    You are absolutely correct, Harry.

    In fact, just today, my SuperDuper! app was updated to be compatible with macOS High Sierra. Further, I have been in correspondence with SD's developer who was extremely helpful, polite and reassuring.

    Nevertheless, as you say, a time will come when it will have to become 64-bit.

    Apropos to the above, I was wondering about CCC (Carbon Copy Cloner) - I'm now on v. 5 - below is just a portion of the Blog discussion HERE, which was updated today - appears that those using the app should be fine, but any comments would be appreciated. Thanks all - Dave

    Can CCC make a bootable backup of an APFS volume?

    Yes. Both CCC 4 and CCC 5 can make bootable backups of APFS-formatted startup disks, however there is a limited amount of support for APFS in CCC 4. CCC 4 can make a bootable backup from an APFS-formatted volume to an HFS+ formatted volume, and can even create a recovery volume on that HFS+ backup disk. CCC 5 can make a bootable backup from an APFS-formatted volume to an HFS+ formatted volume or to an APFS-formatted volume. CCC 5 also supports APFS encryption (e.g. CCC 5 can unlock and mount APFS-encrypted volumes during a backup task). Naturally any additional support that we can provide for APFS will be made within CCC 5; new features and functionality will not be added to CCC 4.

    As I said, High Sierra is likely to be the last version of the MacOS that supports 32-bit. That means that there will be a year or more before folks have to be terribly concerned about which applications they rely on that are 32-bit and which need to be upgraded or replaced. For now it's good to take stock of one's 32-bit applications and keep track of their development during the coming year. Maybe even touch base with their developers to let them know that there is a general concern.

    But there is no reason why folks have to start rushing right now to replace their 32-bit applications. There is plenty of time for developers to release updates. And it certainly isn't helpful to start advocating that people move from their favorite apps to ones that others like best by fomenting paranoia.

    Randy, reading SuperDuper blog this week, they believe sometime during the life of macOS High Sierra, 32bit will be killed off somewhere around, or after, OS X 13.3/4.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    I won't be rushing anywhere for quite a while macOS wise, but I was a bit surprised when I was checking on my installed 32/64-Bit apps that my DiskWarrior v.4.4 was still 32-Bit.

    But, as mentioned, not to worry.

    Hmmm…??? Wasn't that MAD Magazine's Alfred E. Neuman expression, or maybe that was "What, me worry?" Same thing.

    EDIT:
    It appears that DiskWarrior v. 5.0 (Dec '14) is also 32-Bit only.

    EDIT II:
    Well, according to their site v.5.0 is 64-Bit:
    https://www.alsoft.com/DiskWarrior/upgrade.html

    That makes more sense, and some other sites need to update their app derscription info.

    I haven't heard anything like that. And...it also makes little to no sense. Making a major change like that in the middle of the run of the life of a major version of the MacOS, with no warning to users, is to invite outrage from millions of users, and some very nasty lawsuits.

    I'll wait to hear something like this from Apple before I take it seriously.

    I believe I recall reading that Apple will no longer accept any 32-Bit new or updated apps after around early 2018, which seems to be amounting to "killing it off" to me, or at least as far as Apple is concerned.

    I've read the same thing but that does not amount to your 32 bit apps will not work after 2018. Like Randy said and like Macworld and MacLife magazines have reported, the next version of macOS (whatever it's named) will not support 32 bit apps.

    We have seen Apple do the same thing with iOS. As soon as you upgrade to iOS 11, all 32 bit iOS apps will be removed from your iOS device and can no longer be added. I'm not sure how many of those I have but I know of at least one: the Mac-Forums app.

    Exactly. At some point Apple will stop accepting new 32-bit apps for inclusion in the Mac App store. That isn't the same thing as 32-bit apps suddenly not working under High Sierra. 32-bit apps will always work under High Sierra.

    The fact that SuperDuper! - and indeed other 32-bit Apps - will still work if I were to upgrade to High Sierra is a great relief.

