How to Boot your M1 or M2 Mac from an External SSD

[@JustLearning]

Thank you so much for this video. I had purchased a Mac Mini 2020 with 8GB RAM and 256GB of storage. With your video I was able to use a 1TB SSD as my Start up drive. And even use the migration tool and got my old settings and stuff added to the new SSD drive. Thanks again.

[@lucannon]

Hi Antonio, how did you manage to transfer your old files to the new startup ssd by using the migration assistent?

[@castillo4141]

@@lucannon I'm guessing he had a Time Machine backup in another external drive, so he just used the backup with the Migration Assistant, at least that's what I would've done.

[@MaglorMusic]

how much slower is the performance when working from external SSD? Would you say it's noticeable?

[@MikeHightower1]

Best part of buying the mini or iMac, you can just focus on ram specs rather than hard drives! Is been years since I’ve done this. But I’m about to do it again

[@gangjira]

Super useful for evading employee monitoring software installed on your work laptop without having to open it up!

[@EliFleming]

Except they can disable booting from external drives. 😟

[@wesulrich3783]

Literally kept me from buying a new computer. My 2017 iMac now runs better than it did when I first unboxed it thanks to your tutorial. Many thanks.

[@MaglorMusic]

[@wesulrich3783]

The external SSD is faster than my Mac was out of the box. To be fair, my computer use is limited to internet activity and Office suite software mainly.@@MaglorMusic

[@malcolm4k270]

@@MaglorMusic think it would be faster. Just got the 2017 MacBook Pro no Touch Bar and it’s has a HD instead of ssd so using an external ssd would probably be faster idk.

[@stevey500]

In the boot selection screen, you can also hold control or option to set the drive to always boot from. :) You can also hold shift to invoke safe mode boot for the desired OS to boot from.

[@Distortionghosts]

Hi! I'm new to Mac, once I finished installing, & got to the restart countdown, it booted back to internal ssd instead of finishing installation after reboot. Do you know what is being done wrong? I followed every step exact until this point

[@PalashGupta]

Same problem with me

[@INBRO-VIDEO]

This video saved me! 3 weeks ago I bought a base M2 Mac mini and immediately tried to instal Ventura on my Samsung T5 SSD. After the installation I was unable to boot from the external. I tried once more reinstalling the OS but to no avail and gave up on the idea, assuming there was something with the Mac design making it impossible. Fast forward to yesterday when I came across this video and was idly watching it when my error became apparent . . . I was not installing the OS on the physical drive! Within 30 minutes of seeing those first few seconds of your video I was up and running with a Mac mini booted from the external Samsung. THANKS!

[@Marco-xz7rf]

hh, someone needs to design a nice case, that can clamp under the macbook and hook up elegant via usb c without adding to much thickness and width. Than you can insert loads of stuff, like sd card, normal usb, maybe even a custom magsafe, 2,5" ssds, nvme pci-e ssds, a coolingfan for the air, more energy storage. Whatever you need. This could get handy, if the internal ssd might die and you don't need to open up your mac, okay maybe you need to remove the bottom cover to screw in the new one but exept that :D

[@efmoura1212]

This is the standard by which all help videos should follow

[@omidsn2636]

Can it help to resolve the SSD swap issue? Have you checked out whether the SSD swapping happens between the Internal SSD or the external one while booting from the external SSD?

[@BartechTV]

It completely eliminates disk swapping to the internal SSD. It's the drive you boot from that macOS swaps to, so any swapping goes to the external SSD. You can unmount the internal ssd in disk utility after booting if you want to be extra sure.

[@jonathanloaiza]

Hello there, I love your videos, thank you for sharing all your knowledge. I wanted to know if I can do this with a Hackintosh. So I can run Mac OS from my external SSD.

[@BartechTV]

Yes you can do the same with a hackintosh, it works just the same.

[@thebozzIDW]

I tried following these steps and for someone reason after installing it on the external device (in my case a regular USB and USB-C flash memory stick), it never boots up into the second stage of the installer. I am able to view the USB flash stick from the boot menu but clicking Continue does nothing. Does the external device need to specifically be a SSD?

[@PalashGupta]

M not getting like fresh mac setting option after restarting mac couple of times , its only came to original mac os the old one

[@Madmohawkfilms]

Hmmm just tried this with T7 drive, installed and tried to boot from it and won’t boot. Im perplexed, followed video. Going to try it again. Hmmmm sertting owner and copying details from internal drive unchecked this time, that might have been what threw things off.

