Hi there,
I just installed Garuda in my iMac (late 2013) and it is working pretty good, along side MacOS (dual boot). For that reason, I've decided that I want to increase my Garuda partition by shrinking the MacOS one.
From what I have read, the way to go is using gparted from the garuda live USB (as mentioned here). Another option is using Mac's Disk Utility (as mentioned here).
I just would like to ask for advice on what is the best way to go in this case.
