Today, i finally found a way that works through easy click in wineskin app. I didn't find such tutorial here, so I hope this will be helpful to some mac users. Steps 1. In application folder, right click UO Renaissance.app > show package contents 2. Open Wineskin.app 3. Click Tools tab > Custom EXE creator 4. Type a name for your multiple instance, and /Program Files/Razor/Razor.exe for window EXE: 5. SAVE. After this is done, all you need to do is open your new UO2.exe instance in the .app content package. i didn't know it can work until i research abit today, hope is useful for this forum search.
I found somewhere on the forums a while back that you can literally copy/paste the mac client and then just run them both. That's what I do to run two clients simultaneously. I have UO and then UO2. Both open with their own Razor, etc. Working great so far.
That is the low tech solution that we generally our players, mostly due to my lack of experience with the platform. Thanks for the guide ichiokada! Ill add it to the mac support thread.
