Reasons NOT to upgrade to OS X El Capitan:
- Your mac is more than seven years old and has 2Mbps memory or below; click on the apple icon in the top left corner; select “About this Mac”; and look for the year and the amount of memory.
- You have a deadline to finish a project or task. Rather wait till your deadline is met, then if you have free time risk a day.
- You do not have the ability to make a backup! Make sure you can make a full backup of all your data before you upgrade
- Check the compatibility of your applications, for example, MS Office 2016 has an issue with El Capitan, wait a couple of weeks for this to resolve itself before you upgrade.
