warning: crypto_val: object (oid 0x4): invalid state.key_revision (0)

Very little if anything should be lost. You might have a couple of passwords for websites missing, iCloud, etc, but all of your applications, files, desktop etc, should be just as there were before. After all, all of that information and settings were taken directly off of your Mac before the reinstall.

Yes, I believe that it is downloaded from Apple via the internet, so a slow connection will take longer.

Since it is a brand new iMac, you should also have free technical support from Apple available. Get them on the phone and they can walk you through the process too.

has anyone logged it with Apple - feels like there is something more serious happening thats causing ongoing issues.

FYI went to Apple store and ran first aid on their public test model, same error. I then ran the test in the regular iMac, no error. Seems to be a manufacturing defect.

Not sure if those are resolved as I had not have these issues before my reinstall. All I can say, my machine runs smoothly since I reinstalled and I hope it stays that way...

Spoke to Apple today and they said that they would really like to hear from all of us.

Please call them

Thank you for the tip @RollingRiverRock , but I did not have FV enabled.

I'll try the quit Finder restart if it happens today again.

Ended up reinstalling from Recovery mode, but without reformatting the entire disk so most of the migration settings are still in there-will see if it brings any relief this week...

Hi there RollingRiverRock,

How is it going with your new iMac Pro after erasing the hard drive and reinstalling the OS?

I am having the exact same issues on my new iMac Pro and wondering if I should wait a bit longer to return and replace... if it is just going to happen on the new iMac Pro also. Thinking I should wait a bit longer and see if Apple figures out what is going on and what hardware (hard drives / GPUs) ??? need to be replaced.

Also - when enabling or disabling FileVault ... does anyone get a progress indication ? on the iMac pro, at least on mine, it doesn't give a bar, or a percentage. It's immediate - I'm getting paranoid if its enabling it or not.

Also when enabled, does anyone get any lag/stuttering on the login screen when using BT keyboard/mouse ?

Can you recall, when you enabled file vault... did it take time ? was there a progress bar ?

The issue i have - which im not sure is normal - is that if i enable or disable file vault, its instant...no 'encrypting' or 'decrypting'

I just got an iMac Pro yesterday, base model. Same problem. Folders disappear. Mouse gets jumpy and keyboard gets "stuck". Having the same warning in Disk Utility. Not a good start. I really don't want to reinstall everything since I have to work with this machine. Is there a solution to this problem that doesn't require a clean install?

Thanks for your help.

I have the same issue but mine goes one step further...when that crypto warning shows up then everything just FREEZES and I have to restart my iMac Pro. NOT HAPPY and do NOT want to have to do a fresh reinstall of everything. I already did this TWICE in December with my order iMac and lost SO MUCH work time because of this 😟

Actually...I *really* hope that more of you will contact Apple Support and ask them about this. I thought about this further today and would like more input from other Apple Geniuses...but would prefer for it to be reported from others instead of myself so that they know SEVERAL users are experiencing this on their brand spanking new iMac Pros 🙂.

What concerned me was that the Apple Support Tech (a lady) whom I spoke with had NO IDEA what "Quick Look" was... she said to me that it was perhaps a third party application or some term that was quickly made up by users. She wouldn't quite believe me when I told her that it was an Apple feature and was specifically called "Quick Look".

The reason that I bring this up (Quick Look) is because it is the primary reason I used Disk Utility in the first place. I was getting some errors trying to quickly preview pdf documents in the Finder, using Quick Look (by pressing the space bar), and after doing some online research decided to run Disk Utility (first time I have run it on this Mac)...and that is how I came across the "Crypto" error. Thankfully after a restart I no longer have the preview error (altho' I have experienced it a couple of times in the last month).
ALSO, she did not know too much ABOUT the Quick Look feature at ALL. She also did not know that pressing the space bar brought up a preview.... she thought that it would just allow us to quickly change the file name (which is actually done by pressing the Return key).

She also told me that it is not necessary to go straight to Disk Utility every time we are having a problem and that Disk Utility will not fix applications. I think she was misunderstanding me when I mentioned Quick Look (that it was the primary reason I ended up using Disk Utility... because users who experienced similar problems recommended doing this after speaking with Apple tech support). I told her that I was concerned there was an issue with my HARD DRIVE and NOT an application. But still... she kept thinking that Quick Look was a third party application and that it was the primary reason I was calling in because I was trying to "fix it" when in fact I was calling in about the Disk Utility/Hard Drive error...

Hmmm....

Ok so, here are my problems, and ill try and be brief.

1) Warnings are never ok - it's a warning - and for apple to suggest 'its not a problem' is BS.

2) When i enable filevault or disable it, it's instant, no progress bar. This isnt the case on any other apple devices, even those using 10.13 & APFS. this COULD be a iMacPro thing - but it would be nice to know this. Why is this important ? is filevault even on ? it says its on, but if there is no encryption time for a HD with data on it - is it REALLY encrypted ?

3) When filevault is on ... the login screen is REALLY laggy ... stuttering mouse, missed keys - makes typing a password REALLY hard (the KB part is ok when wired, really bad when using BT).

4) then the whole 'missing files' thing in finder.. which is fixed via a finder restart/reboot - ive never had that on other apple devices with the same OS.

I wonder if they're related...i may be trying a SSD erase soon - becaus ei know this will eat away at me until i fix it.

My Quick Look issues have been mostly when wanting to preview iCloud Documents that were not downloaded to my computer.

I also use the Smart Sync option in my Dropbox- it also offers a "placeholder" for my files and allows me to download them if I need them rather than having 3TB of files on my 1TB SSD. ::grin:: These Dropbox files also don't work as expected with Quick Look.

One thing I've noticed about Apple Tech support is that I've been using the Mac system for longer than some of these people have been alive. 😮 I recently showed a Genius how to close all the Finder windows by option clicking the red button on a window. He was awesome nevertheless, and hopefully I'll soon have my broken MBP back and functioning. While sometimes frustrating, I do know they have the documents with the suggested workflows for troubleshooting and can get things replaced/repaired that I don't have authorization to accomplish by myself. ::grin:: And sometimes I hang up and call back to get someone else on the line when I know I need more than they can offer.

Warm regards.

I'll try to fix that on Tuesday. Here's my guess:

Due to the fact some are installing the OS new, but some are restoring macOS from TimeMachine, I think, it's an partion error. For sure Apple isn't installing macOS on each device they're delivering, I think they're using a master which is cloned to every iMac Pro. And this master is faulty...

It's a shame for Apple that during the last months they're only delivering crap. On macOS they just stopped to number every update to hide this a little bit.

Steven would be very frustrated knowing that. But it seems Tim Cook is looking on the shares only!

I'll keep you informed about my experiences...

Greetings from Germany!
