You didn't look hard enough. ;D Please use the search function to check to see if there is already a thread on the same subject before posting a new thread. As you can see there is already a thread 4 pages long. I moved your post to the end of it. You can read thru this entire thread to learn about what was said about High Sierra.

I'm getting a bit shy about updates, but haven't heard of issues with High Sierra. ... are there concerns with the update? I'm not seeing issues posted here...

As with all major updates to the MacOS, a number of folks who upgrade via a simple upgrade install instead of a clean install have been reporting a nasty decrease in performance. I highly recommend a clean install.

Some folks with non-Apple SSD's have had problems with High Sierra and should wait until the manufacturer of their SSD offers a firmware update for High Sierra.

If you use any major disk utility/disk repair software (e.g. Disk Warrior, TechTool Pro, etc.) you should not use any of these products with High Sierra until you get an update specifically for High Sierra, or *very bad things* can happen.

As always with a major new version of the MacOS, I recommend waiting for the point-two update before considering upgrading.

I did a simple upgrade install and my MBP seems to be just a bit quicker in performance. Just wanted to have one other voice in that discussion. As usual, YMMV.

I also did an upgrade install on my late 2014 Mac mini with a non Apple Crucial SSD and didn’t experience an issue, except my self imposed issue.

Also upgraded in place on my iMac. I think performance has improved slightly. Mission Control animations are a lot smoother than they were before - Metal 2 is making a big difference. I did encounter two bugs though - a few days ago, the iMac crashed entirely (presumably caused by a kernel panic) after I tried booting up one of my VirtualBox VMs. Other than that, I have an accessibility option enabled in System Preferences that allows me to zoom in on any part of the screen - a few days ago after I zoomed in, I couldn't zoom back out - it just froze there. Had to force shut down. Other than these two incidents, it has otherwise been a stable upgrade.

Wow - thanks! Half the apps I use for teaching technology integration won't run in High Sierra. Greatly appreciate all this info!

We have found that folks who have problems with an in place upgrade were also very likely to have existing problems before they upgraded. Many folks erroneously believe that installing a new version of macOS is going to cure whatever that was ailing their machine. Sometimes a new version of macOS does cure things that were not right, but the majority of times it does not and in fact can make matters worse.

We do recommend that before upgrading you check to see if all your apps will be compatible and especially look for any notices from Apple about the upgrade. Personally, I have been doing in place upgrades on all my machines and have only run into one problem long ago. And that was when I upgraded from Leopard to Snow Leopard, I had to do a clean install because of kernel panics after the in place upgrade. I never did figure out what was causing it but the clean install of Snow Leopard worked. As the saying goes... your mileage may vary. ;D

I have to agree with this but man, can you actually recall those details that far back???

Anyway, if and when some small goofy things might happen, running the appropriate Mac OS X COMBO Update often sorted things out.

Hi.

Recently I installed High Sierra (Dutch) on my MacPro (dustbin). Now I cannot change my HD. Command I says: system:read and write, wheel: only read, everyone: only read. Trying to make these 2 read and write fails. Prompt says You do not have the permission! Unlocking the systempreference: where can I unlock this?
Also,MacOs itself is not quite stable. From time to time the Mac freezes, only to be restarted.

Maybe try reading some of the hits from here:

Randy - as w/ the comments from the others, I just upgraded my two laptops running Sierra to High Sierra w/o a problem - but I've postponed doing the same w/ my wife's iMac (early 2013 on Sierra) because of a fusion drive - I'm concerned about the presumed improved security of High Sierra for her computer - I know the HD will not be converted to APFS - SO, what to do? Any suggestions from those who may have gone to High Sierra w/ a non-SSD drive - thanks. Dave

I updated my wife's Mini with a spinner HD to HS just fine. The drive stays as HFS+ for spinners. I don't know what Randy will recommend, but for me, it was dead simple and worked well.

What parts of the "presumed improved security" are you concerned about??

Not good enough for her or too much with risks involved????

I quote myself from post #67 and stand by that. I've been doing in place upgrades now for 10 years and have only run into a problem one time and that was upgrading from Leopard to Snow Leopard. And that was mainly because Snow Leopard ended PPC. The recommendation to always do a clean install can lead to other problems and many times just winds up being more work and more headaches. Everyone has to follow his/her own way on that and decide. But let's not assume a clean install is a cure all because it isn't.

 

[MacInWin]

I'm with you, Charlie. Full installs aways seem to create problems for me, maybe because of product registrations, or lost history, or just plain just because. I've been doing in place upgrades with no problems and only did one full install when I was preparing an MBP for sale. I will say that a full install can help if the problem it is trying to fix came from mucking about with the operating system in the first place, but even then I would view it as last resort.

I've been doing in place upgrades now for 10 years …

I must agree and have been doing so for even longer, but did try a "clean OS X install" once or twice mainly to just see if there was any real difference, and didn't find any and have mentioned that fact here a number of times only to receive some flack.

Bottom line, just doing a standard install worked well when done on a good working system and saved a lot of time which otherwise can be a real PITA to get upgraded and updated.

Regardless, and just as the OS Installers advise before doing any OS Install — make sure you have a current good working backup!!!

Thanks Jake for the re-assurance - Charlie gave me the same advice a few weeks ago - and wife keeps complaining about seeing that HS upgrade message - just did CCC x2 on her iMac, so maybe time to just go to High Sierra! Dave

Just do a quick web search like this on:

Gotta keep the better half happy…

Thanks Patrick - know that I can stop these notifications but remind me that I should just do the upgrade, so will probably proceed - thanks for the links. Dave

Just a double reminder to make sure and check that all her apps she needs and printer/scanners etc. she uses work with the HS install FIRST!!!

And there is a current backup!!!

PS: I find that iMazing.app works very well and more complete than using iTunes. Unfortunately it's commercial software but affordable for all it can do. At least IMHO.
