To update or not to update....your mac or mobile

Posted in: Apple, Digital Data & Technology Group

You're in the middle of writing a document, drafting an email or simply watching Netflix and up comes a message letting you know there's an update available for your device. Many of us will always click 'later' which can lead to security vulnerabilities being exploited and performance issues affecting usage. Others of us will instantly click 'update' without a second thought which can also lead to problems such as compatibility with both software and hardware.

It's been a busy month, with the release of iOS 9, OS X El Capitan and Android Marshmallow which are all major updates to their respective operating systems, (such as iOS 8.4.1 to iOS 9 or OS X Yosemite to OS X El Capitan).

Our advice

It's always good to be cautious when installing major updates  and to contact either the Help Desk in the Library or your IT Supporter prior to updating, as these are the sorts of updates that can have an impact on the software or hardware that you use.

El Capitan for example requires updated printer drivers which can be found here in order to be compatible with the University's Managed Print Service and Microsoft Office doesn't get along with it very well at the moment either.  They usually take a significant amount of time to install too, so these are the sorts of updates you might want to install at a time that you don't need to use your device.


Minor updates (iOS 8.4 to 8.4.1 for example) are smaller updates (but just as important!) and are not as likely to introduce complications as they are often comprised of security patches and performance enhancements. They will usually take less time to install too! However, if the device is business-critical then we would still suggest to check with us prior to updating. We'll probably tell you it's absolutely fine, but always good to make sure, especially if it's a University-owned device.
