IMPORTANT TIPS: 

1. You can download the OpenCore-Patcher.pkg file instead of the GUI file - OpenCore is transiting to this method but either should work for now.

2. It's best to go with a 32GB or larger flash drive unless you have to use a 16GBG.  Mine was 64GB.

3. Choose the options at the boot menu quickly (or just don't let go of the option key) or the computer will autoboot on it's own. 

4.  Make sure you have at least 30GB of free space on your hard drive before starting the install - check after creating the bootable installer.

Have fun on Sequoia! :)

You've just saved my business thousands. I can't thank you enough. Wow. Even for a 51 year old dude, I managed it and works a treat. Seriously, my next trip out was to buy two new 27 inch macs.... Thank you

@sharonleibel

You saved me an $1500 upgrade from my Late 2015 27" iMAC, to a new Mac, on the worst time ever! for this expense! I had to reinstall everything, Which took me a few hours, But it looks the same now, And I can update my apps to their latest version. 😘 Thanks!

Unbelievable!  This is the first time ever a step-by-step Youtube tutorial matched exactly to the actually process.  The only difference was at the last few steps where he says you don't have to do anything while your system reboots two or three times and to just be patient.  In my case, if you have a screen password, you have to enter it each time.  But, that's it.  This tutorial is perfect, detailed, and easy to follow for anyone (I'm 62) and it actually works!  Anson has an amazing speaking voice with an exceptional talent at relaying the information succinctly.  All of the on-screen prompts matched exactly, no surprises.

This project started when I bought my kid the new Touch ID keyboard for her 2012 iMac.  Touch ID didn’t work. Learned Touch ID only works with silicon Mac’s.  Then learned the volume buttons on the keyboard didn’t work unless you have Sonoma.  Then ordered a 2019 iMac i5 with 8GB of ram from Amazon.  3 days later, received a 27 inch 2017 iMac i7 with 64GB ram and 2TB ssd drive.  A few years older but specs are way better. Ventura was the highest it would go and the keyboard buttons still didn’t work.  Found this video and got an error on the usb build with a Samsung flash drive. Tried another flash drive and it worked.  Now on Sequoia and the Touch ID keyboard is working. *I didn’t do a fresh install, I installed over Ventura. So far so good. Much love from Colorado

I was weary of doing this because it sounded too good to be true, but I needed the latest macOS to download Microsoft Word for school and it wasn’t letting me due to it being 1 year too late to be compatible with my version… and honestly, this was the best thing I could’ve done, saved me $600+ buying a newer laptop. I did this on my 2017 MacBook Air and I’m so happy!! It works like a charm. The only downside was it took me 4-5 hours and multiple tries but we got there in the end. 
Highly recommend doing this and saving yourself $$$ 
Thankyou so much 🎉

For those who are contemplating a "clean install" option (from 5:44), I have a few pointers. Before you wipe out your hard drive , make sure to logout from your AppleID so your device won't go "missing". For MacBook users, your wireless connection may not work right away (along with laggy and ugly graphics display) until you update the drivers with the root patches, so you should copy the "OpenCore Legacy Patcher" app on some USB drive to patch your MacBook off-line. Otherwise, you have to download/troubleshoot using wired Ethernet, so a thunderbolt-to-Ethernet adapter is handy. With a few detours, I successfully upgraded MacBook Pro 2015 Retina from Monterey 12.7.6 to Sequoia 15.2 with the help of this video. :)

@beck8480

DUDE! I know every comment is a reflection of how awesome you are, but I gotta add to it!!! I had succumbed to having a 2013 iMac and just knowing I would never be able to update. I’m a freelance media professional and keeping my programs up to date is important in such a fast paced digital world. I’ve been going back and forth on buying a new computer before finding this video. You have made my day… my week… my month! Absolute shoutout! You are a rockstar!!! Life changing! Thank you <3333333

@seansibbett3226

I have to say this has got to be one of the best videos I’ve ever seen on YouTube. You just saved me $1000 from having to go buy another Mac to do my taxes. You’re the man!

@pappy4dolly

My old 2012 Macbook pro still firing thanks to this wonderful tutorial! Just remember to do the 'Post Install Root Patch' otherwise your computer may run very slow.

@ThierryJourget

I wanted to congratulate you on the quality of your video: precision, seriousness, pedagogy are there. Great art!!! Few videos of this type are at this (high) level. I laboriously translated your entire comment (I'm a frenchie...), I watched the video several times and I embarked on this adventure which lasted part of the night to bring everything up to date (updates, ...). I now have an external SSD that boots on Sequoia. After studying the "clean" update, I plan to install all of this on my internal drive. Bravo again and many thanks !!!

@bjrnskjrup7961

You are a living legend, Anson!  

Your guide just saved me a ton of money. I'm a freelance journalist, and I was beginning to save up for a completely new iMac because my 2017 27" was "stuck" on supported macOS 12.7.6. But thanks to your guide, my iMac now runs Sequoia 15.01, just like my much newer MacBook.  

The installation got stuck at 28 minutes the first time I tried, but I rebooted, and then everything went so smoothly! The iMac might be a little slow on startup now, but that's it!  

Once again, thank you so, so much!

@JoseRenatoRecalde-gc9sk

Thanks Anson, excellent video.

@skippyFL1

When I discovered I needed to update to Sequoia to use the 2024 Turbotax, I bought a mac mini m4 to do my tax returns as my 2017 Macbook Air 13" was at the end of the rope with Monterey.  Your youtube video, which I only discovered a few days ago, was easy to follow and I was able to update my MB Air to 15.4.1.  I'm not seeing anything negative after the upgrade. An added benefit was that MS Office suite can now resume receiving updates, whereas, it was no longer possible with Monterey.   I now have an updated laptop with a new life that I can continue to use when I am away from home.  I luv it!  Thanks much!

@abdullahaalmutlaq5868

Thank you so much, Anson! I can't believe I actually did it! It took me about 2-3 hours, and I was kind of panicking the whole time, worried that I might mess up a step or lose any files. But I got through it—thanks a lot, Anson! Notes for your followers:
1. You may want to do this with two screens and in a quiet area to pay attention to the entire video. I went to a library and used their computer to watch the video while following the steps on my Mac.
2. Expect to spend around 2-4 hours; relax and grab some coffee so you can focus.
3. Do not rush; if the pop-up message hasn't appeared, just wait a bit.

@BrokeandFamousPR

Thank you for the tutorial. The installation went smoothly on my macbook pro 2012.
Surprisingly Sequoia runs smoother than Catalina from freaking 12 years ago.
😱

@megamega77777

Amazing tutorial! My wife got herself a new iMac M4, and I took her old MacBook Pro from 2015. I installed Sequoia on it without any problems using your tutorial here. Everything works great on this 10-year-old MacBook! Of course, it's not as fast as the M4, but hey, for everyday work, internet browsing, and even making music in Logic or Ableton, it's perfect. Thank you!!

@bobibobio1999

Mac Pro (Late 2013) "trash can" here. Everything worked! Thank you so much for the tutorial.

@nielsspijkerman329

I successfully did the installation today on a MacBook Pro early 2015 (A1502). All went well and Sequoia 15.5 runs smooth on the MacBook with only 8 GB of RAM. Thanks for the video Anson.

@mikecouture7969

Let me tell you this was a lifesaver I bought a 2017 iMac and couldn’t use logic or any of my Adobe apps because it couldn’t update further. Doing this not only can I use those apps now I was actually able to migrate from my MacBook to my iMac now that they’re on the same os. This was awesome and simple with your step by step guide. THANK YOU
