We can talk about even more general idea of saving file space: compression. Ever heard about it used across the whole filesystems?

Microsoft MS-DOS and Windows supported this in the 90s with DriveSpace, and modern file systems like btrfs and zfs also support transparent compression.

I have a fun one: my iPhone (12 Pro) refuses to acknowledge that it has eSIM functionality, even though the hardware exists.

I'm fairly sure I know what the problem is! It was restored from a backup taken on an iPhone X that had two physical SIM slots (Chinese version). The new phone now seems to think it has two physical SIM slots: it shows an IMEI2 in About, but any attempt to use the eSIM functionality just fails (scanning a code does "nothing"; no "add" button is visible, etc.).

If this was an Android phone, I'd root it and just fix the offending network configuration file. I believe it's possible to tamper with a backup of the phone to fix the issue, but this would mean a full backup+restore cycle and some specialized tooling to go mucking with the backup.

I filed a Radar on it ages ago, but I'm assuming nobody ever picked it up.

Issues caused by restoring from backups were super common in the early iOS days. It makes me wonder how many weird bugs can be fixed these days by starting from scratch instead of migrating years of cruft through backup/restore.

Apple has a solid hardware business and massive profits from their App Store tax, they are not dependent on ad business in the way Google is. Very different incentives.

They might not be dependent on ad revenue, but they are a greedy company that will not leave any money on the table. Next year, more ads are coming to the App Store that already generates a profit of over $10 billion/year: https://9to5mac.com/2025/12/17/apple-announces-more-ads-are-...

It's interesting that apple released 3rd party Wi-Fi Aware SDK for iOS and iPadOS but no for MacOS...

praseodym · 3 months ago

MacOS doesn’t have a gatekeeper status in the Digital Markets Act (DMA), so Apple doesn’t need to provide it. This shows that they only provide the SDK because of regulatory pressure, and try to maintain their vendor lock-in where possible.

This is used to prevent devices that don’t know about those features from accidentally triggering them as they are not per spec (spec lacks way to do many things AirPods do).

And AirPods do connect to non Apple devices. They are just limited to doing what BT spec allows and no more

Please stop spreading FUD

Multipoint connectivity is part of the spec but apparently AirPods only support it if you pretend to be an Apple device.
