I stayed a long time with Mountain Lion on our MBP 2011 and 2012. They have all SSDs (Samsung 840 and 850 EVO) NO NEED AT ALL to buy a younger MBP than Model of 2012 as they got very fast with the SSD and you can still upgrade MBPs before Model 2013 yourself easily to SSD, install a new battery and (my recomendation) also upgrade your RAM to 8 GB (which does not cost much as well). Upgraded to ElCapitan some months ago. El Capitan runs perfectly on our MBPs 2011 or 2012, even a MBP 2009 runs well with it! You will be very happy with it. My advice to protect your dGPU:.

Upgraded my 2011 and 2012 MBPs 2 months ago with OS Sierra - works very fine, no problems at all. For me, they seem even to be faster on Sierra. Using SSDs since years, having upgraded the RAM (8 or 16 GB) both MBP feel like new machines. Works very fast and smooth. Be aware of the fact, that after switching to Sierra your system will work for many hours depending on quantity of data - maybe even a whole day - as hell. Don´t be desperated - this is normal and will stop once this initial reorganisation of the system has been finished.

Mac OS X Lion (version 10.7) is the eighth major release of Mac OS X (now named macOS), Apple's desktop and server operating system for Macintosh computers. A preview of Mac OS X 10.7 Lion was publicly shown at the 'Back to the Mac' Apple Special Event on October 20, 2010. Sep 13, 2011  MAC mini 2011 model wchih came with LION preinstalled. Wanted to reset it back to the Factory setting as given in the document provided. From the Mac OS X Utility. Erased the Hard drive as specified from the Disk Utility. Selected Install a new copy of Lion, which starts a download of about 3.76 GB and displays 5Hr 50Mins pending to.

2009 and 2010 MBPs are limited to ElCapitan. But they run flawlessly with ElCap.

To make the deal even sweeter, LibreOffice recently added an online component. Microsoft excel software for mac. So you can sync files from Google Drive or OneDrive and edit then right in LibreOffice (there’s no collaboration feature, though).

It used to be that to have remote control ability on Mac OS X it took third party applications. In Tiger they introduced a built in VNC server which is convenient. Now in Leopard, they include a built in VNC client called “Screen Sharing.” This is actually the application that is used for “Back To My Mac” or to “Share Screen” with local machines on your network.

But, it can also be used as a VNC client to any machine. It’s probably most convenient if you take the app and put it in your Dock.

It’s located in /System/Library/CoreServices/Screen Sharing. There are also other ways to open the app on demand. In Safari, you can type “vnc://ip_address” in the URL bar, replacing “ip_address” with the actual address of the remote Mac.

In Finder, you can “Connect To Server” (Commank+K) and type it there as well. Doing either of these things will open the application, begin the connection, and return asking for your login.

(Of course, to have any of this to work, you’ll need to be sure to have either “Screen Sharing” or “Remote Management” activated in your System Preferences -> Sharing panel.) Posted on Author Post navigation.
