Apple Numbers appears to display a + instead of a / or ÷ for the division formula

I'm on Mojave for a while (Aperture) so I get to use an old version of Apple's spreadsheet - Numbers 10.1 (6913). It think this is still true however.

If I type a formula that divides one cell by another the Formula bar shows this:

It is actually doing division, but instead of a / or other operator it seems to displays a +.

If you add the same too numbers the formula  bar shows

A 2015 Discussion post explains the problem. This is an artifact of using Numbers on a non-Retina display with the default Numbers font. The first screenshot is actually a ÷ symbol. It's just super hard to see for an Old person using a non-Retina external monitor. (Did they even have Retina displays in 2015? Maybe Apple Devs had them?)

I suspect it's never been fixed -- so I'm gonna call this a bug. Apple is such a weird company and Numbers is weird even for Apple. There are many things I like about it but every so often something like this shows up. (Also, the Help function reminds me how bad macOS Help is.)

FWIW Numbers has an ePub User Guide and an online User Guide (version 12, but you can tweak the URL and seems to show 10.1).

Migrating from an Apple Store/iTunes shared media Apple ID to a standard Apple ID configuration

I'm putting this up as a peacekeeper. I hope one day I'll fill it in better, but if you are trying to migrate from a shared Apple ID to each family member having only one Apple ID for both iCloud services and media then you will welcome any information.

First, see my prior post. I'll continue with this convention:

Let's say my iCloud Apple ID was "Sam" and my Media Apple ID was "Linda". So my device Apple ID configuration was Sam/Linda.  After the change it was Sam/Sam. 

I think the migration will more or less work. This is what I did so far, omitting errors and redirections:

1. Let my Apple Music subscription lapse and cleaned up other subscriptions. These were owned by "Linda".
2. Subscribed to Apple Music one day after the lapse using Sam. I'd seen hints Apple keeps iCloud media data (playlists) around for at least 1 month post lapse of subscriptions. I can confirm they last at least 1 day.
3. Changed my devices to be Sam/Sam (maybe this would best be done later)
4. In iCloud Family Sharing settings opened settings for Sam.  Even though my device might be Sam/Sam when I inspected details on my Family Organizer Apple ID I could see shared access was mediated by Linda. I changed that to Sam in Family Sharing.

I ran into too many issues to enumerate. A few tips:

1. Changes to media rights seem to take time to be effective. After starting a subscription give it at least 30-60 minutes.
2. iTunes classic allowed import/export of XML playlist files. These are useless. The key identifier is the track ID so they only have meaning for the Library they came from.
3. Sharing a playlist by URL from Monterey worked -- but not at first. It got hung up in the subscription translation.
4. Even after family members had renewed subscription access they needed to do something to get Apple Music.app to synchronize. Sometimes this was clicking on the sign-up add for Apple Music then choosing the subtle link for "already have a subscription". Sometimes shutting down and restarting. Sometimes looking at Music.app preferences and turning on iCloud library synch. (Sorry, there were so many issues!)

Extra comments

1. There are two kinds of Playlists - "Apple Music Playlists" and traditional iTunes/Music playlists. I think when you migrate an old iTunes library to Monterey the app turns legacy playlists into Apple Music Playlists. Not 100% sure about this.
2. I'm not gonna talk about this more, but I'm still running iTunes on Mojave and I'm amazed it works at all. It more or less survived the process. I have future work to do around migrating things out of iTunes on Mojave. (That machine will be an Aperture machine until I migrate that -- an even greater challenge. Then it will likely be replaced.
3. Post migration it's not clear how to identify what a Family Member purchased from the days of the shared Apple ID. Apple suggests going to reportaproblem.apple.com; it only goes back 90 days though. Before doing the Apple ID migration the Family Organizer view had data broken down by family member, but after the migration that was very limited.

Update 11/15/2022 - the dreaded Apple ID for purchases". 

Only my #1 son still had the "Linda" Apple ID for purchases (Store, Media). He's on iOS 16.1.1. Even after switching his Media Apple ID to be his iCloud Apple ID, and despite his Settings Family Sharing saying he had access to the Apple Music subscription, both iTunes.app and Music.app said he didn't have family sharing access.

I found https://support.apple.com/en-us/HT201454. There are 3 Apple ID settings in iOS, not 2. There's iCloud Apple ID, Media and App Purchase Apple ID, and for the Family Organizer there's also Apple ID:Family Sharing:Purchase Sharing:Purchases:Apple ID for Purchases! The last is not updated when a user changes Media Apple ID. It's a "secondary Apple ID".

I don't think the Apple ID for purchases always exists. On my son's phone it can be changed. On my personal family organizer phone it appears it cannot be changed and it's incorrect. There can be significant timing delays when it's changed, the Done button may appear not to work but on screen refresh it may work.

After I removed the secondary Apple ID for purchases from his phone he was able to access Apple Music. Then I could enable "Sync Library" in Music Settings.

Update 11/18/2022: Article on the secondary Apple ID and purchase sharing. This article changed 9/2022. It feels like Apple's attempt to mitigate the multiple Apple ID curse. You can only change this every 90 days. I changed it from "Linda" to "Sam" but in 3m I might change it back again -- after some research.

