Apple periodically releases software updates for your iPad's iOS operating system ("iOS updates"). These are usually minor updates with little to no impact on how you use your iPad with Green Bits, but sometimes these updates may include new iPad features or changes to the iPad user interface. This type of update is for the iPad itself and is different from updating the Green Bits Register app.
In this article we'll go over important things you should know before updating, when to update, and how to update.
Before updating iOS
iOS updates can be downloaded in the background while you continue to use your iPad.
After downloading, the update needs to be installed. This process can take an hour or more, and you can't use the iPad during the installation process. It's best to wait to install updates overnight or at another time when the iPad isn't needed for making sales.
Before downloading or installing an iOS update, make sure you have a stable Internet connection and that the iPad is plugged in to power.
How do I know when an iOS update is available?
Your iPad will automatically notify you when updates are available, or you can manually check for updates by going to Settings > General > Software Update.
Where can I find more information on specific iOS updates?
In Settings > General > Software Update, if an update is available, select Learn More to read the full details of what's included in the update.
This information is also available on Apple's website, and major updates are often covered in media and tech blogs.
Small updates are released periodically throughout the year, though Apple typically releases major updates in September or October each year. These releases typically include new features and changes to the overall user interface. Major updates are usually denoted by a change of the primary version number. For instance, an update from version 11.3.2 to 11.4.1 would likely contain minor background changes and bug fixes, whereas updating from 11.4.1 to 12.0 contains new features and a reworked interface.
When should I update iOS?
Generally speaking, iOS updates do not affect Green Bits, nor are they required in order to continue using Green Bits.
As such, whether and when to update is largely a matter of personal preference. If your iPad is working fine and you have no reason to update, you can continue using your current iOS version indefinitely.
If your iPad's iOS is several versions old (e.g., you're running iOS 9.3.2 and the current version is 12.0) you may begin to notice degraded performance. Green Bits Support may also advise you to update on a case-by-case basis.
How do I update iOS?
If your iPad automatically notifies you of an update, select Details.
Or, go to Settings > General > Software Update.
If you're ready to update, select Download and Install.
When the update is finished downloading, you'll see a notification that installation is about to begin. If you're not ready to install, select Later.
Select Install Tonight and the iPad will automatically install the update between 2:00 AM and 4:00 AM.
Can I set my iPad to automatically update?
Yes, though for various reasons we generally don't recommend automatic updates.
In iOS 12 and later, automatic iOS updates can be turned on or off in Settings > General > Software Update > Automatic Updates.
Can I revert back to a previous iOS version?
No, at least not without significant effort. Apple does not offer an official process for reverting to a previous version, and Green Bits does not support or recommend reverting.
