But Wardle, the discover of this High Sierra error, thinks everyone should update since there's a lot of good built-in security features and this attack works on older versions of Mac OS as well.

Another problem about macOS 10.13 update is the Mac computer overheats and fans keep spinning, making their machine a lot noisier to use.
