    Does this work without a Developers Account? I know the download does, but what about the install? Thank you either way. :)

    I upgraded. First thing I noticed was that Discord and Slack needs to update their code to re-hide the title bar.

    Secondly, I spent about half an hour converting a HFS+ Case-Sensitive drive to APFS. The reason why it took so long was the fact that I couldn't convert it while the OS was running, so I had to figure out how to reboot into recovery mode (I rarely need it :D), got it converted with no problem, then updated /etc/fstab changing hfs to apfs and we were good to go.

    Thirdly, holy hell they were not kidding when they said folder sizes would be instant. My aforementioned mounted partition has about eleventy bajillion small PHP files, and the entire folder was sized pretty much as soon as I ticked the button. Seriously impressive work.

    I also launched all of my commonly used apps, and they all started up without issue. Haven't actually used them yet, but they all seem to work fine.

    Overall, I'm plzd with this upgrade :)

    I'm installing it now. Does it update the filesystem during the install?

    I like to know if do change the format by itself from HFS to APFS or we have to format the whole thing in the recovery and clean install it?

    It works if you use this in a Terminal window, before you open the link in the Mac App Store:
    Code:
    sudo /usr/libexec/PlistBuddy -c "clear dict"  -c "add :SeedProgram string DeveloperSeed" "$3/Users/Shared/.SeedEnrollment.plist"

    AND


    Code:
    sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate CatalogURL "https://swscan.apple.com/content/catalogs/others/index-10.13seed-1.sucatalog"
    You can undo the last command via:
    Code:
    sudo softwareupdate --clear-catalog
    This assumes that you are already logged in your MAS account within the MAS! Works only on OS X (macOS) 10.11.x or newer!


    :D

    Are you able to run both Sierra and High Sierra on the same Mac?

    I don't see why not, simply create another partition as always.

    I don't have an SSD so guess APFS won't be offered.

    So that’s mean for iMac that I have which is 1TB SATA, the APFS won’t be available? or if won’t make any difference?

    No and that demo of video files copying wouldn't be possible on a drive with moving parts.

    But I think you can convert to APFS from HFS on any drive but you won’t get those goodies.

    I'm not sure that is true. Can someone confirm?

    Yes, I'm running both in separate partitions on my rMBP. High Sierra is running on an APFS volume, and Sierra on Mac OS Extended (Journaled, Encrypted) volume.

    Yeah I'd love to know how a spinning drive can duplicate gigabytes of data instantly without running into seek time, latency and bandwidth issues ;)

    APFS uses data deduplication, which means it does not copy files. Instead it creates two file IDs for the same data. Those file IDs are 8 bytes (64 Bit) long and usually embedded in larger meta data blocks like 4096 byte (4 KByte) blocks. The 4 KByte blocks are smaller than let us say a 8 GB video file (≈ 8.589.934 KByte). That is the reason why APFS is so much faster in certain scenarios than HFS+. If you edit files from APFS volumes and save them, APFS is not faster than HFS+.

    That clears it up. I had a suspicion it wasn't true duplication and that when actual duplication is needed there won't be such a speed advantage, especially with large files that oversaturate available bandwidth.

    Does the upgrade convert the filesystem automatically? Do I have to do anything?
