It could be something like boot cache optimisation preloading more files for caching. On Mountain Lion you can use hardware diagnostics which can be started by holding D before the Apple logo starts showing during boot time.
Unfortunately I didn't use it anymore since the past couple years as Yosemite update made the Clipper's bluetooth connection very flaky and almost useless. Too bad, as built in mic is very handy for calls. Back to the iPhone earpods for laptop calls now...
Now it’s time to move on to aptX receivers — Ugreen 4.2 rocks ;)

Sorry just saw your message. It didn't need any glue, the rubber cover had lip that clips to the frame as is. Never had it accidentally popped off.
But if your really had to, I think some cut of thin double tape would do.
