Hi , i do not own a mac , but my friend that recently purchased a macbook pro 2011 in june asked me to make garena + warcraft 3 tft work on mac without running any version of windows instead. So after a lot of trouble i came out with a solution. I will describe the problems i encounterred first ,if you are bored you can scroll down to the solution i came up ( i don't know if there is anything else i could do). The problem was that he did not want to rune parallels' version with windows , cause of battery life ( and ram capacity) or whatever else , he just didn't. I read somewhere that crossover could do the job.So i intalled crossover , used it to run garena and then linked to garena the executable path of Warcraft III(Windows version). Then the other problem was the resolution.The macbook was 15,6'' set at 1440x878 , but when we chose this exact resolution at the warcraft 3 resolution list there was always a black bar underneath (i have to note that this was when we ran the war3.exe via the garena that was openned via crossover , when we ran the war3.exe via parallels this resolution worked just fine). The bad thing was that my friend wanted to play through garena so , i came up with this that i did not read anywhere that's why i have to post it here , so others do not spend that ammount of time. 1.You will work with these : Garena , Warcraft III (Windows version) , Crossover and Parallels with any version of windows(used 7 x86). 2.We enter windows (using parallels) and install the original Cds of warcraft3.If for some reason you have lost the original cds you can copy the folder of warcraft 3 from your windows PC and use a program to fix the registry issues ( google registry fixer warcraft 3 something should come up). 3.Run regedit in windows (start, run , regedit) and go to HKEY_CURRENT_USER\Software\Blizzard Entertainment\Warcraft III\Video. At that point you should change the values resheight,reswidth to what you need.But you can read that at every single site telling you how to use a custom resolution.I tried it.It still used 800x600(when running it via garena executable path-settings).I noticed that there were also two other things in there with resolution numbers.So i also changed the values at cinematicheight,cinematicwidth (you can find them also at HKEY_CURRENT_USER\Software\Blizzard Entertainment\Warcraft III\Video) Eventually my numbers where like this reswidth=cinematicwidth=1440 resheight=cinematicheight=1024. After these steps , i quited parallels, ran garena via crossover , openned The frozen throne.exe via garena , and my buddy was ready to play at full screen without having black bars , or losing some sight. About using crossover or parallels , I'm sure you can find guides googling them.
