comment How can I remove the launchpad?
Complementary to this answer: apple.stackexchange.com/a/146332/8546 – please note that removing Launchpad.app from OS X 10.9.5 does not remove Launchpad functionality.

As you don't use the app, please: why is its existence a concern? The app uses less than 1.5 MB space.

comment Can I have both a case-insensitive system volume and a case-sensitive volume within an encrypted CoreStorage volume?
Side notes, pending edition of the answer: as expected, no automated unlocking of things within an LVG that does not include the startup LV. Undocumented CoreStorage Commands (2011) shows multiple LVFs within a single LVG. Attempts today to resize an LVG, during forward conversion of its LVF, have not succeeded so I wonder whether part of what was undocumented is no longer applicable.

comment How can I rename a Logical Volume Group?
With pre-release 14A361c, a rename of an LVG succeeds without an unmount of its LV.

revised How can I rename a Logical Volume Group?
LVG not LVM; and careful to not confuse LVs with LVGs

comment Can't bind cmd+\ to “Move focus to next window”, but I can bind it to other actions… why?
Not a true answer, but might KeyCue help? Does using the other Command key have the same effect? If you key Command then use Character Viewer to click the on-screen \ key, does that allow the Command-\ shortcut to used where required?

comment Can I downgrade to Mavericks after installing Yosemite?
Some readers may be unaware that OS X Internet Recovery is impossible with some Macs. For my MacBookPro5,2 to regain Mountain Lion (my preference after wiping Yosemite) it was necessary to begin with an Apple DVD for Snow Leopard.

+1 and I'll emphasise this part of Apple's answer: copy any new or changed files. It's as simple, as limited as that; copy stuff. Then a person might try to reuse that stuff, and might get lucky with some of that stuff, but I can't call that a downgrade.

comment OS X Mountain Lion - Kernel Panic and Restart after Sleep
Use an nvram(8) command to add the following boot-arg (boot argument). Then restart the Mac. With this in NVRAM, the next .panic file will be more understandable and informative: keepsyms=y

comment Roll back from OS X Mavericks ( or any newer OS) to Mountain Lion
Migration Assistant in Mavericks explicitly prevents migration from a newer operating system (pre-release Yosemite) – I'll add to the linked question. If Migration Assistant in Mountain Lion can work with Mavericks data, I should certainly treat it as a bug. I can't imagine that the older assistant is designed for that task.

comment Roll back from OS X Mavericks ( or any newer OS) to Mountain Lion
Startup volumes for OS X Mavericks 10.9.4 (13E28) and pre-release Yosemite 10.10 (14A298i) are not recognised by Migration Assistant 5 (521) in Mountain Lion 10.8.5 (12F45). Whether 12F45 can attempt migration from a Time Machine backup of 13E28, I don't know … but considering the nearby answer from @bmike, I should not recommend any such attempt without first fully understanding the possible negative consequences.
