Apple Releases macOS High Sierra Golden Master Candidate to Developers and Public Beta Testers

Mine appears to be working. I used the link (same one as you get off the beta.apple.com web page it turns out).

It downloaded and popped up an installer. The installer is now downloading more stuff. It's asking for a restart and I'll check it in the morning.

Thanks again for the tip @mikecwest!
 
The question is, will all the features work?
I am using Sierra on my mid 2011 Mini but can't use the anti blue light feature

Snow Leopard was among the most beloved macOS ever. I don't particularly find High Sierra to be as stable as Snow Leopard, however.

I've used every OS Apple has put out since Mac OS 8. Snow Leopard was, perhaps, the most stable of all of them. I wish they would return to a "when ready" release schedule instead of yearly updates.

Going to wait until .1 due to APFS. There are no user-facing features that are a must-have anyway.



And High Sierra is the last OS to run 32 bit “without compromises.” Probably means warning dialogs in 10.14 and support dropped in 10.15.

As I understand it, APFS is optional, (unlike iOS), but I haven't been part of the beta program this time. But, I may wait, too. I prefer stable OS over the newest features.

It isn't working that way. That is what I am trying to say. It did the download and then nothing else happened. No install, no multiple boots, nothing.

Well, I did nothing different than the last two times but this time the install is going on. Some weird kind of bug but I have no idea how to even report it.

So did anyone else run the High Sierra public beta on a Fusion Drive? If so, is my only solution really to delete all my data? I feel as if I'm not understanding something correctly. https://beta.apple.com/sp/betaprogram/apfsfusion

Yes, I'm running the public beta on a Fusion Drive.

Yes, you're understanding correctly. You'll (we'll) have to erase the Fusion Drive, recreate the Fusion Drive with Mac OS Extended (Journaled) formatting (HFS+), install the OS, and restore your data from backup.

The GM Candidate will not install onto a APFS-formatted Fusion Drive, it will not allow us to create an APFS-formatted Fusion Drive. It will only install to HFS+ Fusion Drives.

A key purpose of testing a GM Candidate is to recreate the conditions the public will encounter. Since the public will only have HFS+ (and will not have the option to create an APFS Fusion Drive), testers have to match those same conditions for it to be a valid test.

I assume that a key part of the beta for 10.13.1 (or 10.13.2) will be the automatic conversion of an HFS+ Fusion Drive to APFS. For that test to be valid, testers cannot already be on APFS.

Well, I'm neither a developer nor public beta tester but I got the HS GM Candidate 17A362a downloaded and installed. Took less than hour for the complete process. Thanks to BobOldeHampsink for the link and another person I forgot who gave the terminal command for the beta access.

Well, even Snow Leopard had this lovely bug.

I agree with the sentiment, but I think Apple will keep doing annual releases because of iOS integration. And iOS is too important/immature not to do annual releases. Both Sierra and High Sierra were light on features (yes, I know HR has big changes under the hood) so I don't think annual releases necessarily means that Apple will release stuff when they aren't ready. They'll just have a smaller feature set.

It's required if you have an SSD.

Does that potentially mean that I could wait till the next version and avoid this? Or am I making too much of this and I should do as you said. Only other issue, is that I still don't follow how to
Download the latest High Sierra Install Assistant from Mac App Store.

Any help would be appreciated.

I guess you could conceivably wait until either .1 or .2 supports APFS fusion drives (assuming that it happens that quickly) - but you'll be stuck on whatever beta you're on now, bugs and all. It's also possible, that even if you do wait, that with whatever changes Apple will inevitably have to make for APFS to work with fusion drives, that the current state of your fusion drive won't be supported - and you'll have to do the above steps anyways.

Moving on from that, what issues are you having getting the latest High Sierra install assistant? Are you running one of the developer betas, or a public beta? If it's a developer beta, login to your developer account and re-download the macOS Developer Beta Access Utility (click the download button next to "macOS High Sierra 10.13 GM Candidate"). If you're on a public beta, technically you don't have access to the GM candidate - but you can click on this link: macappstore://itunes.apple.com/us/app/macos-10-13-seed-1/id1209167288?ls=1&mt=12 which will open the Mac App Store and take you to the High Sierra download page - where you download the entire installer (as if you were updating from Sierra to High Sierra for the first time).

