I use unibootin to create a bootable usb with the linux .iso, You can also use Balenaetcher or Mac Linux Usb Loader
I partitioned my ssd external into 3 partitions, 1 800 G with macos journaled + and 1 partition with 100 g in EXFAT, the last one in a little 1 g partition to use as EFI EXFAT
Boot from usb using the ALT key. In ubuntu install the distro. use manual install
use EFI partition as EFI Boot
use the fat32 partition as EXT4 formatted and / as root
Check the disk name eg sda2 or sda3 of the EXT4 volume and select the correct one in the bottom left corner
click on install now and all works perfectly,
An external SSD on a thunderbolt port gives very good performances,
but somethingâs not working⊠or has your audio been resolved?
First, disconnect any external audio devices from your computer. Also disconnect any cables from the USB, Thunderbolt, FireWire, or 3.5mm audio ports.
Apple suggests removing all cables including thunderbolt cables while troubleshooting audio trouble. Please try unplugging the thunderbolt drive and boot directly from the USB installer. Donât install the OS overtop your macOS, just test it.
One thing I donât understand
MacOs has discontinued OpenGl/OpenCL in Catalina which means my graphics card is no longer recognized by Blender 2.8 if I want to use it to render eevee. This is to force everyone to use Metal but Blender guys donât seem to give a hoot.
I installed Windows 10 ( UUUURGH ) and everything worked well in blender with the ATI RADEON 575 PRO
So I thought that a linux bistro would do the same and it doesnât.
Even after forcing an install of the AMD driver instead of the one in linux it still doesnât show up in Blender.
I seem to be destined to install an ugly OS like windows just to have that one feature.
OK Linux has still got a long way to go before non-savvy techs can take it in.
Manjaro seems really good but alas, no sound coming out of the speakers. I did get the ATI card to install a non xorg version but that ended up in a black screen boot up., no way of force booting seeing that the keyboard is a macintosh
Coming from the Mac world where everything JUST works, itâs a little dissapointing. I actually really like the way one can totally customize KDE or Ubuntu, but Iâm not ready to go back to school and start to learn programming just to get my sound card to work.
If someone finds a way to get the sound and ATI Radeon cards to work on an iMac 2017 27" I will be much appreciated.
Very true, thatâs the reason I want to try something else. I find Ubuntu Budgie or Kubuntu very beautiful and it works great on an old MacBook,
What is not so good with Apple is that they decide to change something, like their graphical language Metal , or discontinue OpenGL or whatever and they expect the whole industry to follow in their decisions,
I also really like the idea that Linux is open source.
I just need some help on the hardware side, but Iâm really getting tired of reading and trying a lot of tips that donât seem to work.
Alain Iâm sorry there doesnât seem to be a ready solution (and a little worried for my longer term plan, actually!) If you wanted to eventually move off of macOS/Windows, I suppose you could always sell it and buy/assemble something that would suit you more? I have a number of friends who love love love their mac hardware but just canât bring themselves to buy another apple product. Youâd probably get a good $$ locally on kijiji.
Go to About this Mac under the Apple Logo top left corner
The first display will show a circle icon
your macOS version and model of mac
CPU
RAM
GPU
we donât need the serial number, but it will also be there.
If you open the system report at this point (thereâs a button) you can drill down deeper into stuff like your wifi card, audio, controllers - all the mechanics
I still think itâs the Thunderbolt connection. My neighbour is a research scientist at the University of Toronto, and he loves his mac equipment. He was very disappointed when Apple updated the hardware on a new purchase and he lost the ability to connect to a second Apple Display Monitor in his department. It needed a new kind of cable adapter, but he was dismayed to find the new Thunderbolt connection didnât transfer audio to the speakers in the previously awesome monitor.
I think FF is correct - we might go back and forth on this endlessly without having some hands on. Did you have a chance to boot directly from the USB installer into the iMac?
I know you previously said you installed Ubuntu Budgie on an external Thunderbolt drive, and that you were very happy with it. I wonder if the issue is that your audio instructions arenât transferring through the Thunderbolt connection the same way my neighbourâs audio wasnât transferring through to his Thunderbolt monitor.
Well now then I will need to make a bootcamp on my internal drive to install Ubuntu,
I prefer the external SSD because it keeps my hard drive clean,
Maybe it is the thunderbolt cable, Iâll have to check it out
The bluetooth headphones solution actually works well so Iâm going to stop trying to get it working.
For the moment Iâm going to see if I can really use it on a daily basis. I am really impressed at Manjaro, it is really customizable and versatile . Thanks for the help.
maybe one day Iâll get a new tip and itâll work
FF is correct, DON"T install Ubuntu Budgie on your iMac â you are merely using the USB installer to test your hardware against the audio drivers that are already present/built into the installer. You are trying to eliminate the Thunderbolt cable as the source of your audio trouble.
IF the audio works directly from the installer, then you can troubleshoot from there.
Although you do seem cool enough with your bluetooth solution: could you pick up some bluetooth speakers and call it solved?
