I, am nerd, in the sense of the word. Now, a lot of people think that Macs are virus free, well, that is frankly NOT true. You see now that Macs are getting more popular, there are now more viruses attacking them, there are not NEAR as many viruses attacking macs as there are PC's however. Now it is true that Macs are technically PCs (Personal Computers), so technically everyone is a PC. Now, there are a arrangement of Operating Systems (OS's for short), just as an example I shall list a few: Windows, Mac OS, Linux, BSD, And React OS. The Most popular of these is Windows, an OS that is riddled with viruses, however cheaper than Mac. Mac OS, One of the most secure OS's around and works great, however a bit on the expensive side. Linux, There are WAY to many Linux distributions to just give a small bit of information, but, I will do my best, it is free, has no viruses, and on the downside, it takes a little longer to get used to. BSD is similar to Linux in most respects. React OS, is a free OS that is windows based.
Now, this is all a little confusing for most, so I narrow down your choices, there are 2 Linux distributions I highly recommend. now if you are a Mac user i recommend, Ubuntu, and if you are a windows user I recommend Kubuntu. Now i Ask you to give me your opinions and I will post more based on your comments, Thanks!
