If you travel regularly with your Mac or iOS device, you likely find yourself connecting to new Wi-Fi networks: at airports, in train stations, in hotels, restaurants, pubs, or at clients’ offices. Whether you connect to these networks with your Mac, iPhone or iPad, miraculously, your devices will remember these networks and sync them via iCloud — so your other Apple products can access them too, if you use iCloud Keychain.
Your Apple device’s ability to remember previously connected to networks can be both good and bad. While it means you don’t have to search for or remember login credentials when you connect to a known Wi-Fi network on a different device, it can lead to a surfeit of Wi-Fi networks stored in your keychain and potentially allow you to unknowingly connect to a Wi-Fi network that might not be secure.
You can cull these Wi-Fi networks, but only on a Mac. Read on and we’ll show you how to remove these Wi-Fi networks so your Macs and iOS devices forget them.
Your need passwords to log into websites and services, and it’s hard to remember them. Since it’s a bad idea to use the same password for each different website — because if one site is compromised, hackers will have an email address and password that they can try on other sites — you need to ensure that your passwords are different, and hard to crack. (A recent episode of the Intego Mac Podcast talks about password strategies.)
Your Macs and iOS devices have a “keychain,” which is an encrypted file that stores your passwords and some other information. This file syncs via iCloud, so you can use the same passwords on all your devices. Here’s how Apple’s iCloud keychain works.
Since the launch of the iTunes Store, you could only view your purchase history in iTunes on a computer. You could see a list of purchased items, but not the actual purchase information (dates and prices). Now you can do this.
Go to Settings, then tap your name.
Tap iTunes & App Store, then tap your Apple ID at the top of the screen.
Tap View Apple ID, then enter your password.
Scroll down to Purchase History, then tap that.
Tap any Total Billed line to see more information about the purchase. You’ll see the date and time of the purchase, the address it was billed to, and more. If you want to have a copy of your receipt for a purchase, scroll down and tap Resend, and you’ll receive that receipt by email.
iOS 11 saves photos in the new HEIC/HEIF format by default on the iPhone 7 or later, and the iPad Pro. This format saves a lot of space; photos are about half the size of JPEGs.
Some people are very worried about this; they want to change back to JPEG. You can do this, but you probably don’t need to. (Unless you’re sticking with macOS Sierra; in which case they look like crap.) Update: some photos don’t look good with High Sierra either, so this isn’t just a problem with the operating system.
To make the change, go to Settings > Camera > Format. Choose Most Compatible, if you want to switch back to JPEG. You’ll see a note explaining that you won’t be able to shoot video at the highest frame rate.
iOS 11 is set up so when you transfer files via email, Messages, AirDrop, or any other type of sharing, these photos are converted to JPEG for compatibility.
Some people have had issues importing these files to certain apps. This could be because they diddled with another setting, that’s in Settings > Photos > Transfer to Mac or PC. This setting should remain on Automatic, unless you do want to transfer the original HEIC/HEIF files.
So don’t sweat it; keep on shooting in the new format, which saves a lot of space. Don’t worry about the files being compatible. And if you do happen to come across .heic files, get a copy of the iMazing HEIC Converter, available for Mac or Windows for free.
I got a new iPhone 8 Plus on Friday. I set up the device by transferring data from my backup, and everything worked fine. But there was one feature I wanted to turn on on the new iPhone that I hadn’t used before: iCloud Music Library.
I have a very large music library. And I like listening to my music from my carefully curated and tagged collection. But it’s always been a compromise to sync music to my iPhone. I have such a large library that I can only sync a subset of the music. That’s fine; I don’t listen to that much music on the go. But it’s a lot of work to keep adding and removing music.
While I don’t listen to music away from home that much, I previously had another limit. My phone plan only offered 750 MB of data. I could have paid for more, but I didn’t need it, and plans with more data were fairly expensive from my provider. But a few months ago, my phone provider had an offer: for a few pounds more per month, I could get 8 GB of data.
So I had two choices with the new iPhone. I could either pay for 256 GB storage, or I could settle for the base storage amount of 64 GB (which is finally a fair size). I opted to save the money and use iCloud Music Library.
Note that I haven’t merged my music library with iCloud Music Library; I have a test library that I’ve maintained for many years, starting when iTunes Match was released, on my laptop. So I now can access that library on my iPhone, and my iPad, and I can add and rate music on my iPhone, and listen to music from that library.
So, with the new iPhone, I went to turn on iCloud Music Library. About five minutes later, I saw this:
If you Google this issue, you’ll see lots of “solutions;” most merely suggesting that you keep trying until it works. Well, I tried, and tried, a dozen times; it didn’t work. I called Apple, frustrated, and ended up having three different calls with three advisors, finally reaching a senior advisor. They didn’t know what to do. Since it was a brand new device, it was clear that restoring it wouldn’t help.
While awaiting to hear back from Apple next week, I had a flash of inspiration yesterday. I knew this wasn’t a network problem (the suggestion from Apple advisor #1), or a problem that could be fixed by force restarting the phone (advisor #2), but it had to have something to do with the music database on the device. I’ve seen similar problems in the past that could be resolved by deleting that database; something that you need special software to do.
So I thought I’d try something else. I tried download a purchased album. After the album was on my device, I went back to Settings > Music and tried turning on iCloud Music Library. The process takes several minutes, but I could see that it was happening differently when I went to the Playlists entry in the Music app. There was a progress bar. It was moving slowly, but it did move.
After about ten minutes, I had my iCloud Music Library on my iPhone.
What I think happened is that there was something wonky in the music database, and that downloading an album – even a song might have worked – cleared or fixed it. So, if you can’t enable iCloud Music Library, try downloading a purchased track – if you don’t have any, spend a buck and buy a song – and see if that helps. If it does, please post a comment below so I know if my solution is helping anyone else.
