Problem Installing Ubuntu on an older iMac w/ Wireless Logitech Keyboard/Mouse

Trying to install Ubuntu this evening on my mother-in-law’s old iMac that my wife has had for a few years; no longer update supported. I flashed a thumb drive with the Ubuntu LTS using Balena Etcher. I’m also using a new wireless Logitech Comfort Wave Keyboard/Mouse combo that is otherwise working fine on the Mac OS (made sure to identify keyboard w/ the system). As this keyboard is slightly different in keyboard configuration than a regular iMac keyboard, I had to go into the keyboard settings and assign the Windows key as the Option key (in Mac OS) so that I could attempt to boot into the Boot Menu). I ejected the USB, sys shutdown, reinserted USB, and immediately pressed & held the Option key (reassigned Windows key) and attempted to go into Boot Menu. I did this 3 or 4 times to no avail.

I then scurried the internet for a solution. I found a couple older suggestions w/ other Logitech keyboards that suggested moving the keyboard/mouse USB receiver to the USB port closest to the middle of the iMac. Still no success.

Does anyone out there have any suggestions? It would be much appreciated.



I went back into keyboard settings (“Modified”) and reset to default. I then used the “Alt” key (pressed down) at start-up and booted right into the Boot Menu. Apparently I never had to reassign a key on my Logitech keyboard as the “Option”. It was already the “Alt” key.

Installing Ubuntu Linux OS on our older iMac right now! Woo-hoo!!!


Glad you got that figured out! Let us know if you need any help with anything else!
