Maths Circus Act 4 - Lion Upgrade

If you have upgraded your Mac to Mac OS X 10.7 "Lion", you may find that Maths Circus Act 4 no longer runs.


If Maths Circus Act 4 is still installed on your Mac, you can download a patch (below) which will upgrade Maths Circus Act 4 to run on Lion. If Maths Circus Act 4 is not installed on your Mac however, you can order a replacement CD if you can provide proof of purchase (see our UPGRADES policy). Otherwise, you will have to buy a new retail package.


To upgrade your Maths Circus Act 4 software, click on the link below to download the patch. The patch is in the form of a ZIP file. When the patch is downloaded to your Mac, double-click the ZIP file to open it. Then copy the unzipped Maths Circus Act file to your Maths Circus installation folder (usually Applications/Maths Circus ƒ by default). Drag the old Maths Circus Act 4 application file to the Trash.


The Maths Circus Act 4 software should then work correctly. Please report any problems to our support team .
