![]() This will ensure that you receive the latest security and system updates, and continue to enjoy the best protection from Sophos Home. ⚠️ If you are currently running macOS 10.15 Catalina, we recommend that you upgrade to the latest version of macOS. It is recommended to stay up-to-date on all operating system and security updates to keep your devices protected. While Apple continues to provide security updates for more recent versions of macOS, we expect Apple will stop providing them for macOS 10.15 after macOS 13 Ventura gets released in October 2022 The last security update from Apple for macOS 10.15 Catalina was in July 2022. Permanent retirement will take place in October 2023, at which point this OS will be moved to the bottom section and won't receive any kind of Support or updates. Sophos Home endpoints running this version of macOS will no longer receive new features, bug fixes, protection updates and customer support (including the ability to re-install the software- as the download is no longer available). Like I said, not 100% sure that is the cause but it is something to keep in mind.Sophos Home support for macOS 10.15 Catalina ends on October 31, 2022. I made sure to set that after I reset the SMC and NVRAM. The system seemed to just always default to my internal hard disk drive, but never explicitly had that set. The only hint of something I noticed before doing this-that might help someone-is I had a bootable USB backup of my main system disk attached during the last failed attempt to upgrade and-this is important-it didn’t seem like I had an explicitly selected startup disk set. I then ran Onyx and cleaned all caches-“System” and “User”-before launching the “Install macOS High Sierra” installer.Ĭrossed my fingers, let it do what it had to do and lo and behold… Everything went as expected!.I disconnected all USB peripherals-including a simple/small unpowered USB hub-except for a direct connection between keyboard and mouse and the system.I reset the System Management Controller (SMC).Sorry for the lack of specificity, but I finally was able to get macOS High Sierra (10.13) installed on my Mac mini (Late 2012 2.5 GHz Intel Core i5) with 16GB of memory and an internal disk that is a plain hard disk drive not an SSD. Why would this install fail this badly?įWIW, when I just rebooted into the macOS Sierra (10.12) external disk this is all I see on my main hard drive:įWIW, I have a MacBook Air (2013) running macOS 10.12 (Sierra) that is all SSD and has 4GB of RAM and you know what? Copied the installer over from my Mac Mini (2012), ran the installer, waited and everything is fine. ![]() My external disks are just basic external USB 3.0 drives. This is a stock Mac mini with upgraded RAM. Then the OS goes the multi language “Your machine has crashed, press space to restart.” Okay, I do that… And then it does the same thing again: Kernel panic-like messages over the standard Apple screen saying no OS found and then the “press space” message. I reboot and I get the black startup screen with the Apple logo, but then after a moment or so the typical command line messages that come up with a kernel panic pop up. I ran some errands and took a nap-this stuff takes time-and then when I check my system I see a message along the lines of “macOS cannot be installed on this system.” Strange. Once it downloaded, I double-clicked the installer and let it do what it usually does as I have done in the past while doing major OS updates. I downloaded macOS High Sierra (10.13) from the app store. Internal disk is a plain hard disk drive not an SSD. Subject says it all and here is what happened: I have Mac mini (Late 2012 2.5 GHz Intel Core i5) with 16GB of memory. So I am recovering from that and am not completely “panicked” about this… But this is baffling and annoying so sharing to help others if possible. Preface: I am now able to reboot from an external live backup I had of my previous macOS Sierra (10.12) install.