Update 11/19/2022

After doing the Apple ID separation I needed to recreate a Library for my son that identified what he'd actually purchased over the years that his purchase were on the family shared Media Apple ID. The Media Apple ID had its own account on one of our Macs, so I could create a Playlist from that to share, then open that shared url in his current Library. That worked pretty well in the end, but there were many issues and steps. I used many macOS Music app queries and sorts to reconstruct which things were his (He still purchases Music from Apple. That's a longer story.)

Once he had the Playlist I created open in his macOS Music app I had to select all songs and use "Add to Library" to actually make them part of his Library. Note you can download songs for a Playlist but that doesn't make them part of the Library. I needed his Library to reflect his purchases and preferences.

As a part of this process I found the best way to view purchase history was to enable iTunes in Apple Music, then in iTunes click the Purchases link.

Incidentally I ran into many UI bugs and issues with Apple Music. The worst is the insane and inexplicably persistent Apple Music product manager decision to use an enormous Playlist header section that makes the essential column browser very inefficient. There were problems with Authorizations, with downloads, with list row selection and more. It's just a buggy and flaky app. At one point I was trying to download locally and nothing happened. Only by showing the Activity window could I see that my device authorization wasn't working. I had to use my son's Apple ID to authorize Music / iTunes in his user account -- perhaps the Apple ID I first used had too many authorizations on it. There was no error message.

AppleScripts to speed Java compile and execute with BBEdit

Students are often asked not to use an IDE (I like Visual Studio Java) for their Java projects. Instead they need to use BBEdit without an IDE. BBEdit does not appear to natively support facilitated compile/execute but it does run AppleScrips that can speed things a bit.

The davalign.com site has some scripts written for TextWranger. If you rename them to BBEdit they work well.

Reproducing them here in case that site vanishes. I didn't see much like this. Note if you open and save in macOS Script Editor they will be compiled. I like that the first action is to save the document, it's easy to forget to save before a compile.

Compile java.scpt

tell application "BBEdit"

save text document 1

set the_file to file of text document 1

end tell

set AppleScript's text item delimiters to ":"

set source_file to the last text item of (the_file as string)

tell application "Finder"

set the_folder to container of file the_file

end tell

tell application "Terminal"

activate

set p to POSIX path of (the_folder as string)

set shell_script to "cd " & (quoted form of p) & ¬

"; javac " & source_file

if (count windows) is 0 then

do script shell_script

else

do script shell_script in the front window

end if

end tell

Run java.scpt

tell application "BBEdit"

set the_file to file of text document 1

end tell

set AppleScript's text item delimiters to ":"

set source_file to the last text item of (the_file as string)

set compiled_file to text 1 thru -6 of source_file

tell application "Finder"

set the_folder to container of file the_file

end tell

tell application "Terminal"

activate

set p to POSIX path of (the_folder as string)

set shell_script to "cd " & (quoted form of p) & ¬

"; java " & compiled_file

if (count windows) is 0 then

do script shell_script

else

do script shell_script in the front window

end if

end tell

Apple Music subscriptions stop working when I changed my Media & Purchases Apple ID

Apple digital rights management (DRM, FairPlay in this case) is very complex, particularly when one adds Family Sharing or has an atypical Apple ID setup.

In our case, for reasons that made sense 10-15y ago, my iCloud Apple ID is different from my Media & Purchases Apple ID. My iCloud Apple ID is the family organizer and my Media Apple ID is a family member.

Over the past few years I've been trying to migrate to using a single Apple ID on my phone. I have migrated all but one family member.

Migration has been difficult. I don't think Apple has published a transition guide. You can't, of course, transfer purchases or media or subscriptions. There's a risk of losing a lot purchases and Apple is unlikely to help.

I looked at doing a test migration on a macOS Monterey account of mine but it seemed Monterey did not a user to change only their Media Apple ID. [Later I found you can. In Monterey, unlike iOS, it's obscure how you do this; it doesn't show up in an Apple ID. You change the Media Apple ID through the App Store (Sign Out, Sign In).]

Since it seemed couldn't test on Monterey without trying a full Apple ID transition I made the changes on my iPhone.  Let's say my iCloud Apple ID was "Sam" and my Media Apple ID was "Linda". So my device Apple ID configuration was Sam/Linda.  After the change it was Sam/Sam. Sam is the Family Organizer, Linda is a family member. Linda owns our app and media purchases -- at least that's where they show up when I look.

I was particularly curious how Apple Music would work including test playlist sharing. Unfortunately I couldn't test the playlist sharing because Apple Music didn't work at all! As far as iOS was concerned I didn't have an Apple Music subscription. It offered to give me 6 months free. I also didn't have any Playlists or other configuration. Music (iTunes) configuration is tied to the Media Apple ID, not the iCloud Apple ID.

To recap, Sam is family organizer and Sam/Linda purchased the family plan Apple Music subscription. Linda shows up in Family Sharing as a family member. Once I became Sam/Sam I had no access to Apple Music. Reviewing Family Sharing it appeared that Sam should have access to Linda's Apple Music subscription. That doesn't work.

