Don't Install if You're Traveling

Don't Install if You're Traveling

Are you currently traveling for work or pleasure? This is not the time to install the macOS Sierra update. No matter how much your Mac tells you that this is the time to install an update -- don't do it.

We've heard from users who decided to install a Mac update in an airport right before a flight and were left without a working computer. The same goes for installing this update in a hotel.

Wait until you have the time you need, are at your home or office with a current backup and then upgrade to macOS Sierra.

    Nothing is perfect and Mac OS Sierra is no exception.

    Actually this article mainly talks about the advantages of the new system. But we can not deny that Sierra also leads to some problems like Mac app damage, Safari crash. This article reveal both the problems and solutions. Hope it will be helpful https://bit.ly/2d3d7gE

      Hi There,

      this post is something we call bait. It suggests on Google Search Results to deal with certain issues. Then when reading the post, it quickly becomes clear that this post doesnt deal with anything of any importance.

    Installed it this morning. I’m now about to uninstall it as there is nothing worth upgrading for. Novelties like Siri and picture in picture aren’t worth the trouble for all the software that Sierra breaks. I’m staying with Yosemite.

      Hello. Do you know if there is a way to uninstall El Capitain and go back to Yosemite ?

      • Parker Tubman

        10/12/2016 at 7:36 am

        There is a way to go back to Yosemite because that is what I did. I did not like El Capitan. Here’s how to do it.

        If you did back up before installing El Capitan … :
        1. First get a hardware drive with lots of memory
        2. Back up your entire computer through Time Machine app.
        3. Then when you upgraded Yosemite, go on to Time Machine with your hard drive attached to the USB point on the computer, and select the last backup file with the date that you did the last backup before El Capitan came on your computer. It will have Yosemite on it.

        If you did NOT back up Yosemite before installing El Capitan … :
        1. First get a hardware drive with lots of memory
        2. Go on to Time Machine with your hard drive attached to the USB point on the computer, and select the last backup file that you did on your hard drive. If its something older an Older OS system on there you can choose that and not have El Capitan anymore.

    Lol….early adopters with “Software Update OCD” always get screwed, and yet they never learn….. Just because an OS is released today, doesn’t mean you should immediately install it thinking it’s going to somehow make your computer “better”, or “faster”, ideas of “update” is in your head. Stick with El Capitan, it’s rock solid; as with any OSX update, it’s _ALWAYS_ wise to wait for the second incremental (i.e 10.12.2) patch before even considering upgrading.

  9. Zac Paul

    10/01/2016 at 12:37 pm

    WHAT IS THIS? This article really misses some significant points. And when I say “significant points”, I mean almost every point of meaning.

    THE BIGGEST FEATURE OF SIERRA, WHICH IS GOING IGNORED BY MANY PUBLICATIONS
    The biggest single upgrade with Sierra is the pending APFS, Apple’s new file system that will replace the two-decade old HFS+. This is a massive undertaking. You can ONLY upgrade to APFS with Sierra, and you WILL be able to upgrade file systems WITHOUT having to do a clean install. Right now, early 2017 is when APFS should be pushed to general users. This file system has better data integrity, better multi-tasking abilities, is optimized for high-speed flash storage, and offers MAJOR improvements in encryption options. In the future, by using APFS on OS X, this will allow OS X to have a degree of interaction with iOS that was never before possible (currently, as iOS uses APFS, and Mac HFS+, there are some compatibility issues between Macs and other Apple portable devices that APFS can lift.)

    BRAND NEW OPERATING SYSTEMS ARE ALMOST NEVER AS SECURE AS THE MATURE PLATFORMS THEY REPLACE.
    As for security, expecting a brand new OS to immediately be more secure than a mature platform is a risky assumption. Beta testing has the limitation that the quantity of beta testers are a tiny fraction of real-world users of the stable version, so beta and pen testing provide valuable data, but there are limited. Apple, like Microsoft, doesn’t drop support on one version of OS X the moment the next comes out. The security flaw you are referencing IIRC has been pushed out to all versions of OS X dating back to Mountain Lion. As of right now, the XTS-AES whole disk encryption used by FileVault2 is secure on all recent implementations of OS X. When Sierra gets APFS, users will have more encryption options, and the potential for greater security. As for general usage, the greatest security vulnerabilities are usually attacking add-ons and extensions in browsers (such as Flash.) Using a modern browser, keeping it updated regularly, using a site like SSL Labs to test a website you are about to buy from but want to know if they use good cryptography. Users worried about security and privacy should consider Little Snitch, Murus, BitDefender, 1Password, good password habits, encrypting internal & external drives, as well as flash & SD cards & drives, and ensuring their use of cloud computing is secure. No operating system can compensate for bad security habits.

