Problems with updating to El Capitan
XEl Capitan is Apple’s upcoming version of OS X, due to be released in the autumn. But Apple’s public beta program (beta.apple.com) means anybody can install OS X El Capitan right now.
Installing the beta version of OS X is a double-edged sword. It isn’t finished yet, and there are problems being reported with Aperture, Disk Utility, iCloud Keychain, iTunes, Mail, networking and language settings. That’s enough to give even seasoned developers a headache.
These gremlins are likely to be fixed for the full release, but even when the final version of OS X El Capitan is released, we urge caution before upgrading. Development problems will be long gone, but there may still be issues with third-party software. Even major apps, such as those made by Adobe and Microsoft, have been troublesome in the past as they struggled to adapt to Apple’s release schedule.
El Capitan could exacerbate this with a new feature called System Integrity Protection (SIP). This new feature prevents programs from making changes to key OS X system folders. This protection even applies if you are using the ‘root’ user account, which is why SIP is often called ‘rootless’.
As a general rule, if you have to ask: “should I update to the new version of OS X?” then the answer is probably “no” – at least not until a couple of weeks have passed and you can see what problems are being reported.
