![]() ![]() I am currently attempting to install MacOS on Macintosh HD, curious as to whether it will be able to install this time.ĮDIT: I was able to resolve the problem, but it seems that I'm still not able to bypass the Remote Management. I had also attempted to run disk utility to see that I was unable to due to the fact that other volumes in the container were mounted. Select the disk format as APFS if you're running macOS 10.13 High Sierra and later. ![]() This was unsuccessful and gave the error message "no error" and then I restarted the system and tried again, this time successful. Select Macintosh HD in the sidebar of Disk Utility and click the Erase button in the toolbar. Of course, that assumes that TRIM has been correctly implemented. As well, simply mounting an SSD and deleting all the files with TRIM enabled will cause all the pages to be zeroed on any block that contained data. A static-free, fiber-free cloth works best, but most non-abrasive cloths will also work well. 'ATA Secure Erase' is a means of telling the drive to zero out all the blocks. Apply a little water to a soft microfiber cloth, making the cloth barely moist. But with the upgrade to Catalina, I now have 'Macintosh HD' and 'Macintosh HD. Normally, Id just boot into recovery mode, erase 'Macintosh HD', then reinstall the OS. I thought the problem might be that the drive was partitioned into 2 (actually 4 if you count the hidden partitions), so I attempted to remove the larger partition. Turn the computer off and unplug the power adapter. Hi I recently upgraded to Catalina (everything is running fine, no issues with the OS), but decided to do a clean wipe of the drive to start fresh. You'll know that the reset worked if you see the Apple logo appear and. After about 20 seconds, you can release your keys. I tried to reinstall MacOS and I forget the exact error message but it finished the download and was unable to boot up with it. Turn on your Mac and immediately press and hold Option, Command, P and R. After erasing them, I realized that normally Macintosh HD was the main volume. There is also a disk image, OS X Base System which I was unable to erase because it was in use. I erased Macintosh HD (which was allotted 17.72 GB) and a volume of another container on the same disk (which was allotted 482.34 GB). I booted it into Recovery mode and attempted to erase the drive. My old company gave me a MacBook Pro to use for work, and upon leaving they told me to keep it as they had switched to giving their employees PC's and had no use for it.
