No entry sign on start up I’ve been running Catalina on a late 2012 iMac for some time. During the last update I was informed that the update could not be completed because of a kernel cache issue. On restarting the Mac I was presented with the no entry sign suggesting that the OS was not compatible. I opened in the Mac in Recovery mode, repaired the disk and tried again to reload the OS (automatically it tried to download Catalina). Again installation failed due to a kernel cache issue. I opened again in Recovery mode and this time erased the disk opted for a clean install. Catalina loaded ok with the latest update and all seemed well. However on trying to access some files on Lightroom I was presented with the wheel of doom and the Mac then crashed. It would not restart and I was presented again with the no entry screen. Clearly Catalina does work on this Mac configuration so does anyone have any idea as to what is going wrong?

Circle with a line through it on start up My iMac with 10.15.7 does not start up every time, since I upgraded to 10.15.7. About every other time I get a circle with a line through it. I have started in recovery mode and used Disk Doctor to repair and the messages said successful. With a Reset the computer boots just fine. I have reinstalled Catalina from Disk Utility. I have booted in the Safe Mood, then rebooted successfuly. I have also reset NVRAM Option, Command, P, R If I start up in Recovery Mode, and go right to the upper left corner of the screen, and do a restart, the computer boots just fine without doing anything in Disk Utility. What do I need to do to make my iMac more stable? Thanks Allan [Image Edited by Moderator to Remove Serial Number]

iMac will not boot after 10.15.5 update iMac (Retina 4k, 21.5", 2017) 3.6 GHz quad core i7, 16 GB ram Radeon Pro 560, 4 GB Mac OS Catalina 10.15.4 After an attempt to install 10.15.5, when attempting to start up on the internal drive, I see a zero with a slash thru it for about 10 seconds, then the Apple logo. The computer is stuck there and will not boot. System Preferences still shows the 10.15.5 update pending, but attempts to install it do not work and the Mac will not boot. Am using Carbon Copy Cloner to back up to an external drive which will boot if it is selected using the option key on startup. Attempts to restore the OS from the CCC backup do not work. Is there a way to clear out the 10.15.5 update files, and go back to using 10.15.4 and simply waiting for the next major OS release? Not having use of my internal drive and relying on my external backup is disturbing. Having that red flag on my system preferences that an update is pending makes me nervous as well. Ideas?
