You will want to decide how much drive space you want for each system. Once the drive is erased (and you have reverted back to a Mac OS Extended format), then you will be able to install Sierra - followed up with reinstalling Monterey. If you still need to erase the internal drive (and you do need to erase that drive to do what you want with a Sierra system!), then you have to erase the drive with a system newer than Sierra. Someone found the solution to my problem, so I'm posting here in case it might help someone:īoot to a High Sierra installer, and the internal drive will be now visible, and you can erase, or do anything else that you need to do with the internal drive. I just want to get rid of Monterey and get my old Sierra back. I posted to and received only copy-pasted suggestions that I've already tried.)Ĭlearly there is something fundamentally incompatible between the APFS file system and HFS that's preventing cross-pollination. (I've been using Macs since 1986 and am very comfortable trouble-shooting. I have read a dozen articles that seem somewhat related, but haven't found one that directly addresses my issue including and and Īnd only turned to this forum in desperation.I wanted to do this but when I go to Disk Utility on the old laptop and choose "New Image" - the "Macintosh HD" option is grayed-out. The one thing I can think of that I have NOT yet tried is to create a new recovery flash drive apart from the Time Machine backup/boot and the dedicated boot drives that I have. Or when I choose "Restore" to the new partition, I get the error, "Source volume format on device is not valid for restoring" EG, "Error 13" which appears to be some kind of Unix code. This generates error messages that appear to be some kind of incompatibility between Sierra and Monterey. I have tried within Monterey, partitioning the new SSD, creating a HFS partition in order to install Sierra on that. In all of the above, have tried "Restore", "Install New OS", and "Disk Utility" in these attempts, the SSD drive doesn't appear as an option. I've tried everything, including creating a HFS partition on the SSD, but when I try to run disk utility from the external drive, it doesn't even see the SSD.īooted from Sierra Time Machine backup external drive.īooted from a dedicated external Sierra boot drive. I have a Time Machine / bootable external HD but can't work out how to erase the new SSD and put Sierra on it. Obviously, don't click on any suspicious links in the reviews, and have a nice day/night.I bought a refurbished 2015 MacBook so that I could continue using my legacy software, but its SSD came preinstalled with OS 10.14 Monterey. I notice a handful of people that come here spamming viruses and porn ads, and I feel like I'm partially responsible for reviews like that. It is version 12.6.06, and 12.6.03 was used to circumvent an error preventing me from creating the file. I changed it to 12.6.03 so when you boot up this ISO, and quicklook at the app inside you may see that it says 12.6.03. I had to modify ist () to change the app version in order for it to work. dmg file also installs the application to your Applications folder.į2 - The app used to make the ISO was downloaded prior to Sierra being invalidated from the App Store, and also prior to being added to the support article in PKG form.į3 - When using the app to build the ISO, it failed. (Keep in mind that opening and running the. app/Contents/SharedSupport (This generates the app, and I will explain how the app is used) Move InstallESD.dmg to Payload/Install macOS. pkg file was unziped using pkgutil -expand-fullĢ.
