I'm still running on XP, because I find it fairly stable. I restart my machine maybe once every week or two (mainly when I have to apply a software update). I put it in sleep or hibernate mode overnight.
If your machine was dying 2 or 3 times a day, then there was something either seriously wrong with your hardware, or you had a malware infection.
The problem came with memory management. I use photoshop and some of my files were real memory hogs. When I would close the files the memory would not be released. That would build up over the day.
I had very good antivirus and malware detection.
With the Mac that doesn’t happen.
I am not a drone for Mac. I am just a sports photographer trying to get my job done.
I have TEN OSX Macs running at my office. We haven't restarted them in months... They don't hibernate either. Run 24/7. Oh, they've been running now for four years. No anti-virus software and no firewall except the one on the network router.
