This is part 2 of my Upgrading M1 MacMini Storage which shows the reinstallation process of macOS to an external USB Enclosure and migration of your existing internal Storage, I also briefly talk about using Carbon Copy Cloner to clone your internal disk to an external USB connected one as well as deleting the internal drive.

Using Blackmagicdesign Disk Speed Test the M1 internal storage came in @ 2061 MB/s Write and 2121 MB/s Read and the ORICO with a Samsung Eco 970 Plus 2 TB came in @ 1000 MB/s Write and 2826 MB/s Read, Writes are a bit slower but still incredibly fast for day to day use.

Also if you do not want to do a freeh install you can clone your existing drive to your external with a tool like carbon copy cloner.

This is the second part in a two part series on how to upgrade your mac mini storage. If you haven’t seen part one, you can get to it up here. I’ll also put a link in the description as well. I highly recommend you start there, otherwise you’ll be jumping through halfway through the process. Let’s get started in the last video, we left off after creating our usb install source and putting together the orico usb enclosure. Let’s get these plugged in and start the install process. Once both your devices are plugged in, press and hold the power button on your mac mini until the startup option screen appears once the start up options appear, you’ll see your internal hard drive and our usb install source that we created in the first video. Let’s go ahead and install mac os monterey on our external drive we’ll walk through each step of the process. This first prompt is looking for you to authenticate your account from the internal storage so just click on it and hit next and then type in your account password. It’s the same one you use to log into your mac. Next the mac os monterrey installer will come up lets hit continue and agree on the license agreement. So we want to install mac os on this desk.

This is our external drive, but it doesn’t have the right format. So let’s go into disk utility to format this properly. You just got up to install mac os monterey and hit quit install mac os and we’ll quit and then go into disk utility. I like to go into view and show all devices and this will show us all of our devices. So this guy here is the mac os installer usb that we created. And then this is our orico external enclosure with the samsung two terabyte drive in it. So what we’ll have to do is click on erase, make sure this is set to apfs. I’m just going to label this orico and then click erase. This can take from 10 seconds to a minute once it’s done, click done and then we can exit disk utility and go back into install mac os monterey the same steps will continue and agree to the license agreement and then our external drive shows up. So we just select it and continue. We will select user click install type in our password and then we just have to wait. This process could take 20 minutes to an hour depending on the speed of your disk. I’m going to speed this up and we’ll resume when it’s done. Once this finishes up, the mac will restart into the setup wizard and then we’ll go through migrating our data ok, so now the mac has booted up off the external usb and we have the setup wizard up. Lets continue so select your country.

Connect to wi fi and then the migration assistant will ask you how do you want to transfer information and we’re going to pick this first option from a mac time machine back up our startup disk because our internal is a startup disk. And then this macintosh hd is our startup disk. This one here is our usb installer. And then this is a time machine disk on our network so we’ll select the macintosh hd and then enter your password because this volume was encrypted. So it’s going to run a couple checks and then it will ask you to select the information you’d like to transfer. For the most part, you can just hit continue if you were going from a bigger desk to a smaller desk, you’d have to drop some stuff to make your data fit into the new desk. This way we’re going to pick up 205 gigabytes and we’ll have 1.7 terabytes left available after transferring, and we’ll set a password for our new account and click continue. And then we just have to wait for it to finish again. Depending on your storage, it could take 10 minutes to an hour the migrations complete and we just click restart now and your mac will boot from the new external there is a couple steps it’s going to go through here to complete the migration and then you’ll be taken to the login page just log in with your password from your existing account and you’ll be good to go you’ll have to sign into your appleid and then we’ll set up your icloud account again. It walks through the steps really nicely. So this is asking to enter the password for the internal drive.

This is just asking because the drive’s encrypted and it’s trying to mount it so if we hit cancel and then we’ll go and disk utility. And while that’s loading, let’s check our storage. So this is our usb installer and we don’t need that anymore. This 251 gigabyte. Flash storage is our internal drive that i didn’t unlock. And then we’re running here off the orico with the two terabyte storage in it i will go through how to delete this apple partition after so and there we’re all set. We have migrated our information from the internal storage to the orico storage and have a ton more free space for half the price. So that’s the way to install mac os on the external drive and then migrate your data over i have had a couple of questions asking if you could just clone the drive using a program like carbon copy cloner. My initial attempt at this didn’t work, but with some further investigation, you can use carbon copy cloner’s legacy bootable copy assistant to make a bootable copy. You can also use this as a bootable backup for your system. It worked really well in my situation and took about 20 minutes to create you go into startup disk. Select your external drive. It just reboots and works as normal. You will get a prompt from carbon copy cloner saying that you’ve booted off your backup and it actually works really well. So we’ll go back into disk utility now. I’m just going to click on this apple ssd and click erase let’s just call it internal storage to erase or delete volumes and then to fully erase this mac, this will delete all media volumes let’s just go ahead and click on erase and then it’ll do a reboot. It shouldn’t delete your external will verify it here in a minute. That being said, i always have a backup copy of your data. I can’t stress that enough you should strive to have three copies, the original, a local backup and an offsite backup so that if anything were to happen, you always have it. Let’s see when it loads back up into connect to a wifi network and then if we just. Go to start disk. We should find our external and then just hit restart and continue so disk utility is loading back up and we’ll see how our volumes look. So we have our macintosh hd, which is all empty, and then our main systems here. I think that’s it for today.

Have an amazing day and i’ll see you on the next one. But with some further investigation, you can use carbon copy cloner’s legacy bootable volume assistant, copy assistant. But with some further investigation, you can use carbon copy. Cloner’s legacy bootable copy assistant. Yeah.
