Time Machine (Encrypted) Not Auto-Mounting on Boot with 10.14.4

Thanks to apple inc. for listening to it's customers with 10.14.5 , not only over the disks not auto-mounting problem , but also with the new(old) iOS device support in iTunes .....well done apple inc.

[was not spam , "vaporland", but , a one-off offer for apple customers on this page , made AFTER the problem at hand was solved : in recognition of their help in getting apple to fix this disk's not mounting problem , nothing more...]

This (https://discussions.apple.com/thread/250260889?answerId=250583127022#250583127022) resolved the issue for me. Thanks!!

Yes, I'm experiencing the exact same issue with a secondary encrypted drive (Software RAID on two SSD) on my MacPro 2012. I have to manually mount it via Disk Utility after each boot.

You are not the only one. It started with 10.14.4.

I tried. Unfortunately, a script requires manual or automatic input (cleartext...?) of the passphrase to decrypt the CoreStorage and then mount the drive. Somehow, Disk Utility doesn't ask for the passphrase to mount the disk if it's the same as your login password.

Same thing here. I have tried many things. Today, I even reformatted my TM ssd disk, but without solving the issue. TM ssd is not auto mounted. I think it is a bug.

Best,

A.

Glad to see I'm not the only one having this problem. Been trying to fix it all day with no solution. I have 2 external encrypted hard drives and they won't auto mount on boot. I have to go into Disk Utility and manually mount them. I thought maybe my drives were failing but no it's the update since this only started happening right after I updated to 10.14.4

So this means the issue is specific to encrypted Time Machine drives. Thanks for the clarification. I filed a bug report at https://developer.apple.com/bug-reporting/ four days ago and it was flagged as duplicate within a few years. So it seems Apple is aware of the issue.

To be more specific: I use one my iMac 27" Late 2012:

• USB-C-Drive, connected to an USB 3 Port an my iMac
• Thunderbolt 2-Drive, connected to an Thunderbolt 1-Port an my iMac

Both Drives show the exactly same, strange behavior.

I have a similar problem when trying to do a time machine backup to an Apple Timebox. As far as I know neither my main hard disk nor the Apple Time Box are encrypted disks, though there may be a couple of encrypted folders on the main disk and in some form on the backup.

It claims that there is either some encryption or de-encryption in operation and to please wait. Eventually, anything form 20 mins to a few hours later it allows a backup to occur.

Not sure if this is related to changes in Mojave 10.14.4 but I never saw this problem before that!

10.14.4 caused both my time machine & Data Disk to be returned unmounted after restart. Apple engineering informs that if your machine is modified in any way , then , YOU WILL NOT RECEIVE APPLE SUPPORT UNTILL YOU RESET TO FACTORY SETTINGS .

I WAS TRICKED INTO BUYING A MODIFIED MACHINE , WITHOUT MY KNOWLEDGE , AND NOW I HAVE BEEN CAST ADRIFT BY APPLE SUPPORT , WHO ARE TRYING TO PRETEND THAT I DID THE MODIFICATIONS , WHEN , CLEARLY , I DID NOT .

CONCLUSION : if you modify your machine in any way you ( or buy a modified machine , second hand , even without first knowing that it has been modified ) you will now be treated as a "jail breaker " and criminal , and turned away from apple support , until you fall into line and factory reset your machine so that your little box made out of ticky - tacky is exactly the same as everybody else's little box made out of ticky -tacky !.....

N.B. now that Apple & Qualcom have (sort of) settled their dispute , maybe , just maybe , future mac os updates will , once more be a source of joy & pleasure , instead of the time-wasting nightmares that we have come to know since 10.13.6

Yes thanks iT-F, I had already attached a whole page of this forum in an email to apple support staff- but will give further feedback ......it seems to me , however , that these forums are the place that apple staff push people who they can no longer help / or are not allowed to help : the latter being people with "modified" machines , who will be told by apple that they are no longer supported . ....CURIOUSLY , a day after the above email , the (modified) data and time machine disks started mounting ALMOST automatically( ie automatically , but with some slight delay in comparison to the mac HD) , but now the time machine is presented as yellow , meaning I now have to select the disk in system preferences & back up now in the drop down menu to colour it green ( ie to do everything automatically , as it should , at least before 10.14.4.) .

After updating to 10.14.5 last night, my 8TB WD Time Machine drive won't mount. Can't repair, erase, etc.

Never had the issue prior, but it either it is a terrible coincidence or the issue isn't fixed.

Any help would be greatly appreciated.

Hi everyone

I am absolutely desperate for help but have very limited technical knowledge!

My iMac suddenly started unmounting my three external hard drives. I am a photographer and have all my livelihood on these things.

I contacted apple and they said they can't imagine what the problem is but I will have to reformat my discs.

I have had a similar problem occur on my MacBook Pro with one of my hard drives - the Sandisk extreme SSD.

But after the problem occurred first, I had a futile conversation with apple and then I noticed that they suddenly mounted and so I ran a disk utility first aid on the two that came up.

I have recently bought these hard drives and used two of them before my iMac was wiped, because it has never worked properly, and one of them, since it was wiped.

The newly set up iMac was updated to Mojave 10.14.5 and the MacBook Pro is on the same system.

Apple have now told me to start my iMac up in safe mode and when the hard drives show up, run first aid and then move all the information across to one, reformat each in turn, and then put the stuff all back on.

However, after starting the iMac up in safe mode, predictably, neither hard drive will show up.

If I go into disk utility, they are pale and show as unmounted. When I ask to mount them, I get no response.

I did try and run first aid on one of them and it did allow it to happen but left it unmounted.

I am an extremely stressed lady now and just don't know how to move forward :(

Same here, used to auto-mount fine before the update. I have my password saved in the keychain so when I mount it manually from the disk utility, it doesn't prompt me for a password.
