It runs horrendously bad on my MacBook Pro. Trying to convert to APFS failed and can no longer access the external HDD (it failed I my internal HDD too). Will reformat and just leave Sierra on it. Can’t understand why it’s so bad on older non-SSD machines. Sierra runs really well. I had hoped that Beta 2 would fix this issue, but no.
I don't see anything weird, could be because you're booted into it. Maybe try from the recovery partition. The virtual/physical is mostly likely because you have FileVault on or the disk is an encrypted journaled system. All encrypted volumes/partitions have a "CoreStorage" partition that is virtualized when unencrypted by the system.
I've just noticed all my encrypted drives have an accompanying virtual volume and haven't seen it elsewhere. You could also just use time machine and restore from time machine after resetting the internal drive, should be no data/preference loss. I also like to occasionally do a fresh install though and just copy preference files of apps I care about from /Library/Preferences/ though that option definitely more troublesome.
This is all that I have on this laptop, but it's also a hackintosh. Though the same is also true for external unecrypted/encrypted drives on my real Mac at home.
Seems weird if you've never encrypted or used filevault, but I don't know if there are uses for CoreStorage volumes outside of that. Ex: pretty sure all APFS volumes show up as CoreStorage + virtual but I'll have to check my unencrptyed disks later.
Exactly. That’s what I am thinking.
I just got a chance to look at mine, and the only real difference is that the recovery partition is in the synthesized volume and I have a reboot partition. The "two shared" is because apfs disks share all available disk space. If you had an external apfs with two partitions, they would both share the entire space of the apfs and consume the space as the partitions need. That's why the Macintosh SSD shows up as 115.3 GB partition, because that's the space it's used of all apfs space. At least this is my understanding of how APFS is supposed to work. Mine is shared by 4, because I have a preboot, and recovery apfs. Apparently the VM is essentially a swap space partition.
Yes, you CAN! As with any OS upgrade, the best thing to always do is a clean install. Yeah, takes a bit longer, but it eliminates so many problems that can occur. At this time, Apple's 10.13 installer does not ask if you want your HDD partition reformatted. But you can do this yourself either via Disk Utility v.17 in High Sierra installed somewhere else, or follow these instructions [ https://www.howtogeek.com/272741/how-to-format-a-drive-with-the-apfs-file-system-on-macos-sierra/ ], or use a third-party utility - I remember reading the product description of one, but cannot remember its name, sorry. After you have re-formatted the spinning hard-disk drive VOLUME, run the High Sierra installer. I strongly recommend you do this from a saved download of the installer on a separate partition/drive, while booted up in Safe Mode from El Capitan or Sierra
My post was from June, when it wasn’t an option. I did try to force a conversion on my old HDD (before I got my SSD) and it didn’t go well and I couldn’t access the drive.
