iCloud Keychain is apparently the way ahead, but even Apple has a great deal more work to do before that’s feasible. A look at what’s needed.
iCloud
How is an attacker most likely to get their hands on the secrets stored in your Mac’s keychains, and what can you do to protect them?
macOS has two types of keychain, and its tools for working with them, Keychain Access and the command tool security, only work fully with one type.
It can take many hours for files to be downloaded from iCloud. Apps must be able to cope with that, but how well does macOS?
From Cyberdog in 1996, through iTools in 2000, .Mac in 2002, the dreaded MobileMe in 2008, to iCloud in 2012 – a long and sometimes painful journey.
When should you turn iCloud off to try to solve syncing problems? What use is a Content Caching server? What tools can help diagnose and fix problems?
Its documentation consists almost entirely of how-to recipes. Is there nothing more conceptual so we can understand its apparently random behaviour?
At first it looks like iCloud Drive preserves all xattrs, but actually it cheats and show those stored locally. It’s different when you access the same files from another Mac.
Using local Time Machine backup, iCloud Recovery, and saved versions to recover previous and current versions of files in iCloud Drive, and their limitations.
Why doesn’t Spotlight seem able to return search results for files stored in iCloud Drive? And a strange feature discovered in extended attributes.
