Where did you here that it won’t boot from HFS+? Just wondering...

Now that I think about it, that wouldn’t be necessarily a bad thing. It could possibly mean that only SSD booting moving forward. If that’s the case, there’s a chance that Apple will introduce a firmware update for native booting of NVMe SSDs for cMP. That’s a good thing as I see it.

Mojave could be a move, similar to FAT32 Windows booting moving to NTFS only. It was a good move.

As long as you can still r/w access to HFS+, I don’t really see an insurmountable problem. For those not wanting to change, the latest build of HS should be fine for years to come (at least 2).

Just my 2¢

Yes, it does. APFS on Fusion Drives and regular hard drives is not only fully supported by Mojave but even mandatory. Apple seems to have removed the switch from the installer that allowed us to install High Sierra on HFS+ manually from Mojave, meaning that every single boot device, whether it's an SSD, a Fusion Drive, or an HDD, is going to get converted to APFS whether you like it or not. And there is no way to avoid this forced conversion anymore.
 
To reiterate, High Sierra had been a disaster for me until 10.13.4, when it finally started to calm down. It's very alarming to me that it took 4 incremental updates to the OS before I finally started to see some stability, and really hope this isn't indicative of what's to come. Hopefully Mojave will be a much better experience since there seems to be no drastic changes to drive structure and display coding (I forgot the name of it) like there was with High Sierra, which I'm sure is what created so many issues. with that behind us and the new directive to focus on performance, I'm crossing my fingers that High Sierra will be just a bad memory by next year.

I've been through 4 or 5 OS upgrades, NEVER had issues like I did with High Sierra, just the occasional bugs here and there that were annoyances but hardly the show stopping "forced to reboot over and over" disaster High Sierra had been.

Well said. You're basically describing my experience, except I've had dozens of OS's since the 80s on various platforms and I have generally been pretty happy with most of them until Sierra. I don't like even Sierra that much, but at least it's stable. There's way too much lag in Safari and Finder amongst others.

Some are reporting a noticeably increase in speed in the very first beta of Mojave. Obviously, we can't be sure as to how consistent and stable it is yet, but I'm ready to upgrade the minute the public beta comes out and run it as my main OS. I did this with every OS since 10.7 until Sierra and it worked great except for the past couple of years. It will be a few steps farther along in development and after I try out all of my apps in a quick fresh install on its own partition, I'll upgrade my system to it. I want Darkkkk Moddddeeee! lol. And the alleged performance improvements. Can't wait. I'm jealous of the devs right now. How pathetic am I? :D

Your experiences hearten and unnerve me at the same time.

I'm sitting on 10.12.6 and very afraid to move to HS. This is my main work system and i cannot afford to have any issues. I boot from an external SSD in a non-Apple enclosure. Very nervous about possible issues.

What non-Apple enclosure are you speaking of.

CCC clone your drive to a different physical drive. Shutdown & disconnect your original drive. Boot from the clone and do an MAS (Mac App Store) update, this will avoid a firmware update you get with the full-installer, if you're afraid of that.

I doubt you'll have any issues, but if you don't like what you see, just shutdown and reinstall the original drive.
 
Dunno, when I am looking at so many complaints ever since High Sierra became available, I am thinking: I must be either extremely lucky, or people are overrating the minor issues.

Running the 10.13 since it came out in September, and I was only annoyed when it turned out someone can gain access to root without password. Although it didn't affect me, that was unacceptable bug.


Otherwise, 10.13 is running flawlessly, for me.

Hmmm, this might be an interesting way to try HS. I've never used the internal 1TB drive so I just left it unused in case i ever sold the machine in it's original state. Maybe I can just clone the SSD to that internal drive, boot off that and upgrade and see how it is. If I hate it I can just reconnect the SSD and boot 10.12.6

I shall ponder this. Thanks for the suggestion.

Easy Peasy, and exactly how I roll too (except that my boot drives are inside, all 4 of them).
 
I get a lot of spinning balls now that I did not have before..


I do as well, and am really unhappy to have to sit and wait....Also, my Mac no longer recognizes my Seagate back up disk and I must back up manually.
[doublepost=1531353120][/doublepost]My Mac no longer speaks to my Seagate back up drive - would love some suggestions on how to fix this. I CAN back up manually, but, who does that?!
 
Well, I'm sitting here downloading HS to upgrade my mid 2012 rMBP (16gb RAM, 256 ssd, i7, GT650), and I'm wondering if it's wise after reading through this and other threads. Sierra is still running quite well on my machine (which is not one that I rely on: my iMac is that machine). I made a bootable flash drive of Sierra and backed up in case, but I hope that I don't have to revert.

Probably neither choice.

Lots of different configurations out there running different apps.

Some people do have problems while some don't.
 
I had a terrible time with the beta. After being on my phone all afternoon with a really patient Apple technician and the supervisor who I was in contact with off and on, I now am back on my MBP, I am now on macOS High Sierra. Things are running faster. I'm almost nervous to shut down my MBP in fear that my problems will come back.

I'm sorry everyone. I just realized I posted on the wrong thread. I am so used to coming here. I didn't realize it until I saw this. I don't have that OS anymore. Moderators, if you would like you can delete this post and the most recent post I made here. I'm sorry. I didn't see my error. I was getting used to having my MBP back and functioning again. :rolleyes:

Several days later, and it's been running well on my machine.