There's no doubt that doing this is a lot of work.

I can't promise what may happen if you simply stay on your current version of the beta until there's a release that again supports APFS Fusion Drives. Maybe the 12.13.x installer will automatically update the formatting of any APFS Fusion Drive it encounters, but maybe it'll still require an erase/reformat in order to get the final, stable release.

To get the installer ("High Sierra Install Assistant"), you have to use the link to the App Store that is provided at the beta web site. It also seems you have to re-enroll your Mac in the beta in order to use that link (the step just prior to downloading the installer at the beta site). But I haven't tried this out myself - I don't have the time to do the whole erase/reinstall/restore process until Sunday.
 
If 17A362A really is the GM, then I will not be updating my other machines, this is even slower at start up than the previous 2 or 3 builds - even after a 2nd shut down
 
I also have a Fusion Drive. I am thinking that if I or others reformat our drives to HFS+ for the GM, would we not have to do it again when the 10.13 comes out officially? We would have redone our APFS formatting for the GM and then we might have to reformat again for the official release. Sounds like some other solution needs to be there or wait for a later release 10.13.1 when everyone with fusion drives would have to be accounted for.

You need to reformat it back to HFS+ and leave it there until High Sierra officially supports APFS with fusion drives. In other words, you won't be using APFS on your fusion drive any time soon (short of figuring out a hack to make it work).
 
Quick question: If I install the current GM candidate (which is still listed as beta on the Apple page when I follow the steps outlined in this thread), am I on the production cycle, or the beta cycle? Also, can I then simply upgrade to the release version in two weeks time?

thanks

Looks like I will stay at my latest beta, which works fine for me, until the next iteration comes out that will not require a HFS+ reformatting. Too bad as we were not informed of this when we had the option of formatting everything to APFS in the beta. Not a major problem at this point. If other solutions come up, we fusion folks will be listening.

I installed High Sierra and found that it didn't update me to APFS. Is this because it's a beta and they want users to be able to downgrade back to Sierra or do I have to convert to APFS manually?

It's not an automatic process, you got to update it yourself.

Before installing I went into Disk Utility and erased the drive as APFS.

Thank you for explanation.

I understand people want accurate colors at all times but I still can see myself using this feature when reading web for example.

But that may be just me, and that's not enough to think about making let alone make this feature.
 
So, what will happen for those of us using this GM, assuming this is the final release, will we need to complete a full re install just to remove the word beta?

Usually you can update from 10.x GM to 10.x.1 when it comes out. All depends on whether bugs are found though. There has though, in the past, been a GM2.

That said, I wouldn't be surprised if this is a fairly close build to the last beta - I've been running it on 2 of my machines and haven't had a single issue.

It's perfect! No problems so far and that's why this GM (or whatever this is cause some are saying is a GM "candidate" and that is strange as well) warning is so weird...

I read there are issues with 1) resuming from sleep mode, and 2) Boot Camp, on some systems with Fusion Drives?

On a 2017 15" MacBook Pro with Touch Bar, it was not optional for me. I never saw any options and it automatically upgraded me to APFS when I installed the GM candidate.

Yes, it was only optional early in the beta cycle. As for GM candidate it's on for SSDs and off for anything with a HDD, at least for now.

Let's not forget that Yosemite had multiple GM candidates.

I missed that bug, as I didn't upgrade until about x.x.3, which was my usual standard for a long time. I used snow leopard 10.6.8 for as long as I could, it was stable.

I did not know that.

So, SSD or Fusion drive people should wait on upgrading to High Sierra for a later update (maybe I'll go back to waiting for x.x.3).
 
Hi everyone, can I just check with someone very helpful, I have Developer Beta 9. Is there an update as my App Store is not indicating that there is?
