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. Other OS will operate differently.Preface: I am now able to reboot from an external live backup I had of my previous macOS Sierra (10.12) install. This is only a potential solution for GP connection issues on MacOS. Click "Allow" and that should give the necessary permissions for Global Protect. The approval request should show 'Palo Alto Networks' as the developer. Until approval, future load attempts will cause the approval UI to reappear but will not trigger another alert. This approval will only be present for 30 minutes after the alert. This directs the user to approve the KEXT in System Preferences > Security & Privacy: When a request is made to load a KEXT that has not been approved, the load request is denied and macOS presents the alert below: To resolve this, the KEXT needs to be approved. This in turn prevents the Agent from connecting to the service. The KEXT associated with Global Protect has not been approved and so cannot be run. NOTE: Approval is automatically granted to third-party KEXTs that were already installed before transitioning to macOS High Sierra. When a request is made to load a KEXT that has not been approved, the load request is denied. MacOS High Sierra 10.13 introduced a new feature that requires user approval before loading newly-installed third-party kernel extensions or KEXTs, for short. This indicates that the Global Protect Agent cannot reach the Global Protect Service running on the client. After looking into the PanGPA.log and finding the following: It shows as constantly in the 'Connecting' state with no changes in status. Global Protect Agents installed on a MacOS is having repeated issues with connecting to the Global Protect Gateway.
