4th year with an iMac.
Zero issues.
Sorry folks but there are plenty of Mac viruses out there and Macs get hacked all the time. The days of Macs flying under the radar are long gone.
Businesses that eschew Mac’s because of the added cost would be well served to re-evaluate their cost model. When you factor in security and administration costs, I’d bet the MS malware portal that is called Windows becomes less attractive.
