Can rebooting OS X via software using the Apple drop down menu many times cause any damage to the OS? I'm talking like 3 to 4 times in the span of 40 seconds or so. All properly within software. Also on one of the restarts the menu bars right icons such as WiFi etc. appeared slowly, all the icons kind of populated slowly - has that every happened to anyone else before? And when I just got on my iMac today the mail notification thing was like in the middle of my screen, in stead of the top right. First time it's ever done that. Is there any correlation between that and the reboots? Mods feel free to close this same thread in the El Cap subforums, and keep this one here. Thanks.
