![]() I then erased the data on the flash drive and configured it to APFS so that it could be read by my Mac and I was able to install OS Maverick via the internet to that drive. However, the flash drive could not be read. I then went to my other Mac (2018 4 thunderbolt version) and copied the OS Catalina Installer onto a flash drive hoping that I would be prompted to install OS Catalina in the broken MacBook. I went back into disk utility to find no available hard drive ( other than the Mac OS base system drive). When I attempted to download Maverick, there was no hard drive/disk available to install the OS on. I then restarted in recovery mode and was prompted with the option to open disc utility or download a version of Mac OS Maverick via the internet. Upon restarting my computer, an image with a folder and a question-mark appeared. One was titled Macintosh HD and the other was Macintosh HD - DATA. I was clearing my early 2015 MacBook Pro 13" Retina, planning to sell it afterwards. Two GUID Partitions: Untitled (443GB) and MacOS-Clone (556GB)Įrased main HDD off device and now no hard drive can be found. If you want more tech details, some appear below. I'm thinking I will need to erase the entire machine and start with a fresh install of El Capitan (the last OS that worked properly).Īny thoughts are welcome. I have a Time Machine backup from the old MacOS but no drive to restore it to, unless I overwrite my MacOS-Clone. The "new" disk is named Apple SSD SM0128G Media, an Untitled 121.33 GB PCI Internal Physical Disk. Apple HDD has two partitions: MacOS-Clone and Untitled (formerly my MacOS/startup disk and hopefully my Big Sur partition). But the MacOS-Clone partition started up - not my previously designated startup disk.ĭisk Utility reports that I now have two drives in the machine: Apple HDD (disk1) and Apple SSD (disk0). I rebooted in Recovery mode and ran Disk Utility no errors. The drive rebooted several times before I saw the prohibitory symbol (circle w/ line through it). The Big Sur install on the MacOS partition failed at the dreaded "one minute remaining" mark. My 1TB SATA HDD is partitioned in half: MacOS and MacOS-Clone (I cloned my El Capitan install and data so I can run legacy software). 60 GB of free space on the target partition, but the install failed and Disk Utility now shows I have both an HDD and an SSD drive. Yet even if all of them were compatible now, I'd still wait until Sonoma "settles down", so to speak.OS Upgrade Failed Disk Utility Shows an SSD and won't boot I'm updating my Mac mini (Late 2014, 1TB HDD) from OS X El Capitan to Big Sur. Besides SD, they include 1Password, LibreOffice, Thunderbird, AppCleaner, and EasyFind. Secondly, besides SD, I use many third party applications exclusively (I do not use any that Apple provides), and I thus need to be sure that the critical ones I use are compatible with Sonoma. And for now, Ventura works well, along with Apple still actively supporting it. Additionally, there is nothing "earth shattering" I need in Sonoma. 3 version of the OS is released before moving to it. For example, a beta for OS 14.1 was released today. First of all, the first few versions typically contain bugs that eventually get repaired. In fact, for recent versions of the Mac OS, this is the earliest I have seen such a version of SD released.įor me though, I never move to the new version of the Mac OS right away. And I of course am very pleased that a version of SuperDuper! compatible with Sonoma has been released. He is always very responsive when I communicate with him. I always appreciate the SUPERIOR support Dave provides. Its simple-but-powerful Copy Script feature allows complete control of exactly what files get copied, ignored, even aliased ("soft linked" for the Unix inclined) from one drive to another. When you do, your current Documents, Music, Pictures - even iSync data - are available! You can get back to work immediately.Ĭlones for industry! SuperDuper has enough features to satisfy the advanced user, too. ![]() If anything goes wrong, just reboot to the original. With a few clicks, you can easily "checkpoint" your system, preserving your computer's critical applications and files while you run on a working, bootable copy. To ensure you can safely roll back a system after the unexpected occurs. In moments, you can completely duplicate your boot drive to another drive, partition, or image file.Ĭlones for safety. It can, of course, make a straight copy, or "clone" - useful when you want to move all your data from one machine to another, or do a simple backup. SuperDuper! is an advanced, yet easy to use disk copying program.
