Does this mean High Sierra won't work with any of my external spinning disks? That would be a nogo. Or just that the installation needs to be working on an SSD?
I hate having to buy hardware to work with fashionable software.
Cheers,

I am always in the middle of a project. That's the kind of work I do.

I believe HS will install. It just won’t reformat your drive to APFS.

[Robert Withers] "Does this mean High Sierra won't work with any of my external spinning disks? That would be a nogo. Or just that the installation needs to be working on an SSD?"
High Sierra introduces a new filesystem called APFS which is a faster new 64bit file system that is specifically designed to work with SSDs and is already used by iOS. If you have an SSD as your boot drive, it will automatically be upgraded to this new filesystem. If you have an HDD or Fusion drive you will be prompted as to whether or not you want to convert it. This has no negative affects on any previous filesystem drives as they are all still supported. The only scenario that this would affect, is if you "dual boot" from other drives. The older macOS would not be able to read the APFS drive, which is something to consider for people who do this. Other than that, having APFS as your boot drive should have no negative effect. You can still use and format other drives as HPFS just like you always did.

The best advice from that article is one that I always give: Before any OS upgrade, make a clone of your hard drive with Carbon Copy Cloner to an external drive. If everything does go horribly wrong... boot from the backup, reformat and restore your old OS. No harm done (just time lost).

The biggest unknown for Musicians, Video Editors, and Graphic Designers is: Do all of my plug-ins work? I would wait a while for manufacturers to confirm that the plug-ins you care about will continue to work on High Sierra.

Sheesh. I don't know where people get so much FUD from, let alone why people love Apple bashing without any facts to back it up.

Of COURSE High Sierra works with spinning disks. Of COURSE APFS works with spinning disks.

Sheesh.

Don't know that FUD guy. Just asking a question. Will a High Sierra machine boot from a spinning disk or only from an SSD? In other words, would I need to backup on an SSD to get a bootable backup disk?
Many thanks.

Yes, High Sierra will boot from a spinning disk.

If you have an SSD it will upgrade it to the new Apple File System. If you have a HDD it will leave it as HPFS and continue to work as Sierra and all previous macOS's did. Either way it will boot and continue to work.

Will you need to run a 3rd party Trim program with your SSD when you load High Sierra or does it come with it built in?
Thanks!

Jim

[jim brodie] "Will you need to run a 3rd party Trim program with your SSD when you load High Sierra or does it come with it built in?"
It is built-in for all Apple SSD's and the ones you buy from OWC which are supported by the Trim support that is already part of macOS.

This article seems to suggest that as of Mac OS X 10.10.4 Yosemite you can enable Trim for 3rd party SSD's if it's not already enabled.

https://www.howtogeek.com/222077/how-to-enable-trim-for-third-party-ssds-on...

If that doesn't work, you can use something like Trim Enabler from Cindori which I have used to provide Trim support for non-Apple drives but if you have an Apple SSD there is nothing more for you to do.

We just obtained a new iMac with pre-installed OS 10.13.4. and purchased Resolve Studio 15.
Resolve is crashing constantly. (i.e. more than 20 times a day).
I am the DP, and just returned from out of town to discover all this, and trying to help the new editor.
1. Is it possible to install a previously "proven" OS on this new iMac?
2. What "preferences" should be checked?

Thanks in advance for your help.

I'm a duffer but I've been running Resolve 14 on OS 10.13.5 with no crashes. I thought R 15 was still in beta and not for sale.
There are lots of instructions online about how to install pre-High Sierra OS if you have a copy of the OS to install.

I presume you have compared your iMac's specs to Resolve's required specs. I have been running Resolve all along on several machines. Both the App Store version of Resolve 14 and the beta version of Resolve Studio 15. No issues, so I'm not sure what the problem is. For me, Resolve just tends to work. You might check the Resolve Preferences - System Configuration and see what the GPU settings are. It should see 1 GPU only and give you options like OpenCL or Metal. You might want to change them from one setting to another and see if that helps.

Thanks Oliver!

Are any of your machines running High Sierra?

All are currently on macOS 10.13.6. That's the most current version.

Thanks for the response,
My concern was whether a previous OS would successfuly operate the new iMac (purchased two months ago).

I've tried installing older OS on macbook pro's and had difficulty. Is the iMac more forgiving?

tnx
Hal

Usually note. You can try it, but I doubt it will work.

It depends on how much new hardware is in the new iMac. Usually, new OS's have drivers for the new hardware whereas older OS's will not. If, for example, your iMac uses a new GPU for which there are no drivers in the older OS, you will get poorer performance.

The good news is that it's very easy to try this out without affecting your existing iMac. ;-)

Simply plug in an external USB or Thunderbolt drive and format it for Mac OS Extended (Journaled). Then start the installation for the older macOS that you want to use and point it to this disk as the target. You can install any version of macOS that you want on the external disk. Finally, reboot your Mac and hold down the Option key when you hear the chime and after a while you should see all of the available boot disks displayed on your screen. Just select the external drive and your iMac will boot that OS. Then see if everything works.
