How to Create a Mac OS USB Boot Drive on Windows
HTML-код
- Опубликовано: 4 июл 2024
- This tutorial will help you create a bootable USB flash drive for your Mac on a Windows computer using Transmac.
Please visit www.kevinmuldoon.com/create-m... for a more comprehensive overview of the steps you need to perform.
In order for this to work, you need a USB flash drive. The one I used in my tutorial was 16GB in size, but it should work with any flash drive that is 8GB in size or higher.
Open command prompt as an administrator and enter the following commands to convert your USB drive from MBR to GPT format:
diskpart
list disk
select disk X (where X is the number of your USB flash drive)
clean
convert GPT
create partition primary
Transmac can be downloaded from AcuteSystems.com at www.acutesystems.com/scrtm.htm
The application costs a one-off fee of £59, however, you can use Transmac without any restrictions for 15 days. That's more than enough time to do what you need to do.
Another program that you might find useful is HFS+ for Windows (by Paragon Software). It's available at www.kevinmuldoon.com/go/parag... and is compatible with Apple Boot Camp software. It also gives direct read and write access to Mac partitions.
The DMG file for Mac OS X can now be downloaded free of charge from Apple.
Mac OS X El Capitan - support.apple.com/en-gb/HT206886
Mac OS X macOS Catalina - support.apple.com/en-gb/HT201475
Mac OS Downloads - support.apple.com/en_US/downl...
Once you have your USB boot drive, you can boot up from the drive by inserting the USB drive into your Mac and then pressing the option (⌥) key as soon as your computer loads. This will allow you to select which drive you boot from.
If you see the no/prohibited/forbidden symbol after selecting your USB drive to boot (it's like a circle with a line through it i.e. ø), try and go back into the recovery area by pressing command and R when your Mac is loading and unmounting the drive.
There is a good discussion about this issue at forums.macrumors.com/threads/w...
Some people had better luck entering into safe mode using command and S - see the discussion at forums.macrumors.com/threads/c...
There is a lot of great information about the prohibited symbol at bombich.com/kb/ccc4/help-my-c... too.
I'd love to hear your thoughts on this so please leave a comment below. As always, if you enjoyed the video, please click like, share, and subscribe :)
Thanks guys.

I use window and how to download macOS Catalina ?
@@gameeiei9842 if you can't download it directly, download an earlier version and then update it from the Apple store once everything is set up.
Kevin Muldoon ok I will try
after that can we download files to bypass iphone activation? from ivory coast
I never faced that step myself when I did this tutorial.
Quality walk through, I spent hours wasting my time looking at other howtos all of them missed out soem important step. Great use of DiskPart BTW
Thanks the only person I could understand that was doing it on a Windows computer
I subbed
+Chris Boyer You're welcome. Glad you found it useful :)
+Chris Boyer Thanks Chris. Good to have you on board.
Chris Boyer for real!
ikr same. all of the other tutorials i saw, said to download it on another mac.
i was looking for a video like this for months now, this was so helpful.
Thanks Kev, even for an IT minded person like myself having these steps nice and simply laid out just saves a lot of time and is much appreciated.
You're welcome. Glad you found them useful.
How did you download I couldn’t find macdrug
This was a huge time saving for me. An elderly lady had issues with her iMac and I didn't know how to rescue the iMac without a disk. Thank you so much for your most informative video.
Command + R on boot up, you will get into recovery mode and can restore the device with internet connection.
@@jj987987987 that doesn't work with some older version of mac os
@@Z00TS older versions are more convinient to do recovery boot with a mac dvd and hold c while boot up. Or have a external mac drive and boot up while holding options.
Jordan Wu do you think people would be trying to create a bootable USB if they had the cd or an external Mac drive... yeah... no!
Thank you so much. Took me forever to find a decent tutorial on this. If only I had but more than one like to give
You're welcome 👍
This was my first time reinstalling macos and this tutorial was definitely the easiest to follow. Thanks for uploading
You're welcome.
Can I just say you came at the right time like God. I installed Mojave on my unsupported mac and all hell went loose, kept booting into recovery mode. You helped me out from selling my iMac. I just want to say a really big THANK YOU!
You're welcome Zinx. Glad it helped you out.
Hey there Kevin! Thank you soooo much for this awesome video! It was so easy to follow with simple instructions, not like some others out there. It took me around 5 minutes to create the bootable USB. Thanks again so much mate!!
