Hello Apple's users!

 

Apple showed the list for all devices that will support this new OS.

 

  • MacBook (late 2009 and later).
  • iMac (late 2009 and later).
  • MacBook Air (late 2010 and later).
  • MacBook Pro (late 2010 and later).
  • Mac Mini (late 2010 and later).
  • Mac Pro (late 2010 and later).

If you want test this new OS, just join at Apple Beta Software Program, download and install it in a separate partition.  

 

Never use an Beta OS as your current OS, probably you'll have a lot of bugs.  ;)

 

But if you want upgrade your OS X 10.11 through App Store, use Time Machine for back up your Mac.

Actually, what is on the "compatibility list" is just an arbitary limitation set by the Sierra installer's OSInstall.mpkg file.

The operating system itself is quite happy to allow you to boot with some of the older SMBIOS e.g. MBP5,1 as long as the installation phase on the hard drive has been completed and your processor supports SSE4.

 

I managed to install Sierra on my legacy BIOS, Penryn based Core2Duo laptop (see signature) using a MacBook6,1 or MBP7,1 SMBIOS to bypass the installer limitation.  

 

At the first reboot after Sierra was installed on its hard drive partition, I switched to my usual MBP 5,1 definition that has worked well for the system since Snow Leopard...et voila!

 The operating system itself is quite happy to allow you to boot with some of the older SMBIOS e.g. MBP5,1 as long as the installation phase on the hard drive has been completed.

 

I managed to install Sierra on my legacy BIOS, Penryn based Core2Duo laptop (see signature) using a MacBook6,1 SMBIOS (late 2009) to bypass the installer limitation.  

 

At the first reboot after Sierra was installed on its hard drive partition, I switched to my usual MBP 5,1 definition that has worked well for the system since Snow Leopard...et voila!

Your comments about the limitations provided for the Hardware Compatibility List  could be extended to all the systems on which it is currently possible to install OS X 10.11.x El Capitan?

(In my case, for example, OS X 10.11.x El Capitan is installed on an Asus P5G41T-M LX motherboard with Intel Pentium Dual Core E2140 processor - NO SSE4.x - a configuration a little outdated, I know )

In some threads I have read that would be excluded from the possibility of installing Mac OS Sierra the CPU-based systems without SSE4.x, but I have no confirmation about it.

Has anyone any information about this problem?

Thanks in advance :)

@SardusX86,

 

Your CPU as a minimum must support SSE4 - Penryn and newer Intel processors.  If not, your only hope is for someone to develop a modified kernel (that will bypass the requirement like the hacked kernels for AMD).

 

@legot28,

 

My configuration is normally a MBP5,1 (in config.plist/SMBIOS/"ProductName") but using the Board-ID, MLB and ROM from a MBP6,2 for iMessage purposes - see post#4 and post#5 in @MacPeet's thread.  The MBP6,2 Board-ID is coincidentally in Sierra's compatible list so I had no issues booting back into Sierra after the update finished writing files.

 

If you want to to keep the MBP5,1 Board-ID, you will need to replace PlatformSupport.plist in /Volumes/Sierra/System/Library/Core Services/ with one that contains the MBP5,1 board-id ie Mac-F42D86C8 as described in the above thread.

 

Also, in order to get the App Store to provide future updates, you will need to periodically change your SMBIOS to a Sierra compatible one eg MBP7,1 post#1961.  For owners of real Macs that are not on the supported list, they have reported being unable to get App Store Sierra updates unless they temporarily transplanted their OS hard disk into a supported Mac - see this thread @MacRumors.

So if I could replace the processor with another one compatible with the existing motherboard (socket 775), for example:
Core 2 Duo E7200 / E7300 / E7400 / E7500 / E7600 / E8190 / E8200 / E8300 / E8400 / E8500 / E8600
Core 2 Quad Q8200 / Q8300 / Q8400 / Q9300 / Q9400 / Q9450 / Q9500 / Q9505 / Q9550 / Q9650
this could overcome the incompatibility and I could use an iMac 10,1 definition system?
Thanks again
