Unable to install macOS Catalina 10.15.7 Update

Same here. Lack of disk space. Apple needs to fix their installer to report the lack of disk space during an upgrade.

And right after that they should throw out Siri and write a new version they can actually understand people speaking English.

I have a Macbook which is 2014 make. I have been getting this alert to update the OS but I have tried to restart and update it multiple times but nothing happens. I even tried one of the solutions mentioned by downloading the OS file from the apple site. That too did not work.

I HIGHLY recommend against installing this update. After installing it, my computer fans revved up to a thousand and my machine shut down. Now I cannot boot. I can get to the login screen and then the trackpad stops responding, the fan revs up to maximum and my machine shuts down. I've tried everything I can think of, including Safe Mode, but to no avail. I'm going to have to reinstall the OS, which is extremely irritating.

You maybe correct. My Retina MBA 2018 just experienced the run away accountsd issue. That is even thought I suggested restarting in Safe Mode which I did the day after the Automatic Update 10.15.7 was installed. I my case, Safe Mode did fix the issue for about 2 - 3 days but restarted with it using 150% to 200% of CPU.

Have just used Internet Recovery Mode ( Command + Option + R ) erased the SSD and downloaded Catalina again. Have not yet setup, so not sure if I received 10.15.6 or 10.15.7.

Interesting, did not experience any issues on Old iMac late 2012 with Rotational HD

Hey Micus1,

i just had the same problem. I also tried to download the dmg and install with that, but i have that the same issue as through the normal installation process in the System Preferences. It happens the same and my Air says i still have some updates to install.

Any other suggestions?

Thanks,

Ferenc

Hey Micus!

Really thanks for the fast reply... since then i tried every her written way, nothing helped for me unfortunately... my mac has needed a real brand new clear installation, i don't know why :D BUT I'm already finished with it so i have the 10.15.7 and almost ready for the settings also :D

Never mind...

Really big thanks for the help!

I had same problem, now solved.

I downloaded 10.15.7 from Apple and found I didn’t have enough HD memory to install it.

Cleared lots of rubbish from downloads folder freeing up 50GB.

Mac then happily installed it.

Seems auto update doesn’t tell you you need to free up space for update.

I had to run recovery mode because my screen was on the user login page with the progress bar not moving. Ran recovery mode, and updated macOS and gave me 10.15.7. Everything seems to be working fine now. But will be keeping an eye on it. Not something I wanted to have to do on a brand new iMac a week after unboxing it

Finally managed to downloads Catalina 10.15.7. If your device keeps asking to restart you need to create more free space on your HD. I removed a load of programmes that were taking space and the update downloaded no issues. It would be helpful if Apple could actually include a message telling you the reason rather than just not downloading

If you don't need to update then stay away from 10.15.7. Tried twice to install it via normal Apple Update and both times it failed. Initial restart on computer to get the upgrade going got me black page w/Apple logo, progress bar stops at about a 10th the distance and installation freezes. Power off, wait, power on and mac recovers. Tried doing the download and using the .dmg installer. Again, the same thing; installation freezes in short order. Except, this time after power off/power on and restarting, mac came back boogered. About this Mac showed 10.15.7 but apparently was not fully installed; don't know what happened. Very slow, lots of beach balls, color messed up and, worst of all, could not restore using Migration and Time Machine; Time Machine hard drive could not be found. Right now using restore function (command / R) and restoring from earlier Time Machine backup. This is a load of crap from Apple; B-team stuff for sure. This is *Exactly* why I left Windows. While Jobs may have been a real SOB to work for, he demanded perfection. The clown running Apple these days ought to take some lessons from Jobs legacy on being an SOB and start demanding perfection instead of releasing garbage like this ...as I type this on my smoothly running Surface Book 2.

The tip from Micus1 really helped!

I installed the update his way and now my mac doesn't say there's an update anymore.

It did ask for an extra patch and after that, it works like a treat again.

Thank you so so much for your advice!

Lots of love
