    I have noticed that Photos on my mac has gotten a little glitchy when editing. The sliders seem to be a bit buggy as if there is a lot of background activity.
    Have you had anyone else have this problem….??

    I’ve been running High Sierra on my 2008 MacPro successfully since October 1st – very stable. Using the patch. No need to downgrade back to El Capitan at all…

    What? no links?

    Using the “dosdude1.com/highsierra” patch.

    Rather than downgrade, FIX your High Sierra installation.

    Downgrade means also you loose ALL your recent work !!

    The only problem I’m having with high sierra is that bootcamp has a new issue – you can’t boot directly back into macOS from windows as windows cannot see the new file system. There’s an easy workaround, and hopefully this will be fixed soon.

    Forget Time Machine a clone is far more accurate and simple to do. SuperDuper or CarbonCopyCloner are well worth the few $$ they cost, and for the typical consumer a far better choice.


    If you have a clone backup, you simply save any new work to a separate drive, boot to the clone and clone the backup to your system drive and you are done. This takes about 1/2 the time it takes to restore from TM and is failureproof.

    However I recommend doing this. Partition your system drive for multiple OSX installations, keep one for your current OSX, and another to install High Sierra. You can then test drive, as I am now, a new OS will continuing to run under the old version. You have access to everything including applications and files, without endangering them to be corrupted or not work under the new OSX version.

    Once you decide all is well and you’re ready to move forward on the new OSX, and have backed up the current version (just in case) you can use Migration Assistant to import your files and user setup to completion, then wipe the other partition and use it for storage until the next OSX update, where you can do this method over again.

    This allows the user to, without endangering any of their current setup, test drive a new OSX version. It requires drive space only, and given how cheap that is, anyone really can afford this.

    it is however not a replacement for backup!!!

      Good advice and I agree with your sentiment.

      I strongly recommend backing up before any system update even the minor ones. Time Machine is good for most users since it is simple, but if you can manage to work with a complete clone of a drive that can be even easier. Cloning drives is particularly great when replacing a hard disk too, both CarbonCopyCloner and SuperDuper are excellent.

    The problem with this article is that – unless I’m missing something obvious – it doesn’t work.

    You can’t reformat the 10.13 drive from the Recovery partition as MacOS X Extended! It tells you the drive is in use.

    Meanwhile it doesn’t want to start up from my SuperDuper backup drive, so I’m off to find the power supply for my retired MacBook Pro to try and start up in FW Target mode…

    Man. I hate the Mac dance.

    By the way, it’s ridiculous that the installer doesn’t ask if you want APFS.

      Of course this works. This is how you downgrade High Sierra by restoring from a Time Machine backup from before updating. You can also start the process from another boot volume if you want to, whether USB flash drive or hard drive. If you want to install Sierra or El Capitan, you have to format the target drive as HFS+ it can not be installed onto APFS.

      You can’t format the drive you are actively booting from, but you can format a different partition. The Recovery partition is one partition, the OS partition is another partition. So if you are booted into Recovery, you can format the OS partition but you can not format the entire hard drive because it also contains the Recovery partition that is actively booted from. To format the entire drive, you need to boot from a separate disk entirely, but that is not necessary simply to restore from Time Machine.

    My only problem with High Sierra is that it does not allow me to play videos from an external dive that are over 1GB without a tedious process of “verifying” which can take several minutes. Is there a fix for this ?

    My only gripes about High Sierra is that it highjacked the only drive I can boot from with the new filesystem.

    I attempted to set up a boot camp after the installation and the disk utility wouldn’t resize the partition on my boot drive. This required a clean install to a pre-install partition created. Of course then there’s the booting back to MacOS from Windows is broken.

    But here’s what really irks me and I hate to catastrophize, why did Apple remove the networking assistant. I use that frequently and two months ago daily.

    I know how to troubleshoot my network using command line tools, but that utility was able I show me exactly where the breakdown was occurring everytime saving me hours of troubleshooting time.

    I jumped on Mac just after the UI turned flat, and everything I always drooled over from Apple seems to be going away.

    Thanks a lot, it worked flawlessly. And I could put back the new documents from the most recent Time Machine backup (high sierra to sierra). So far everything is OK.

    macOS 10.13.1 – I really don’t want to downgrade to macOS Sierra, but I may have to…I have seen that in my user account after about 30min at most, my system will freeze completely. I always keep the time w/ seconds showing and the seconds stop ticking away and the whole system is frozen. Then about 1-2 min later, my iMac reboots. I have seen that this never happens when logged into my other 2 user accounts on my system, so clearly something within my user account is causing his freeze.
    I’ve disabled all login items, held shift down after entering my password at login but it still freezes. What are the paths to the logs I need to examine to figure out what is causing this?

    Thanks. I will be doing this later today. My 15″ MBP with touchbar freezes at least every 1-2 days requiring a force restart. I’m also seeing several glitches with Citrix and displays.

    Kind of reminds me of the OS9 days.

    This method is only useful if you backed up whilst you were still on Sierra – BEFORE you upgraded to High Sierra (as the Author did mention). But for most of us, with Big Brother Apple pushing the virtues of ‘always upgrade to the latest OS’ bull dust.. Experience now tells me to make backups BEFORE you upgrade to their latest and greatest OS, because now that I’ve upgraded to High Sierra, and found it to be too bloated for my Macbook to run, Migration Assistant or Time Machine both won’t allow me to reinstall Sierra and import my old user accounts I only managed to back up while on High Sierra. So.. pretty useless, and annoying that I’ve wasted a week now trying to work out how to go backwards from High Sierra to Sierra, and put my backed up user account from High Sierra on it. No go – will not acknowledge the newer backup. Apple – I HATE you for becoming so non-user friendly now.

    You can bet that Mac are building obsolescence into their applications and software, they have apologised for doing it on iPhones… doesn’t mean they stopped, they only apologised for doing it. Crapintosh at it again…!
