Disable Mac's white screen on startup without OS X live dvd/usb

sens · 04-19-2022, 11:39 AM

I installed arch linux on my 2007 iMac(deleted macOS completely) but when start it, a white screen appears for a whole minute, then GRUB starts.

The solution for it is to boot to live OS X cd/usb and run the command ```bless --device /dev/disk0s1 --setBoot --legacy --verbose``` in the terminal.

But i dont have the OS X bootable dvd/usb nor i have any device running macOS.
Is there an alternative solution for that using any linux distro's live iso? Or can I create OS X installation media in a usb without macOS

There's more if that doesn't help.

I have already seen them, the arch wiki says that you have to boot through the live dvd or have a macOS running device and i dont have any of them.

I am thinking to install an iso image from internet and make bootable usb through it.
My iMac most probably run OS X 10 Leopard and I need its iso

sens, Might there be a local Mac club from which you could borrow MacOS installation media from? A reader here who is near you might offer one if your info block included your location.

ondoho, why all the whitespace above and below Слава Україні!? Seems like 5 lines before, 3 after.

Means your system is unable to display color emojis properly. You should get that checked out. But thanks for the hint, I might change that.

Edit: I changed my signature to display the flag as colored block elements; if it doesn't show up, at least it shouldn't produce huge empty space anymore.

You should provide such info in your original post.
