You will need to upgrade to El Capitain (OS X 10.11) first: https://itunes.apple.com/app/os-x-el-capitan/id1147835434?mt=12

After that you might be in a position to upgrade again depending on your hardware.

If you machine can not run High Sierra (macOS 10.13), https://support.apple.com/kb/SP765?locale=en_US

you will be presented with Sierra (macOS 10.12) https://support.apple.com/kb/sp742?locale=en_US

Start with the >App Store

How to download macOS High Sierra

You can upgrade to El Capitan from Lion or directly from Snow Leopard. El Capitan can be downloaded from the Mac App Store for FREE.

To upgrade to El Capitan you must have Snow Leopard 10.6.8 or Lion installed. Download El Capitan from the App Store. Sign in using your Apple ID. El Capitan is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

Macs that can be upgraded to OS X El Capitan

1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later

2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later

3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later

4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later

5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later

6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later

7. Xserve (Early 2009) - Model Identifier 3,1 or later

To find the model identifier open System Profiler in the Utilities' folder. It's displayed in the panel on the right. Are my applications compatible? See App Compatibility Table - RoaringApps.

I have no idea what MacSienna is.

Maybe if you told us exactly which model of the Mac you wish to upgrade, we might be able to help you.

Please include the model number, amount of RAM and amount of free disk space.
