erase

I took a PCIe SSD out of a late 2013 iMac I put in an OWC external case to use with my Mac mini M2, (its an Aura Pro X2 480GB), however I forgot to erase it before taking it out of the iMac, now it won’t mount, so I’m trying to erase but it’s stuck “deleting volume”, I don’t think it’s working...

Why is it that in the Yosemite version you can partition a drive without erasing it first while on newer releases, you have to first erase the drive then partition afterwards? It seems to me that the only good thing about Disk Utility post-Yosemite is you can immediately set a partition scheme...

I bought two of the SanDisk 4TB Extreme PRO Portable SSD drives (that are rated at up to 2000 MB/s) and tried to format them using Disk Utility in the latest MacBook Pro with the M1 Max chip running OS Monterey 12.0.1. They both would not format. I worked with Apple tech support and we...

I was erasing my Mac today to prepare it for selling, and during the process of erasing the drive I decided to reboot it in order to verify that the OS and the data was gone. I was expecting to get back into the same recovery mode. However, I was put into internet recovery which downloaded an...

I upgraded an external APFS boot volume from Mojave to Big Sur. There were two accounts and a lot of apps. On the first boot, they were all gone and replaced as if I had told the computer to pre-erase the volume, but of course, I did no such thing. Is it supposed to happen this way? What could...

Hello, I have a 2013 macbook pro 15" retina (running Catalina) with an internal SSD which last year failed in some way/messed up, after it froze, I powered it off and then upon restarting couldnt boot onto/select the Mac OS drive. Its worth noting the hard drive was partitioned so it had...

I bought a brand new Samsung T7 SSD, and I used macOS's Disk Utility to format (erase) it in APFS(Encrypted), scheme: GUID Partition Map. Before erasing (brand new), "Used" space was 108,5 MB. After first erasing as APFS(Encrypted, scheme: GUID Partition Map), "Used" space was just 20 kb. Then I...

I have a MacBook Air m1 that arrived with an uneven underside (second m1 with this issue this month) which makes it "wobble" on a flat surface. I am trying to erase and reinstall Mac OS before returning it but all trials fail. In the past with 11.1 my go to solution was to boot from a USB...

Over the years I've installed so much crapware on my computer that it just felt sluggish and contaminated to me, and I finally got up the nerve to do a clean install to start over again more 'minimalistically'. I've done clean installs many times in the past, but never on MacOS Catalina. After...

My iPhone was stolen Friday night - while it was unlocked and in use. Though I have a passcode, it should be noted. (Point 1: the thief could have kept it unlocked by tapping the screen) Within 20 minutes I was at a police station and a stranger let me call my device. It was now switched...

Hi folks, My girlfriend is working on selling her 2010 MBP. She had an issue where it would randomly restart, so we figured we'd try to format it and then go from there. I followed Apple's instructions here. In that process, the disk was unmounted, and, with it being an older MBP, there's not...

TLDR; Boot from install disk for High Sierra, Disk Util won't erase MacHD inside SSD container for clean install, Installer app says Mac HD is locked, never had FileVault engaged and it doesn't show core in diskutil list. I have tried to erase Mac HD but it never moves progress bar and I have...

Every time I erased my macmini, reinstalled and after restoring from my time capsule, the macmini will backup the total 360G again on time capsule. So now the macmini backup on time capsule already more than 700G and this time it is starting over backing up 360G. How to solve this? Thanks!

I just replaced my optical drive by a SSD on my MBP mid 2012. Whenever I start my mac it says that the new disc cannot be read and I'm asked whether I want to initialise or eject. No matter what I do, I cannot seem to erase the newly installed SSD. It says "Erase process has failed." I'll...

Hi guys, So basically I partitioned my harddrive to install Windows 10 via bootcamp but I ran into a problem. It did not install correctly. Now I can’t merge my partitions back together so I can start again. The normal way of doing this is by either deleting the bootcamp partition with...

For some reason, I have to erase and format all my flash-drives twice, because it fails the first time. It happens on all USB ports in back of Mac-Mini and with different Lexar and Verbatim USB flash-drives. Seems to always fail the first time, then completes the second time. They format on my...

I just bought an external hard drive (Silicon Power Shockproof 1T drive) as a backup drive. I want to partition half of it for Time Machine and half of it as storage. I started up Disk Utility and the partition button is grayed out. After looking through the forums, I realized I had to erase...

Hi everyone, My iMac recently had a graphics card failure and because of that I was unable to properly restore it with a new operating system. So, I connected it to my MacBook Pro via FireWire to fully erase the drive with target disk mode. This proved successful as the Mac boots to a file...

Hi - I am selling a 2012 MBP and have just erased the hard drive and restored it to factory settings. I was using El Capitan before I wiped it, but when I restored it to the factory settings, I think it re-installed Mountain Lion. The person buying it tried it out when El Capitan was...
