We all feel incredibly grateful too you for all the work you have done to allow our Mac's from the past to happily function into the future. Thanks again DD1.

I just wanna say, you are a hero of the internet. Thank you.

I just wanted to say that you are life saver! I needed to work from home 100% of the time because of the coronavirus going on right now, and my MacBook Pro computer was stuck on El Capitan, and I was not able to download the app that my job needed me to download to work remotely. However, I followed your steps and now have upgraded my computer to Sierra! I had no idea this was possible, and you made it possible for me. I should also say that you allowed me to work from home during this pandemic. I will forever be grateful!

Hi! I just wanted to say thanks! Because of your tools, I was able to get my new-to-me Mac Pro up to Mojave tonight after having a tough time trying to upgrade things this week. I found the tool and it was smooth sailing. I'm someone with no Mac experience and this has made things so, so much easier. Thank you!

Sir you are a genius. Thank you Kindly. you saved my MacBook Pro. Everything you said and your patch worked perfectly. I will make a donation.

You're an absolute legend my friend! I've spent around 4 hours attempting what you made possible in 20 mins! Jezzzuuuz!

Thanks you Colin for the time and effort it must of took you to work this process out, but also to document it so clearly both on your website and in this video. I now have my early 2008 iMac up and running and I now start the process of using my 2008 as a secondary monitor to my iMac 2013 running Catalina.

Amazing job, keep it up Collin!! if there were more people like you, this world would be better. I hope everyone is tipping. Thank you so much.

Thanks for the work that you do. Without these patches I would not have been as productive as I am. My macpro 3,1 is still the center of my world because of you. Thank you dosdude 1.

Absolute legend. You've single-handedly upped the resale value of many, many old Macs. I just upgraded my old man's prehistoric iMac 10,1 (late 09 model). About to shift it over to Catalina, though I might stick to Mojave for the 32-bit/non-APFS mandatory environment in case he wants to run legacy software. Gonna buy an old Mac to knock out some Apple certification. Will definitely donate to you as you've saved me literally several hundreds of dollars.

You're quite amazing dosdude1....def took a 2010 mac mini that had snow leopard and with your instruction, got it up to High Sierra. Many special thanks to you! Note: I attempted to try to reboot back to the installer but it always took me to the installation setup of High Sierra. Maybe because it is not in beta no longer, I am not sure but I was able to update High Sierra with the latest patches through the App Store. Either way, thank you again for being amazing.

The biggest issue for me with this model that I kept seeing for years before your work was that the Broadcomm Wifi card was not compatible with any method available before for installing a newer MacOS. The patches were the answer, I see. Fantastic work, thanks so much. After the installation worked, soon after there were updates to be applied that undid Wifi functionality. Reapplying the patches restored the Wifi.Overall, the machine runs faster than it has in years.

Your work in developing a solution for unsupported Macs is profound and amazing. Thank you taking the time to not only develop such a great solution, but also thank you for taking the time to make videos and provide detailed instruction. This has worked on 2 of my machines like a charm.

Everyone, thank him, not only with words, but with a donation. I gave him $20 which is less then fair. Not for the Mac 3.1 below, but for my Mac 2.1 to El Capitan. We don't want this programmer stopping the great thing he does.

I am INCREDIBLY grateful for you and this patch and video! My system was on High Sierra (late 2011) and needed a fresh install... nothing from Apple and no downloads would work. Because the patch allowed me to continue to resume downloads after getting kicked out so many times, I was able to get a verified installer and install SO EASY with your video and the patch.. Thank you so very much.

I just want to say thank you. I have learnt this process twice, now an expert. I know now, how to create a bootable installer 😁 Your thought out, clear instructions, are easy to follow. Genius! Works. Thank you, thank you

Thank you for making my College life 10 times easier to get work done. Thank you!

Worked on my 2009 iMac like butter 🧈 thank you so much!

OMG! When I thought I had to throw away an old Macbook we had home just to watch movies simply because the apps we need were incompatible, I discovered your solution and now I'm up to date and can squeeze some more life from this trusty 2008 unibody Macbook. THANK YOU!!

