Apr 21, 2018 Canon recommended upgrading MAC OS 10.9.5 Mavericks to at least MAC OS X 10.10 Yosemite. Below is my response with some instructions. Usually, upgrading your MAC OS does not affect your personal files. However, you can back your data manually to an external hard drive or USB flash drive. Also, you can create a Time Machine backup of your computer. Currently Up-to-Date Version: Mac OS X 10.9.5 (UniBeast Method) This guide is all about installing OS X Mavericks on your hackintosh. If you're looking to install an older version. Jan 26, 2017 The free download for Antivrus from C-Net requires OS X 10.8 or later. Can I get a download from somewhere else which runs on 10.7.5.And when I dow. But if you want to stay secure on OS X 10.9.5 Mavericks, you need to STOP using that 3-4 year old version of the Safari Web browser and switch to a Web browser that is up to date, like Mozilla Firefox OR Waterfox. Good Luck to You! My hard drive died so after I had a new one installed, the Apple Store loaded Mac OS X 10.9.5. When I tried to re-load my Mac Office 2011, it wasn't supported. I have tried to download Mac Office 2016 and even just Excel 2016, but both need Mac OS X 10.10. I am stuck between Mac Office 2011 and Mac Office 2016 because of Mac OS X 10.9.5.
