Sonoma

Reinstalar Sonoma

Não consigo criar um instalador mesmo copiando exatamente as linhas de comando passadas pelo suporte, com alguém já deu certo? Fazer isso em um Pen drive maior formatado?

MacBook Air, macOS 26.1

I can't create an installer even after copying the command lines exactly as provided by support. Has anyone had success with this?

Follow the instructions in the following Apple article exactly:

If you have any errors, then please post the complete error message here since it may provide us a clue to the problem. If the error involves the command used in the Terminal app, then make sure to also post the complete command used (copy & paste the text for the command & the error message is best in case we need to translate it, but a screenshot is also good).


Should I do this on a larger, formatted USB drive?

You only need about a 20GB+ USB stick. The most important part is using a good quality USB stick since most USB sticks are junk.


Recent Macs have access to Internet Recovery Mode. See the instructions in the following Apple article:

FYI, people should always provide the exact model of their Mac when asking for assistance online since that information is usually required for proper support. You can get this information by clicking the Apple menu and selecting "About this Mac", or if the Mac won't boot, then use the system serial number on the Apple check coverage page here, but please don't post the serial number on the forum since it is considered personal information:

It also helps to know the current version of macOS that is installed on the Mac as well as the reason for needing to reinstall the OS since that reason may be why you are having problems with the installer.

Predicated on your user byline MacBook Air, macOS 26.1


The computer is running macOS 26.1 Tahoe 


Your question is placed is in macOS 14 Sonoma 


So, what version of macOS  are you trying to create on a 64 GB USB Flash Drive ?


Is  the Flash Drive formatted to HFS ( Journaled ) with a GUID Partition Map ?


Do you have the Full Version of the unknown version of macOS located in the Applications folder of this computer ?


When you run you command, is there an error message ?


If Yes, what does the error message say ?


Using this Terminal commands, which I have used successfully do work for me 


The /MyVolume in each of  the commands should be the name given to the Flash Drive 


Tahoe macOS 26 via Terminal 


sudo /Applications/Install\ macOS\ Tahoe.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume


Sequoia macOS 15 via Terminal 


sudo /Applications/Install\ macOS\ Sequoia.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