After a week of trying to get my 2009 iMac to see my iPhone, this was the key to finally getting it worked out. Thank you!

Thanks Dude!! I appreciate your efforts to help so many users. Great work. Apple simply wants more money, so they just cast aside, paying customers needing to update older models. You are a force of tech. Much appreciated.

Thank you so much this worked for my MacBook 5,1. You're absolutely getting a donation from me and a like on the video. This video should have a million views simply for how easy you made this process. Again thanks so much

Thank you 🙏. Setup my old MacBook for my daughter’s first home studio setup. This update solved all the version compatibility issues.

Just updated a previously almost worthless 3,1 box - and donated to you for your great work! You are appreciated!

Thanks was waiting for this one. My old 2009 Macbook 15" is gonna shine like a gem again.

Sir! You are amazing. I'm sure Steve Jobs will admire you. Thank you.

This worked perfect for me! I have a MacBook Pro 2008 (5,1)upgraded the ram to 8gb still running the disc drive. Everything works great. I totally recommend following the steps I did the direct update did not have any problems. Thank you so much man! You’re a true genius. You saved me tons of money from upgrading. The 2008 Mac book pro model is a good model i recommend this update!

Thank you! I wasn't able to update my mid 2011 iMac to High Sierra for years due to expired certificates (damaged download) and your tool finally made it possible

Thank you so much! I have a mid-2009 MacBook Pro. I’m taking a Swift App Development course this semester and was afraid I would have to buy another computer because Xcode was not supported. After following your video, I was able to install Xcode with no problems. You just earned a subscriber !

Your work is immaculate!! I appreciate all you do. My old Mac Pro 3,1 has new life!!

I tried this today on a £50, 2009 A1283 mac mini. 5gb RAM and 120GB ssd, already loaded with el Capitan. Worked almost flawlessly, the only issue was that I couldn't wipe the destination disk with el Capitan on it. Instead I upgraded and all worked well, really easy, I didn't watch the video before , just followed it as I did the upgrade. Thanks a lot for your time and effort to provide the software and the guides.

This is incredible. You saved my 2008 macbook pro. It not only saved it but sped up the computer again. Almost like new.

Dosdude1, you are awesome! it works on my 2008 3,1 Mac Pro. The only challenge I ran into was doing this from a usb stick. The stick would not show up as a bootable device. I then tried it on a usb hard drive and it worked the first time. Very happy, and thank you for all of the hard work you put into this patcher and interface. I have 3 of these machines and I can't wait to update the rest.

Love it, this totally worked on my early 2008 MacBook pro. Even the internet / wifi is working!! even though my model is on the list where you said wifi won't work. maybe you have an updated version now - but huge thanks!

Thank you so much, I’ve been wanting to do this and watch many videos and been hesitant about it but after watching your video I went for it! You explain every step and it was easy to follow so thank you !

Hey, I just used your patcher and instruction to install High Sierra on a 2008 MacPro3,1, which has allowed me to upgrade to the latest version of my preferred digital audio software. Brilliant! Where I come from in Scotland, Dos is a term used to describe something great, awesome, excellent and cool. So to me, you really are a Dos Dude! Thanks.

Fantastic little app that gave my early 2009 Mac Pro a new lease on life. Simple to use,even for non-tecnical people. I just sent a small donation to thank you for your great work.

You rocks, Dude! You have breathed new life into my secondary mac. Thank you!

Wow, it actually worked for me! I don’t know how, but it did. I ran into some issues, but just kept repeating the reboot steps. I figured if I was going to have to buy a new computer anyway, what’s the harm in a little trial and error. But in the end, I went to sleep with a reboot in progress and woke up this morning with an upgrade on my screen. You are a godsend. Will definitely be donating to your efforts. Thanks!

Thank you so much. It worked out perfectly, mac office 2011,adobe cs6 all working on High sierra. I subscribed! I am surprised you don't have over 1 M subscribers.

