Minecraft Forums

My son has been playing the demo version for awhile now. With his recent good grades, I have purchased the full version for him. I have a Mac running Lion. I logged in after purchase and tried the Download Now button for Minecraft Mac OSX resulting in the following message "Minecraft is damaged. You should move it to trash. When I attempt to play in browser i get the error report below. I have tried deleting the minecraft file and reattempting with no luck. Any ideas would be greatly appreciated!

After a bit more research, it appears that the settings were in my Macs Gatekeeper settings. A few changes and it appears to be working.

Issue: Apple OS X says that Minecraft is damaged or could not be opened
Description: On Apple OS X Mountain Lion (10.8), the error ""Minecraft" is damaged and can't be opened. You should move it to the trash. " This is caused by Apple's Gatekeeper software.
Solution: In System Preferences, select Security & Privacy and click the lock icon that reads "Click the lock to make changes.". Then set "Allow applications downloaded from: 'Mac App Store and identified developers'" to "Anywhere". Start Minecraft.app. Once running, if you'd like, you may reset Gatekeeper to "Mac App Store and identified developers". Alternatively, you can right-click Minecraft.app and select "Open". You'll be presented with a confirmation dialog. You only have to do this once; afterwards you'll be able to double-click and run Minecraft.app without the above steps.
