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.

When Apple released Mac OS Sierra, it broke the WiFi card in your 2006-2012 Mac Pro. Even if you had WiFi before, after installing Sierra, you may have noticed 'No WiFi Hardware Installed' where your WiFi menu used to be. This card restores your native driverless plug-and-play WiFi. You may also use this kit to add WiFi capability to any Mac. MacBook (late 2009 and later) iMac (late 2009 and later) MacBook Air (2010 and later) MacBook Pro (2010 and later) Mac Mini (2010 and later) Mac Pro (2010 and later) Here's the patch tool by dosdude for High Sierra, Iused his former patch to do the Sierra upgrade. It also tells you how to install it. It is reported to work on theses unsupported. The Mac Pro 'Eight Core' 2.8 (Early 2008) is powered by two 2.8 GHz Quad Core 45-nm Intel Xeon E5462 (Harpertown/Penryn) processors with 12 MB of level 2 cache per processor (each pair of cores shares 6 MB), a 128-bit SSE4 SIMD vector engine, and 1.6 GHz '64-bit dual independent frontside buses.' If you recently upgraded to Mac OS X High Sierra (10.13.1), you may not be able to connect to the Internet (over Wi-Fi or Ethernet) including unable to browse web pages or open the App Store.Additionally, your Mac will display “green” in System Preferences and show a connected Wi-Fi signal indicating you have a network connection, however you cannot reach the Internet.

The same applies in this case, too, since the macOS High Sierra Patcher will render your iMac 8.1 Broadcom Wi-Fi chip useless for certain models. Macs that use the Broadcom BCM4321 Wi-Fi module will not have functional Wi-Fi when running High Sierra.

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

New Features

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.

Optimized Storage can store infrequently used files in iCloud while keeping them immediately available any time you are online.

In the files section of the application, you can choose one of the previously scanned documents.Read also:You can edit or view previous documents. The display option allows you to view all documents and images, then you can send them through many applications (Mail, Messages, add to notes, etc.). It seems strange that you can’t just click on the document to view it, you have to click on it and then click on the display option. It is also possible to copy and print documents from this screen.

Availability

Apple developers can download an early pre-release version of macOS Sierra today, and a beta version will be available to users in July. The full release is scheduled for Fall 2016.
