Minecraft – Moving minecraft mods from old Mac to new Mac

macosminecraft-java-editionmods

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?

the error box said Application Support cannot be modified

The Application Support folder in ~/Library/ should always be able to be written to (without asking for special permission) by the user, however the Application Support folder in /Library/ should not. If you try to copy the files to /Library/, it will ask for permission, an indication that something's wrong.

I know you said you are copying them to the same location, but still, make sure you are copying the files to your personal Application Support folder ~/Library/Application Support/. If you copy the files to the global Application Support folder in /Library/, it will not work.