    FIX PROBLEMS BY FINDING AND RESOLVING THE ACTUAL PROBLEM!!!
    Doing an in-place OS update on a malfunctioning system is like replacing your brakes if you need new tires and hoping that things turn out OK. If you are having problems with a current release of El Capitan, it is unlikely that upgrading to Sierra will fix this and it increases the chance that you screw things up even worse than before. Think about that for a second…you are having issues with a mature operating system that has proven reliable, so you upgrade to a new one with far less known? El Capitan is an extremely reliable operating system…if you are having an issue, you need to determine if it is related to the OS, Apple software, 3rd party software, or hardware failure because the course of action to fix the issue is completely different. A free program such as Onyx can fix many OS issues, and along with utilizing Disk Utility, resetting PRAM/NRAM/SMC, Apple’s hardware testers, and a utility that pulls SMART data from the local drive, you can get a good idea of what is going on and may be able to fix it. If there are issues with severe disk corruption, upgrading without a clean install will not do a thing, and the only application that reliably repairs severe corruption that even OS X itself cannot is DiskWarrior.

    OVERALL, THIS MINOR UPDATE HAS BIG POTENTIAL
    Functionally, Sierra is not currently all that different from El Capitan. As El Capitan is extremely reliable, this makes sense so Apple has a solid base for the OS leading us to APFS, where a mid-life update (or what replaces Sierra) may then implement larger changes that makes the interaction between different devices a far better process, with greater ease and improved productivity. Apple also likely realized that with such a rapid update schedule, minor changes to OS X are better than radical changes because reliability suffers with changes as such. Leopard, Lion, (and Mavericks and Yosemite to a lesser extent) all introduced awesome features but had a lot of issues. Snow Leopard, Mountain Lion, and El Capitan introduced few new features and instead vastly improved reliability.

    MAKE A CLONE BACKUP IN ADDITION TO OR IN PLACE OF TIME MACHINE
    Before updating, I advise having a CLONE (not a TimeMachine backup) of the disk you are going update. A program like Carbon Copy Cloner makes a superior backup and one of the optimal quality desired should you need to revert back to your older OS without doing a fresh install. Clones can be made bootable, where Time Machine cannot.

    USING VIRTUAL MACHINES TO TEST NEW OPERATING SYSTEMS SAVES A LOT OF CUSSING TIME
    If someone has compatibility concerns, consider purchasing VMWare Fusion, Parallels, or downloading a free player. These virtual machine apps allow you to run Windows, Mac, Linux, etc. operating systems on your Mac in an isolated environment. You can then ‘test’ the new OS to ensure it works reliably enough for your needs and has no issues with your older Apps. The $100 or so spent on this software can save a ton of grief, and many hours of your time by preventing you installing an OS, finding it doesn’t work right, and then manually having to downgrade (which still may have issues.)
    —-
    So, should someone update to Sierra? As of right now, my opinion is…

    YES, if:
    -the need to have the latest-and-greatest ASAP is more important than reliability, compatibility, and security
    -you want to immediately benefit from improvements made with iCloud
    -you strongly like the updates to Mail and Messages (IMO they are very minor compared to iOS10)
    -you love Siri and feel it will be useful for you with your desktop/laptop
    -you frequently use multi-monitor displays with a MacBook Pro

    -you want to take advantage of the benefits of APFS (this will apply sometime in early 2017)

    NO, if:
    -reliability is the single-most important thing to you (wait until 10.12.1 or 10.12.2, as these updates always address the most significant issues of the first release.
    -security is the single-most important thing to you (wait a bit, same as above.)
    -you use a lot of older software that is no longer supported by the Maker(s)
    -you are not comfortable manually downgrading the OS should Sierra not work well on your machine (also wait a bit.)

    Major regrets installing this upgrade. My external harddrive is now “read only”. I can’t export any photos to it from lightroom. I have tried changing permissions, etc. with no luck. It won’t let me. Wish I had stayed with Yosemite as I have many many photos to get to clients. Put me in the unprepared column. So discouraged. I guess I’ll have to purchase new external hard drive.

