Apple’s updated 13-inch Retina MacBook Pro that was released last week received many unfavorable reviews from fans and critics alike. Its supposed main draw, the USB Type-C, the feature that made the big debut alongside the new Apple computer, turned out to be its main weakness as well.

According to The Verge, years of development came down to the revolutionary edition of the USB Type-C, a single port that will serve both power and data requirements. With the absence of various ports scattered around the frame, Apple was able to provide the public with a slimmer, stark design. But while the single port allowed the Retina MacBook to look and think mostly like an iPad, it also came with a couple of unsightly features. A security loophole is one of them.

Type-C is based mostly on the standard USB, making it as vulnerable to firmware attacks as the old models were. Other attacks may also come through the direct access of the memory plug. Type-C’s vulnerabilities to attacks are not new. Unfortunately, modernization was not able to address such an important concern. If we would believe The Verge, it in fact made the problem worse.

On standard computers, users who are worried about potential USB attacks may simply evade the use of the ports entirely. But since it is also used to power up the computer itself, the MacBook Retina keeps the trajectory open for attacks.

On the other hand, it is not all bad for the Retina MacBook, says Techcrunch. The super machine’s Facebook and Twitter capabilities are remarkable. It also features a 5th-generation Intel Core processors and longer battery life. But since Apple fans have high expectations with every new edition that the company releases, they feel that not keeping up with their needs is already a form of betrayal.
