To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.
In order to prevent any potential boot-loop or incompatibility issues after upgrading to macOS 10.13.2 (High Sierra) when it becomes publicly available, customers should deploy and upgrade to TMSM 3.0 Agent Build 1119 (released on November 20) or later using the OfficeScan Plug-in Manager BEFORE upgrading to the latest version of macOS. Happily, if you follow Joe Kissell's advice in ' Take Control of Upgrading to High Sierra ' and make a bootable duplicate right before upgrading, you have nothing to lose except perhaps time. That's because, in the worst case scenario, you can always reformat your Mac's boot drive and restore from your bootable duplicate. If you are reluctant to mess with your working Yosemite install, which is quite understandable, you should go with a new install. Get a new drive and try to install High Sierra on it. I don't think upgrading is useful for you since you will probably need to install new versions of your applications anyway.

Check compatibility
If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that your Mac doesn't have enough free storage space for the installation, or that the installer is too old to be opened on this version of macOS.
If you want to check compatibility before downloading the installer, learn about the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan, or Yosemite. You can also check compatible operating systems on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini, or Mac Pro.
