<< Solved >> Stop Sign on Macbook Appeared!

[sirhot82]

I installed TP-Link 300 Mbps USB Adaptor driver from internet on my macbook. But, after I restarted I got stop sign like below. My computer does not open not. Could you help me how I can fix this problem?

I do not want to loose my harddisk. Do I have to reinstall it, and loose what I already have?

This is a site for those that install Apple operating systems onto non-Apple hardware.
For issues with a real Mac there are many Apple support forums elsewhere or you could take it to the Apple Store.

You can always boot from USB to delete the files that the installer installed.

Or, boot in Target Disk Mode and connect the MacBook Air to your hack and uninstall all the stuff that the installer installed.
