![]() ![]() ![]() If this will work and is recommended, my neighbor says he has an older MacBook I can use. I've read that I can use another Mac PC to create a bootable OS X EL Capitan image and transfer it to an external drive, then boot it on my iMac to reinstall it. Though I have a feeling, the OS X Base is just a small recovery partition to assist with repairing and downloading the required OS. Isn't that what the OS X Base System is used for that I see listed under the the Disk Utility? If so, then I don't understand why I need to redownload the OS X EL Capitan 10.11 image. run DiskMaker X (version 6 for Yosemite through Sierra each subsequent release has its own dedicated app) to load the installer to the largest Untitled partition, remembering to select Another kind of disk so as not to wipe the entire drive. I resolved it by using Carbon Copy Cloner (they have a free trial) as no matter what I did I couldn't. I thought the iMAC provided a recovery partition that allows you to reinstall the OS from it. Each time I tried to boot from the image I would get the circle with line through it. Which now I know really just means I need to use the original Apple ID and p/w that was used with this PC back in 2016. But now I get the dreaded This item is temporarily unavailable. I'm pretty confident it's journaled as it's pretty old, and when I do attempt to erase it, it always defaults to journaled, though I know that may not mean anything.Īfter successfully erasing the FR CAP Source partition, now the main disk (ST3500414CS) is an option when I select to reinstall. I have provided pictures with details from Disk Utility if that helps. ![]() Does that mean it repaired the issues successfully with the partition map or just that it completed the scan operation successfully?Īnyhow, I rebooted, and it seem to be booting up with the progress bar moving slowly under the Apple, then suddenly the OS X Utilities window popped up. I just finished running First Aid, and it said "Problems were found with the partition map which might prevent booting." then said Operation Successful. If the 500 GB ST3500414CS drive is available in Disk Utility, why can't I select it to reinstall to it? DiskMaker X is described as (formerly Lion DiskMaker) is an application built with AppleScript that you can use with many versions of OS X/macOS to build a bootable drive from OS X/macOS installer program (the one you download from the App Store) and is a bootable usb creator in the os & utilities category. I'm curious why it's labeled as ST3500414CS Media rather than Macintosh HD, but I'm more concerned now why I can't erase it? And also why if I select to just reinstall the OS (not erase the disk) that my only option is to use the Recovery HD, which only has 120 MB available of 650 MB total. I'm trying to erase and reinstall OS X EL Capitan 10.11 but every time I attempt to erase the first/main internal disk, it always fails. ![]()
