Hello all, It does turn out that we were always quite close to having the game run on Mac, it's just a few initialisation and library issues that caused it to fail at booting. With the correct files in the correct folder, it should be possible to run the next Windows build of FreeSO natively on Mac, and perhaps Linux. This does not require a special build of FreeSO, just a few extra files and the new version. On Mac, the game will assume the game files are in your ~/Documents/ Folder, for example: /Users/rhys/Documents/The Sims Online/TSOClient/TSOClient.exe should be the original TSO game executable. The same goes for Simitone, which looks for TS1 in ~/Documents/The Sims/ Preliminary - Trusting FreeSO programs Getting started, you might encounter a lot of roadblocks with Mac trying to stop you installing non-app-store applications. To get around this, open up "Security & Privacy" (findable in spotlight search) and click "open anyways" each time you are asked. Installation Instructions: Download and install mono for Mac here: http://www.mono-project.com/download/#download-mac Download and install SDL2 for Mac (put into Library/Frameworks): https://www.libsdl.org/release/SDL2-2.0.7.dmg Download and extract the windows build of the game as normal. This should go in ~/Documents/FreeSO to work with future applications. The latest build on http://servo.freeso.org (log in as guest) should work as a starting point. Download the Client artifact from here: http://servo.freeso.org/viewLog.html?buildTypeId=ProjectDollhouse_TsoClient&buildId=lastSuccessful&buildBranch=<default>&guest=1 Download The Sims Online files and place the folder in your documents. For Simitone, you can do the same with The Sims. If you can't copy the game from network or a windows drive, you can try downloading with GetTSO.sh by Fatbag from NioTSO: Install cabextract: http://rudix.org/packages/cabextract.html Install wget: http://rudix.org/packages/wget.html Download this partially-broken version of GetTSO.sh that at least sort of works on Mac to your documents folder: http://freeso.org/stuff/GetTSO.sh Open a Terminal and switch to your Documents folder with: cd Documents Add execution permissions to GetTSO.sh: chmod a+x GetTSO.sh Run ./GetTSO.sh. Pick option one every time. Wait for everything to download and extract. Download the Mac Extras zip here: http://freeso.org/stuff/macextras.zip Extract the Mac Extras into your FreeSO folder. Run freeso.command or freeso3d.command to start the game! (these run mono FreeSO.exe through your terminal) You will need to update at least once. IMPORTANT: UPDATING Updating FreeSO is more difficult. After the game's update finishes, the updater will not run. You must run freeso.command or freeso3d.command again, where you will see it performing the update in the command line. Additionally, the game will not properly close until you close the terminal window hosting it. This is pretty unclean, but it works for now. Check back at this thread after updates just to check if this process has changed, or if you need new MacExtras. That's all. All of this is less than ideal, but it should let you play the game without the crippling issues you might get on a VM for now. Hope it works for you! Rhys.
