I need to download macOS Catalina and make a bootable USB for my macbook pro 2015 which has intel chip.

But have only m1 chip macbooks here, can't download from app store. It says

Not compatible for this device

I can't trust any source other than official one. So I can't download from torrent.

Is there any workaround.

Thanks

You can use MDS : https://twocanoes.com/products/mac/mac-deploy-stick/ to download Catalina, then create an usb install key using this : https://support.apple.com/en-us/HT201372

Note that this key must be created with a GUID partition scheme.

  • this method is only for downloading. We can't create a bootable usb of macos catalina or older macOS under an M1 chip. Actually the main problem was internet connection of intel mac. In this scenario I have to move downloaded dmg to an intel chip mac. – msalihbindak Oct 31 '21 at 20:33
  • @msalihbindak. Once downloaded the dmg, if you open it, you will find into the directory Applications, the installer. app and the createinstallmedia procedure work fine on M1 under Big Sur. –  Oct 31 '21 at 21:08

Download Big Sur or Monterey to M1 Mac. Create USB installer and install on Intel Mac. Download Catalina to Intel Mac. Create USB installer and install on Intel Mac.

I can also refer you to the question How can I download an older version of OS X/macOS?

  • Downloading BigSur takes hours in my internet connection because of its size and I don't want to use bigsur. just catalina is ok. Thanks anyway :) – msalihbindak Oct 30 '21 at 10:03
  • Not really useful as many Intel Macs do not meet the cutoff to run Big Sur and can only run Catalina – user1950278 Apr 18 '23 at 09:00
  • @user1950278: The OP has 2015 MacBook Pro which can run Big Sur. My answer is based on the question being asked. – David Anderson Apr 18 '23 at 11:16