Thanks Man, still works in Nov 2018..

Thanz broe it's really works Surely there's nothing to complain. Thanks for your helpful video and procedures

Tried this and it worked 100% the first time. You are a saint sir. This made my client very happy.

Thank you bro. Upgraded to MAC OS high Sierra. You’re straight forward good at explaining. Sending love from South Africa 🇿🇦

work great! on my macbook mind 2009 so thank you from my heart :) :) :) :) continue your good work genius!!!!!!

Thank you so much! You're a genius

After ONE WEEK of endeless googling, trying to create a bootable usb from Windows machine and troubleshooting why App Store doesnt show any older OS versions and why my downloaded installer is only 20MB and not 5GB is finally over. THIS IS THE ULTIMATE SOLUTION. Works beautifully. I cant thank you enough for this tool. Without this, it would be a nightmare. I almost gave up. THANK YOU VERY MUCH! I hope that you're well.

By installing via bootable USB, you saved my Macbook Pro 2010! It took me a few tries but it did the job and worked beautifully! many thanks!

thx bro, I just made it on an early 2009 imac, working amazingly.

Thanks bro i just now upgraded my imac early 2009 to high sierra

Hey man, you are the best! Been trying to breathe some life into an older 2007 iMac for sound mixing purposes. I was so happy to see that your tool had the "Download latest version of High Sierra" imbedded in the utility, as all other means to acquire a legitimate install.dmg were futile for myself. (Didn't have anyone around with a supported Mac to download a legit version) Anyways, many kudos to you! Have a great rest of the year! :)

This is my favorite man, I'm going to dedicate a video to him.

Amazing work! not enough words to thank you! How do you do what you do?!

Thank you so much for your awesome work an tutorial! Just upgraded my cheese grater MacPro 3,1 in 2020 😁

Thanks. Running through a ton of videos, this was actually the one making it happen for me.

Just to think I was gonna spend 500 for a 2015 iMac just to finish school work... You are the real MVP BRO!!! Bravo... *Early 2009 iMac* running upgrade flawlessly. No fresh install...

hey so I'm having some target volume error any help on hw to get past that i have a macbook pro 8

PS: I almost forgot the sound of the older Macbook Pro fans until watching this video haha. What good times!

man i love people like you who makes such things. you saved so many people money and even more and you give all the information nessacry

Wow! iMac Early 2009 on my desk now running with High Sierra - worked for me! Appreciate it dude

Dear friend, your software is awesome! I installed it and it works like a charm, but I have a question. Apple has just released a very important security update. Can I install it from App Store? I know you can't install system updates from there after installing the patched version, but does this apply to the security updates too?

When i click on the ‘here’ link ive been stuck on a white screen

It worked!! It does take some time from start of downloading patcher to setting up your computer with sierra installed. I used a 16G usb flash drive. Took about 2 hrs.

This was wonderfully detailed and flawless! Thank you SO much. Just sent you a few bucks in thanks!

Hello! Thank you for this. I'm getting an error "The application you have selected is not a valid copy of macOS High Sierra." when trying to copy to USB. Any ideas? TIA

I get a circle with a line in it when I try to boot into the usb drive.

Thank you soooo much ! If we weren't in this unbelievable situation : i could hug you ! MERCI (from home in Belgium)

Thank you. Great video and step by step instructions. You've kept my Mac running.

how I can uninstall this version and back to El Capitan, I can't run well the programs what I nee. Thanks

Thanks a lot. Worked once for me like a year ago. now it keeps giving me "error coping files to usb" any solutions? Ive used 3 different usbs.

Donated in thanks!! This is SO helpful even six years later - I needed the video in addition to the website instructions and so appreciate what you do. I just got a 2008 iMac (8,1) I inherited at work to run High Sierra and thus make it usable again! One tip that might help others is that I kept getting a "no such place" error when making my OSX usb drive when I titled it whatever I wanted. I switched to an external hard drive that I partitioned with one section titled "OS X Base System" and that did the trick.

