Does anyone know of any issues with this before I press the button?

Have been on it since beta 3 or something. This has been one of the more smooth transitions, no dev tools broken, and only few apps had some quirks that I filed bug reports for, which are now fixed.

The APFS change really isn't something you are likely to hit, heck you'd have to go out of your way to make it a problem.

Deffo recommending it :) Speed ups are nice!

Speed ups? Where are you seeing speed ups? I'm on a Macbook (last gen) and have been using High Sierra for the last month or so. Aside from my changed desktop background, I haven't actually spotted (any / many?) changes.

General animation things because of Metal 2. APFS is awesome when copy pasting (instant), Safari's faster, and general performance increase (subjective of course).

There are tons of small changes here and there!

What does a filesystem have to do with copy-pasting?

I think he meant copy-pasting files.

Yes, according to the Apple page:

>Responsive. Designed to make common tasks like duplicating a file and finding the size of a folder’s contents happen instantly.

Yup, which is pretty neat. Before you'd have to wait for the little Finder window to show up, calculate time remaining and then do the job. Now it's instant when copy-pasting files around :)

Do you know if the APFS conversion affects Bootcamp at all?

It doesn't, it only touches the drive you perform it on (meaning your Mac HD). I literally did a fresh install yesterday with an existing bootcamp partition, and no problems.

One thing though, if you relied on some thing like Paragon or whatever to read your HFS drive, that will obviously not work anymore (not personally a problem, but could be a deal breaker for some).

If you're using VMware Fusion then your Bootcamp partition currently appears to be not accessible.

So it looks like that the conversion does confuse VMware Fusion at the moment. Not aware of any other issues with Bootcamp.

One of my guys ran into https://github.com/hashicorp/vagrant/issues/8788 - it was hellish trying to figure out what was happening.

Thanks for the heads up. I was considering using vagrant on this box. I'm currently RDP'ing into a windows box in the office and using that for vagrant most of the time at the moment.

I would wait at least a couple of weeks until all the quirks are ironed out.

Especially if you're a programmer, allow a little time for all the apps to catch up and update their versions.

High sierra comes with big changes like the Apple File System, and I'm sure there are a lot of stuff going on under the hood.

Yup, it's a well established truism at this point that if you need a stable system (or don't have excellent data backups) you should never install the .0 version of any Apple OS. And while many Cocoa apps should be forwards-compatible out of the box, if you rely on Homebrew it may be several months before the packages you need are all updated.

Obviously just 1 data point, but I've been on High Sierra since the GM candidate came out. Smooth transition - everything just worked. Nothing about my development setup had to change.

if you rely on Homebrew it may be several months before the packages you need are all updated.

A large part of software in Homebrew is already pre-compiled (bottled) for High Sierra:

    % find Formula -name '*.rb' | wc -l
    4363
    % find Formula -name '*.rb' -exec grep "sha.*:high_sierra" {} \; | wc -l
    3634

Most of the stuff that I have been installing the last one or two weeks was installed as bottles.

Good to know!

I’ve got a spare machine and will run it on first. I don’t do any dev on the box; it’s all remote. I use git client and macvim to update some markdown docs occasionally but that’s about it. Rest of it is on the end of SSH and via web.

You should be more than good to go then! Git and vim/neovim/macvim runs like normal. This has been one of the least dev burdensome updates in a while.

beta has been public for like 3 months, most apps have updated already.

You won't be able to connect to a shared drive using AFP anymore, if you get the new file system APFS when you upgrade. Apparently you only get APFS if you have a pure SSD drive (not Fusion).

https://support.apple.com/en-gb/HT208018

  APFS and file sharing
  - Volumes formatted as APFS can't offer share points over the network using AFP. 
  - APFS supports SMB and NFS, with the option to enforce only SMB-encrypted share points.

> You won't be able to connect to a shared drive using AFP anymore, if you get the new file system APFS when you upgrade

Not quite. You can't share your drive over AFP if you've formatted it as APFS. Connecting to a remote AFP share is unchanged.

So I read the note you quoted as "an APFS filesystem can't be exported over the network via AFP", but what you wrote seems to say "a machine running the APFS filesystem cannot mount an AFP exported filesystem".

I don't think your conclusion is supported by the snippet you quoted.

Do you really have the button? I saw this headline and tried to update the Macs I have that are waiting for this update, but none of them see it in the App Store.

And the page linked still says, "Available 9.25".

You can try some tricks from here https://appletoolbox.com/2016/11/macos-app-store-updates-not....

Namely, try going to System Preferences -> App Store and press Check Now.

Not yet. I assume it won't appear until this evening for me. I like to think ahead :)

I can confirm that – I also don't yet get the update

Yep nothing exciting happening here yet. I'll wait until this evening.

The Pacific Timezone (PST) is currently in the middle of the night; I suppose we have to wait for them to wake up.

Homebrew often seems to have important packages break with each major macOS release. I’ll let you go first, anyone know of anything at the moment?

I've been running it since dev preview 1, no Homebrew issues whatsoever over the past 2+ months.

Have a look and see if any of the packages you use regularly are on their 10.13 issues list: https://github.com/Homebrew/homebrew-core/issues/18493

Seems like I still don't have that button... ;(

IIRC it doesn’t support Fusion drives, so I can’t upgrade my Mac Mini yet.

You can, it just won’t convert the drive to APFS.

They're supported, they're just not upgraded to apfs. At the moment, only SSDs get upgraded automatically. Not entirely clear why, or whether that's a long-term plan.

Ah I stand corrected, cool

> Not entirely clear why

Might have something to do with the fact that APFS was designed explicitly with SSDs in mind.

So an early version of the beta set up Fusion drives with APFS, and then the next version switched them back to HDFS. I don't know the exact issue, but I would roll back like that if I saw there were data corruption/data loss issues.
