- Question: Q: Can't update past El Capitan I own a MacBook Pro mid-2009. I haven't been able to update my OS past El Capitan and I'm worried about security updates that aren't being addressed by running an older OS.
If you have a mid 2009 MacBook Pro, you can't update the OS. To update, you need a MacBook Pro (Mid 2010 or later) Model 6.2 and higher.
Jul 18, 2016 This update is recommended for all OS X El Capitan users. The OS X El Capitan v10.11.6 Update improves the stability, compatibility, and security of your Mac, and is recommended for all users. This update: Resolves an issue that may prevent settings from being saved in accounts with parental controls enabled.
If you are careful about what you download and where you search on the Internet, your computer is useable without the latest security updates. My last computer had a 10.6 partition which I used every night. That was after El Capitan was released, so the OS was 5 versions behind. By being careful, I never had any problems.
El Capitan Software Update Not Working
I would make sure that you had at least 2 separate backups on 2 separate drives in case you have problems. That will allow you to recover.