Got mine running. I had no success using a USB thumb drive onto an existing OS Yosemite. I'd bee trying to do a normal upgrade to El Capitan and ran into major problems with that, causing my system to fail such that I had to wipe are reload from Snow Leopard disk. I was completely fed up with that and decided to try your solution. I was successful using a Firewire 800 enclosure with a 1 TB hard drive. I also wiped the destination drive, reloaded the recovery drive onto the boot drive and then installed according to the instructions and was successful on my test boot drive and I'm not installing on my SSD boot drive. I'm very happy now and just need to replace an updated bluetooth/wifi card and I'll be done. Thanks again. Great stuff.

So I have a iMac mid 2009 and when I am rebooting it to the flash drive it takes for ever and then it starts to slow down half way thru the boot up and when it fully loads it just stays on the boot up screen until I restart the computer please help me

After process complete, restart, alt/options doesnt work for me. Got the 🚫 sign again and again. Tried cmd + r still doing nothing. Please help..

Works brilliantly on a 2008 3,1 Mac Pro. Limited to 50GB RAM if you’re having trouble booting with 64GB. Thanks for keeping my Mac alive!

My issue was I downloaded Mac OS High Sierra after I attempted to update to Mac OS Mojave on an unsupported machine (12,2) and it was a disaster. I had to restore using Mac OS Lion and had extreme difficulty with Safari as it would not open any sites with the Mac OS installers that I needed. Somehow I was able to get High Sierra but it now caused my machine to restart loop, or boot then restart and would do this randomly. Nothing on KZfaq worked two weeks passed with me sitting here all day attempting to repair my Mac. I narrowed it down to an incomplete High Sierra Installer and used your tool to create a bootable disk and did everything you said to the book Except perform the Mac OS Post Install. So basically skipping the patch selection since my machine wasn't listed. Installed to my internal boot drive and BAM Mac OS Sierra is stable. Thank you from the bottom of my heart.

Hi. I keep getting an error when starting operation. It reads “Please make sure drive is formatted correctly” and it is. I’m currently running your patches Catalina but I want to downgrade because some apps won’t open or function correctly

Mine says restore error. An error occurred while restoring basesystem image to the target volume What do i do.

I just tried this out on my early 2009 Mac Mini 3,1 a couple of days ago and it works quite well, the only issue I have found so far is when I do an OS update the WiFi doesn't work, so I reapplied the patch and it came back again. This really helps with all the apps that I couldn't get support for because it needed Sierra or higher to run their updates, thanks.

Just installed High Sierra on my 17" MBP 2009/10 5,2 . All seems to working very well so far. I upgraded from El Capitan as this was the last supported OS. It's taken me a few hours to install following the video & adapting it as the video is 4 years old. It seems some of the bugs have been ironed out since then. I have no problem with wifi, the trackpad, backlight & keyboard backlight, it all seems stable. I had previously tried installing Big Sur but I found too many bugs with my machine. Many Thanks Mike

You are the boss! ;)

Hey thanks men¡¡ it really works pretty good in my 5,1 late 2008. How about new archive system, is it change in my machine?

Thank you so much for this solution. This helped me to resolve the keyboard problem of my Macbook by installing new macOS High Sierra.

aye bro you smart as hell, your delivery is awesome and your q&a on your site is so professional G. Good shit

Everything worked until I clicked „start operation“ cause as soon as I clicked it a sign pops up saying „mounting failed. Please check your macOS high Sierra installer app, them run the tool again.“ And I did that but it still doesn’t work. I’m so confused. Please tell me what to do. I want this to work. PLEASE.

Hey so I didn’t erase my hard drive so I continue as a upgrade and I did everything and did the reboot and it gave me this sign --> 🚫 what do I do

Thank you so much! The web-based instructions were a tad daunting, but this video is perfect - really appreciated, and has given a new lease of life to a 2009 Macbook Pro 5,2 that was close to being a brick beforehand, despite its original eye-watering cost. I nearly fell at the final hurdle when I couldn;t get past the Terms & Conditions screen, but I found elsewhere that skipping the iCloud log-in alleviates this problem. Many thanks again : )

This is great! I enjoyed getting my 1,1 to El Cap, now I have my 3,1 on HS. THANK YOU SO MUCH!

hi, I'm having an issue using this tool on a late 2008 macbook 5,1, core 2 duo 2.0ghz and 8gbs of Ram. I always get the computer to boot from the drive but I always get stuck at 15 minutes and get the message Macos could not be installed on your computer. what am I doing wrong?

