I haven't played in a week, spending my time searching for that solution. I owe her a solution to keep playing the game. I dragged my wife into the game, ignoring the red flags around the engine, and now she plays way more than I do. I did investigate a W10 boot but you know, it runs into even more issues on this old hardware. The old Radeon cards have been a problem since at least 2013, and I'm not keen on installing a 2010 Linux out of LTS for kernel-driver compatibility.

(Late edit for typos and said:Update: None of the information I could find on the web has been reassuring. This is where I am, researching the matter and trying to make sure that the OS will be able to use the Radeon for more than the basic graphical functions. From what I could read it is not advised to install manually the manufacturer-provided Linux driver for the oldest Radeon cards, but the open source driver is a problem too unless one downgrades the OS. Upon reboot I get the black screen again unless I start in recovery mode. I allotted 4GB for the swap partition, I can enlarge it if necessary. I was able to install LXLE and let it download what it needed for adjusting itself. After some research I learned that I should boot with the option 'nomodeset' because the Radeon card is a problem - this much I had been fearing from the start. I booted from the flash stick and quickly sank into a black screen. 90% of the Linux space will be for the GW2 files, and 10% for LXLE and WINE. I partitioned the one drive using the Mac's built-in utility. It goes by the name LXLE, and I put the image on a stick with Rufus. I finally picked a minimal Ubuntu with some history record that may be more likely to make things easier. For a moment I considered Tiny Core Linux but was afraid I would run into compatibility issues.

Due to the limited storage, I decided to leave Mac-flavored distros for later. So, this computer is an iMac from around 2010 with a Radeon graphics card. Much appreciated! I am going slowly and will document my adventure here in case it can benefit someone in a similar situation.
