I hope they fix this quickly because I am having the same issue here!
Exactly the same on my MacBook Pro. Luckily you can do nearly everything on safe mode. Was a bit a hoffe and search to find where to upgrade my iPhone to 6
How were you able to get it into safe mode. My computer won’t even enter into safe mode
I got into safe mode as well. I would go to feedback assistant so you can send Apple your diagnostic information. That's what I did and hopefully that may help them in fixing this issue.
I guess I have the same problem. I can only boot in safe mode. And I cannot enter in my account. If I do, something crashes, my background pic is shown, then a black screen, then my pic again.. endlessly. And it looks as if there are no fonts, all menus are there, but without text.
Of course you can't downgrade and also you can't reinstall 10.15...
Is there somewhere a stand alone installer for 10.15?
Try reinstalling the software from the recovery mode (Cmd + R)
I just had the same issue after rebooting Catalina, the bar at approximately 90% for a long time, never reaching the login screen.
Rebooting was working perfectly since installed, but after about 6 hours using the system I rebooted it again and my system behavior was exactly like yours.
I dedicated about 2 hours investigating it and I found the cause and how to solve it.
The problem was caused by time machine "local snapshots".
Local snapshots are backups created on the local disk, even if you have an external disk connected and dedicated to time machine.
I have an external disk that always worked well, and it was working very well today on Catalina.
But Catalina creates various local snapshots also on the root disk (and there is no way to disable localsnapshots like on previous MacOS versions which was possible to disable just the localsnaps)
What technically happens when the progressbar stucks on 90% forever is that the system is somehow verifying those local snapshots, and it take hours, so we thing the system is frozen there just before the login screen appears. But it is not frozen, it is analysing data on disk.
This is bad, I agree, and is a Bug. But bugs are expected.. this is a developer version. Bugs are welcome somehow
How to solve it:
- Boot into safe mode [by holding Shift just after the boot bell sound],
- login to your user,
- open a Terminal window
Once on the terminal window prompt, lets check if this is the cause:
- type the command below to list all local snapshots
You should get a result like this:
Snapshot dates for all disks:
In my case I had 7 local snapshots as seen above, and we must delete them to fix Catalina (I decided to delete them all, because I have my backups already on my always connected external disk used by Time Machine)
The syntax to delete is:
tmutil deletelocalsnapshots <snapshot>
One by one:
tmutil deletelocalsnapshots 2019-06-04-082639
tmutil deletelocalsnapshots 2019-06-04-113651
tmutil deletelocalsnapshots 2019-06-04-135729
and so on....
After deleting them, run again the first command [to list the snaps] , just to be sure there will be no results.
Reboot the system.
Catalina will boot fast and you will be able to login and use it normally.
If you have any questions, feel free to ask.
Same issue here. I get as far as the boot logo/progress bar/spinning wheel but it eventually freezes. I was able to boot into safe mode, but it was unbelievably slow and eventually gets to the point where I can move the cursor but not click on anything.
I'm also able to SSH to it, so thankfully I will be able to install software upgrades once Apple hopefully fixes this issue.
EDIT: I tried to submit an official bug report, but I keep getting "There was an error trying to submit your feedback. Please try again later." so I guess not...
Okay, figured out the problem is one of my 3rd party kexts. I temporarily relocated the contents of /Library/Extensions and now my Macbook will boot just fine.
mkdir ~/Extensions-Backup && sudo mv /Library/Extensions/* ~/Extensions-Backup/
yep! That did the trick, even the user that wouldn't load in safe mode works now.
I was suspecting kexts, too, just didn't know where to look for them on this slow computer.
Thanks for the tip. In my instance, the culprit was AVVideoCard.kext. Removing that did the trick. I think that was left behind from an old install of 'Air Display'
I have this file too, and suspect it's the reason I'm having the same problem. Could you let me know how you are able to remove it? I can't seem to do anything in safe mode and I don't know how to remove the "read only" restriction in single user mode
UPDATE: wow, safe mode did work the 2nd time around. Deleting the file AVVideoCard.kext solved the problem for me too. Thank you for this post!!
This solution worked perfectly for me after a couple of hours of watching a black screen with apple logo. Many thanks!
for how many hours you watch the black screen with the apple logo?
Fixed my issue as well
this really help me after several different attempts , it boot up take a few minuets and then I can login normally
I try to use it but the same issue the mac shutdown after load 90% and am not able to enter to safe mode
Not working for me. Can't boot to Safe and Single mode, only Recovery.
Jack, did you solve your problem?
Yesterday I posted here a big writeup on how to solve it because I had the same situation as you, and the cause is different from the replies above. And also the solution is different.
It affetcs everyone who is using Time Machine, and the progress bar stops at 90% for hours.
But because I posted a BIG writeup full os details, its here for moderation and people cannot read it yet.
Are you sill having that issue?
Please send your write-up. Can't find it.
Umm, makes sense...
Yesterday reported (and sent a bug to Apple) that AppleKextExcludeList is missing on this first beta. I guess that's why you're seeing this message on boot, since the apple driver is unable to check the kexts against the list..., because it doesn't exist!!
Posted here yesterday https://forums.developer.apple.com/thread/117462
I had downloaded the beta 3 update and I was requested to restart my Mac (Macbook Pro 13 2017 no touch bar). After 10 minutes of installation I received a pop up saying that my disk is full and the installation cannot be completed. I was prompt to restart the device but the machine didn't restart.
After a couple of minutes I pressed the power button, the Apple logo with the progress bar appeard and went through until 40% and the black screen and the machine shuts down.
Is the software broken and I need to erase and restore the disk? That's a bummer although I knew and accepted the beta program....
Does anyone had this issue?
I am facing the same issue. I cannot boot into safe mode too.
I am also having the exact same issue, PLEASE HELP!
I was working on a file that I have to submit on Monday.
So I restarted the mac and then it was going to install BETA 2, so out of nothing it told me that there is no space in the disk, so I shut it down in order to boot like before and continue working on my file, but now around 50% completion of the bar the mac shuts down.
I cannot enter safe mode, only disk recovery, buy I need my file! how can I get my files back!?
Please HELP! I do not have too much time.
I am also having this issue. No matter what recovery mode I try, it's as if the MacBook can't find ANYTHING. I really don't want to delete everything since I'm a week or so out of backups.. yeah.. stupid mistake, I know.
I have the same problem and Apple support wasn’t able to help. Does anyone have a solution. Terminal say /var/root/extensions-backup: read only file system
I’m having this same issue. So far no fix and no help from the Apple tech support team
