Like, "high sierra release note", or "10.13 release note". Search terms you'd think would turn up something get blank results. What release notes? I looked most every logical place I could think of to find them, starting here on the developer site. I put up this post before noticing yours. I'm hoping that more people will report this both in feedback to Apple and in discussions. So, I don't understand why it's not possible now. It's very odd as I have already been able to test APFS on that same Firewire drive while running 10.12.4. Now, I'm thinking Apple have left something out of the installer or the documentation. I'm installing on an external Firewire drive which before your report, I thought was the problem. It also un-paired my Mighy Mouse but I guess that's just the usual beta glitch.
I also tried to upgrade via the Recovery partition and ended up losing the ability to boot from the 10.13 drive. There was no option to upgrade to APFS during the install. I've had much the same experience with my late 2009 27" iMac. How many years of life have people around the world lost because they couldn't access that little bit of info. Well, why can't Public Beta testers see the release notes ? I tried and got a permission error on my non-paid developer account. Or, we may not get that option at all and such older Macs will have to remain on HFS+ for High Sierra.Īdded after more research: It has been reported that the Public Beta 2 release notes warn: "Unsupported configurations in this seed release: HDD-only Macs cannot be converted to APFS."
So, a 2010 Mac Pro is supported for High Sierra, but not APFS? I presume such bottom of the supported list models are going to require a firmware update in order to boot APFS. No, I hadn't missed any check box to update the drive to APFS. The real test to myself then was upgraded Sierra to High Sierra again. Since High Sierra was now a completely dead partition, I had to boot to another drive with El Capitan on it, completely wipe my SSD and restore the Sierra and El Capitan versions back to the way they were. Like sixcolors, booting back the recovery mode and trying to select High Sierra as the startup disk (recovery being the only place the partition would even appear in a list), it was marked as unable to boot because it had not been blessed. Not that it was a great surprise to see El Capitan didn't know what APFS was. It would if I clicked the option to partition the drive it was on, but it would only show the High Sierra partition as unknown. Not even Disk Utility in El Capitan would show High Sierra in the list of available drives.
Just a bunch of messages noting each step, and a happy green check mark for Done!Īll seemed good except the High Sierra partition would not appear anywhere in El Capitan or older versions of the Mac OS I can boot to. Disk Utility made no mention of any errors. So to recovery mode I went and updated the High Sierra partition to APFS. Okay, I must have missed it, though I didn't remember seeing such a check box. The next thing I found was that for those users who were "in a hurry" and missed the check box, you could boot to recovery mode and update the drive/partition to APFS after the fact. The common answer that popped up was that you were supposed to check a box at the installer splash screen to do that as you installed High Sierra. Saw that it was still HFS+ and looked around to see why it wasn't APFS. I updated my Sierra partition to the High Sierra beta last week.
