Hi!

 

I have an Early 2009 iMac now using El Capitan.

 

I read that I can install Sierra if I do this:

 

OS X 10.11 "El Capitan" officially, macOS 10.12 "Sierra" unofficially with Sierra Patcher

 

Things you'll need:
-A copy of the macOS Sierra Installer App. This can be obtained from the Mac App Store using a machine that supports Sierra, or if you don't have one, you can download a copy here
-A USB drive that's at least 8 GB in size
-A copy of the tool - Download here (Current version: 4.2.3)
*View changelog and download older versions here

 

I found this info here:

 

https://en.wikipedia...)#Aluminum_iMac

 

I compared the supported card in System Preferences under Network, Wi-Fi, Interfaces, en1 and I have "Airport Extreme (0x14E4, 0x8E)

which according to this info, is supported on my iMac.

 

I have an 8 GB USB drive.

 

It looks like I have what I need to do it.

 

Does anyone know if this is safe to do?

 

Thanks in advance for any help.

Hi,

 

in regards to my post above, because I have an early 2009 iMac, El Capitan is the maximum OSX that I can install.

 

I had not mentioned that important info. :upset: My apologies. Otherwise, I could easily install Sierra.

 

That is why I posted the info about a way that I could upgrade my OSX, to see if this is a way that I can do it.

 

With that said, anyone know of what I wrote about above and if it is OK to do it?

 

Thanks
