Mac OS X El Capitan is the latest version of the Mac OS X operating system. It’s expected to be released 09/30/15. As with any software upgrade, it’s important to perform a few important steps prior to upgrade. Not that any issues SHOULD be encountered as the result of upgrading to El Capitan but it’s important to perform a complete system backup first. I have a Macbook Pro Retina and iMac with Retina 5K Display computer. My iMac is my primary studio computer, so I’m going to upgrade the Macbook Pro first. If issues arise during the El Capitan upgrade, at least I’ve only introduced issues to one of my two Mac computers. Prior to installing Mac OS X El Capitan on either of my Mac computers, I’m going to perform a complete TimeMachine backup to an external hard drive. In addition to that proactive measure, I’m also going to detach my external Thunderbolt 2 hard drive enclosures (where my videos and photos are stored) from my iMac before installing Mac OS X El Capitan. This may sound silly but should an OS upgrade “crash” while in-progress and/or introduce other unexpected issues, it’s important to have a proper backup of all files. The only semi-major issue that I’ve encountered to this day with Mac OS X upgrades was the Mac OS X update that introduced the Power Nap feature. I had to disable Power Nap, so that Final Cut Pro X and a few other applications would function properly. I’m excited to explore the many new features within Mac OS X El Capitan and hopefully it will behave well with my iOS devices that have already been updated to iOS 9.
