Mac Os Sierra Patcher Tool For Unsupported Macs

Автор:

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.

Nov 14, 2016  In this video, I go over the steps needed to install macOS Sierra on an unsupported Mac. The whole process is based around the macOS Sierra Patch Tool for Unsupported Macs, which is a program I wrote to allow all users to easily perform the necessary modifications. MacOS Sierra Patcher is a free-to-use application for Mac OS that allows you to easily create a modified install drive to use for installing macOS Sierra on unsupported Mac computers. Make sure SIP is disabled on the system you intend to install Sierra on.

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.

To extract the specific tables that I want. However, in Mac Excel 2011 VBA, querytables are not supported (properly). So these code do not work. Can someone kindly tell me how can I extract specific table from a webpage (for example, say web table 4 ) using 2011 Excel VBA Mac? Thanks a lot. Web query excel mac 2018. How to Get External Data from Web in Excel 2016 for mac V15.22 Hi, I have MS Excel 2016 V 15.22 in my MAC PC. But when I got to Data, External Data, I dont see the option 'From Web'.

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

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. 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.