    Hi guys,

    I have OSX Lion, and every time a new upgrade comes out I am very reluctant to upgrade to them, and had no issues with my old Lion. Two weeks ago I updated my iPhone 5 and now my photos won’t sink into iPhoto in Mac. I tried unlock the iPhone as the popup window would ask, but nothing happened. I called apple support and they told me to upgrade the software to Sierra. And again I don’t want it especially after reading above comments. So I wonder if anyone knows the way to transfer iPhone pictures to Mac?

    macOS Sierra is a disaster. I upgraded my 2014 MacBook Air, and have spent 3 totally unproductive days trying to get basic tools that I count on every day to minimally work. To no avail. The Apple phone techs are useless. There are no “geniuses” at any ‘Genius Bars’.

    macOS and Sierra are enhancements for toys, not real-life business tools. If the concept of ‘planned obsolescence’ is now the center of Apple’s marketing plan, then I will end my 30+ year reliance Apple products and buy elsewhere.

    Sorry I ever bought an Apple in the first place.
    (Had early problems with key board on BookAir, replaced x2)
    As for Sierra, nothing seems to work with it i.e. Browser (neither Chrome nor Firefox) Outlook, and most prominently the Parallel Desk (with Win10), even though have updated to latest Parallel. Everything crashes, impossible to complete even this note, .. inordinate frustrations, in trying to remedy things with relatively mediocre skills, but otherwise quite apt, for a non-geek, and it would be certainly insolent of this company to expect me to be under the hood all the time. My cry ought to be seen as an indictment of this Apple Company which is overall sloppy in releasing stuff like this, frivolous and mostly dedicated to ‘social toys’, inconsiderate, and ultimately unserious.

    MY concerns with these additional features that Apple so enthusiastically offers are that I have a Macbook Pro mid 2012 machine and it seems to be the general consensus that Apple are deliberately trying to make any machine that is 4 years and older obsolete by deliberately slowing its processing speed down where it becomes unusable which therefore encourages the user to go and buy a new and latest version of the macbook pro. Thoughts on this anyone? (not Apple obviously)

    It’s a useful article – maybe not if you want Rules Handed Down from On High, as it doesn’t do that – it just outlines some problems, some advantages, and leaves it up to us to decide. Fine by me.

    Me? Oh, I’ll stick with El Capitan for now, for a few months, and see how things pan out. That’s the technique I’ve applied to the past few updates!

    Cheers.

    Apple seem to be falling into the Microsoft trap of updating and releasing software updates before they are fully tested, ISO 10.12.1 has brought several problems that were not needed or wanted, Photos CUP usage 100%, why do this??

    After installing new MacOs Sierra 10.12.2 I had problems with Safari freezing, when going into Activity Monitor the CPU was up loading fast and memory going over the roof some thing in the background was running fast (but slowing the computer) could not be found why. The wi-fi disconnecting and asking for password , as well as a very slow computer. iPhoto download once iPhone connected had to be download automatically with editing a manual response. I have now switched back to Yosemite and no problems and quick and easy and a fast internet once again. No thanks to Sierra too many problems to thrash out.

    There is a way to get Yosemite back from Sierra as follows:

    There is a way to go back to Yosemite because that is what I did. I did not like Sierra. Here’s how to do it.
    If you did back up before installing Sierra :-
    1. First get a hardware drive with lots of memory
    2. Back up your entire computer through Time Machine app.
    3. Then when you upgraded Yosemite, go on to Time Machine with your hard drive attached to the USB point on the computer, and select the last backup file with the date that you did the last backup before Sierra came on your computer. It will have Yosemite on it.
    If you did NOT back up Yosemite before installing Sierra :-
    1. First get a hardware drive with lots of memory
    2. Go on to Time Machine with your hard drive attached to the USB point on the computer, and select the last backup file that you did on your hard drive. If its something older an Older OS system on there you can choose that and not have Sierra anymore.

    Worked for me! Happy as back with Yosemite!

    I have a REALLY GREAT late 2012 iMac 27″, 3.4 GHz Intel i7, 16 GB RAM, 1 TB Fusion drive, NVIDIA GeForce GTX 675MX 1024 MB, OSX 10.9.5 latest

    And Apple replaced the display FREE last Feb 2016 due to a minor blemish.

    But NVIDIA are not updating the drivers for 3D and so if I update to Sierra, and run a 3D app, CRASH. No way around it.

    There is also a problem with compatibility with third party equipment. Canon pro inkjet printers are only compatible with 10.12.1. Unfortunately I bought a new retina MacBook Pro and it came with Sierra 10.12.2. There is no way, within apple techsupport to roll back to 10.12.1 so right now I have an expensive paperweight until canon updates their drivers.

    Very disappointing update. I wish I’ve never done it. It conflicts even more with gcc (when clang is shit! and one can’t do a thing with it) and creates issues with creating local hosts to run notebooks. I’m really considering on going back to linux
