Note : Before upgrading to any new or updated operating system, it’s a good idea to have a current backup in place. With that in mind, here are some of the more common problems you may encounter when upgrading to macOS High Sierra. We’re always grateful that new versions of the operating system go through an extensive beta process, but it always seems a few issues will still be lurking, ready to pop up and surprise us.
(macOS High Sierra’s initial install screen.) It endured the summer beta program, and is now available through the Mac App Store for anyone to download and install. If you need any help/hints dont hesitate to get back to us on this thread.MacOS High Sierra is finally ready for release.
So my advice is, while you have time do it, but ensure you make a full backup first with say Time Machine if nothing else (it works), I personally prefer a bootable Clone made with Carbon Copy Cloner. This is an important distinction as prior to macOS Mojave, only SSDs were converted to APFS, and this explains some of the confusion over time regarding how macOS Sierra, macOS High Sierra and macOS Mojave have managed things as APFS has continued to evolve.
More specifically, when Mojave is installed it will convert any internal drive (including SSDs, HDDs and Fusion/Hybrid Drives) from HFS Plus to APFS. Lastly your HFS+ Filing System will be changed to Apple's new (and very successful) APFS System.
You will most probably have to update a few of your existing 3rd party apps, many released new versions if for nothing more than to accommodate the then new Dark Mode Appearance option and System Files Security changes. Mojave does support 32bit apps, it will be the last macOS to do so and it runs them perfectly on my 2015 MBPr. (It will probably come back but not for a while) Personally i would reccomend upgrading to Mojave while you can because it will disappear from the Mac App Store after the release of Catalina if Apple follows its usual practices. I encountered this issue after upgrading an iPhone iOS only to find i could no longer sync it with my laptop without upgrading the macOS. Or because updated devices become incompatible. Apple now only supports the current and two previous macOS versions which means with the release of Catalina Sierra will become unsupported. Either because the older macOS versions become unsupported, meaning that they no longer receive security updates making them increasingly less secure online. I think that overall it's inevitable that we all must eventually upgrade. Thus you're working in an "OS environment" that relatively speaking.is not all that great.and will only get better by upgrading to almost anything newer. In fact.macOS Sierra (the OS version you're running now).was actually considered to be a pretty "crappy" macOS version (compared to the previous OS El Capitan for example). But honestly.there really isn't that much controversial about these 2 OS versions. and new macOS "Catalina" will very likely be released in about 2 monthsĬontroversial aspects regarding High Sierra or Mojave is sort of "old news" now. macOS Mojave was released almost 1 year ago macOS High Sierra was released almost 2 years ago Looking at things from a different point of view.how about newer versions of the macOS introducing highly favorable new features and eliminating negative aspects of the previous older OS versions. Click to expand.There's probably never been a computing OS version released (Apple, Windows, or otherwise).that some segment of the computing population didn't like something about it.