You're welcome.
@Ande Visagie Can you share if this process worked for you. I'm one of many that are having an issue with our Mac ready the USB. Thank you.
Rpac17 hi yes it worked perfectly for me. I just followed the steps in the video. I’ve didn’t have any issues.
@@addysgb I appreciate you answering.
I just wondered why many of us are experiencing our USB's not being visible during the reboot.
Thanks again I'm glad you found success.
Rpac17 I’m not sure. I’m going to do it for a friend when this whole lock down thing is over. I’ll let you know how that goes
Kevin, this is a great video. I'm a PC guy and no one makes it more clear how to get to the point that you've done with this video. Great work.
Glad you found it useful Lonnie.
Fought this system for forever. Thank you so much.
It worked for me, you gave simple instructions and were right to the point; for that you have my like and comment
Just sold my iMac on eBay & went to do a simple reset. Made an absolute howler of a job & I'm hoping your video helps. First & last Mac I'll ever have.
Same here except I have a 2006 macbook. Went to reset it and it's been so freaking difficult just to get it to see a bootable usb
:) Why first and last dude?
GOD BLESS YOU Kevin for making this video.
You're welcome.
Thank you for making this video, I’ve been trying to find/ digit myself for days lol...as others have said your the only one to explain this process in a way anyone could understand
You're welcome.
great contribution for those who despite all the efforts could´t make it until we saw this really solution, congratulations
Thanks for taking the time to do this video. Am having to reinstall Mac OS High Sierra, it's been a nightmare Downloading from the apple store download would hang. I had to buy a copy via ebay then for nearly two weeks I had constant failed to download message from Google. And I was having to re download every time a download was interrupted. This was due to having a rubbish broadband service from BT !
+Nicholas Logan Oh man that sucks. I always found downloads from Apple to be really slow too, regardless of the speed of my internet connection.
Did you get it resolved in the end?
Thanks so much for this tutorial, really got me out of boiling water.
THANK YOU THANK YOU!!! I messed up putting Ventura on my iMac and you just saved me from having a much bigger headache!!
Cheers mate,by far the best tutorial on RUclips, this is the only one that works,you're a star.
+rustyrob Glad you kind it useful Rusty :)
Really informative and damn I love his accent
Thanks, guys. Quick and easy to follow directions.
years later and still works! Thanks!!
You're welcome.
4 Year old video helped me out lol. Cheers mate :D from Australia!
Glad it helped. Hope things are good in Oz 👍
@@KevinMuldoon IT did cheers. Yeh mate just bloody HOT as usual .
Haha Last time I was in Australia we spent Christmas in Melbourne and it rained for a week. The gold coast was crazy hot though.
Thank you sir, I've been struggling with creating a macOS boot USB without having a MacOS device
Did it worked for your mac ?
@@ironfan6005 100% Yes, but the virtual machine will only run on an Intel CPU, It won't work if you have an AMD CPU
7 years in the future, thanks so much!!! You legend!!!
You're welcome. Glad it helped you 👍
Please do a part two where you show the actual install procedure. Your videos are extremely informative and helpful.
Unfortunately, it's not something I can do as I later sold my iMac.
So many guides never mention converting to GPT. Thank you so much, I've been pulling my hair out trying to figure out why transmac was giving me an error. 🙏🏼
You're welcome.
@@KevinMuldoon wat key of the keyb oard i have to prees to install
i have a white screen whi a folder in the midle i replace the hard drive whit a new one just need to reinstall again
@@juliomonserrate8637 press option key
I cant believe how niche this answer is. you saved my ass
After been trying many methods, this was the only one that worked for me, thanks a lot
+Camilo Camargo Glad it worked Camilo :)
this gpt conversion nobody shwed in dier video only rare people like u who really wants to shw how to do it ,did with a-z procedure thanks man
Bro,be blessed
Its very nice. Make video for how to run that bootable USB stick.
Yes need that video too .
thanks so much, i find myself decent in it stuff and all other tutorials were confusing,thanks for laying out the steps clearly and perfectly
You're welcome.
I didn't search for this solution because I didn't think it was possible. I've been trying to do this through OSX and vmware for 3 days to upgrade an older macbook . Your solution helped me figured out in 10 mins. This is why Windows is still the best OS. Thanks much
You're welcome.
