Apple to End macOS 10.13 High Sierra Security Updates This November

From August 2020

Apple will stop all security updates for macOS 10.13 High Sierra in the fall of 2020. That means if you fail to replace your Mac or upgrade your macOS to a newer version by November, you would be putting your data at risk due to less advanced security. 
 
The following computers cannot run macOS 10.14 Mojave or higher and should be replaced by the end of the year:
 
MacBook Air introduced in 2011 or earlier
MacBook Pro introduced in 2011 or earlier
Mac mini introduced in 2011 or earlier
iMac introduced in 2011 or earlier
Mac Pro introduced mid-2010 or mid-2012 

How do I know what Mac and macOS I have?
 
To see which Mac and macOS you have click on the Apple icon on the top right hand part of the screen and then click “About This Mac” in the drop-down menu.

There it should tell you the kind of Mac you have and which macOS you’re running.
 
What can I do if I’m still running High Sierra?
 
If you have a Mac that is too old to update to macOS 10.14 Mojave or newer, please contact us to discuss your options for replacement. If you can update to Mojave or a newer OS, please consult with us first. We will make sure that any software you are currently using will be compatible with a newer OS.
