Can I restore items from a Mavericks Time Machine after upgrading to Yosemite?

If I upgrade from Mavericks to Yosemite, will I still be able to recover items from my Time Machine backup?

Is it safe to `chgrp` of home folder from 'staff'?

I want to be able to share items from my home folder with another testing user account on the same machine.

By default, the group of nearly all items in ~ is staff ... of which the only member is root.

Can I safely chgrp -R admin ~ and chmod -R g+rwx ~ ? Or will this have negative consequences?

(Many of the items I want to 'share' are in ~/Library so I cannot simply put stuff in /Users/Shared)

Why won't Safari save passwords to iCloud

I've been using iCloud passwords for a long time with no issues. This week, suddenly Safari won't remember any new passwords. It still auto-fills previously saved passwords though. In Safari preferences, the box is checked for auto-fill passwords. When I register for a new website, Safari generates a random password as usual, and it says it will remember it in the iCloud keychains, but it doesn't.

I've tried Keychain First Aid, in the Keychain Access app. No problems detected. In Keychain Access, it shows both iCloud and login keychains unlocked. I don't know what the problem could be.

iTunes is changing the number/order of tracks in an album when it loads into my iPod. I want the tracks to stay in order

iTunes changes the number (and therefore) the order of tracks in an album when make a new playlist. Therefore, I cannot listen to an album in the correct order. I want the tracks to stay in order when I create a new playlist. It is worse than shuffle because the actual number of the tracks gets changed, so I cannot tell what order the tracks should be in.

How do I delete a batch of old mail in iOS?

I am seeking help in deleting old mail from my iPad mini running IOS8.1.3.

There are messages back to 2013 (I bought the iPad in December 2012). There doesn't seem to be any way to delete all mail from before a given date, except one by one.

Mail is set up to use POP on that account (my ISP doesn't support IMAP) and set to never delete from server (so they are still there when I get a chance to use the Mac).

PS: It may not matter but on the Mac I use Thunderbird set up to leave mail on the server for 7 days
