If the disk is encrypted, you’ll see either “APFS (Encrypted)” or “Mac OS Extended (Journaled, Encrypted)” displayed beneath your drive’s name.īut even if your internal drive is encrypted, you shouldn’t assume that your Quick Look cache or any other files will always remain private. When you open Disk Utility, your Mac’s internal boot volume will already be selected. The easiest way to tell if your Mac’s internal drive is encrypted is to open Disk Utility (you can find it by looking in the Utilities folder inside the Applications folder, or by doing a Spotlight search for it by name). It’s important to be aware that your internal hard drive may not necessarily be encrypted there are a number of scenarios in which your Mac’s drive might never have had whole-disk encryption enabled. Shouldn’t that mean that Quick Look previews should be secure? You may wonder why this matters given that every version of macOS since Yosemite has offered to encrypt the Mac’s internal hard drive by default when you do a clean install. This means that anyone who later gains access to the contents of your Mac’s internal drive- even when that external drive is no longer connected-may be able to see previews of all your private files. Whenever you have a drive or disk image mounted on your Mac, even if that disk is encrypted or password-protected, macOS will treat it like any other disk and may cache Quick Look previews of your sensitive files.Įven password-protected disks’ files may be cached by Quick Look. Unfortunately, so far Apple has not chosen to respect your implicit desire for privacy when it comes to Quick Look caching. If you’ve taken the time to fully encrypt an external hard drive, or if you’ve gone to the trouble of creating an encrypted disk image to keep sensitive files private, you’ve made a clear and unmistakable choice to safeguard the files contained within that volume and keep them away from prying eyes. The main issue is that external drives and drives that are no longer mounted- including fully encrypted disks-are cached to the Mac’s internal hard drive.
MAC PHOTO PREVIEW NOT WORKING MAC
While the Quick Look feature is very convenient and not necessarily a concern for most Mac users, highly privacy conscious users may be dismayed to learn that Quick Look doesn’t properly respect users’ implicit desires for privacy, as detailed in a technical article by Wojciech Reguła and Patrick Wardle.