I have an SSD drive and want to PREVENT conversion to APFS which the High Sierra GUI installer does automatically. On supported Macs, this can be done using the following command, which you run in whatever directory the file "Install macOS High Sierra.app" is in: "Install\ macOS\ High\ Sierra.app/Contents/Resources/startosinstall --converttoapfs NO". This is a command-line command to type into Terminal in the bash shell. If running from macOS normally you need to put "sudo" in front of it, but off a USB installer you leave off the "sudo". Anyway this does not work with your patched installer, your patched installer is not compatible with the "startosinstall" command-line OS installation utility which allows APFS conversion to be DISABLED on Macs that have SSD drives such as my particular late 2008 Aluminum Unibody MacBook (MacBook 5,1). I want APFS disabled, among other reasons, because it does not work with a Recovery Partition with your tool, because it is not supported by any other operating systems whereas many tools to read and write HFS+ exist, and basically, I just want it off and I want a working Recovery Partition. Also why isn't your Recovery Partition patch ON by default? I see no point in having it disabled. It is necessary for the recovery partition to work. Is it because your post-install tool is not installed on the recovery partition, so the recovery partition has the potential to mess things up? If so, maybe you could figure out how to get the post-install tool included in the Recovery Partition. Anyway I hope you read this comment, I am going to put off upgrading from Sierra to High Sierra until you get your utility to support having APFS conversion turned OFF when doing an upgrade, which you would do by getting the "startosinstall" command-line utility INSIDE the macOS High Sierra app package to work again. Right now that tool is broken in the installers created by your utility, which is a real shame. The unpatched version of it from Apple DOES work but ONLY on Macs officially supported by Apple, unfortunately.

Followed all instructions, made sure all was compatible, did all the post patches and it still wiped my system!

I dont usually post commenté in KZfaq but tais really desserves one. Installation was smooth as butter. Thank you so much!

Geez people! This guy is providing an awesome service free of charge, complete with the software tool and full instructions. And all you can do is bitch at him because you fucked up and can’t follow simple instructions? You should be thanking him! Don’t attempt something you’re too stupid to achieve. All I can say is r/ChoosingBeggars

Does the brightness control now works? I saw on your website that the particular issue is not listed anymore.

Just wanted to say thank you! I bought this MacBook Pro for 20€ and now is like new! Very helpful 10/10 🙌🏽👌🏽

Updated two late 2009 Imacs to high sierra, thanks so mucht for sharing this amazing solution

Why can I not update iTunes via the App store ???

DosDude, You are so goddamn brilliant. I've been having THE WORST time trying to get High Sierra on one of my 27 Inch iMacs (which IS supported - its a like 3gHZ i5!). Main Issue was I had formatted the entire HDD to NTFS since I had pretty much given up and was running 8.1Pro. NOthing worked to get OS X on. Been through 9 different bootable drives, External "SuperDrive" or w/e Apple calls it with real OS X DVD's. The only thing left was to hook up the machine to one of my other Macs and try whatever WitchCraft you can supposedly do (bet it wouldn't have worked). Last night I thought back to using your High Sierra process on an older iMac forever ago. Long Story short, Made the bootable dosdude High Sierra Fyre Piff and we are iSet! Thank You x 100000. =D

YOOO end of '23 and I was able to get it on my 2009 mac mini. this vid helped A LOT. had to keep resuming the os download but it worked nonetheless. Very awesome

Thank you for the video, this tool has helped me upgrade to be able to use a program that wouldn't run on my machine otherwise. Thank you for your time and work! Gracias!
