Mac updating boot caches
Its not really critical, just reboot and the caches are automatically rebuilt.
Hi, I just upgraded to Leopard from Tiger last night on my 15" Macbook Pro (2.16ghz).
The scheme also measures the cache hit rate, and stores the request pattern into a "history list" for being adaptive in future.
If the hit rate is too low, the caching is disabled.
I also did a software update after the installation.
Ever since, whenever I restart or shut down, I receive a message saying "Updating Boot Caches" "Caches necessary for booting are being updated".
Let’s learn a bit more and see how to boot into safe mode, what safe mode does, and how to exit and return the Mac to it’s normal boot state.
And yes, this works in all versions of OS X, from Yosemite to Mavericks, Mountain Lion, Snow Leopard, you name it, you can boot into safe mode with it.
Sometimes the system will hang at a specific boot screen such as the gray Apple, or at a blank blue screen.
Generally you’d only want to trash caches if they’re hogging a large amount of storage capacity, or if a particular app is not functioning properly or is serving stale data served from old cache.
Despite what some “cleaner” apps might claim, cleaning our Mac cache and temporary files is not going to give your computer a magical super performance boost or make you more popular with the ladies and gents, all it does is remove temporary files from the computer.
Sometimes it might help particular app performance, but usually it does not.
If you don’t have a specific reason to clear Mac caches, don’t do it.
