Problems with OS X 10.11 – El Capitan

With every major operating system update from Apple, I publish a short entry over on the DssW blog. The update invariably includes the advice not to update immediately.

Wait! Do not update to OS X 10.11, El Capitan, today.

Every major OS X update has problems. Many lurk unnoticed by reviewers and early adopters. Some, like the network changes in the OS X 10.10 update, only appear when a critical mass of devices are updated.

This year Apple released OS X 10.11, also known as El Capitan. This has not been a good update for me.

I have to update my Mac because I am a software engineer. The products and services I work on need to be developed and tested on the latest versions of the operating system.

A Week of Problems on OS X 10.11

In just the last week, the problems I have suffered include, but are not limited to:

If you have an option not to update, wait for at least the first minor update.

OS X 10.11.1 should be released soon. It is unlikely Apple will fix all these problems soon. It took until OS X 10.10.4 before the last round of serious networking problems were dealt with.