Just curious as to why you didn't use the format option in TransMac instead of terminal?
thanks for the video! It was simple and amazing! I´ve downloaded the .iso version intead of .dmg... Do you know if it is the same steps on TransMac? Thanks again
Where did you get the .iso version?
this helped so much when everything else was useless. awesome. thank you
Thanks Kevin. That was brilliant very straight forward no nonsense and irrelevant talking. Well done.
You're welcome. Glad you found it useful.
For everyone having issues with the USB not appearing, you need to make sure you have used a 2.0 USB and not a 3.0. You also want to make sure that the OS version you are installing is the one that your computer came with as factory new.
still doesn't show up
Why not?
This advice helped with my MacBook Pro, Mid-2010. Thanks a lot!
Watched this video 3 days ago i since then i keep randomly saying "Transmac" in a strong Scottish accent for no reason lol
You're halfway towards citizenship!
Thank you so much! I was trying to install old macOS versions in my computer, just for the nostalgia and my computer was having a lot of issues creating an installer for Sierra, El Capitan and Yosemite.
Great, A good clear and fast to the point explanation. Thanks for that!
You're welcome George.
nice job, but you omitted to actually test the USB on the Apple machine, it would have been nice
because he knows it will fail.
Haha yeah ok 🤣
mines failed. Wasnt being recognized by the mac
Mine didn't work but i did everything right
@@KevinMuldoon Yeah there's a few of us whose macs aren't recognising the USB - what's the fix?
Now the question is: can you keep reinstalling Transmac with a new trial?
By using vpn
This is the best guide I’ve found, thanks and keep up the good work!!
Thanks soc 👍
tried several ways to install mac OS in fresh hard disk, but the way you have explained has worked. Thanks
Glad it helped.
Please help I can't boot using the Drive, when I press power then ALT, only thing that show is the WINDOWS OS..
Make a backup of ur windows os, then do command+R, and format ur ssd to apfs or hfs. Then plug in ur usb, and hold option key.
I get "decompression error" when i do the steps with TransMac...
Bad flash drive.
Thanks for your info! Got stuck with the flashing "?" folder and needed this in a hurry to get back to podcasting and making music and videos. Thanks for your straightforward steps on how to fix the folder with a flashing question mark on MACos.
It worked on 4/27/2020 great job and the video quality was great.
hi, where did you get the dmg file?
I did everything as mentioned, but when I restart my mac holding down the option button, it doesn’t show the second option (the usb one), it only shows recovery mode HD...please help
Did you get this resolved? I'm having the same issue.
I have the same issue. Please help, I have tried many different versions of Macos and none of them works
Same issue
it says the disk image is damaged. can you help me fix it?
Try disk repair
Easy to follow thanks from the heart ..... next step formatting that Mac ...finding another video on RUclips demonstrating thhaaaaat
Thanks a lot , that was very helpful and clear ! I really appreciate you taking the time to make this video
You're welcome. Glad it helped.
So i get the DMG file on the USB following all of the steps, and when i boot to the disk select to install the OS, it's just not listed there. What am i doing wrong?
Did u get it solved ?
Me too
Download ISO file
@@jongdemarijn could you be more specific with this solution? I am having the same problem. It doesn´t recognize the usb
lucas lopez lax Download Windows ISO file instead of DMG
I followed the instructions on two (2) separate flash drives, but when I go into the startup manager it doesn't show either of them as an option to boot from. It just shows the grey screen with a mouse pointer. (It doesn't show a HDD because I just installed a new one without an os on it yet.) Ideas?
im looking for the answer too, so if you found a way, please let me know :D
@@relcse did yall find the answer, i have the exact same prob
@@TeamPxL did you?
@@edindzafic3713 I think I have fixed my problem. But what are you having a problem with?
I think you put a lot of work into this. Thank you very much!
You're welcome.
brilliant thank you so much, old post but you explained perfectly ! i am normally a windows user but my imac hard drive crashed, and wasnt sure how to reinstall os on new drive and this is start , new learning curve for me, thank you again
You're welcome Marc
Hi Kevin. Thanks for the video. Iam having troubles finding the USB from the booting meny. The only drive I found is my own drive and there is no USB in the list?
found any solution ?
Yes i downloades from piratebay and Made a boot usb
@@XeoN424 could you send me the link to magnet file ?
