What is the removal assistant?
If you’ve owned, given away, or sold an iPhone, you’ve likely used its handy Erase All Content and Settings feature to reset it to its original state.
For years, Macs didn’t have this feature and it took a painstaking process to remove it. Traditionally, you’ve had to manually log out of all your accounts, wipe your startup drive, and reinstall macOS.
That was until macOS Monterey, where Apple finally released its own Erase All Content and Settings program for Mac, commonly known as Erase Assistant. It was introduced to simplify the process of resetting your Mac to factory settings and erasing all of its contents before reinstalling macOS on your Mac with just one click.
Who can use it?
Erase Assistant is a powerful feature only available on Macs with Apple Silicon (M-series chips) or Apple T2 Security Chip. Your Mac must also be running at least macOS Monterey or macOS Ventura or later.
If you’re not sure if your Mac has the Apple T2 Security Chip, the following are Mac models with the specified chip:
- iMac (with Retina 5K display, 2020)
- iMac Pro Mac Pro (2019)
- Mac Pro (rack, 2019)
- Mac Mini (2018)
- MacBook Air (Retina, 13-inch, 2018, 2019, 2020)
- MacBook Pro (13-inch, 2018, 2019, 2020)
- MacBook Pro (15-inch, 2018, 2019)
- MacBook Pro (16-inch 2019)
What does the Erase Assistant error mean?
The “Erase Assistant is not supported on this Mac”error appears if your Mac is an older model and does not have Apple Silicon or T2 security chips.
However, this error seems to be mostly experienced by those who own 2017 MacBook Pro models running macOS Ventura. But generally, older models can also have this problem.
There may also be rare cases where the error may appear on supported devices due to a bug.
What to do if Erase Assistant is not supported on your Mac?
There is not really a fix for the Erase Assistant Is Not Supported On This Mac errors, except that you are using a model that supports the feature and that you are running macOS Monterey or later on your Mac.
If you see a notification that you need to erase other volumes before you can erase all content and settings, you may have used Boot Camp to install Microsoft Windows on your Mac. In this case, you must first use Boot Camp to uninstall Windows and its partition before resetting your Mac.
If your device does not meet the requirements, you will not be able to use Erase Assistant. However, you can still use the traditional way to clean up your Mac, which is mentioned below.
