OS 15.7.3 is crashing to black every few hours

OS 15.7.3 crashing to black every few hours. This just started with the most recent update. I have a 2021 iMac M1 with 8GB. I do not have any new software, everything I'm running has been on the system without problems for more than a year.


Anyone else running into this issue?


Thanks in advance.

iMac 24″, macOS 15.7

The report indicates that there are none of the usual suspected installed but you are extremely low on free space:


disk3s5 - Data [APFS Virtual drive]

Filesystem: APFS

Mount point: /System/Volumes/Data

FileVault Disabled

Used: 188.11 GB

Shared values

Size: 245.11 GB

Free: 20.96 GB !!!!!!!!!!!!!!

Available: 99.72 GB


You should bet an external drive (preferably an SSD formatted to APFS) and remove appropriately 80 GB of space. This is to facilitate optimal system and application performance.


Also you seem to be on a Managed laptop? Who owns the laptop? You have over 10 profiles. Normally on a single user machine there are none.


Also there are no indications of backups. The first thing you should do is get an eternal drive that is 1 - 2 TB in size for use with Time Machine which is included with every Mac.


If this Mac is owned by your employer take it to the IT Department and have them find out what's causing the problem.

Hi Mac Jim ID, Thank you, yeah, that's exactly what I'm doing. Got the "share report" copied to clipboard from Etrecheck, came here, open a reply, hit the "Additional Text" button, paste the report in there, hit Save, and then I get a blue loading wheelie and then the error message. I also took a screen shot of the error message and I can't attach it to this message, when I try to add an image it says "An error occurred while loading this image, please try again." Grrrr.

Is it bad form or against the rules to give a dropbox link? I could put the Etrecheck there and get a link for it.

Thank you.

Ok, you are doing it correctly. I have noticed that within the last hour there has been several reports where this site has not been experiencing problems with attachments and I suspect that is also the problem you are seeing. It has been reported to the moderators here and would expect it to be resolved shortly.


Please be patient and try again later. I just checked and the attachment problem is still appearing. Sorry for the trouble, but wanted to let you know that you are not doing anything wrong.

Thank you so much. I will free up more space and see if that continues to help. I have a couple of 1TB drives kicking around and will take your advice. I'm confused about the laptop thing. This is an iMac and I'm the only user.


There are a couple laptops that go in and out of the house with the kids, including one I bring home from the office sometimes that could well have multiple profiles on it, but I don't know how running a check on this machine would detect other devices not even in the house at the moment.


Any further thoughts you have on this would be welcome, and thank you so much.

Thank you, I probably carried over all the software from my old computer before this one, and I expect there are some dead softwares in there, I'll have to go through everything more carefully. About a year ago I changed my Dropbox account from paid to unpaid and removed most of what was in it, so there may be something going on with that. I'll follow your suggestion.


I seriously thought my hard drive was going to die when I had three kernel panics in a row, and truly appreciate the help from you and Old Toad.
