Apple updated El Capitan to 10.11.1 in late October, and the OS X 10.11.2 update and should be released in early December.

The OS X 10.11 update fixes the problems I blogged about on 10/14/2015 with Mac Office 2016, Photoshop CC, and Audition CC. The problems mentioned with Adobe CS, Premiere Pro CC, FileMaker, NAS devices, IntelliPoint drivers, and Kaseya still exist.

Although the forthcoming 10.11.2 update will likely smooth over many bumps, I still probably won’t be recommending El Capitan to the masses until OS X 10.11.4 or 10.11.5 becomes available.

MY UPDATED RECOMMENDATION…
For production Macs on OS X 10.9.5 Mavericks or OS X 10.10.5 Yosemite, I highly recommend against end users upgrading to OS X 10.11 at this time. Older Macs running OS X 10.6-10.8 should not be updated, period, unless done so by a qualified engineer.

As a rule of thumb, upgrading from one version of OS X to another is not something I’d recommend in a production environment without a compelling reason or solid upgrade plan. Reasons would include a necessary application that requires a newer version of OS X, security concerns with older versions of OS X, or upgrading all the Macs within a workgroup to keep them consistent for an imaging solution.

Two important tips for early adopters:

  • Make sure that every single application that you use is patched to the latest version before upgrading, and while doing so also verify each application version is compatible with El Capitan. Upgrading OS X, and then dealing with applications not working because they are unpatched or incompatible, is a common mistake leading to hours/days worth of frustration.
  • Make sure you have a full backup of the Mac saved to an external drive prior to upgrading (either with Time Machine or more preferably Carbon Copy Cloner). Upgrading OS X is a one-way path if you don’t have a backup, and those that experience major problems often wish they could just go back to the way things were. Having a full backup makes that possible.
