Update: latest version now just resets over and over all day. It takes a good 30 seconds and sometimes I have to just disconnect the RDP and reconnect it in order to be able to work again. I really miss the old RDP versions here on the Mac that just. Mac App Store is the simplest way to find and download apps for your Mac. To download apps from the Mac App Store, you need a Mac with OS X 10.6.6 or later.
The App Store only shows updates for the OS you are using at the moment, in your case Yosemite 10.10.5.
If you want to go to another newer OS that is called an upgrade. This can be done through the App Store using the following link.
High Sierra is the last/ newest OS your Mac can use. Scroll down to Section 4 and click on Get macOS High Sierra.
Make a full back up of your Mac before upgrading.
Check to see with the developers of any third party apps you use that there are updates available so they will continue to work in the new OS. Another thing you need to check is if any printers/ scanners etc you use have updated drivers and software so they too can continue to function in the new OS.