@@DrShobeir hi I don't have the link.
I made the bootable usb and when i tried to install on my max it says “ this disk doesn’t use the GUID partiton table scheme , use utility disk to change partition sheme.” When i try to do it it says partiton cannot me modified
same problem im facing
any help
Because you need to buy a USB stick that supports GUID?
You need to erase the disk and select guid.
@@camdenrush5472 how would you go about doing that????
@@merisajacobson314 you could "erase" in disk utillity on your mac, or "clean" it on a windows machine
Thanks bro. Quick and easy
Life saver video! My Macbook Pro network died so this is the only way to do it and it solved my issue. Thank you so much man!
You're welcome.
can you help when i try to restore disk drive it says that the usb is either damaged or un supported format
I got the same error.. :(
I did this exactly but the usb doesnt show up on the macs list of bootable drives when I hit the option key
am having a similar issue.
Same issue ... Any solution ?
Same problem here. Anyone got fix?
Same problem, any fixes/suggestions would be much appreciated
I’m wondering whether it’s my usb stick!?. Read that the Mac plays funny with certain usb pen’s, and that a Kingston 16gb 2.0 is recommended
thanks man, been a great help so far, havent put the usb in the mac yet but we shall see. this is the farthest ive gotten so far.. who knew pawn shops would rather format the ssd rather than just reinstall MacOS
Hey Kevin, just want to say thank you very much for this video. I managed to reinstall Mac OS with the help of your video.
You're welcome. Glad you found it useful.
Did u install it on Macbook pro??
@@leylam9233 yes
My (early 2011) macbook pro doesn't recognize the usb drive on boot, any help?
did you solve it ?
Mahmoud Hakim not really, I changed my router DNS and used the internet recovery.. it worked.
Hi Quang. Mình có mac 2007. Bạn có thể giúp mình recovery với.
I follow all steps in this video, with the only difference that I downloaded El capitan DMG from apple site, but when I try to boot from this USB boot drive created does not recognize it
Did you fix it?
@@alexmaciel1054 Sam problem here
I've tried using this method with four different dmg files. I've used disk part to make sure the drive was GPT with a primary partition. I've tried using the option in TransMac to "Format Disk for Mac". I've used different flash drives. I can never get the Macbook to see the drive when holding the option key at boot.
Jimmy Dalton I just wasted hours doing the same exact thing. This whole video is bullshit. My Mac won’t install the original OS via internet recovery so this is my last option and the shit still doesn’t work.
@@Killian665 Hey there, if you find any solution to the same problem please share.

Very helpful! Thank you!
Worked for me!! I am new to Mac and bought an old iMac mid 2010 as a project. After watching your video I had some trouble installing, but after a doing a little research I was able to finally boot from the usb. Thanks for the video!

Thank you for the great walkthrough. I'm trying to re-purpose an old Macbook to install Linux on it. I used the first part of your guide to prepare my USB flash drive for booting from a Mac then used another tool (Power ISO) to burn a Linux ISO on to the USB drive (using Raw file writing) using my Windows PC. Worked like a charm!
Hey There! I'm Trying To Install Linux On My Old Mac As Well But After I've Installed To The Hard Drive It Keeps Freezing On The Grub Command Line. Can Boot Up Just Fine From The USB But Not From The Hard Drive. Any Suggestions? Thanks In Advance
@@gamingpotatoza8975 Hey there. I had the same issue with one of the distros I tried (might've been Manjaro but I can't be sure now as I was testing a handful of different distros). The ones that worked fine for me on my old Macbook Pro (2008 model) were Linux Mint & Kubuntu. So if you don't mind changing distros, you can try one of them and see if it works for you.
Got the USB drive working. THANK YOU by the way! ok... third edit and slowly figured out all the issues! Got it booted up. Woot!
Glad you found it useful. 👍👍👍
what I actually ended up doing was putting a bootable img on a 128gb usb with transmac then once I'd booted the mac from the usb, the reinstall is working a treat. I inherited this mac and I doubt my friend remembered what her password was so I'm very thankful for your well explained answer.
Thanks mate! Very helpful.
Wow. You are a life saver. This worked perfectly.
Thanks a Million you saved my Mac tried other videos no joy big headache. This worked first time perfect Can't Thank you Enough ))))
