Check compatibility

You can upgrade to OS Yosemite on any of the following Mac models. Your Mac also needs at least 2GB of memory and 8GB of available storage space.

Mac mini introduced in early 2009 or later

To find your Mac model, memory, storage space, and macOS version, choose About This Mac from the Apple menu . If your Mac isn't compatible with OS X Yosemite, the installer will let you know.

Before you leap from Yosemite, check the specific printer/scanner vendor driver sites to verify if either have High Sierra driver support. Also check with your third-party applications vendor sites that their applications remain compatible with High Sierra, and preferably, are 64-bit applications. Although the vendor sites are the last word on application support, you may find RoaringApps helpful too.

I would also recommend the following:

1. Download and run the free Malwarebytes for Mac before any upgrade to see if any malware presently exists on your Mac, and if found, can be removed. Subscription for continued realtime features is purely optional.
2. Boot into Yosemite Recovery (⌘-R) and run Disk Utility First Aid on your startup drive.
3. Perform one last Time Machine backup before the upgrade.
