Guys i'm not turning this into a Mac vs PC argument like AE vs Losi .You can argue for both sides on there pros and cons
I don't play games and have no need to change the hard drive or PCU as i got the iMac ordered with enough grunt for my own needs , but i do still run Windows on it just for my CC esc and Tekin esc .
I switched from PC after 10 yrs to Mac and never going back .

As stated with a question mark i was not sure if it was an in built feature in the Mac operating system and if i was in the minority for not getting any pop ups ?
