I've not been able to install 25.04 onto both a mid 2011 iMac and a late 2013 imac:

When booting off a USB drive with the iso (25.04), it hangs after the grub screen (with just a black screen and steady cursor in the top left). I removed "quiet splash" from grub and it seems to hang after "EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path". I also added the nomodeset parameter to grub but that didn't help. Choosing safe graphics also doesn't work

I tried upgrading by using the command do-release-upgrade -p and the same happened (on rebooting it hung in the same place).

Out of interest, I also tried installing Kubuntu 25.04 (from a USB stick) and got the same.

I verified the checksum and checked the ISOs after downloading them so I'm fairly sure they are good.

Tried using 2 different USB drives.

These appear to be the same problem:

  1. Upgrade Ubuntu 25 -> iMac 2011 Failed, Installation Ubuntu 25 -> iMac 2011 Failed
  2. Installation on MacBook Pro 2013 Fails
  3. After upgrading to 25.04, I have two Linux-images in GRUB, but I can only boot into one of them
  4. Ubuntu 25.04 bricked my 2015 macbook pro

In the meantime I've gone back to 24.10.

Any ideas?

  • Does it work when you run it with the nomodeset parameter in grub? – Archisman Panigrahi Apr 19 '25 at 14:18
  • Thanks - I did try that and got the same. – Guy Apr 19 '25 at 14:54

    I definitely appreciate you reposting this as a question. For the moment, I've been asked to close it based on, as I think you've seen, the MAJOR Known Issues with Upgrades - Known Active Issue. Keep watching that Meta post for updates. – NotTheDr01ds Apr 19 '25 at 21:17

    Could this please be reopened as it's not one of the 4 installation problems with 25.04? There seems to be a problem installing 25.04 on any macs (macbooks, imacs and mac minis). It seems to be related to the kernel being used.https://www.reddit.com/r/linux_on_mac/comments/1k2lbyq/ubuntu_2504_bricked_my_2015_macbook_pro/ – Guy Apr 25 '25 at 10:03

A fix has been implemented and you can now upgrade from 24.04 or 24.10 to 25.04. However, the bootable ISOs for 25.04 have not been updated so to get 25.04, you have to upgrade from 24.04 or 24.10.
