I have an old Macbook with Minecraft 1.5.2.
I have several dozen mods I use daily.
I just got a new Macbook Pro and downloaded the Minecraft app.
It works fine.
But I need my mods. So I went to the old Mac's Library- Application Support- Minecraft folder and copied it all to an external drive. I then loaded all those files from the external drive to the same location on the new Macbook. But when I run Minecraft the mods do not work.
When I moved the files from the desktop of the new Mac to the Application Support folder, the error box said Application Support cannot be modified. So I went to the folder permissions and changed them to Read and Write. The files are now able to be moved, but are still not working.
What did I do wrong?
