Hi, I got a 2013 iMac from a friend. I decide to shrink the Mac OS partition and added Zorin.
It’s been a while and really never used the Mac OS, so finally decided I would remove that partition and expand the Zorin partition to use the whole drive.
I installed GParted and figured I could easily do that, by formatting the MacOS partition and then expanding the Zorin partition.
Problem is that when I’m booted from Zorin, it won’t let me change the size or move that partition.
OK. So, I figure I have to boot from a live USB so that the Zorin partition is no longer active.
Apparently, to boot a Mac with a USB, you have to use a USB keyboard and hold the Option key during boot. I only have a Windows USB wireless keyboard and I’ve tried holding the Windows key or the Left ALT key but no luck. Not sure how I got it to work the first time,but it’s been quite a while.
Is there any trick I’m missing?
