How do i use the thing that can chnage pc mods to mac
You don't change PC mods to Macintosh. They either work for Macs (no *Graft) or they don't. If it is a Mac compatible mod:
Open MPQDraft. Click "Load MPQ Patch", select StarCraft as the Program and Component, and click "Next >". Select "Browse for MPQs" and select the MPQ of the mod. (You can also select SEMPQs.) Make sure there is a check in the box next to the MPQ in the list! Click "Next >" and then "Finish".
If it doesn't work like that on Macs, I can't help you.
Even if it is a memgraft mod, you can still run most of the mod...
Why can't you run all of the changes?
1. Some things changed might require EXE editing in order to function, and crash without it.
2. The exe changed things can't be run without editing the exe, so when you do this you un-do the exe changes.
What do you do?
Same as you'd normally do, make the mpq that's included in the mod into a exe with mpqdraft, and run it.
