** Updated guide for Mojave users ** Hey guys, so with the help of others in this thread that have mentioned wine updates and simply installing wine and running PSO is simple now. So I will just put the new guide here where it can be found easily and requires way less effort and techie-ness than the OG guide. Should work in Sierra but I cannot test that so no guarantees and remember not to set your resolution crazy high or it will crash! First I will note that I am running a clean install of Mojave on osX ver.10.14.2 and had zero complications with a successful run. I will keep things to point form to keep it short: 1. Download and install Xquartz from here:https://www.xquartz.org/ - Follow the prompts and reboot for good measure 2. Download and install Wine ver. 3.0.4(or latest version) from here: https://dl.winehq.org/wine-builds/macosx/download.html - Select the "Stable" installer. Once downloaded, click to run it and install wine automatically. Just follow the prompts and when it asks you to install libraries just say yes. 3. Download the Ephinea_PSOBB_Installer.exe if you haven't already. Wine should have converted this file and changed the icon. Just double click to install and wine will do the rest, just follow the prompts and keep everything default. 4. Unhide your hidden files by going to Terminal and typing: defaults write com.apple.finder AppleShowAllFiles YES - You can hide them again by replacing "YES" with "NO" 5. Navigate through your file directory starting from your main HDD. Go to the menu bar and select: Go > Library. Follow image for navigation. NOTE: Users and HDD names will differ. 6. Make an alias(shortcut) of the EphineaPSO folder, a duplicate will show beneath it. Drag that to your desktop and hide your exposed files again with the code provided in terminal. And thats it! To run the game just simply open the folder on your desktop and double click on online.exe Thats it! Good luck and have fun! *ORIGINAL POST BELOW* Hello all! I have some good news for Mac OS X users who want to play PSOBB. I found a tutorial online about running Windows programs on OS X with Wine and Homebrew, gave it a try and I have been happily playing on the Ephinea server crash/lag free. The only quirk is a shader isn't loading proper but it is not game breaking, you can still see all the textures and lighting fine. The source tutorial itself is easy enough to understand and is pretty straight forward if you are familiar with navigating around your Mac via Terminal with command lines. The PDF guide I compiled is sourced from the tutorial I used as well as my own input to make it more user friendly for people who are not comfortable with Terminal or for people who find the source material confusing. I tried to make it as straight forward as possible and hopefully easier to understand. Feedback on the guide is always welcome as I am sure I can improve it as needed. Also any questions anyone may have I will try my best to help. It should be noted I have only been running PSO with this set up for the last 4 days now, so I am still testing it and seeing how it holds up. So far so good! Just be weary when setting resolutions from the launcher, some settings will crash the game if you go too large. Keep it moderate Good luck UPDATE: Since this was originally posted, I have been running crash free so far even with server updates.