[@nick8945]

I followed your instructions exactly. But no matter how many times I erase the hard drive in dial utility, (the hard drive itself and not just the volume) my Mac begins the install but never completes it. So I am left with an incomplete install on my SSD everytime. I've formatted my external SSD "APFS" Scheme is "GUID Partition Map" Are the any reasons as to why the installation of the Mac OS keeps failing?

[@DanaGarrison]

Have you tried using the software called super Duper, and creating a full clone of your current MacBook onto an external hard drive? Defending on which OSU are on, this can be a bootable hard drive that you can work from

[@Mr.DarkShark]

Did you notice any performance drop because of the booting from external T7 ssd? (in apps like lightroom, photoshop, premiere, etc.)

Very good instructions. Does the internal drive have to be the same version of Big Sur as the external drive?

In the process I lost my boot up chime until I upgraded the internal drive. Thanks very much

[@jaredjohnson5976]

For MacBook Air M1 running Sonoma, make sure to plug your external drive into the second USB-C port. The first port’s configuration might prevent you from booting from the external drive.

[@matheokoning4456]

Is the installation only for the MacBook you installed it with or can you use the external hard drive on other MacBooks as well? I have an installation of Sonoma that I used on my 2020 intel but I can't get it to work on my M1

[@efmoura1212]

Got a new mac studio with 500 GB hard drive. Crashing a lot because of GB intensive apps and having lots of apps open at the same time, which is needed. Would it resolve my crashing problem if I were to run only the OS from the internal drive and everything else from an external? And if so, can you tell me how designate the external drive as the default for everything else?

[@BartechTV]

Hi, when you say crashing, do you mean literally spontaneous kernel panics and shutdowns, or are you seeing a message saying "Your Mac has run out of application memory"? A Mac should never crash just because of memory intensive apps. You can expect a warning message as your internal SSD reaches capacity, and you'll see a message if your Mac runs out of RAM which will ask you to close apps, but it should never just crash. Random shutdowns or crashes sound more like a hardware issue. I sincerely doubt that moving your data to an external drive would have any effect in reducing or eliminating crashes. As a general rule, you should aim to keep about 20% of your internal drive free (so, in your case that would be 100GB) as it helps with wear leveling. As for forcing your Mac to use external storage for everything except the OS, there isn't a system-wide setting for that. It's up to each individual application. For example, in Final Cut Pro, you go to Libraries, Properties, then Storage Locations, and choose where you want render files and caches to be stored. In Lightroom, you store your library on the external drive and set the cache location to the external drive under the performance tab in preferences. If you're experiencing regular crashes on a new Mac that's still under warranty, you should contact Apple. I've had random kernel panics on two occasions with brand new Macs and on both occasions it was a hardware issue that required a new logic board under warranty.

Swapping is to the boot drive, so if you boot from an external SSD the swap file will be there.

[@hypnosecoachinghombach7517]

I haven't tried it yet, but do I understand you correctly that I can run my Mac mini M1 from an external SSD via USB 3.1 or should it be Thunderbold? Can you use Carbon Copy Cloner to clone the internal SSD to the external SSD and then use the external one as boot drive? I'm doing that on my old Mac mini from 2012. But times have changed since then.

[@jonny777bike]

Thanks for the video. I have no idea why Apple would make the internal ssd a soldered drive, because what happens if the ssd internal goes bad. Then its a big problem to desolder it and then solder a new one in. They should have used internal m.2, but no. Im going to use the OWC Explore 1M2 for a 3100 MB/s speed.

It depends on the SSD, but with a USB 3.x Gen 2 drive like the Samsung T7 it's barely noticeable. With a slower, SATA drive in an enclosure you do notice a slight slowdown.

Thanks for the tut! Very helpful information. I have 2 questions and i hope someone can answer. 1. Does it matter if i use the cheaper DRAM-less nvme drives? Is there a performance hit and is it noticeable? 2. Can MacOS take advantage of the fastest nvme drive? Or will a mid mid priced nvme drive suffice? This iMac 2017 is used for graphics only. No video editing.

[@bigbubba0439]

For the first question, I would think that would depend on your cable (I'm not entirely sure, but that's my guess). As mentioned in the video, a cable in general, but especially a slow cable, can really make your performance take a hit (with the drive). Also, I have heard that DRAM-less ssd's can actually be slower than a spinning hard drive, so I would advise against it.

What external drive are you using? I used to have frequent random disconnects with my M1 Mac. It was due to the enclosure I was using. When I switched to a different enclosure, the disconnects stopped. Booting from the external drive won't stop the disconnects from happening if they're caused by the enclosure or the cable, you need to have a solid, stable connection if you're going to be using it as a boot drive.