Apple's Family Sharing problem support page says:

... Make sure that you're using the same Apple ID for Family Sharing and Media & Purchases... 

They don't say how to migrate to that idea of course! Obviously it was possible to use a different Apple ID for Family Sharing and Media (Apple Music worked before). I don't know if the changes made to my device impacted any other family members (wish I'd checked!), but it appears for a Family Organizer device to see Apple Music they have to use the same Apple ID used at time of purchase.

Somewhat surprisingly Apple let me revert back to Sam/Linda on my iPhone. (I think there was some time limit/change limit on Apple ID media changes.) After a period of sync I had my old playlist and Apple Music access.

My guess is that to make the change to Sam/Sam and keep Apple Music I'll have to end my current subscription (tied to Linda) then change the Media Apple ID then resubscribe for the family. (In practice I'll end all subscriptions for Linda before the change.)

Expelling demons from 2020 Air: when Disk Utility says to run against the Container (and more)

If you have to maintain a modern Mac, it helps to be retired. How else would I have hours to spend one Friday pm?

The 2020 Air I inherited from my daughter had met with a beverage at a bad time. We paid a third party to resurrect it (Apple doesn't touch wet stuff) but the machine seemed quirky in a software way. Maybe related to the T2 chip and doing the battery swap and then (mistake) Migration Assistant from my ancient Air.

First I had to fix the VoiceTrigger bug, but the machine was slow and I kept running into weird sh*t, like being unable to enable the default App Expose gesture.

So I decided to cleanup by removing files on that machine (they are still on my working Air) and also clean up the user library. I removed a lot of 2007 and earlier items, including a RAZR plug-in. Maybe did nothing but didn't take long.

Then I ran Onyx and it complained the disk was corrupted. When I tried to run Disk Utility I ran into the SMC reset bug.

Once I fixed that Disk Utility would run, but it complained about a corrupt snapshot on my Data drive. Deleting the snapshot didn't fix the error though, so it's likely a red herring. The message said to run fsck on the Container, but I didn't see how to do that. Running it on the Volume didn't help.

The Disk Utility directions were, of course, wrong. As were various web sites that said to try fsck in single user mode (is single user even possible in Monterey?).

Eclectic Light had the best guidance, but the real missing piece was telling Disk Utility to show everyone, not just Volumes. That showed me the Container so I could run DU there; the details console shows it's running fsck_apfs -y -x /dev/disk0s2. It ran against all the /dev/disk* things and fixed them all, exiting successfully. My App Expose gesture returned.

I think the demons are purged for now. macOS is pretty damn fragile these days ...

Monterey T2 bug - First Aid, unlocking disk, operation canceled - Do an SMC reset

When I tried to run Disk Utility on my 2020 Intel Air running Monterey I got:

    Running First Aid on ..

    Unlocking Disk

    Operation Canceled. 

Google found exactly one reference to this in a 2021 Apple Discussion post with a link to an Apple Support article that has since been removed ...

... That turned out to the known issue linked with the T2 Security chip (https://support.apple.com/en-us/HT203127).  Resetting the SMC solved that problem as well as the original problem with the hard drive.

Resetting SMC (I used two methods) fixed the bug and First Aid was able to continue. (There are other problems, but at least this one was fixed.)

I don't know if this insanely rare or if Google simply isn't that useful any more (probably both). Resharing here.

Managing multiple Apple Store Apple IDs in Monterey: how to sign out and thus change default Apple ID for app update and purchase

There's a lot of complexity in Apple's software, but my nomination for the ultimate complexity is the web of undocumented and slowly changing rules and tools around Apple's Digital Rights Management (FairPlay) including rights to use media (music, video) and software (apps) for both individuals and family members.

I don't think anyone truly understands it all, not even Apple's senior developers. Sometime in the past decade Tim Cook said he'd fix the Apple ID problem and then things went silent. It's a nightmare. I remember when changing a phone number associated with an Apple ID could switch the ownership arrangement for device history (presumably a matching problem between disparate databases).

My most recent experience with this was trying to fix the default Apple Store Apple ID used to for Mac App Store DRM on my wife's Air Monterey account. It was defaulting to an Apple ID we used to share for iTunes purchases 10+ years ago. I've been slowly disentangling it for 4 years now and the rules change with each macOS/iOS release. Currently there's a bit more tooling to sort out who owns what on a Mac but it's obscure.

As far as I can tell the controls for this are now hidden in the App Store app. That kind of makes sense, because the rules (and Apple's DRM contracts) for movies/TV, music and apps are all likely different. You have to go into the App Store app, which can show the apps associated with multiple Apple IDs, then you have to sign out from the menu:

After signing out the default account for App Store purchases was her Apple ID.

Her Music account seems to be based on her Apple ID, but I didn't check to see if changing the App Store Apple ID changed that too. It would make sense if Apple were to have separate rules though. 

I think the complexity of Apple ID DRM may be one of the reasons Apple never provided a multi-user iPad for families. (Our shared iPad has its own unique Apple ID but is a member of our family sharing.)