    Whether either of my Macs would run High Sierra is a different question. Pretty sure my old iMac will not and I doubt that my MBP (mid-2012 iirc - the last one with the DVD drive) will do so, although they both run El Capitan. I think the MBP will run Sierra.

    Yes, your MBP will run Sierra (and High Sierra), but only if you download Sierra now, before High Sierra comes out on Tuesday.

    Please backup. Everything has a life cycle, unexpected and warning free. Nothing will last as long as you want it to.

    That's a good valid point Bob, especially if Apple is going to carry on with their current restricted upgrading method.

    For those in doubt, lot's of pages out there such as this:
    MacOS High Sierra Compatible Macs List
    http://osxdaily.com/2017/06/06/macos...tibility-list/


    PS: A Sierra OS install doesn't appear to be a requirement for installing High Sierra. And no doubt, one can probably skip an OS version or two if needed to get the High Sierra version.

    And for those of you who are contemplating the upgrade to macOS High Sierra - even more so for those with Fusion Drives who have been testing the beta version - have a read of this article, just posted:

    Thanks for that Ian. And a very stern warning from the article and Apple stating that you should backup your Fusion Drive, reformat it to HFS+ and then restore from the backup. It looks like Apple may have discovered some glitches with APFS and Fusion drives.

    Impatient IT/IS guy
    I read this and agree with most of your points and found it to be very informative. This is also my first post

    Right after I read it though, I signed up for the beta and installed High Sierra. I'm currently writing this on my 2017 MBP 13 Kaby Lake i5 w/ touch bar. High Sierra is running flawlessly at the moment. I haven't noticed anything that needs to be fixed but I also haven't delved really deep into the OS. I checked my critical apps, Office apps, Time Machine, etc. and once I verified that they worked, I stopped worrying. I did have a Time Machine backup and a USB with Sierra on it just in case.

    I bought my MBP about 2 weeks ago and got everything organized from my Windows PC and moved over. So I didn't really have files scattered all over the place and only have applications that I really need for work or downloaded to just play with. This is my first Mac so I decided I was going to go for the beta and if something went wrong, fix it or downgrade. I find it easier to learn when I'm hands on and something needs to be fixed. The problem is nothing will go wrong on this MacBook! This forum has been great for reading about issues that may occur though and I appreciate that.

    Disclaimer: This isn't the workstation for my primary job. It is my secondary job primary workstation but I also keep a Windows laptop up to date and setup as a backup. So I never really risked a financial loss.

    All that to say, I think many people will be fine with the initial release. If you can't have your computer down for a couple of hours then yes, wait. But for regular IT/IS guys like myself, enjoy it! New tech is so much fun!

    More than any past major OS upgrade, I strongly recommend that folks wait for the "point-two" release to upgrade. High Sierra offers an entirely new file system (optimized for SSD's), and with that there is, at least the potential for something to go catastrophically wrong.

    Ironically, beta testers report that the betas of High Sierra showed fewer bugs than most past versions of the Mac OS. But don't let that sway you into being an early adopter. And when you do upgrade, I highly recommend doing a full backup of your data first, and possibly two.

    Just about everything that comes with the OS has been upgraded in High Sierra. All the included apps, the graphics, video playback, support for VR, support for GPU's...everything. It will be a highly worthwhile upgrade when it has been proven to be entirely safe.

    Note that High Sierra is rumored to be the last version of the Mac OS to support 32-bit programs. So, now would be the time to start taking stock of which programs that you have that are 32-bit and to start looking for updates/replacements. (Quicken 2007 is an obvious 32-bit app that many users still have that will need to be replaced.)

    To find which applications you have are 32-bit and which are 64-bit:

    Click the Apple menu.

    Choose About This Mac...

    Click the System Report... button.

    Look down the left hand column to Software.

    Under Software click Applications.

    Wait a bit for the info to be gathered.

    The entire right hand window pane will fill with a list of apps.

    You can raise or lower the "window shade" to make the pane larger or
    smaller by using to dot at bottom center of the pane. Below the
    application list is another pane that will show specifics about the app
    you click.

    At far right in the pane is a column named 64-Bit (Intel). You may
    have to expand the window to see this column.
