra.
Step 8: After installation is complete, restart your computer and boot into the installation USB again. At this time you need to open the application Post Install macOS.
Step 9: In the software, select the model of your Mac. The tool will automatically propose the recommended settings depending on your computer. You can change them on your own.
Step 10: Select the Volume, select the drive on which you installed macOS Sierra and click Patch.
Step 11: once completed, press Reboot. Before rebooting may take several minutes required to rebuild the cache.

Features
- 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.
- Apple Pay is now part of macOS, not just iOS.
- Optimized Storage can store infrequently used files in iCloud while keeping them immediately available any time you are online.
With macOS Sierra, Apple has once again raised the bar on which Macs can install and run the newest version of the Mac OS. But as sometimes has happened in the past, there are workarounds that make it possible to install Sierra on some unsupported Macs.
A huge thank you to Collin Mistr for developing and sharing his macOS Sierra Patcher Tool for Unsupported Macs. Mistr is a member of our Low End Mac group on Facebook, and he's been sharing this tool ever since he figured out how to install the first public beta of Sierra. Several members of our group have used the tool and shared their results.
Apple Requirements for macOS Sierra
Your Mac must have at least 2 GB of memory and 8.8 GB of available storage space. You must also be running Mac OS X 10.7 Lion or later. (For those still on OS X 10.6 Snow Leopard, you can upgrade to OS X 10.11 El Capitan for free and then install macOS Sierra.)
- Late 2009 iMac or newer
- Late 2009 MacBook or newer
- Mid 2010 MacBook Pro or newer
- Mid 2010 Mac Pro or newer
- Mid 2010 Mac mini or newer
- Late 2010 MacBook Air or newer
All Macs introduced in the past six years are supported, as well as the consumer MacBooks and iMacs from late 2009, which are almost 7 years old. The official macOS Sierra installer will refuse to install on anything older.

Real Hardware Requirements for macOS Sierra
Again, your Mac needs at least 2 GB of RAM and 8 GB of available storage, and you'll need a USB drive (thumb drive or hard drive) at least 8 GB in size. You will also need a Mac with an Intel Penryn Core 2 Duo or later CPU, since Sierra requires SSE4.1 – and older versions of the Core 2 Duo, such as Merom, and older Xeon chips (used in the Mac Pro) don't have it.
mac OS Sierra Patcher Tool for Unsupported Macs supports the followining:
- Early 2008 Mac Pro or newer
- Early 2008 iMac or newer
- Early 2008 MacBook Pro or newer
- Late 2008 MacBook Air or newer
- Early 2009 MacBook White or newer
Where Apple only supports some Late 2009 and Mid 2010 Macs, Mistr's patch supports all Early 2009 Macs, some Late 2008 Macs, and even some Early 2008 Macs. We have a full list of Macs that can unofficially install Sierra using using the Unsupported Sierra tag. We will also be updating these profiles with #unsupportedsierra as time permits.
You Can Install It, But…
That's a lot more low-end support than Apple offers, so what's the catch?
There has been an issue with some of the Apple AirPort hardware in older Macs, but other than that, it's pretty much clear sailing. The AirPort support depends on which WiFi module your Mac uses. If it is not the Broadcaom BCM4321, you're set.
Other issues include the trackpad in the 2009 MacBooks and loss of volume control on the Early 2008 iMac. Details below.

Unsupported Devices
- The Broadcom BCM4321 WiFi module used in many older Macs is not supported. You will need to replace it with a compatible module or use a USB WiFi dongle. Models that may have this module include:
- Early 2008 Mac Pro (MacPro3,1)
- Early 2009 and Mid 2009 MacBook (MacBook5,2)
- Early 2008 and Late 2008 MacBook Pro (MacBookPro4,1) but the 15″ Late 2008 MacBook Prois supported
- Early 2008 iMac (iMac8,1)
- Early 2009 and Late 2009 Mac mini (Macmini3,1)
- Late 2008 and Mid 2009 MacBook Air (MacBookAir2,1).
- The trackpad in the Early 2009 and Mid 2009 MacBooks is not fully supported. Sierra sees it as a standard mouse; you cannot change the trackpad orientation settings.
- Some Early 2008 iMacs have an audio issue that will not let you adjust sound volume.
Real World macOS Sierra Requirements
Memory
Install Mac Os Sierra On Pc
Sure, you can install and run macOS Sierra on a 2 GB Mac, but you're not likely to be happy with system performance. You have a couple browsers running or several tabs in one browser, and that amount of memory will really hobble performance.
Heck, I find 3 GB on my 2.0 GHz 2007 Mac mini with OS X 10.6 Snow Leopard barely adequate. Then again, I often have 3-4 browsers running, many open tabs, and some additional apps.
My 2.0 GHz Late 2008 Aluminum MacBook has been running OS X 10.9 Mavericks and 10.11 El Capitan decently with 4 GB of memory, and that should be adequate for most users. Power users, however, will want at least 8 GB of memory.
A Fast Drive
Nothing will make your aging Mac seem fast like a Solid State Drive (SSD). Where hard drives are limited in how fast they can read data off a spinning platter, SSDs have no such limitation. Speed is almost completely limited by the speed of the SATA connection in your older Mac. Ipadian alternative for mac. Macs with 1.5 Mbps SATA will seem very fast with an SSD, those with 3.0 Mbps SATA will seem wicked fast, and those with 6.0 Mbps SATA will seem insanely fast.
SSDs have become very affordable over the past year. I have 256 GB and 480 GB SSDs in my Mac mini and MacBook respectively, and they made a world of difference.
If you need really high capacity or are on a very tight budget, look into newer 7200 rpm hard drives to replace your older hard drives. Newer drives tend to be faster and have larger data buffers, which boosts performance.
A third option if hybrid hard drives, which are part hard drive and part SSD. The drive itself manages which files are on the SSD and which remain on the hard drive platters, much like Apple's Fusion Drive. I have tried hybrid, and while it was nicer than a straight hard drive, it doesn't compare with a full fledged SSD. For some users in some applications, though, it might be a perfect mix of hard drive capacity and sometime SSD throughput.
In Closing
We Mac geeks have had a long history of hacking Mac OS X to run on unsupported hardware – starting with OS X 10.2. The biggest success was probably the unsupported installer hack for OS X 10.5 Leopard, allowing easy installation on Macs with G4 CPUs below the official 867 MHz threshold.

Collin Mistr's patch is the same kind of thing for macOS Sierra. If your Mac is not supported by Apple but is by Mistr's patch, give it a try. I think you'll like it.
