So, let's wipe it clean and put a plain macOS file system on it (not APFS). More than likely, you've got APFS containers set up and if one of the volumes is corrupt and you're not properly removing it (via the format), this boot loop could be a symptom.

Given that you can get to 95% of the install, I'm going on the assumption that you don't have a firmware password nor FileVault enabled.įirst thing I would do is go a step further with the erasure of the disk. i have already a bootable USB for it, but i have to make more investigation. i think to avoid to delete my data, my next and only option is to downgrade to macOS Catalina. it doesn't show me any Volume !!! I when i check with Terminal i see a blank 1T volume. i was happy that i finally find a solution.

Today i tried Internet recovery by pressing cmd+opt+shift+R and for the first time it gave me 'OS X El Capitan' the OS that was purchased with my Imac from 2015 :/. but what i can see now is that my file system looks again like before the update and i can see my user again, and when i try to continue with the installation it tells me that my HDD is broken and i have to deleted!!. nothing, still give me Big Sur that i cannot install. new error: 'Installation cannot processed because the installer is damaged'. So i disabled the SIP (System Integrity Protection) and restarted the boot. i started the installation but at minute 13 an error showed up 'error occurred loading the update'.

I reached the recovery mode to install a new copy of macOS 11.4. Started my Imac with 'option' key pressed, choose my USB as startVolume and the boot went well. i made a bootable USB with macOS Big Sur 11.4 installer. My worst experience with a system update. else i will try a Catalina downgrade and go buy me PC. then i want to try the Target Disc Mode and therefore i have to buy a thunderbolt 3 cable and bring my imac to a friend's place that has Big Sur working. i saw that people did it without losing data. I have also two Volumes, a Macintosh HD (with 57 KB used) and Macintosh HD - Data (with 162 GB used).įor today i will make a bootable USB with macOS 11.4 and try to boot from external drive. If i'm not wrong, before it was in /Volumes/Macintosh HD/Users/MyUser/. Users/ is now in /system/Volume/Data/Users. My Macintosh HD still showing 169 GB but when i check the file system with terminal i see empty files. i can see it using Terminal in recovery mode. i reinstalled big sur on external drive with 1TB, ended also with error.īut since yesterday my file system changed. and i know it will end with the same error. It shows me at the beginning 2 hours and 19 minutes left than it goes up.

i did the Internet recovery many times (opt+cmd+r and shit+opt+cmd+r), but it ends with same error after hours (error applying the software update). Diagnostics gave error PPM002 but i can see my disks on the terminal and in Disk Utility.

Safe mode couldn't start, it an endless loop till release the Shift key. and this is what it means: 'A prohibitory symbol, which looks like a circle with a line or slash through it, means that your startup disk contains a Mac operating system, but it's not a version or build of macOS that your Mac can use.' !!

Since months i have an error while trying to download the update. According to Apple my mac should be ready for the new OS. I'm trying since one week to have a successful installation of macOS Big Sur 11.4 on my Imac late 2015 with Intel i5 processor and 1TB HDD. Image if i loose all my data !!! This will be my last Apple computer and will go back to Windows as they don't have this mountain of issues when they release a 'new SAFE OS update'. I don't have a TM backup because my external drive, 1TB, is permanently rejected by the mac i don#t know for what reason. To start i'm a music produce since 6 years and i bot my Imac 4 years ago and use it for my production.
