<p>Eh, compatibility is still a major problem with Macs. Technically, SolidWorks and ProEngineer work on Macs, but in reality, the functionality is pretty bad. Those two programs generally run slower, and I hope you enjoy looking at that rainbow cursor thing, because it comes up all the time. These programs are fairly resource-heavy in Windows, but they’re so slow on Macs that it’s crippling.</p>
<p>Gaming is still bad on Macs. Most of the games that Steam will bring will be previously released Windows ports anyway.</p>
<p>And as far as malware is concerned, Macs were protected by the fact that they had a minority user share. They still do, but that minority is larger now. As such, malware writers already have targeted Macs. The first run of in-the-wild malware consisted of trojans that had to fool the user into installing. However, the malware community knows that Macs are just as exploitable as Windows and Linux. Widespread zero days are coming into usage now. If I had to hazard a guess, I’d say that within two years, the perception of Macs being safe will fade away</p>
