Also having checked the start up disk, it also appears empty. I boot the Mac back into internet recovery and instead of the Mojave installer, I am greeted with the OS X Yosemite installer instead to which i attempt to install only to find out that the drive has randomly disappeared from the system installer. After a few attempts I attempt to restore it via Time Machine but there are no available backups. I restart the process, ensure the disk has been verified and repaired and still proceed to get the same message. Through the middle of updating, a message then pops up stating that there has been an error with removing the previous OS and that the instalation has failed informing me to restart the process. After that I then check the App Store again to find any updates and find that I am able to download Mojave to which I then proceed to do. Through a combinations of resetting the download finally completes and I am now at 10.11.2. I then proceeded to restart it a few times and reset the SMC and PRAM alongside. I run into a number of issues through the App Store where either the download would not complete or would not verify. I admit on the face of it this solution doesnt make sense (as you probably know, the SMC is mainly about power, thermal, sensor and lighting management), so if anything resetting NVRAM would make more sense. There are some printers that have drivers for Mojave, but my HP. There are no printer drivers that are compatible with Mojave and the drivers that worked with OS 10.13. Step 9: Let the installation finish, and once it is completed, reboot back into the installer drive (same as Step 5). After spending a good deal of time with Apple support I am restoring my Mac back to High Sierra. Select where you want to install macOS and click Continue. Being fed up with this I could see that there is a pending update through the App Store for OS x El Capitan 10.11.2 to which I then proceed to attempt to update. I encountered the same issue with 3 different brand printers used in my office. Installing Mac OS Mojave error Hey guys,I currently own an early 2015 Retina Macbook Pro and I am currently running into what is supposedly software issues.The issue started when my Mac was acting up with a few things Graphics processing (Pixelated). (I'm translating the French error messages).ġ- "The version of macOS present on the selected disk must be reinstalled" "Use Recuperation to reinstall macOS or select another boot disk" (There's NO version of macOS present on that disk and no other disk to reinstall the OS!!)Ģ- After selecting "Reinstallation": "This Mac must be erased before the installation can take place." (The disk was just freshly erased!!)ģ- Telling it to erase the disk: "Failure to erase this Mac" "This volume doesn't contain any recuperable user" (I could have told this in advance).Ĥ- I get a choice of returning to previous screen or to recuperation utilities.Īll in all, no way I can reinstall the OS on this erased internal disk. The installer (either the one of the Recovery environment or the one -13.4- on a bootable USB key) never accepted to install the OS. Reboot in Recovery environment, erased the two volumes of the system disk. macOS Ventura (13.4.1(c)), MacBookPro M2 Pro, 1TO internal disk.įollowing errors during system backup, I decided to reinstall the OS (my first and main mistake.).
