John: April 2015 Archives

Professional video editors should be aware of a cardinal rule.  Do not upgrade your operating system unless you are 100% sure your video editing software is compatible with it. 

This is particularly true with products such as Avid Media Composer, and Pro Tools.  Also, pay attention to the compatibility of 3rd party software and plug-ins.  Just because your editing software may be compatible with a new OS, some of your software plug-ins may not be.

This brings me to my next point.  If you purchase a brand new computer from Apple,  it will probably have the most recent operating system installed on it. This means if your version of video editing software doesn't work on the latest version of Mac OS 'Yosemite', you won't be able to run your software.

Please note: The hardware in a brand new Mac may prevent you from downgrading beyond the previous operating system.  So currently, that brand new Mac you just bought may only allow you to downgrade to Mavericks, and not Mountain Lion.

Fortunately, there is a way to re-download a copy of Mavericks.  You can even choose to partition your hard-drive so you can keep the Yosemite OS, along with Mavericks.  You can then boot between them.

To  perform a downgrade to Mavericks (Mac OS X 10.9) from Yosemite (10.10) you will need the following:

  • *A copy of the Mavericks installer (you can find this under the purchases tab within the App store)
  • A thumb drive or external drive that can be re-formatted
  • Some patience

Okay, ready?  Here are the steps.  You may want to print the steps out.
