Apple released the OS 10.12 update named “Sierra” just a few days ago. I’m getting the question now frequently about this update — is it ok to apply it? The answer is conditionally, “Yes.” Personally, unless there’s a feature I’m dying to have, I wait on updates for a few weeks. Every new software release has bugs that need to be fixed. Waiting a few weeks gives the developers time fix them. But, if there’s something you really want in the Sierra update now, here are some things to keep in mind before you update:
Always be sure to have a very recent — same day if possible – – Time Machine backup of your computer. This is super-important! That way, if anything goes wrong we have a way to recover you data.
We’ve noticed that with the current version of Sierra, when it’s installed it breaks the trust setting for the Securly certificate. So, if you do apply the update, you’ll need to open your Keychain app and reapply the “trust all” status of the Securly certificate. If the certificate is not trusted, you’ll see a lof “connection reset” messages when going to websites. If you don’t know how to do this or get confused, don’t hesitate to contact the technology office for assistance. It’s a quick procedure.
These types of OS updates take quite a while to completely install: upto an hour. So, if you decided to run this update, schedule it for a time when you can be without your computer for an hour or so. The good news is once you start it, it’s largely automated from that point forward. So, you don’t need to be near by or do anything during the installation.
Finally, if you do elect to install this update and find that there are other problems, please let me know so I can share this information with others. As always, if you have more questions or need help, don’t hesitate to contact the me or the technology office.
